Korean Register: helping with development of super-large container liners

摘要

Work by the Korean Register of Shipping (KR) on the highly topical subject of next-generation LNG carriers was detailed in our special September supplement, Design and Operation of Gas Carriers; however, this classification society is working equally hard in other directions to ensure the technical safety of new and existing ships. In particular, studies are continuing into super-large container liners up to around 12,000TEU. Such sizes represent the boundary where twin shaftlines will probably come into play and where wakefield characteristics need to be carefully studied (although it is possible that 14-cylinder low-speed diesel engines, mooted by at least one of the two leading manufacturers, may alter this scenario). Although no outcome has yet been determined by the society, it has developed tools for analysis of alignment and vibration of propulsion shafting for both single-and twin-screw variants.
