The LNG storage tank uses half film prismatic LNG maintenance system of plate, and the plate refers to its inside cabin tank by shape
The regular aluminum of shape or steel plateform are welded, and half film refers to that the secondary shielding of its containment system only needs portion envelops without being finished
Full package inside cabin tank, prismatic refer to that the containment system monnolithic case is similar to prismatic polygon column structure for regular,
The containment system has the advantages that volume is big, weight is lighter, the influence to external structure is smaller.
For the liquid goods pipeline that the other function platform expansible with upstream and downstream is connect, for LNG storage platform and other
The connection of function platform, the loading platform of such as LNG, for the loading and unloading of tank inside LNG, distribution platform is used for down
Swim natural gas distribution, as gas or liquid it is canned, sell, gasify platform, is used for gasification of liquid LNG, natural toward downstream conveying
Gas, it is industrial or it is civilian be ok, liquefaction skid, BOG's is re-liquefied, reduces the loss of LNG, generation platform, with gas LNG
Power generation etc. can be actually needed according to upstream and downstream and carry out multi-functional extension.
The technical effect of the utility model is as follows:
It 1, is a kind of work in waters, foundation structure is using the achievable LNG storage of fixed platform and its derivation function
