These CCS Rules have been developed on the basis of the technical requirements outlines in the IGC Code, which was adopted by IMO MSC by Res. MSC.5(48) and amendments. The authors of the publication aimed it primarily for the vessels carrying liquefied gases and built in full compliance with the Chinese Class Society conditions of classification.
The complete text of the above mentioned IGC Code have been incorporated in the present CCS Rules together with the amendments and some additional paragraphs and interpretations. In case the vessel in question has not been authorized to be issued with the COF, i.e. Certificate of Fitness, all Rules and Flag Administration requirements must be complied with. As declared, the ultimate goal of this document was to provide people with the necessary technical info relating to the classification surveys during the construction and the operation of the ships carrying liquefied gases. The technical requirements that have been included in this rulebook will be of some interest for the crew members and owners of the ships classed with the other Societies, as well.
The Rules contain general provisions, classification and surveys, approval of relevant plans/documents of vessels, additional requirements applicable to the ship hull structures, etc.
