PROCEDURE FOR CONSTRUCTION OF DEEP WATER SEA OIL AND GAS DEPOSITS Russian patent published in 2010 - IPC E02B17/00 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to development of underwater deposits of minerals, mainly fluid and gaseous, particularly to construction of process complexes designed for equipping deep water sea oil and gas deposits and operating under extreme conditions. The method of construction of deep water sea oil and gas deposits consists in building a row of sea stationary platforms, underwater bottom complexes, underwater intra-field pipelines and mains, and tanks of well product storage and shipping installations; also at least one of the platforms is made in underwater modification with a bearing block secured to sea bottom; upper dimension of the block is arranged below water level at value of utmost dimension of underwater part of iceberg passing. In addition, all platforms in underwater modification are structurally and technologically connected between them with electric cables and pipelines for condensate and gas.

EFFECT: ugraded reliability of construction and operation, reduced capital and operational expenditures at construction of deep water oil and gas deposits.
