CONSTRUCTION OF SEA TERMINALS FOR EXTRACTION OF UNDERWATER HYDROCARBON ACCUMULATION

摘要

FIELD: mining.;SUBSTANCE: claimed method consists in erection of some sea stationary platforms, sea bottom complexes, underwater in-field and main pipelines, well products stores and unloading plants. Note here that at least one of said platforms is an underwater version with thrust unit secured to the sea bottom, thrust unit top gage being located below water level by the maximum clearance of iceberg underwater part gage. Note also that all underwater platforms are structurally and functionally connected by electric cables and condensate and gas pipelines. Regular seismic sounding is performed in the area of terminals by passive sounding of sea bottom and analysis of microseismic vibrations of the earth crust.;EFFECT: higher reliability of construction and operation.
