Scope: This standard specifies the structural type, requirements, test methods, inspection rules, marking, packaging, transportation and storage of semi-cooled and semi-pressurized liquefied gas storage tanks (hereinafter referred to as storage tanks) for liquefied gas carriers. This standard is applicable to liquefied gas transport ships with a design vapor pressure of not more than 0.8 MPa, a design temperature of -165°C ~ -10°C, and storage media for liquefied natural gas (LNG), liquefied petroleum gas (LPG), ethylene, and vinyl chloride (VCM). ), liquid ammonia and other liquefied gases, and the design, manufacture and acceptance of C-type independent storage tanks installed inside the cargo hold of the ship hull. This standard also applies to the design, manufacture and acceptance of C-type independent storage tanks (hereinafter referred to as deck tanks) installed on open-air decks for liquefied gas transport ships with a design vapor pressure of not more than 2.0 MPa and a design temperature of -165°C ~ 45°C. .
