WATER INTAKE UNIT OF PIPELINES FOR OFFSHORE STRUCTURE AND METHOD FOR PRODUCTION OF LIQUEFIED HYDROCARBON FLOW AND METHOD OF FLOW OF GASEOUS HYDROCARBONS Russian patent published in 2016 - IPC F25J1/00 B63B35/44 

FIELD: pipe.

SUBSTANCE: group of inventions relates to pipelines water-intake unit, which can be suspended to marine structure. Unit includes beam from first tubular channel and second tubular channel, which essentially extend side by side in direction of length. Each contains nearest section, containing suspension, further connection section, further remote section containing water intake section. Said remote section extends between first remote edge and connecting area of corresponding tubular channel. Said connection section connecting by fluid nearest and remote section. At that, first and second transverse tubular channels are interconnected by means of one spacer sleeve in combination with appropriate connection sections of suspended part of remote section of first tubular channel extends farther toward length than second tubular channel. Invention also describes methods for production of liquefied hydrocarbon flow and method of producing stream of gaseous hydrocarbons.

EFFECT: group of inventions enables reducing risk of complete termination of transportation of water in nearest section due to plugging in remote part of water intake unit of pipelines.
