✨ Marine Safety Regulations
Oct. 12.] THE NEW ZEALAND GAZETTE. 3267
Rule LXXXVIII.—Uprights.
Uprights when required by the nature of the timber are to be of adequate strength and may be of wood or metal; the spacing is to be suitable for the length and character of timber carried, but is not to exceed 10 feet. Strong angles or metal sockets efficiently secured to the stringer plate or equally efficient means are to be provided for securing the uprights.
Rule LXXXIX.—Lashings.
Timber deck cargo is to be efficiently secured throughout its length by independently overall lashings spaced not more than 10 feet apart. Eye plates for these lashings are to be riveted to the sheerstrake at intervals of not more than 10 feet, the distance from an end bulkhead of a superstructure to the first eye plate being not more than 6 feet 6 inches. Additional eye plates may be fitted on the stringer plate.
Overall lashings are to be in good condition and are to be not less than ¾ inch close link chain or flexible wire rope of equivalent strength, fitted with sliphooks and stretching screws, which are to be accessible at all times. Wire rope lashings are to have a short length of long link chain to permit the length of lashings to be regulated.
When timber is in lengths less than 12 feet, the spacing of the lashings is to be reduced to suit the length of timber or other suitable provision made.
When the spacing of the lashings is 5 feet or less, the size of the lashing may be reduced, but not less than ½ inch chain or equivalent wire rope is to be used.
All fittings required for securing the lashings are to be of strength corresponding to the strength of the lashings.
On superstructure decks, uprights, where fitted, are to be about 10 feet apart and are to be secured by athwartship lashings of ample strength.
Rule XC.—Plans.
Plans showing the fittings and arrangements for stowing and securing timber deck cargoes in compliance with the foregoing conditions and regulations are to be submitted to the Assigning Authority.
Freeboard.
Rule XCI.—Computation of Freeboard.
Where the Assigning Authority is satisfied that the ship is suitable and that the conditions and arrangements are at least equal to the foregoing requirements for the carriage of timber deck cargo, the Summer freeboards computed in accordance with the Rules and Tables in Part III may be modified to give special timber freeboards, by substituting the following percentages for those in Rule LIII:—
TOTAL Effective Length of Superstructures.
| — | 0 | 0·1 L | 0·2 L | 0·3 L | 0·4 L | 0·5 L | 0·6 L | 0·7 L | 0·8 L | 0·9 L | 1·0 L |
|---|---|---|---|---|---|---|---|---|---|---|---|
| All types | Per Cent. 20 | Per Cent. 30·75 | Per Cent. 41·5 | Per Cent. 52·25 | Per Cent. 63 | Per Cent. 69·25 | Per Cent. 75·5 | Per Cent. 81·5 | Per Cent. 87·5 | Per Cent. 93·75 | Per Cent. 100 |
The Winter Timber freeboard is to be obtained by adding to the Summer Timber freeboard one-third of an inch per foot of the moulded Summer Timber draught.
The Winter North Atlantic Timber freeboards are the Winter North Atlantic freeboards prescribed in Rule LXV.
The Tropical Timber freeboard is to be obtained by deducting from the Summer Timber freeboard one-quarter of an inch per foot of the moulded Summer Timber draught.
