CCS RULES FOR NATURAL GAS FUELLED SHIPS

The Rules are considered applicable to the steel vessels having the gas fuel engines installed and also having a length of not less than twenty meters. They do not apply to the passenger vessels and carriers of the dangerous cargoes. Note that the natural gas fuelled vessels shall also comply with the requirements of the CCS Rules for the Classification of Steel Sea-Going Ships, as applicable.

In addition to that, due attention shall be paid to all relevant requirements of the Administration, if any. The vessels to which these Rules apply may be powered by either single- or dual fuel. The natural gas is commonly stored in liquid or gaseous form.

The content of the document is arranged in several chapters covering all important aspects including general provisions and associated documentations and plans, location on spaces on board ships and their separation, air locks and accesses, design of shipboard systems and piping arrangements, supply of the gas fuel, storage of the gaseous fuels - containment systems, portable tanks, storage of the fuel on the open deck and in the enclosed- and semi-enclosed spaces, bunkering, ventilation, fire safety arrangements, training and operation requirements, and many other issues.
