IGC CODE 2016 eDition ixForewordat its forty-eighth session (June 1983), the maritime Safety Committee (mSC) of the international maritime organization (imo) adopted amendments to the Internat

41、ional Maritime Convention for the Safety of Life at Sea, 1974 (SoLaS), by resolution mSC.6(48).the amendments consisted of complete replacement texts of chapters iii and Vii and changes in chapters ii-1, ii-2 and iV.the new chapter Vii made the provisions of the International Code for the Constructi

42、on and Equipment of Ships Carrying Liquefied Gases in Bulk (igC Code), which was adopted by resolution mSC.5(48), mandatory under the 1974 SoLaS Convention.the new 2016 edition of the igC Code incorporates the amendments adopted by the mSC at its ninety-third session (may 2014) by resolution mSC.370

43、(93). these amendments, which entered into force on 1 January 2016, consist of a complete replacement text of the igC Code. Unless expressly provided otherwise, the requirements of the igC Code, as amended by resolution mSC.370(93), apply to ships whose keels are laid, or which are at a similar stag

44、e of construction, on or after 1 July 2016. For ships constructed on or after 1 July 1986 and before 1 July 2016, unless expressly provided otherwise, the administration shall ensure that such ships comply with the requirements which are applicable under the igC Code, as adopted by resolution mSC.5(

45、48) and as amended by resolutions mSC.17(58), mSC.30(61), mSC.32(63), mSC.59(67), mSC.103(73), mSC.177(79) and mSC.220(82). Licensed to IHS Markit by IMO. IMO. All rights reserved.
