ClassNK amends rules for construction of ships carrying liquefied gases

Japan’s classification society ClassNK amended its Rules and Guidance for the survey and construction of steel ships as a response to the latest industry developments. 

New rules are additionally a response to the amendments made to the international code for the construction and equipment of ships carrying liquefied gases in bulk, ClassNK said in a statement.

IMO decided to carry out the first full review of the IGC Code to reflect the latest technological advancements and increasing ship size.

ClassNK amendments will apply to ships carrying liquefied gases in bulk whose keels are laid, or which are at a similar stage of construction on or after July 1, 2016.

The classification society has also made amendments to requirements related to the non-destructive testing for machinery installations, application forms for the approval and type approval of materials and equipment for marine use, portable atmosphere testing instruments for enclosed spaces and approval of diesel engines.
