An apparatus, system and method for capture, utilization and sendout of latent heat in boil off gas (“BOG”) onboard a cryogenic storage vessel is described. A liquefied gas vessel comprises a cryogenic cargo tank onboard a liquefied gas vessel, the cargo tank comprising a liquefied gas and a BOG, a latent heat exchanger fluidly coupled to a stream of the liquefied gas and a stream of the BOG, wherein the latent heat exchanger transfers a heat between the BOG stream and the liquefied gas stream to produce a condensed BOG, means for combining the condensed BOG and the liquefied gas stream to obtain a combined stream, the means for combining the condensed BOG and the liquefied gas stream fluidly coupled to the latent heat exchanger, and a liquefied gas regasifier onboard the vessel and fluidly coupled to the combined stream, wherein the liquefied gas regasifier regasifies the combined stream.

A sealed and thermally insulative tank includes thermal installation including a plurality of juxtaposed insulation blocks on the supporting structure and a seal including a plurality of sealing metal plates disposed on the insulation blocks and welded to each other. Mechanical coupling members extend through the thermal insulation at the level of the edges of the insulation blocks and hold the insulation blocks in bearing engagement on the supporting structure. The metal plates are disposed so that the edges of the metal plates are offset relative to the edges of the underlying insulation blocks. The metal plates are held in bearing engagement on the insulation blocks only by the coupling members. The mechanical coupling members are attached to the metal plates at the level of attachment points away from the edges of the metal plates.
摘要:
A support installed at sea in grounded or floating manner, the support including both a processor installation on its deck for processing a first liquid that is dangerous and/or corrosive, preferably liquefied natural gas (LNG), and also at least one tank for storing said first liquid, preferably an LNG tank incorporated within the hull of the support under the deck. The support includes at least one container situated outside the support and situated at least in part, and preferably completely, below the deck of the support on which said installation is supported, the container being fastened to the support, preferably in reversible manner, the deck including or supporting a first transfer mechanism suitable for transferring towards the container any leakage liquid flowing from at least a portion of the installation, in particular in the event of a leak.

摘要:
An economical system provides gaseous hydrocarbon to numerous locations (16, 18) that are each in the vicinity of an ocean coast, such as islands in a developing country, so the coastal inhabitants have access to low cost, easily supplied by pipeline and clean-burning natural gas. The system includes a local supply station (24), or hub, that stores natural gas, as by receiving LNG (liquefied natural gas) that has been liquefied by cooling it to −160° C., from a large tanker (20) having a storage capacity of over 50 million standard cubic feet of natural gas. Shuttle boats (40) that each has a much smaller LNG storage capacity than the tanker, load LNG from the local supply station, carry it to one of a plurality of local coastal stations (12, 14), heat the LNG to produce gaseous hydrocarbons, and transfer the gaseous hydrocarbons to an offshore receiving facility of the local coastal station. The gaseous hydrocarbons are then used by the local coastal station as to distribute gaseous hydrocarbons to residents of the island or to fuel an electricity generating plant.
摘要:
In apparatus to convert cryogenic fluid to gas, a vaporizer having passages to pass the cool or cold cryogenic fluid in heat transfer relation with warming gas flowing downwardly through the vaporizer, the vaporizer having surfaces on which ice collects and from which ice falls to the base of the vaporizer and collects in a pile, and removing fluid flow control means operating to direct flow of removing fluid at the ice pile with sufficient force to cause removal of such ice in the pile relative to the vaporizer base.
摘要:
An independent vessel tank system for storing liquid gas on a vessel has a first tank member, a second, cylindrical tank member connected to the first tank member, a third tank member connected to the second tank member, wherein the first, second and third tank members provide a tank device for the liquid gas, a first supporting device provided between the third tank member and a hull of the vessel, for supporting the weight of the tank device, and a second supporting device at least partially provided along a periphery of the tank device, for supporting the tank device to the hull of the vessel. The second supporting device is flexible in a first direction parallel to the centre axis of the tank device, and flexible in a second direction perpendicular to the periphery of the tank device.
