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 ofa 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 ofa 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 l ashings should be protected against damage from sharp edges. If there are few coils, ora 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. O01 . The locking coil is ______ coil secured by shorings coil placed in cradle coil used to secure other coils coil secured by wedgings 002 . The general objective of lashing coils is to prevent them from _______ A. transverse and longitudinal movement B. rolling in the hold C. vertical movement D. fore-and-aft shifting 003 . When coils are fully loaded over tank top and are well shored, _________ A. three end rows in the top tier should be lashed B. no lashings are required except for locking coils C. they should be secured to the ship by wedging D. they should be placed in cradles 004 . If there isa single coil, its securing should be done by _________ A. placing it in cradle and then lashing it B. shoring it and then placing it in cradle C. placing it in cradle, wedging it, shori
