Claim:
An offshore system for offloading liquid LNG from a long tanker that lies in a shallow sea, and passing the LNG through equipment that creates warmed gaseous hydrocarbons and passing the warmed hydrocarbons through a gas conduit arrangement to an onshore station comprising: an artificial breakwater device comprising a structure with a lower end fixed to the sea floor and an upper end extending a plurality of meters above the sea surface, said breakwater device having a breakwater length that is at least 60% of the length of said tanker, and having an average width that is no more than 25% of said breakwater length, said breakwater device having opposite breakwater sides spaced by said width; said tanker lying alongside a first of said sides of said breakwater, and moored to said breakwater; regas and pressurizing equipment on said breakwater that heats liquid LNG to turn it into gas and that pressurizes the gas; an offloading conduit that offloads said liquid LNG from said tanker to said breakwater and carries it to said regas and pressurizing equipment; a second conduit that carries gas from said regas and pressurizing equipment to said onshore station.
