Passage 2-01
The objective of lashing the coils is to form one large, immovable block of units in the hold by lashing them together.
In general, strip coils in three end rows in the top tier should be lashed. To prevent fore-and-aft shifting in the top tier of bare-wound coils group-lashing should not be applied due to their fragile nature; the end row of a top tier should be secured by dunnage and wires, which are to be tightened from side to side, and by additional wires to the bulkhead. When coils are fulry loaded over the entire bottom space and are well shored, no lashings are required except for locking coils,
The lashings can be of a conventional type using wire steel band or any equivalent means. Conventional lashings should consist of wires having sufficient tensile strength. The first tier should be chocked. It should be possible to re-tighten the lashings during the voyage. Wire lashings should be protected against damage from sharp edges.
If there are few coils, or a single coil only, they should be adequately secured to the ship, by placing them in cradles, by wedging, or by shoring and then lashing to prevent transverse and longitudinal movement.
