Research On The Stowage And Securing Of Steel Coils On Vessels

Recent decades have seen quite few accidents involving damages to both vessels and/or cargoes in the rapid developments of transportation of steel coils by sea in shipping industry. Investigation has shown that the causes of these accidents are as follows: That it is difficult to decide whether the concentrated load criteria or the even load criteria should be used in the assessment of the stowage and securing of coils loaded on board vessels; That due to the fact that certain corrosion and/or damage to the lashing materials are unavoidable, crew members could hardly decide the MSLs for such lashing and securing materials as eye-plates, wires, chains, webs, etc.; That the complexness of assessment for the cargo stowage and securing contained in the revised Code of Safe Practice for the Cargo Stowage and Securing has, to certain extent, prevented its application to the steel coil stowage on board vessels; That quite a lot of crew members are, in a practical view, lack of necessary knowledge for the indentification of various damages to the steel coils done prior to shipment, during the transport and even after the carriage.With a view to further enhance the safety of the carriage of steel coils by sea, researches have been made in this paper with following achievements:1. A new method for the determination of load criterion has, based on the payable load of a hold, been developed for the assessment of the stowage and securing of steel coils on board vessels, which is between the concentrated load and the even load on the deck;2. In accordance with the prevailing regulations, rules, codes, usages and practices promulgated or published by international maritime institutions, shipping companies, class societies and maritime authorities, a series of...
