Research On The Stowage And Securing Of Container Crane On Heavylift Carriers

Recent decades have seen the rapid development of transportation of container cranes by sea in shipping industry, which benefited from persistent growth of container transportation volume. However, disasters or accidents involved in their transportation atrract more and more attention from both academic institutions and shipping companies.Investigation has shown that the causes of these accidents are as flollows: That the insufficient preparation for container cranes prior to shipment leads to the fact that the structural strength and stability of cranes themselves can't bear the external loads during voyages; That the improper planning of the securing arrangements for meeting the requirements of the circumustances at sea; That the inaccurate assessment or overestimation of the securing equipment without approved strength; and That the incorrect calculation and prediction of the loads which will be subjected to by the container crane loaded on board during the voyage.With a view to further enhance the safety of the transportation of container cranes by sea, researches have been made in this thesis with following achievements: Several preparation proceedings have, based on transportation cases already completed, been summarized; A disertation on the design of securing arrangements has been made in details in combination of a case of container crane transportation in Nanjing; In accordance with the prevailing regulations, rules, codes, usages and practices promulgated or published by international maritime institutions, shipping companies, class societies and maritime autorities, a series of formulas for the determination of maximum safe working load for lashing and...
