This International Standard specifies the requirements for ship, terminal and port service providers to ensure the safe transit of an liquefied natural gas carrier (LNGC) through the port area and the safe and efficient transfer of its cargo. It is applicable to a) pilotage and vessel traffic services (VTS); b) tug and mooring boat operators; c) terminal operators; d) ship operators; e) suppliers of bunkers, lubricants and stores and other providers of services whilst the LNG carrier is moored alongside the terminal. This International Standard includes provisions for - a ship's safe transit, berthing, mooring and unberthing at the jetty; - cargo transfer; - access from jetty to ship; - operational communications between ship and shore; - all instrumentation, data and electrical connections used across the interface, including OPS (cold ironing), where applicable; - the liquid nitrogen connection (where fitted); - ballast water considerations. This International Standard applies only to conventional onshore liquefied natural gas (LNG) terminals and to the handling of LNGC's in international trade. However, it can provide guidance for offshore and coastal operations.
