SYSTEMS AND METHODS FOR UNDERWATER NOISE REDUCTION Russian patent published in 2016 - IPC E02B17/02 G10K11/16 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions is referred to marine systems and methods for development of offshore oil and gas fields. The marine system in the basin comprises a drill unit at the basin surface, a drilling bit in a well at the basin bottom, the area with sensitive environment at distance from the well, and multitude of floating flexible constructions deployed between the well and the area with sensitive environment, at that the floating flexible constructions are flat hoses mounted in uninflated rolled position and further they are inflated and erected into vertical position. The method for development of offshore oil and gas field includes mounting of a drill unit in basin, drilling multitude of wells by the above drill unit and placing multitude of the floating flexible constructions close to the well, at that the floating flexible constructions are flat hoses mounted in uninflated rolled position and further they are inflated and erected into vertical position.

EFFECT: reduced noise pollution of underwater environment and reduced impact on marine flora and fauna.
