THE PROTOCOL OF 1988 RELATING TO THE INTERNATIONAL CONVENTION ONLOAD LINES, 1966 AND INTERNATIONAL CONVENTION ON LOAD LINES, 1966 REVISEDBY THE PROTOCOL OF 1988

THE PROTOCOL OF 1988 RELATING TO THE INTERNATIONAL CONVENTION ONLOAD LINES, 1966 AND INTERNATIONAL CONVENTION ON LOAD LINES, 1966 REVISEDBY THE PROTOCOL OF 1988 Regulation 42 Definitions (1) Timber Deck Cargo The term "timber deck cargo" means a cargo of timber carried on an uncovered part of a freeboard or superstructure deck. The term does not include wood pulp or similar cargo.

(2) Timber Load Line A timber deck cargo may be regarded as giving a ship a certain additional buoyancy and a greater degree of protection against the sea.

For that reason, ships carrying a timber deck cargo may be granted a reduction of freeboard calculated according to the provisions of Regulation 45 and marked on the ship's side in accordance with the provisions of Regulation 6 (3) and (4). However, in order that such special freeboard may be granted and used, the timber deck cargo shall comply with certain conditions which are laid down in Regulation 44, and the ship itself shall also comply with certain conditions relating to its construction which are set out in Regulation 43.

Regulation 43 Construction of Ship Superstructure (1) Ships shall have a forecastle of at least standard height and a length of at least 0.07 L. In addition, if the ship is less than 100 meters in length, a poop of at least standard height, or a raised quarter-deck with either a deckhouse or a strong steel hood of at least the same total height shall be fitted aft.

Double Bottom Tanks (2) Double bottom tanks where fitted within the midship half length of the ship shall have adequate watertight longitudinal sub-division.

Bulwarks (3) The ship shall be fitted either with permanent bulwarks at least 1 metre in height, specially stiffened on the upper edge and supported by strong bulwark stays attached to the deck and provided with necessary freeing ports, or with efficient rails of the same height and of specially strong construction.

Regulation 44 Stowage General (1) Openings in the weather deck over which cargo is stowed shall be securely closed and battened down.

The ventilators and air pipes shall be efficiently protected.

(2) Timber deck cargoes shall extend over at least the entire available length which is the total length of the well or wells between superstructures. When there is no limiting superstructure at the after end, the timber shall extend at least to the after end of the aftermost hatchway.

The timber deck cargo shall extend athwartships as close as possible to the ship's side, due allowance being made for obstructions such as guard rails, bulwark stays, uprights, pilot access, etc., provided any gap thus created at the side of the ship shall not exceed a mean of 4% of the breadth. The timber shall be stowed as solidly as possible to at least the standard height of the superstructure other than any raised quarterdeck.

(3) On a ship within a seasonal winter zone in winter, the height of the deck cargo above the weather deck shall not exceed one third of the extreme breadth of the ship.

(4) The timber deck cargo shall be compactly stowed, lashed and secured. It shall not interfere in any way with the navigation and necessary work of the ship.

Uprights (5) Uprights, when required by the nature of the timber, shall be of adequate strength considering the breadth of the ship; the strength of the uprights shall not exceed the strength of the bulwark and the spacing shall be suitable for the length and character of timber carried, but shall not exceed 3 m. Strong angles or metal sockets or equally efficient means shall be provided for securing the uprights.

Lashings (6) Timber deck cargo shall be effectively secured throughout its length by a lashing system acceptable to the Administration for the character of the timber carried*.

[* Reference is made to the Code of Safe Practice for Ships Carrying Timber Deck Cargoes originally adopted by the Organization as resolution A. 287 (VIII) and amended by the Maritime Safety Committee at its thirty-ninth session.] Stability (7) Provision shall be made for a safe margin of stability at all stages of the voyage, regard being given to additions of weight, such as those arising from absorption of water or icing, if applicable, and to losses of weight such as those arising from consumption of fuel and stores. * [* Reference is made to the Code of Safe Practice for Ships Carrying Timber Deck Cargoes originally adopted by the Organization as resolution A. 287 (VIII) and amended by the Maritime Safety Committee at its thirty-ninth session.] Protection of crew, access to machinery spaces, etc.

(8) In addition to the requirements of Regulation 25 (5), guard-rails or lifelines not more than 350 mm apart vertically shall be provided on each side of the cargo deck to a height of at least 1 m above the cargo.

In addition a lifeline, preferably wire rope set up taut with a stretching screw, shall be provided as near as practicable to the centreline of the ship. The stanchion supports to all guard-rails and lifelines shall be so spaced as to prevent undue sagging. Where the cargo is uneven a safe walking surface of not less than 600 mm in width shall be fitted over the cargo and effectively secured beneath or adjacent to the lifeline.

(9) Where the requirements prescribed in paragraph (8) are impracticable, alternative arrangements satisfactory to the administration shall be used.

Steering arrangements (10) Steering arrangements shall be effectively protected from damage by cargo and, as far as practicable, shall be accessible. Efficient provision shall be made for steering in the event of a breakdown in the main steering arrangements.

Regulation 45 Computation for Freeboard (1) the minimum summer freeboards shall be computed in accordance with Regulation 27 (5), 27 (6), 27 (11), 28, 29, 30, 31, 32, 37 and 38, except that Regulation 37 is modified by substituting the following percentages for those given in Regulation 37: |------------------------ | Total effective length of superstructures | |--------------------| | 0 | 0.1L | 0.2L | 0.3L | 0.4L | 0.5L | 0.6L | 0.7L | 0.8L | 0.9L | 1.0L | |------|---|---|---|---|---|---|---|---|---|---|---| | Percentage of | | | | | | | deduction | | | | | | | for all | 20 | 31 | 42 | 53 | 63 | 70 | 76 | 82 | 88 | 94 | 100 | | types of | | | | | | | superstructures | | | | | | |------------------------ Percentages at intermediate lengths of superstructures shall be obtained by linear interpolation.

(2) The Winter Timber Freeboard shall be obtained by adding to the Summer Timber Freeboard one thirty-sixth of the moulded summer timber draught.

(3) The Winter North Atlantic Timber Freeboard shall be the same as the Winter North Atlantic Freeboard prescribed in Regulation 40 (6).

(4) The Tropical Timber Freeboard shall be obtained by deducting from the Summer Timber Freeboard one forty-eighth of the moulded summer timber draught.

(5) The Fresh Water Timber Freeboard shall be computed in accordance with Regulation 40 (7) based on the summer timber load waterline or with Regulation 40 (8) based on the summer timber draught measured from the top of the keel to the summer timber load line.

Unless secured by closely spaced bolts, the covers shall be permanently attached.

(2) Openings in freeboard decks other than hatchways, machinery space openings, manholes and flush scuttles shall be protected by an enclosed superstructure, or by a deckhouse or companionway of equivalent strength and weathertightness. Any such opening in an exposed superstructure deck or in the top of a deckhouse on the freeboard deck which gives access to a space below the freeboard deck or a space within an enclosed superstructure shall be protected by an efficient deckhouse or companionway. Doorways in such deckhouses or companionways shall be fitted with doors complying with the requirements of Regulation 12 (1).

(3) In position 1 the height above the deck of sills to the doorways in companionways shall be at least 600 millimetres. In position 2 it shall be at least 380 millimetres.

Regulation 19 Ventilators (1) Ventilators in position 1 or 2 to spaces below freeboard decks or decks of enclosed superstructures shall have coamings of steel or other equivalent material, substantially constructed and efficiently connected to the deck. Where the coaming of any ventilator exceeds 900 millimetres in height it shall be specially supported.

(2) Ventilators passing through superstructures other than enclosed superstructures shall have substantially constructed coamings of steel or other equivalent material at the freeboard deck.

(3) Ventilators in position 1 the coamings of which extend to more than 4.5 metres above the deck, and in position 2 the coamings of which extend to more than 2.3 metres above the deck, need not be fitted with closing arrangements unless specifically required by the Administration.

(4) Except as provided in paragraph (3) of this Regulation, ventilator openings shall be provided with efficient weathertight closing appliances.

In ships of not more than 100 metres in length the closing appliances shall be permanently attached; where not so provided in other ships, they shall be conveniently stowed near the ventilators to which they are to be fitted.

Regulation 20 Air Pipes Where air pipes to ballast and other tanks extend above the freeboard or superstructure decks, the exposed parts of the pipes shall be of substantial construction; the height from the deck to the point where water may have access below shall be at least 760 millimetres on the freeboard deck and 450 millimetres on the superstructure deck. Where these heights may interfere with the working of the ship, a lower height may be approved, provided the Administration is satisfied that the closing arrangements and other circumstances justify a lower height. Satisfactory means permanently attached, shall be provided for closing the openings of the air pipes.

Regulation 21 Cargo Ports and Other Similar Openings (1) Cargo ports and other similar openings in the sides of ships below the freeboard deck shall be fitted with doors so designed as to ensure watertightness and structural integrity commensurate with the surrounding shell plating. The number of such openings shall be the minimum compatible with the design and proper working of the ship.

(2) Unless permitted by the Administration, the lower edge of such openings shall not be below a line drawn parallel to the freeboard deck at side, which has at its lowest point the upper edge of the uppermost load line.

Regulation 22 Scuppers, Inlets and Discharges (1) Discharges led through the shell either from spaces below the freeboard deck or from within superstructures and deckhouses on the freeboard deck fitted with doors complying with the requirements of Regulation 12 shall, except as provided in paragraph (2), be fitted with efficient and accessible means for preventing water from passing inboard.

Normally each separate discharge shall have one automatic non-return valve with a positive means of closing it from a position above the freeboard deck. Where, however, the vertical distance from the summer load water line to the inboard end of the discharge pipe exceeds 0.01 L, the discharge may have two automatic non-return valves without positive means of closing, provided that the inboard valve is always accessible for examination under service conditions; where that vertical distance exceeds 0.02 L a single automatic non-return valve without positive means of closing may be accepted subject to the approval of the Administration. The means for operating the positive action valve shall be readily accessible and provided with an indicator showing whether the valve is open or closed.

(2) Scuppers led through the shell from enclosed superstructures used for the carriage of cargo shall be permitted only where the edge of the freeboard deck is not immersed when the ship heels 5¡ã either way. In other cases the drainage shall be led inboard in accordance with the requirements of the International Convention for the Safety of Life at Sea in force.

(3) In manned machinery spaces main and auxiliary sea inlets and discharges in connexion with the operation of machinery may be controlled locally. The controls shall be readily accessible and shall be provided with indicators showing whether the valves are open or closed.

(4) Scuppers and discharge pipes originating at any level and penetrating the shell either more than 450 millimetres below the freeboard deck or less than 600 millimetres above the summer load waterline shall be provided with a non-return valve at the shell. This valve, unless required by paragraph (2), may be omitted if the piping is of substantial thickness.

(5) Scuppers leading from superstructures or deckhouses not fitted with doors complying with the requirements of Regulation 12 shall be led overboard.

(6) All shell fittings, and the valves required by this Regulation shall be of steel, bronze or other approved ductile material. Valves of ordinary cast iron or similar material are not acceptable. All pipes to which this Regulation refers shall be of steel or other equivalent material to the satisfaction of the Administration.

Regulation 23 Side Scuttles (1) Side scuttles to spaces below the freeboard deck or to spaces within enclosed superstructures shall be fitted with efficient hinged inside deadlights arranged so that they can be effectively closed and secured watertight.

(2) No side scuttle shall be fitted in a position so that its sill is below a line drawn parallel to the freeboard deck at side and having its lowest point 2.5 per cent of the breadth (B) above the summer load line (or summer timber load line, if assigned) or 500 millimetres, whichever is the greater distance.

(3) The side scuttles, together with their glasses, if fitted, and deadlights, shall be of substantial and approved construction.

Regulation 24 Freeing Ports (1) Where bulwarks on the weather portions of freeboard or superstructure decks form wells, ample provision shall be made for rapidly freeing the decks of water and for draining them. Except as provided in paragraphs (2) and (3) of this Regulation, the minimum freeing port area (A) on each side of the ship for each well on the freeboard deck shall be that given by the following formulae in cases where the sheer in way of the well is standard or greater than standard. The minimum area for each well on superstructure decks shall be on-half of the area given by the formulae.

Where the length of bulwark (l) in the well is 20 metres or less A = 0.7 + 0.035 l square metres Where l exceeds 20 metres A = 0.07 l square metres l need in no case be taken as greater than 0.7L.

If the bulwark is more than 1.2 metres in average height the required area shall be increased by 0.004 square metres per metre of length of well for each 0.1 metre difference in height. If the bulwark is less than 0.9 metre in average height, the required area may be decreased by 0.004 square metre per metre of length of well for each 0.1 metre difference in height.

(2) In ships with no sheer the area calculated according to paragraph (1) shall be increased by 50 per cent. Where the sheer is less than the standard the percentage shall be obtained by linear interpolation.

(3) Where a ship fitted with a trunk does not comply with the requirements of Regulation 36 (1) (e) or where continuous or substantially continuous hatchway side coamings are fitted between detached superstructures the minimum area of the freeing port openings shall be calculated from the following table: |--------------- | BREADTH OF HATCHWAY OR | AREA OF FREEING PORTS IN | | TRUNK IN RELATION TO | RELATION TO THE TOTAL | | THE BREADTH OF SHIP | AREA OF THE BULWARKS | |------|--------| | | | 40% or less | 20% | | | | 75% or more | 10% | | | |--------------- The area of freeing ports at intermediate breadths shall be obtained by linear interpolation.

(4) In ships having superstructures which are open at either or both ends, adequate provision for freeing the space within such superstructures shall be provided to the satisfaction of the Administration.

(5) The lower edges of the freeing ports shall be as near the deck as practicable. Two-thirds of the freeing port area required shall be provided in the half of the well nearest the lowest point of the sheer curve.

(6) All such openings in the bulwarks shall be protected by rails or bars spaced approximately 230 millimetres apart. If shutters are fitted to freeing ports, ample clearance shall be provided to prevent jamming.

Hinges shall have pins or bearings of non-corrodible material. If shutters are fitted with securing appliances, these appliances shall be of approved construction.

Regulation 25 Protection of the Crew (1) The strength of the deckhouses used for the accommodation of the crew shall be to the satisfaction of the Administration.

(2) Efficient guard rails or bulwarks shall be fitted on all exposed parts of the freeboard and superstructure decks. The height of the bulwarks or guard rails shall be at least 1 metre from the deck, provided that where this height would interfere with the normal operation of the ship, a lesser height may be approved if the Administration is satisfied that adequate protection is provided.

(3) The opening below the lowest course of the guard rails shall not exceed 230 millimetres. The other courses shall be not more than 380 millimetres apart. In the case of ships with rounded gunwales the guard rail supports shall be placed on the flat of the deck.

(4) Satisfactory means (in the form of guard rails, life lines, gangways or underdeck passages, etc.) shall be provided for the protection of the crew in getting to and from their quarters, the machinery space and all other parts used in the necessary work of the ship.

(5) Deck cargo carried on any ship shall be so stowed that any opening which is in way of the cargo and which gives access to and from the crew's quarters, the machinery space and all other parts used in the necessary work of the ship, can be properly closed and secured against the admission of water. Effective protection for the crew in the form of guard rails or life lines shall be provided above the deck cargo if there is no convenient passage on or below the deck of the ship.

Regulation 26 Special Conditions of Assignment for Type `A' Ships Machinery Casings (1) Machinery casings on Type `A' ships as defined in Regulation 27 shall be protected by an enclosed poop or bridge of at least standard height, or by a deckhouse of equal height and equivalent strength, provided that machinery casings may be exposed if there are no openings giving direct access from the freeboard deck to the machinery space. A door complying with the requirements of Regulation 12 may, however, be permitted in the machinery casing, provided that it leads to a space or passageway which is as strongly constructed as the casing and is separated from the stairway to the engine room by a second weathertight door of steel or other equivalent material.

Gangway and Access (2) An efficiently constructed fore and aft permanent gangway of sufficient strength shall be fitted on Type `A' ships at the level of the superstructure deck between the poop and the midship bridge or deckhouse where fitted, or equivalent means of access shall be provided to carry out the purpose of the gangway, such as passages below deck. Elsewhere, and on Type `A' ships without a midship bridge, arrangements to the satisfaction of the Administration shall be provided to safeguard the crew in reaching all parts used in the necessary work of the ship.

(3) Safe and satisfactory access from the gangway level shall be available between separate crew accommodations and also between crew accommodations and the machinery space.

Hatchways (4) Exposed hatchways on the freeboard and forecastle decks or on the tops of expansion trunks on Type `A' ships shall be provided with efficient watertight covers of steel or other equivalent material.

Freeing Arrangements (5) Type `A' ships with bulwarks shall have open rails fitted for at least half the length of the exposed parts of the weather deck or other effective freeing arrangements. The upper edge of the sheer strake shall be kept as low as practicable.

(6) Where superstructures are connected by trunks, open rails shall be fitted for the whole length of the exposed parts of the freeboard deck.

CHAPTER III FREEBOARDS Regulation 27 Types of Ships (1) For the purposes of freeboard computation, ships shall be divided into type `A' and type `B'.

Type `A' Ships (2) A type `A' ship is one which: (a) is designed to carry only liquid cargoes in bulk; (b) has a high integrity of the exposed deck with only small access openings to cargo compartments, closed by watertight gasketed covers of steel or equivalent material; and (c) has low permeability of loaded cargo compartments.

(3) A type `A' ship if over 150 m in length to which a freeboard less than type `B' has been assigned, when loaded in accordance with the requirements of paragraph (11), shall be able to withstand the flooding of any compartment or compartments, with an assumed permeability of 0.95, consequent upon the damage assumptions specified in paragraph (12), and shall remain afloat in a satisfactory condition of equilibrium as specified in paragraph (13). In such a ship the machinery space shall be treated as a floodable compartment, but with a permeability of 0.85.

(4) A type `A' ship shall be assigned a freeboard not less than that based on table A of Regulation 28.

Type `B' Ships (5) All ships which do not come within the provisions regarding type `A' ships in paragraphs (2) and (3) shall be considered as type `B' ships.

(6) Type `B' ships, which in position 1 have hatchways fitted with hatch covers which comply with the requirements of Regulation 15, other than paragraph (7), shall be assigned freeboards based upon the values given in table B of Regulation 28, increased by the values given in the following table: Freeboard increase over tabular freeboard for type `B' ships, for ships with hatch covers not complying with Regulation 15(7) or Regulation 16.

(7) Type `B' ships, which in position 1 have hatchways fitted with hatch covers complying with the requirements of Regulation 15 (7) or Regulation 16, shall, except as provided in paragraphs (8) to (13) inclusive of this regulation, be assigned freeboards based on table B of Regulation 28.

(8) Any type `B' ship of over 100 m in length may be assigned freeboards less than those required under paragraph (7), provided that, in relation to the amount of reduction granted, the Administration is satisfied that: (a) the measures provided for the protection of the crew are adequate; (b) the freeing arrangements are adequate; (c) the covers in positions 1 and 2 comply with the provisions of regulation 16 and have adequate strength, special care being given to their sealing and securing arrangements; and |---------------------- | Length of Freeboard Length of Freeboard Length of Freeboard | | ship increase ship increase ship increase | | (metres) (millimetres) (metres) (millimetres) (metres) (millimetres) | |----------------------| | 108 and below 50 139 175 170 290 | | 109 52 140 181 171 292 | | 110 55 141 186 172 294 | | 111 57 142 191 173 297 | | 112 59 143 196 174 299 | | 113 62 144 201 175 301 | | 114 64 145 206 176 304 | | 115 68 146 210 177 306 | | 116 70 147 215 178 308 | | 117 73 148 219 179 311 | | 118 76 149 224 180 313 | | 119 80 150 228 181 315 | | 120 84 151 232 182 318 | | 121 87 152 236 183 320 | | 122 91 153 240 184 322 | | 123 95 154 244 185 325 | | 124 99 155 247 186 327 | | 125 103 156 251 187 329 | | 126 108 157 254 188 332 | | 127 112 158 258 189 334 | | 128 116 159 261 190 336 | | 129 121 160 264 191 339 | | 130 126 161 267 192 341 | | 131 131 162 270 193 343 | | 132 136 163 273 194 346 | | 133 142 164 275 195 348 | | 134 147 165 278 196 350 | | 135 153 166 280 197 353 | | 136 159 167 283 198 355 | | 137 164 168 285 199 357 | | 138 170 169 287 200 358 | |---------------------- Freeboards at intermediate lengths of ship shall be obtained by linear interpolation. Ships above 200 m in length shall be dealt with by the Administration.

(d) the ship, when loaded in accordance with the requirements of paragraph (11), shall be able to withstand the flooding of any compartment or compartments, with an as summed permeability of 0.95, consequent upon the damage assumptions specified in paragraph (12), and shall remain afloat in a satisfactory condition of equilibrium, as specified in paragraph (13). In such a ship, if over 150 m in length, the machinery space shall be treated as a floodable compartment, but with a permeability of 0.85.

(9) In calculating the freeboards for type `B' ships which comply with the requirements of paragraph (8), (11), (12) and (13), the values from table B of regulation 28 shall not be reduced by more than 60% of the difference between the B and A tabular values for the appropriate ship lengths.

(10) (a) The reduction in tabular freeboard allowed under paragraph (9) may be increased up to the total difference between the values in table A and those in table B of regulation 28 on condition that the ship complies with the requirements of: (i) regulation 26, other than paragraph (4), as if it were a type `A' ship; (ii) paragraph (8), (11) and (13) of this regulation; and (iii) paragraph (12) of this regulation, provided that throughout the length of the ship any one transverse bulkhead will be assumed to be damaged, such that two adjacent fore and aft compartments shall be flooded simultaneously, except that such damage will not apply to the boundary bulkheads of a machinery space.

(b) In such a ship, if over 150 m in length, the machinery space shall be treated as a floodable compartment, but with a permeability of 0.85.

Initial condition of loading (11) The initial condition of loading before flooding shall be determined as follows: (a) The ship is loaded to its summer load waterline on an imaginary even keel.

(b) When calculating the vertical centre of gravity, the following principles apply: (i) Homogeneous cargo is carried.

(ii) All cargo compartments, except those referred to under (iii), but including compartments intended to be partially filled, shall be considered fully loaded except that in the case of fluid cargoes each compartment shall be treated as 98% full.

(iii) If the ship is intended to operate at its summer load waterline with empty compartments, such compartments shall be considered empty provided the height of the centre of gravity so calculated is not less than as calculated under (ii).

(iv) 50% of the individual total capacity of all tanks and spaces fitted to contain consumable liquids and stores is allowed for. It shall be assumed that for each type of liquid, at least one transverse pair or a single centreline tank has maximum free surface, and the tank or combination of tanks to be taken into account shall be those where the effect of free surfaces is the greatest; in each tank the centre of gravity of the contents shall be taken at the centre of volume of the tank. The remaining tanks shall be assumed either completely empty or completely filled, and the distribution of consumable liquids between these tanks shall be effected so as obtain the greatest possible height above the keel for the centre of gravity.

(v) At an angle of heel of not more than 5¡ã in each compartment containing liquids, as prescribed in (ii) except that in the case of compartments containing consumable fluids, as prescribed in (iv), the maximum free surface effect shall be taken into account.

Alternatively, the actual free surface effects may be used, provided the methods of calculation are acceptable to the Administration.

(vi) Weights shall be calculated on the basis of the following values for specific gravities: salt water 1.025 fresh water 1.000 oil fuel 0.950 diesel oil 0.900 lubricating oil 0.900 Damage assumptions (12) The following principles regarding the character of the assumed damage apply: (a) The vertical extent of damage in all cases is assumed to be from the base line upwards without limit.

(b) The transverse extent of damage is equal to B/5 or 11.5 m, whichever is the lesser, measured inboard from the side of the ship perpendicularly to the centreline at the level of the summer load waterline.

(c) If damage of a lesser extent than specified in subparagraphs (a) and (b) results in a more severe condition, such lesser extent shall be assumed.

(d) Except where otherwise required by paragraph (10) (a), the flooding shall be confined to a single compartment between adjacent transverse bulkheads provided the inner longitudinal boundary of the compartment is not in a position within the transverse extent of assumed damage. Transverse boundary bulkheads of wing tanks which do not extent over the full breadth of the ship shall be assumed not to be damaged, provided they extend beyond the transverse extent of assumed damage prescribed in subparagraph (b).

If in a transverse bulkhead there are steps or recesses of not more than 3 m in length located within the transverse extent of assumed damage as defined in subparagraph (b), such transverse bulkhead may be considered intact and the adjacent compartment may be floodable singly. If, however, within the transverse extent of assumed damage there is a step or recess of more than 3 m in length in a transverse bulkhead, the two compartments adjacent to this bulkhead shall be considered as flooded. The step formed by the afterpeak bulkhead and the afterpeak tank top shall not be regarded as a step for the purpose of this regulation.

(e) Where a main transverse bulkhead is located within the transverse extent of assumed damage and is stepped in way of a double bottom or side tank by more than 3 m, the double bottom or side tanks adjacent to the stepped portion of the main transverse bulkhead shall be considered as flooded simultaneously. If this side tank has openings, into one or several holds, such as grain feeding holes, such hold or holds shall be considered as flooded simultaneously. Similarly in a ship designed for the carriage of fluid cargoes, if a side tank has openings into adjacent compartments, such adjacent compartments shall be considered as empty and as being flooded simultaneously. This provision is applicable even when such openings are fitted with closing appliances, except in the case of sluice valves fitted in bulkheads between tanks and where the valves are controlled from the deck. Manhole covers with closely-spaced bolts are considered equivalent to the unpierced bulkhead except in the case of openings in topside tanks making the topside tanks common to the holds.

(f) Where the flooding of any two adjacent fore and compartments is envisaged, main |---| | 2/3 | transverse watertight bulkheads shall be spaced at least |1/3* L | or |---| 14.5m, whichever is the lesser, in order to be considered effective. Where transverse bulkheads are spaced at a lesser distance, one or more of these bulkheads shall be assumed as nonexistent in order to achieve the minimum spacing between bulkheads.

Condition of equilibrium (13) The condition of equilibrium after flooding shall be regarded as satisfactory provided: (a) The final waterline after flooding, taking into account sinkage, heel and trim, is below the lower edge of any opening through which progressive downflooding may take place. Such openings shall include air pipes, ventilators and openings which are closed by means of weathertight doors (even if they comply with Regulation 12) or hatch covers (even if they comply with Regulation 16 or Regulation 19(4)), and may exclude those openings closed by means of manhole covers and flush scuttles (which comply with Regulation 18), cargo hatch covers of the type described in Regulation 27(2), remotely operated sliding watertight doors, and sidescuttles of the non-opening type (which comply with Regulation 23).

However, in the case of doors separating a main machinery space from a steering gear compartment, watertight doors may be of a hinged, quick-acting type kept closed at sea, whilst not in use, provided also that the lower sill of such doors is above the summer load waterline.

(b) If pipes, ducts or tunnels are situated within the assumed extent of damage penetration as defined in paragraph (12) (b), arrangements shall be made so that progressive flooding cannot thereby extend to compartments other than those assumed to be floodable in the calculation for each case of damage.

(c) The angle of heel due to unsymmetrical flooding does not exceed 15¡ã. If no part of the deck is immersed, an angle of heel of up to 17¡ã may be accepted.

(d) The metacentric height in the flooded condition is positive.

(e) When any part of the deck outside the compartment assumed flooded in a particular case of damage is immersed, or in any case where the margin of stability in the flooded condition may be considered doubtful, the residual stability is to be investigated. It may be regarded as sufficient if the righting lever curve has a minimum range of 20¡ãbeyond the position of equilibrium with a maximum righting lever of at least 0.1 m within this range. The area under the righting lever curve within this range shall be not less than 0.0175 m ¡¤rad. The Administration shall give consideration to the potential hazard presented by protected or unprotected openings which may become temporarily immersed within the range of residual stability.

(f) The Administration is satisfied that the stability is sufficient during intermediate stages of flooding.

Ships without means of propulsion (14) A lighter, barge or other ship without independent means of propulsion shall be assigned a freeboard in accordance with the provisions of these regulations. Barges which meet the requirements of paragraphs (2) and (3) may be assigned type `A' freeboards: (a) The Administration should especially consider the stability of barges with cargo on the weather deck. Deck cargo can only be carried on barges to which the ordinary type `B' freeboard is assigned.

(b) However, in the case of barges which are unmanned, the requirements of Regulations 25, 26 (2), 26 (3) and 39 shall not apply.

(c) Such unmanned barges which have on the freeboard deck only small access openings closed by watertight gasketed covers of steel or equivalent material may be assigned a freeboard 25% less than those calculated in accordance with these Regulations.

Regulation 28 Freeboard Tables Type `A' ships (1) The tabular freeboard for Type `A' ships shall be determined from the following table: TABLE A Freeboard Table for Type `A' Ships

Ships above 365 metres in length shall be dealt with by the Administration.

Regulation 29 Correction to the Freeboard for Ships under 100metres in length The tabular freeboard for a Type `B' ship of between 24 metres and 100 metres in length having enclosed superstructures with an effective length of up to 35 per cent of the length of the ship shall be increased by: E 7.5(100-L)(0.35 - --) millimetres L where L = length of ship in metres; E = effective length of superstructure in metres as defined in Regulation 35.

Regulation 30 Correction for Block Coefficient Where the block coefficient (C ) exceeds 0.68, the tabular freeboard b specified in Regulation 28 as modified, if applicable, by Regulations 27 (8), 27 (10) and 29 shall be multiplied |-----| | C + 0.68 | | b | by the factor | ---- | | 1.36 | |-----| Regulation 31 Correction for Depth L L (1) Where D exceeds -- the freeboard shall be increased by (D - --)* 15 15 R millimetres, L where R is --- at lengths less than 120 metres and 250 at 120 metres 0.48 length and above.

L (2) Where D is less than -- no reduction shall be made except in a 15 ship with an enclosed superstructure covering at least 0.6L amidships, with a complete trunk, or combination of detached enclosed superstructures and trunks which extend all fore and aft, where the freeboard shall be reduced at the rate prescribed in paragraph (1) of this Regulation.

(3) Where the height of superstructure or trunk is less than the standard height, the reduction shall be in the ratio of the actual to the standard height as defined in Regulation 33.

Regulation 32 Correction for Position of Deck Line Where the actual depth to the upper edge of the deck line is greater or less than D, the difference between the depths shall be added to or deducted from the freeboard.

Regulation 33 Standard Height of Superstructure The standard height of a superstructure shall be as given in the following table: Standard Height (in metres) |------------------- | L | Raised | All other | | | | (metres) | Quarter Deck | Superstructures | |------|------|------| | 30 or less | 0.90 | 1.80 | | 75 | 1.20 | 1.80 | | 125 or more | 1.80 | 2.30 | |------------------- The standard heights at intermediate lengths of the ship shall be obtained by linear interpolation.

Regulation 34 Length of Superstructure (1) Except as provided in paragraph (2) of this Regulation, the length of a superstructure (S) shall be the mean length of the parts of the superstructure which lie within the length (L).

(2) Where the end bulkhead of an enclosed superstructure extends in a fair convex curve beyond its intersection with the superstructure sides, the length of the superstructure may be increased on the basis of an equivalent plane bulkhead. This increase shall be two-thirds of the fore and aft extent of the curvature. The maximum curvature which may be taken into account in determining this increase is one-half the breadth of the superstructure at the point of intersection of the curved end of the superstructure with its side.

Regulation 35 Effective Length of Superstructure (1) Except as provided for in paragraph (2) of this Regulation, the effective length (E) of an enclosed superstructure of standard height shall be its length.

(2) In all cases where an enclosed superstructure of standard height is set in from the sides of the ship as permitted in Regulation 3 (10), the effective length shall be the length modified by the ratio of b/Bs, where `b' is the breadth of the superstructure at the middle of its length; and `Bs' is the breadth of the ship at the middle of the length of the superstructure. Where a superstructure is set in for a part of its length, this modification shall be applied only to the set in part.

(3) Where the height of an enclosed superstructure is less than the standard height, the effective length shall be its length reduced in the ratio of the actual height to the standard height. Where the height exceeds the standard, no increase shall be made to the effective length of the superstructure.

(4) The effective length of a raised quarter deck, if fitted with an intact front bulkhead, shall be its length up to a maximum of 0.6 L.

Where the bulkhead is not intact, the raised quarter deck shall be treated as a poop of less than standard height.

(5) Superstructures which are not enclosed shall have no effective length.

Regulation 36 Trunks (1) A trunk or similar structure which does not extend to the sides of the ship shall be regarded as efficient on the following conditions: (a) the trunk is at least as strong as a superstructure; (b) the hatchways are in the trunk deck, and the hatchway coamings and covers comply with the requirements of Regulations 13 to 16 inclusive and the width of the trunk deck stringer provides a satisfactory gangway and sufficient lateral stiffness. However, small access openings with watertight covers may be permitted in the freeboard deck; (c) a permanent working platform fore and aft fitted with guard rails is provided by the trunk deck, or by detached trunks connected to superstructures by efficient permanent gangways; (d) ventilators are protected by the trunk, by watertight covers or by other equivalent means; (e) open rails are fitted on the weather parts of the freeboard deck in way of the trunk for at least half their length; (f) the machinery casings are protected by the trunk, by a superstructure of at least standard height, or by a deckhouse of the same height and of equivalent strength; (g) the breadth of the trunk is at least 60 per cent of the breadth of the ship; and (h) where there is no superstructure, the length of the trunk is at least 0.6 L.

(2) The full length of an efficient trunk reduced in the ratio of its mean breadth to B shall be its effective length.

(3) The standard height of a trunk is the standard height of a superstructure other than a raised quarter deck.

(4) Where the height of a trunk is less than the standard height, its effective length shall be reduced in the ratio of the actual to the standard height. Where the height of hatchway coamings on the trunk deck is less than that required under Regulation 15 (1), a reduction from the actual height of trunk shall be made which corresponds to the difference between the actual and the required height of coaming.

Regulation 37 Deduction for Superstructures and Trunks (1) Where the effective length of superstructures and trunks is 1.0 L, the deduction from the freeboard shall be 350 millimetres at 24 metres length of ship, 860 millimetres at 85 metres length, and 1070 millimetres at 122 metres length and above; deductions at intermediate lengths shall be obtained by linear interpolation.

(2) Where the total effective length of superstructures and trunks is less than 1.0 L the deduction shall be a percentage obtained from one of the following tables: Percentage of Deduction for Type `A' Ships |------------------------ | Total effective length of superstructures and trunks | |--------------------| | 0 | 0.1L | 0.2L | 0.3L | 0.4L | 0.5L | 0.6L | 0.7L | 0.8L | 0.9L | 1.0L | |------|---|---|---|---|---|---|---|---|---|---|---| | Percentage | | | | | | | of deduction | | | | | | | for all | 0 | 7 | 14 | 21 | 31 | 41 | 52 | 63 | 75.3 | 87.7 | 100 | | types of | | | | | | | superstructures | | | | | | |------------------------ Percentages at intermediate lengths of superstructures and trunks shall be obtained by linear interpolation.

(3) For ships of Type `B': (a) Where the effective length of a bridge is less than 0.2 L, the percentages shall be obtained by linear interpolation between lines I and II.

(b) Where the effective length of a forecastle is more than 0.4 L, the percentages shall be obtained from line II.

(c) Where the effective length of a forecastle is less than 0.07 L, the above percentages shall be reduced by: (0.07L - f) 5¡Á ---- 0.07L where f is the effective length of the forecastle.

Regulation 38 Sheer General (1) The sheer shall be measured from the deck at side to a line of reference drawn parallel to the keel through the sheer line at amidships.

(2) In ships designed with a rake of keel, the sheer shall be measured in relation to a reference line drawn parallel to the design load waterline.

(3) In flush deck ships and in ships with detached superstructures the sheer shall be measured at the freeboard deck.

(4) In ships with topsides of unusual form in which there is a step or break in the topsides, the sheer shall be considered in relation to the equivalent depth amidships.

(5) In ships with a superstructure of standard height which extends over the whole length of the freeboard deck, the sheer shall be measured at the superstructure deck. Where the height exceeds the standard the least difference (Z) between the actual and standard heights shall be added to each end ordinate. Similarly, the intermediate ordinates at distances of 1/6L and 1/3L from each perpendicular shall be increased by 0.444 Z and 0.111 Z respectively.

(6) Where the deck of an enclosed superstructure has at least the same sheer as the exposed freeboard deck, the sheer of the enclosed portion of the freeboard deck shall not be taken into account.

(7) Where an enclosed poop or forecastle is of standard height with greater sheer than that of the freeboard deck, or is of more than standard height, an addition to the sheer of the freeboard deck shall be made as provided in paragraph (12) of this Regulation.

Standard Sheer Profile (8) The ordinates of the standard sheer profile are given in the following table: Standard Sheer Profile (Where L is in metres) |------------------------- | | Ordinate | | Station | Factor | | | (in millimetres) | |-----|---------|---------|----| | After Perpendicular | L | | | 25 (-- + 10) | 1 | | 1 | 3 | | After half | --L from A. P. | L | | 6 | 11.1 (-- + 10) | 3 | | 1 | 3 | | --L from A. P. | L | | 3 | 2.8 (-- + 10) | 3 | | | 3 | | Amidships | 0 | 1 | |-----|---------|---------|----| | Amidships | 0 | 1 | | 1 | L | | Forward half | --L from F.P. | 5.6 (-- + 10) | 3 | | 3 | 3 | | 1 | L | | --L from F.P. | 22.2 (-- + 10) | 3 | | 6 | 3 | | | L | | Forward Perpendicular | 50 (-- + 10) | 1 | | | 3 | |------------------------- Measurement of Variation from Standard Sheer Profile (9) Where the sheer profile differs from the standard, the four ordinates of each profile in the forward or after half shall be multiplied by the appropriate factors given in the table of ordinates. The difference between the sums of the respective products and those of the standard divided by 8 measures the deficiency or excess of sheer in the forward or after half. The arithmetical mean of the excess or deficiency in the forward and after halves measures the excess or deficiency of sheer.

(10) Where the after half of the sheer profile is greater than the standard and the forward half is less than the standard, no credit shall be allowed for the part in excess and deficiency only shall be measured.

(11) Where the forward half of the sheer profile exceeds the standard, and the after portion of the sheer profile is not less than 75 per cent of the standard, credit shall be allowed for the part in excess; where the after part is less than 50 per cent of the standard no credit shall be given for the excess sheer forward. Where the after sheer is between 50 per cent and 75 per cent of the standard, intermediate allowances may be granted for excess sheer forward.

(12) Where sheer credit is given for a poop or forecastle the following formula shall be used: y L' s = -- -- 3 L Where s = sheer credit, to be deducted from the deficiency or added to the excess of sheer, y = difference between actual and standard height of superstructure at the after or forward perpendicular, L' = mean enclosed length of poop or forecastle up to a maximum length of 0.5 L, L = length of ship as defined in Regulation 3 (1) of this Annex.

The above formula provides a curve in the form of a parabola tangent to the actual sheer curve at the freeboard deck and intersecting the end ordinate at a point below the superstructure deck a distance equal to the standard height of a superstructure. The superstructure deck shall not be less than standard height above this curve at any point. This curve shall be used in determining the sheer profile for forward and after halves of the ship.

Correction for Variations from Standard Sheer Profile (13) The correction for sheer shall be the deficiency or excess of sheer (see paragraphs (9) to (11) inclusive of this Regulation), multiplied by S 0.75 - -- 2L where S is the total length of enclosed superstructures.

Addition for Deficiency in Sheer (14) Where the sheer is less than the standard, the correction for deficiency in sheer (see paragraph (13) of this Regulation) shall be added to the freeboard.

Deduction for Excess Sheer (15) In ships where an enclosed superstructure covers 0.1 L before and 0.1 L abaft amidships, the correction for excess of sheer as calculated under the provisions of paragraph (13) of this Regulation shall be deducted from the freeboard; in ships where no enclosed superstructure covers amidships, no deduction shall be made from the freeboard; where an enclosed superstructure covers less than 0.1 L before and 0.1 L abaft amidships, the deduction shall be obtained by linear interpolation. The maximum deduction for excess sheer shall be at the rate of 125 millimetres per 100 metres of length.

Regulation 39 Minimum Bow Height (1) The bow height defined as the vertical distance at the forward perpendicular between the waterline corresponding to the assigned summer freeboard and the designed trim and the top of the exposed deck at side shall be not less than: for ships below 250 metres in length, |------------| | L 1.36 | | 56L (1 - --) ----millimetres; | | 500 C + 0.68 | | b | |------------| for ships of 250 metres and above in length, |---------| | 1.36 | | 7000 ---- millimetres; | | C + 0.68 | | b | |---------| where L is the length of the ship in metres, |---| | C | is the block coefficient which is to be taken as not less | b | |---| than 0.68.

(2) Where the bow height required in paragraph (3) of this Regulation is obtained by sheer, the sheer shall extend for at least 15 per cent of the length of the ship measured from the forward perpendicular. Where it is obtained by fitting a superstructure, such superstructure shall extend from the stem to a point at least 0.07 L abaft the forward perpendicular, and it shall comply with the following requirements: (a) for ships not over 100 metres in length it shall be enclosed as defined in Regulation 3 (10), and (b) for ships over 100 metres in length it need not comply with Regulation 3 (10) but shall be fitted with closing appliances to the satisfaction of the Administration.

CHAPTER IV SPECIAL REQUIREMENTS FOR SHIPS ASSIGNED TIMBER FREE-BOARDS Regulation 41 Application of this Chapter Regulations 42 to 45 inclusive apply only to ships to which timber load lines are assigned.

Regulation 42 Definitions (1) Timber Deck Cargo The term "timber deck cargo" means a cargo of timber carried on an uncovered part of a freeboard or superstructure deck. The term does not include wood pulp or similar cargo.

(2) Timber Load Line A timber deck cargo may be regarded as giving a ship a certain additional buoyancy and a greater degree of protection against the sea.

For that reason, ships carrying a timber deck cargo may be granted a reduction of freeboard calculated according to the provisions of Regulation 45 and marked on the ship's side in accordance with the provisions of Regulation 6 (3) and (4). However, in order that such special freeboard may be granted and used, the timber deck cargo shall comply with certain conditions which are laid down in Regulation 44, and the ship itself shall also comply with certain conditions relating to its construction which are set out in Regulation 43.

Regulation 43 Construction of Ship Superstructure (1) Ships shall have a forecastle of at least standard height and a length of at least 0.07 L. In addition, if the ship is less than 100 meters in length, a poop of at least standard height, or a raised quarter-deck with either a deckhouse or a strong steel hood of at least the same total height shall be fitted aft.

Double Bottom Tanks (2) Double bottom tanks where fitted within the midship half length of the ship shall have adequate watertight longitudinal sub-division.

Bulwarks (3) The ship shall be fitted either with permanent bulwarks at least 1 metre in height, specially stiffened on the upper edge and supported by strong bulwark stays attached to the deck and provided with necessary freeing ports, or with efficient rails of the same height and of specially strong construction.

The ventilators and air pipes shall be efficiently protected.

(2) Timber deck cargoes shall extend over at least the entire available length which is the total length of the well or wells between superstructures. When there is no limiting superstructure at the after end, the timber shall extend at least to the after end of the aftermost hatchway.

The timber deck cargo shall extend athwartships as close as possible to the ship's side, due allowance being made for obstructions such as guard rails, bulwark stays, uprights, pilot access, etc., provided any gap thus created at the side of the ship shall not exceed a mean of 4% of the breadth. The timber shall be stowed as solidly as possible to at least the standard height of the superstructure other than any raised quarterdeck.

(3) On a ship within a seasonal winter zone in winter, the height of the deck cargo above the weather deck shall not exceed one third of the extreme breadth of the ship.

(4) The timber deck cargo shall be compactly stowed, lashed and secured. It shall not interfere in any way with the navigation and necessary work of the ship.

Uprights (5) Uprights, when required by the nature of the timber, shall be of adequate strength considering the breadth of the ship; the strength of the uprights shall not exceed the strength of the bulwark and the spacing shall be suitable for the length and character of timber carried, but shall not exceed 3 m. Strong angles or metal sockets or equally efficient means shall be provided for securing the uprights.

Lashings (6) Timber deck cargo shall be effectively secured throughout its length by a lashing system acceptable to the Administration for the character of the timber carried*.

[* Reference is made to the Code of Safe Practice for Ships Carrying Timber Deck Cargoes originally adopted by the Organization as resolution A. 287 (VIII) and amended by the Maritime Safety Committee at its thirty-ninth session.] Stability (7) Provision shall be made for a safe margin of stability at all stages of the voyage, regard being given to additions of weight, such as those arising from absorption of water or icing, if applicable, and to losses of weight such as those arising from consumption of fuel and stores. * [* Reference is made to the Code of Safe Practice for Ships Carrying Timber Deck Cargoes originally adopted by the Organization as resolution A. 287 (VIII) and amended by the Maritime Safety Committee at its thirty-ninth session.] Protection of crew, access to machinery spaces, etc.

(8) In addition to the requirements of Regulation 25 (5), guard-rails or lifelines not more than 350 mm apart vertically shall be provided on each side of the cargo deck to a height of at least 1 m above the cargo.

In addition a lifeline, preferably wire rope set up taut with a stretching screw, shall be provided as near as practicable to the centreline of the ship. The stanchion supports to all guard-rails and lifelines shall be so spaced as to prevent undue sagging. Where the cargo is uneven a safe walking surface of not less than 600 mm in width shall be fitted over the cargo and effectively secured beneath or adjacent to the lifeline.

(9) Where the requirements prescribed in paragraph (8) are impracticable, alternative arrangements satisfactory to the administration shall be used.

Steering arrangements (10) Steering arrangements shall be effectively protected from damage by cargo and, as far as practicable, shall be accessible. Efficient provision shall be made for steering in the event of a breakdown in the main steering arrangements.

Regulation 45 Computation for Freeboard (1) the minimum summer freeboards shall be computed in accordance with Regulation 27 (5), 27 (6), 27 (11), 28, 29, 30, 31, 32, 37 and 38, except that Regulation 37 is modified by substituting the following percentages for those given in Regulation 37: |------------------------ | Total effective length of superstructures | |--------------------| | 0 | 0.1L | 0.2L | 0.3L | 0.4L | 0.5L | 0.6L | 0.7L | 0.8L | 0.9L | 1.0L | |------|---|---|---|---|---|---|---|---|---|---|---| | Percentage of | | | | | | | deduction | | | | | | | for all | 20 | 31 | 42 | 53 | 63 | 70 | 76 | 82 | 88 | 94 | 100 | | types of | | | | | | | superstructures | | | | | | |------------------------ Percentages at intermediate lengths of superstructures shall be obtained by linear interpolation.
