criteria in paragraph (b) of Regulation 4 of this Chapter (see Figure 1), the ship's stability calculations shall be normally based upon the assumption that the centre of gravity of cargo in a "filled compartment" is at the volumetric centre of the whole cargo space. In those cases where the Administration authorizes account to be taken of the effect of assumed underdeck voids on the vertical position of the centre of gravity of the cargo in "filled compartments" it will be necessary to compensate for the adverse effect of the vertical shift of grain surfaces by increasing the assumed heeling moment due to the transverse shift of grain as follows: total heeling moment=1.06 ¡Ácalculated transverse heeling moment.

In all cases the weight of cargo in a "filled compartment" shall be the volume of the whole cargo space divided by the stowage factor.

(d) In "partly filled compartments" the adverse effect of the vertical shift of grain surfaces shall be taken into account as follows: total heeling moment=1.12 ¡Ácalculated transverse heeling moment.

(e) Any other equally effective method may be adopted to make the compensation required in paragraphs (c) and (d) above. Figure 1 Notes on Figure 1: (1) Where: |--| Assumed Volumetric Heeling Moment due to Transverse Shift | ¦Ë |= --------------- | 0| |--| Stowage Factor ¡ÁDisplacement |---|--| | ¦Ë |= 0.8¡Á |¦Ë | ; | 40| 0 | |---|--| Stowage factor = Volume per unit weight of grain cargo; Displacement = Weight of ship, fuel, fresh water, stores etc. and cargo.

(2) The righting arm curve shall be derived from cross-curves which are sufficient in number to accurately define the curve for the purpose of these requirements and shall include cross-curves at 12 degrees and 40 degrees.

SECTION II-ASSUMED VOLUMETRIC HEELING MOMENT OF A FILLED COMPART-MENT (A) General (a) The pattern of grain surface movement relates to a transverse section across the portion of the compartment being considered and the resultant heeling moment should be multiplied by the length to obtain the total moment for that portion.

(b) The assumed transverse heeling moment due to grain shifting is a consequence of final changes of shape and position of voids after grain has moved from the high side to the low side.

(c) The resulting grain surface after shifting shall be assumed to be at 15 degrees to the horizontal.

(d) In calculating the maximum void area that can be formed against a longitudinal structural member, the effects of any horizontal surfaces, e.g. flanges or face bars, shall be ignored.

(e) The total areas of the initial and final voids shall be equal.

(f) A discontinuous longitudinal division shall be considered effective over its full length.

(B) Assumptions In the following paragraphs it is assumed that the total heeling moment for a compartment is obtained by adding the results of separate considerations of the following portions: (a) Before and abaft hatchways: (i) If a compartment has two or more main hatchways through which loading may take place the depth of the underdeck void for the portion (s) between such hatchways shall be determined using the fore and aft distance to the midpoint between the hatchways.

(ii) After the assumed shift of grain the final void pattern shall be as shown in Figure 2 below: Figure 2 Notes on Figure 2: (1) If the maximum void area which can be formed against the girder at B is less than the initial area of the void under AB, i.e. AB¡ÁVd, the excess area shall be assumed to transfer to the final void on the high side.

(2) If the longitudinal division at C is one which has been provided in accordance with sub-paragraph (b) (ii) of Regulation 5 of this Chapter it shall extend to at least 0.6 metre below D or E whichever gives the greater depth.

(b) In and abreast hatchways: After the assumed shift of grain the final void pattern shall be as shown in the following Figure 3 or figure 4. Figure 3 Notes on Figure 3: (1) AB Any area in excess of that which can be formed against the girder at B shall transfer to the final void area in the hatchway.

(2) CD Any area in excess of that which can be formed against the girder at E shall transfer to the final void area on the high side.

Figure 4: ommited.

Notes on Figure 4: (1) If the centreline division is one which has been provided in accordance with sub-paragraph (b) (ii) of Regulation 5 of this Chapter it shall extend to at least 0.6 metre below H or J whichever gives the greater depth.

(2) The excess void area from AB shall transfer to the low side half of the hatchway in which two separate final void areas will be formed viz.

one against the centreline division and the other against the hatchside coaming and girder on the high side.

(3) If a bagged saucer or bulk bundle is formed in a hatchway it shall be assumed, for the purpose of calculating transverse heeling moment, that such a device is at least equivalent to the centreline division.

(C) Compartments Loaded in Combination The following paragraphs describe the pattern of void behaviour which shall be assumed when compartments are loaded in combination: (a) Without effective centreline divisions: (i) Under the upper deck-as for the single deck arrangement described in Section II (B) of this Part.

(ii) Under the second deck-the area of void available for transfer from the low side, i.e. original void area less area against the hatchside girder, shall be assumed to transfer as follows: one half to the upper deck hatchway and one quarter each to the high side under the upper and second deck.

(iii) Under the third and lower decks-the void areas available for transfer from the low side of each of these decks shall be assumed to transfer in equal quantities to all the voids under the decks on the high side and the void in the upper deck hatchway.

(b) With effective centreline divisions which extend into the upper deck hatchway: (i) At all deck levels abreast the division the void areas available for transfer from the low side shall be assumed to transfer to the void under the low side half of the upper deck hatchway.

(ii) At the deck level immediately below the bottom of the division the void area available for transfer from the low side shall be assumed to transfer as follows: one half to the void under the low side half of the upper deck hatchway and the remainder in equal quantities to the voids under the decks on the high side.

(iii) At deck levels lower than those described in sub-paragraphs (i) and (ii) of this paragraph the void area available for transfer from the low side of each of those decks shall be assumed to transfer in equal quantities to the voids in each of the two halves of the upper deck hatchway on each side of the division and the voids under the decks on the high side.

(c) With effective centreline divisions which do not extend into the upper deck hatchway: Since no horizontal transfer of voids may be assumed to take place at the same deck level as the division the void area available for transfer from the low side at this level shall be assumed to transfer above the division to voids on the high sides in accordance with the principles of paragraphs (a) and (b) above.

SECTION III-ASSUMED VOLUMETRIC HEELING MOMENT OF FEEDERS ANDTRUNKS (A) Suitably Placed Wing Feeders (See Figure 5) It may be assumed that under the influence of ship motion underdeck voids will substantially filled by the flow of grain from a pair of longitudinal feeders provided that: (a) the feeders extend for the full length of the deck and that the perforations therein are adequately spaced; (b) the volume of each feeder is equal to the volume of the underdeck void outboard of the hatchside girder and its continuation. Figure 5 (B) Trunks Situated over Main Hatchways After the assumed shift of grain the final void pattern shall be as shown in Figure 6. Figure 6 Note on Figure 6: If the wing spaces in way of the trunk cannot be properly trimmed in accordance with Regulation 3 of this Chapter it shall be assumed that a 25 degree surface shift takes place.

SECTION IV-ASSUMED VOLUMETRIC HEELING MOMENT OF PARTLY FILLED COM-PARTMENTS (A) General When the free surface of the bulk grain has not been secured in accordance with Regulation 6 of this Chapter it shall be assumed that the grain surface after shifting shall be at 25 degrees to the horizontal.

(B) Discontinuous Longitudinal Divisions In a compartment in which the longitudinal divisions are not continuous between the transverse boundaries, the length over which any such divisions are effective as devices to prevent full width shifts of grain surfaces shall be taken to be the actual length of the portion of the division under consideration less two-sevenths of the greater of the transverse distances between the division and its adjacent division or ship's side.

This correction does not apply in the lower compartments of any combination loading in which the upper compartment is either a "filled compartment" or a "partly filled compartment".

SECTION V-ALTERNATIVE LOADING ARRANGEMENTS FOR EXISTING SHIPS (A) General A ship loaded in accordance with either Sub-Section (B) of Sub-Section (C) below shall be considered to have intact stability characteristics at least equivalent to the requirements of paragraph (b) of Regulation 4 of this Chapter. Documents of authorization permitting such loadings shall be accepted under the provisions of paragraph (e) of Regulation 10 of this Chapter.

For the purpose of this Part, the term "Existing Ship" means a ship, the keel of which is laid before the date of coming into force of this Chapter.

(B) Stowage of Specially Suitable Ships (a) Notwithstanding anything contained in Part B of this Chapter, bulk grain may be carried without regard to the requirements specified therein in ships which are constructed with two or more vertical or sloping grain-tight longitudinal divisions suitably disposed to limit the effect of any transverse shift of grain under the following conditions: (i) as many holds and compartments as possible shall be full and trimmed full; (ii) for any specified arrangement of stowage the ship will not list to an angle greater than 5 degrees at any stage of the voyage where: (1) in holds or compartments which have been trimmed full the grain surface settled 2 per cent by volume from the original surface and shifts to an angle of 12 degrees with that surface under all boundaries of these holds and compartments which have an inclination of less than 30 degrees to the horizontal; (2) in "partly filled compartments or holds" free grain surfaces settle and shift as in sub-paragraph (ii) (1) of this paragraph or to such larger angle as may be deemed necessary by the Administration, or by a Contracting Government on behalf of the Administration, and grain surfaces if overstowed in accordance with Regulation 5 of this Chapter shift to an angle of 8 degrees with the original levelled surfaces. For the purpose of sub-paragraph (ii) of this paragraph shifting boards, if fitted, will be considered to limit the transverse shift of the surface of the grain; (iii) the master is provided with a grain loading plan covering the stowage arrangements to be adopted and a stability booklet, both approved by the Administration, or by a Contracting Government on behalf of the Administration, showing the stability conditions upon which the calculations given in sub-paragraph (ii) of this paragraph are based.

(b) The Administration, or a Contracting Government on behalf of the Administration, shall prescribe the precautions to be taken against shifting in all other conditions of loading of ships designed in accordance with paragraph (B) (a) of this Section which meet the requirements of sub-paragraphs (ii) and (iii) of that paragraph.

(C) Ships Without Documents of Authorization A ship not having on board documents of authorization issued in accordance with Regulations 4 and 10 of this Chapter may be permitted to load bulk grain under the requirements of Sub-Section (B) of this Section or provided that: (a) All "filled compartments" shall be fitted with centreline divisions extending for the full length of such compartments which extend downwards from the underside of the deck or hatch covers to a distance below the deck line of at least one-eighth of the maximum breadth of the compartment or 2.4 metres, whichever is the greater except that saucers constructed in accordance with Section II of Part C may be accepted in lieu of a centreline division in and beneath a hatchway.

(b) All hatches to "filled compartments" shall be closed and covers secured in place.

(c) All free grain surfaces in "partly filled compartments" shall be trimmed level and secured in accordance with Section II of Part C.

(d) Throughout the voyage the metacentric height after correction for the free surface effects of liquids in tanks shall be 0.3 metre or that given by the following formula, whichever is the greater: |---------| | | | LBVd(0.25B-0.645 ¡ÌVdB | | GM =------ | | R | | SF¡Á¡÷¡Á0.0875 | |---------| Where: L= total combined length of all full compartments; B= moulded breadth of vessel; SF= stowage factor; Vd= calculated average void depth as per paragraph (a) (i) of Section I (A) of this Part; ¡÷= displacement.

PART C GRAIN FITTINGS AND SECURING
SECTION I-STRENGTH OF GRAIN FITTINGS (A) General (a) Timber All timber used for grain fittings shall be of good sound quality and of a type and grade which has been proved to be satisfactory for this purpose. The actual finished dimensions of the timber shall be in accordance with the dimensions hereinafter specified in this Part. Plywood of an exterior type bonded with waterproof glue and fitted so that the direction of the grain in the face plies is perpendicular to the supporting uprights or binder may be used provided that its strength is equivalent to that of solid timber of the appropriate scantlings.

(b) Working Stresses When calculating the dimensions of divisions loaded on one side, using the Tables in paragraph (a) and (b) of Sub-Section (C) of this Section, the following working stresses should be adopted: For divisions of steel ................ 2000 kg per square cm For divisions of wood .................. 160 kg per square cm (c) Other Materials Materials other than wood or steel may be approved for such divisions provided that proper regard has been paid to their mechanical properties.

(d) Uprights (i) Unless means are provided to prevent the ends of uprights being dislodged from their sockets, the depth of housing at each end of each upright shall be not less than 75 mm. If an upright is not secured at the top, the uppermost shore or stay shall be fitted as near thereto as is practicable.

(ii) The arrangements provided for inserting shifting boards by removing a part of the cross-section of an upright shall be such that the local level of stresses is not unduly high.

(iii) The maximum bending moment imposed upon an upright supporting a division loaded on one side shall normally be calculated assuming that the ends of the up-rights are freely supported. However, if an Administration is satisfied that any degree of fixity assumed will be achieved in practice, account may be taken of any reduction in the maximum bending moment arising from any degree of fixity provided at the ends of the upright.

(e) Composite Section Where uprights, binders or any other strength members are formed by two separate sections, one fitted on each side of a division and inter-connected by through bolts at adequate spacing, the effective section modules shall be taken as the sum of the two modules of the separate sections.

(f) Partial Division Where divisions do not extend to the full depth of the hold such divisions and their up-rights shall be supported or stayed so as to be as efficient as those which do extend to the full depth of the hold.

(B) Divisions Loaded on Both Sides (a) Shifting Boards (i) Shifting boards shall have a thickness of not less than 50 mm and shall be fitted grain-tight and where necessary supported by uprights.

(ii) The maximum unsupported span for shifting boards of various thicknesses shall be as follows: Thickness Maximum Unsupported Span 50mm 2.5metres 60mm 3.0metres 70mm 3.5metres 80mm 4.0metres If thicknesses greater than these are provided the maximum unsupported span will vary directly with the increase in thickness.

(iii) The ends of all shifting boards shall be securely housed with 75 mm minimum bearing length.

(b) Other Materials Divisions formed by using materials other than wood shall have a strength equivalent to the shifting boards required in paragraph (a) of this Sub-Section.

(c) Uprights (i) Steel uprights used to support divisions loaded on both sides shall have a section modulus given by |-----| | W=a¡ÁW | | 1 | |-----| Where: W=section modulus in cubic cm ; a= horizontal span between uprights in metres.

|-| The section modulus per metre span|W | shall be not less than that | 1| |-| given by the formula: |----------| | W =14.8(h -1.2)cubic cm per metre;| | 1 1 | |----------| Where: h is the vertical unsupported span in metres and shall be taken as the maximum 1 value of the distance between any two adjacent stays or between the stay or either end of the upright. Where this distance is less than 2.4 metres the respective modulus shall be calculated as if the actual value was 2.4 metres.

(ii) The module of wood uprights shall be determined by multiplying by 12.5 the corresponding module for steel uprights. If other materials are used their module shall be at least that required for steel increased in proportion to the ratio of the permissible stresses for steel to that of the material used. In such cases attention shall be paid also to the relative rigidity of each upright to ensure that the deflection is not excessive.

(iii) The horizontal distance between uprights shall be such that the unsupported spans of the shifting boards do not exceed the maximum span specified in sub-paragraph (ii) of paragraph (a) of this Sub-Section.

(d) Shores (i) Wood shores, when used, shall be in a single piece and shall be securely fixed at each end and heeled against the permanent structure of the ship except that they shall not bear directly against the side plating of the ship.

(ii) Subject to the provisions of sub-paragraphs (iii) and (iv) below, the minimum size of wood shores shall be as follows: Length of Shore Rectangular Diameter of in metres Section Circular Section mm mm Not exceeding 3 m 150 ¡Á100 140 Over 3 m but not exceeding 5 m 150 ¡Á150 165 Over 5 m but not exceeding 6 m 150 ¡Á150 180 Over 6 m but not exceeding 7 m 200 ¡Á150 190 Over 7 m but not exceeding 8 m 200 ¡Á150 200 Exceeding 8 m 200 ¡Á150 215 Shores of 7 metres or more in length shall be securely bridged at approximately mid-length.

(iii) When the horizontal distance between the uprights differs significantly from 4 metres, the moments of inertia of the shores may be changed in direct proportion.

(iv) Where the angle of the shore to the horizontal exceeds 10 degrees the next larger shore to that required by sub-paragraph (ii) of this paragraph shall be fitted provided that in no case shall the angle between any shore and the horizontal exceed 45 degrees.

(e) Stays Where stays are used to support divisions loaded on both sides, they shall be fitted horizontally or as near thereto as practicable, well secured at each end and formed of steel wire rope. The sizes of the wire rope shall be determined assuming that the divisions and upright 2 which the stay supports are uniformly loaded at 500 kg/m . The workings load so assumed in the stay shall not exceed one-third of its breaking load.

(C) Divisions Loaded on One Side Only (a) Longitudinal Divisions The load in kg per metre length of the division shall be taken to be as follows: TABLE I* [* For the purpose of converting the above loads into British units (ton/ft) 1 Kg per metre length shall be taken to be equivalent to 0.0003 ton per foot length.] TABLE I* B (m) |---------------------- |h | 2 3 4 5 6 7 8 10 |(m) |---------------------- | 1.5 850 900 1010 1225 1500 1770 2060 2645 | 2.0 1390 1505 1710 1985 2295 2605 2930 3590 | 2.5 1985 2160 2430 2740 3090 3435 3800 4535 | 3.0 2615 2845 3150 3500 3885 4270 4670 5480 | 3.5 3245 3525 3870 4255 4680 5100 5540 6425 | 4.0 3890 4210 4590 5015 5475 5935 6410 7370 | 4.5 4535 4890 5310 5770 6270 6765 7280 8315 | 5.0 5185 5570 6030 6530 7065 7600 8150 9260 | 6.0 6475 6935 7470 8045 8655 9265 9890 11150 | 7.0 7765 8300 8910 9560 10245 10930 11630 13040 | 8.0 9055 9665 10350 11075 11835 12595 13370 14930 | 9.0 10345 11030 11790 12590 13425 14260 15110 16820 |10.0 11635 12395 13230 14105 15015 15925 16850 18710 | h= height of grain in metres from the bottom of the division * | B= transverse extent of the bulk grain in metres |---------------------- [* where the distance from a division to a feeder or hatchway is 1 metre or less, the height -h- shall be taken to the level of the grain within that hatchway or feeder. In all cases the height shall be taken to the overhead deck in way of the division.] For other values of h or B the loads shall be determined by linear interpolation or extrapolation as necessary.

(b) Transverse Divisions The load in kg per metre length of the division shall be taken to be as follows: TABLE II** [** For the purpose of converting the above loads into British units (ton/ft) 1 Kg per metre length shall be taken to be equivalent to 0.0003 ton per foot length.] TABLE II* L (m) |------------------------------ |h | 2 3 4 5 6 7 8 10 12 14 16 |(m) |------------------------------ | 1.5 670 690 730 780 835 890 935 1000 1040 1050 1050 | 2.0 1040 1100 1170 1245 1325 1400 1470 1575 1640 1660 1660 | 2.5 1460 1565 1675 1780 1880 1980 2075 2210 2285 2305 2305 | 3.0 1925 2065 2205 2340 2470 2590 2695 2845 2925 2950 2950 | 3.5 2425 2605 2770 2930 3075 3205 3320 3480 3570 3595 3595 | 4.0 2950 3160 3355 3535 3690 3830 3950 4120 4210 4235 4240 | 4.5 3495 3725 3940 4130 4295 4440 4565 4750 4850 4880 4885 | 5.0 4050 4305 4535 4735 4910 5060 5190 5385 5490 5525 5530 | 6.0 5175 5465 5720 5945 6135 6300 6445 6655 6775 6815 6825 | 7.0 6300 6620 6905 7150 7365 7445 7700 7930 8055 8105 8115 | 8.0 7425 7780 8090 8360 8590 8685 8950 9200 9340 9395 9410 | 9.0 8550 8935 9275 9565 9820 9930 10205 10475 10620 10685 10705 |10.0 9680 10095 10460 10770 11045 11270 11460 11745 11905 11975 11997 | h= height of grain in metres from the bottom of the division *** | L= longitudinal extent of the bulk grain in metres |------------------------------ [*** Where the distance from a division to a feeder or hatchway is 1 metre or less, the height -h- shall be taken to the level of the grain within that hatchway or feeder.

(c) Vertical Distribution of the Loads The total load per unit length of divisions shown in the Table I and II above may, if considered necessary, be assumed to have a trapezoidal distribution with height. In such cases, the reaction loads at the upper and lower ends of a vertical member or upright are not equal. The reaction loads at the upper end expressed as percentages of the total load supported by the vertical member or upright shall be taken to those shown in Tables III and IV below.

The strength of the end connexions of such vertical members or uprights may be calculated on the basis of the maximum load likely to be imposed at either end. These loads are as follows: Longitudinal Divisions Maximum load at the top .........50% of the appropriate total load from Table I Maximum load at the bottom ......55% of the appropriate total load from Table I Transverse Divisions Maximum load at the top.......45% of the appropriate total load from Table II Maximum load at the bottom....60% of the appropriate total load from Table II The thickness of horizontal wooden boards may also be determined having regard to the vertical distribution of the loading represented by Tables III and IV above and in such cases
t=10a¡Ì p¡Ák --- h ¡Á213.3 Where: t= thickness of board in mm; a= horizontal span of the board, i.e. distance between uprights in metres; h= head of grain to the bottom of the division in metres; p= total load per unit length derived from Table I or II in kilogrammes; k= factor dependent upon vertical distribution of the loading; When the vertical distribution of the loading is assumed to be uniform, i.e. rectangular, k shall be taken as equal to 1.0. For a trapezoidal distribution k=1.0+0.06(50-R) Where: R is the upper end bearing reaction taken from Table III or IV.

(d) Stays of Shores The sizes of stays and shores shall be so determined that the loads derived from Tables I and II in the preceding paragraphs (a) and (b) shall not exceed one-third of the breaking loads.

(D) Saucers When a saucer is used to reduce the heeling moments in a "filled compartment", its depth, measured from the bottom of the saucer to the deck line, shall be as follows: For ships with a moulded breadth of up to 9.1 metres, not less than 1.2 metres.

For ships with a moulded breadth of 18.3 metres or more, not less than 1.8 metres.

For ships with a moulded breadth between 9.1 metres and 18.3 metres, the minimum depth of the saucer shall be calculated by interpolation.

The top (mouth) of the saucer shall be formed by the underdeck structure in the way of the hatchway, i.e. hatchside girders or coamings and hatchend beams. The saucer and hatchway above shall be completely filled with bagged grain or other suitable cargo laid down on a separation cloth or its equivalent and stowed tightly against adjacent structures and the portable hatchway beams if the latter are in place.

(E) Bundling of Bulk As an alternative to filling the saucer with bagged grain or other suitable cargo a bundle of bulk grain may be used provided that: (a) The saucer is lined with a material acceptable to the Administration having a tensile strength of not less than 274 kg per 5 cm strip and which is provided with suitable means for securing at the top.

(b) As an alternative to paragraph (a) above a material acceptable to the Administration having a tensile strength of not less than 137 kg per 5 cm strip may be used if the saucer is constructed as follows: A thwartship lashings acceptable to the Administration shall be placed inside the saucer formed in the bulk grain at intervals of not more than 2.4 metres. These lashings shall be of sufficient length to permit being drawn up tight and secured at the top of the saucer.

Dunnage not less than 25 mm in thickness or other suitable material of equal strength and between 150 to 300 mm in width shall be placed fore and aft over these lashings to prevent the cutting or chafing of the material which shall be placed thereon to line the saucer.

(c) The saucer shall be filled with bulk grain and secured at the top except that when using material approved under paragraph (b) above further dunnage shall be laid on top after lapping the material before the saucer is secured by setting up the lashings.

(d) If more than one sheet of material is used to line the saucer they shall be joined at the bottom either by sewing or a double lap.

(e) The top of the saucer shall be coincidental with the bottom of the beams when these are in place and suitable general cargo or bulk grain may be placed between the beams on top of the saucer.

(F) Securing Hatch Covers of Filled Compartments If there is no bulk grain or other cargo above a "filled compartment" the hatch covers shall be secured in an approved manner having regard to the weight and permanent arrangements provided for securing such covers.

The documents of authorization issued under Regulation 10 of this Chapter shall include reference to the manner of securing considered necessary by the Administration issuing such documents.

SECTION II-SECURING OF PARTLY FILLED COMPARTMENTS (A) Strapping or Lashing (a) When, in order to eliminate heeling moments in "partly filled compartments", strapping or lashing is utilized, the securing shall be accomplished as follows: (i) The grain shall be trimmed and levelled to the extent that it is very slightly crowned and covered with burlap separation cloths, tarpaulins or the equivalent.

(ii) The separation cloths and/or tarpaulins shall overlap at least 1.8 metres.

(iii) Two solid floors of rough 25 mm by 150 mm to 300 mm lumber shall be laid with the top floor running longitudinally and nailed to an athwartships bottom floor. Alternatively, one solid floor of 50 mm lumber, running longitudinally and nailed over the top of a 50 mm bottom bearer not less than 150 mm wide, may be used. The bottom bearers shall extend the full breadth of the compartment and shall be spaced not more than 2.4 metres apart. Arrangements utilizing other materials and deemed by an Administration to be equivalent to the foregoing may be accepted.

(iv) Steel wire rope (19 mm diameter or equivalent), doubled steel strapping (50mm¡Á1.3 mm and having a breaking load of at least 5000 kg), or chain of equivalent strength, each of which shall be set tight by means of a 32 mm turnbuckle, may be used for lashings. A winch tightener, used in conjunction with a locking arm, may be substituted for the 32 mm turnbuckle when steel strapping is used, provided suitable wrenches are available for setting up as necessary. When steel strapping is used, not less than three crimp seals shall be used for securing the ends. When wire is used, not less than four clips shall be used for forming eyes in the lashings.

(v) Prior to the completion of loading the lashing shall be positively attached to the framing at a point approximately 450 mm below the anticipated final grain surface by means of either a 25 mm shackle or beam clamp of equivalent strength.

(vi) The lashings shall be spaced not more than 2.4 metres apart and each shall be supported by a bearer nailed over the top of the fore and all floor. This bearer shall consist of not less than 25 mm by 150 mm lumber or its equivalent and shall extend the full breadth of the compartment.

(vii) During the voyage the strapping shall be regularly inspected and set up where necessary.

(B) Overstowing Arrangements Where bagged grain or other suitable cargo is utilized for the purpose of securing "partly filled compartments", the free grain surface shall be covered with a separation cloth or equivalent or by a suitable platform.

Such platforms shall consist of bearers spaced not more than 1.2 metres apart and 25 mm boards laid thereon spaced not more than 100 mm apart.

Platforms may be constructed of other materials provided they are deemed by an Administration to be equivalent.

(C) Bagged Grain Bagged grain shall be carried in sound bags which shall be well filled and securely closed.
