LNGLPGfartyg

LNGLPGfartyg is a maritime designation used to describe ships designed and equipped to transport liquefied natural gas (LNG) and liquefied petroleum gas (LPG) in bulk. The term covers vessels with specialized cryogenic cargo containment systems and handling gear required to keep these gases at very low temperatures during transit.

Designs and configurations vary. LNG carriers commonly use spherical Moss tanks or membrane systems, while LPG carriers may employ spherical or cylindrical tanks. Some LNGLPGfartyg are designed to carry LNG and LPG in segregated tanks, enabling carriage of different gases on the same voyage, though most vessels are dedicated to a single cargo type. Tank arrangements, insulation, and boil-off management are tailored to the specific gas and cargo pressure requirements.

Safety and operation. Cargo is maintained at cryogenic temperatures; boil-off gas is managed through venting or reliquefaction systems. Ships include complex gas detection, emergency shutdown systems, inert gas installations, and highly insulated cargo spaces. Regulations specify construction, equipment, and operation under the International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code), SOLAS rules, and MARPOL environmental standards, with oversight by classification societies.

Commercial role. LNGLPGfartyg support long-distance energy trades, moving LNG and LPG from production regions to consuming markets. They operate in specialized port facilities with cryogenic handling capabilities and require highly trained crews to manage the technical and safety demands of cryogenic cargoes.
