POLLUTION MONITORING AND DETECTION SYSTEM FOR OFFSHORE OIL AND GAS FIELDS Russian patent published in 2014 - IPC G01S17/00 

FIELD: oil and gas industry.

SUBSTANCE: system includes a network of fluorescent lidars installed at oil and gas producing platforms, tankers transporting oil and vessels servicing the field; a network of automatic floating and monitoring complexes (MC) installed at the distance from the remote the oil and gas producing platform, and each complex comprises water-contacting sensors for registration of hydrocarbons, physical and chemical and hydrologic parameters of water and a submerged water-tight buoy placed, in particularly, under ice and containing a programmable controller with systems for acquisition, preliminary processing and transmission of data generated by the MC sensors; as well as a united automated information system (IS) with functions for acquisition, processing and storage of data generated by lidars and floating MCs. In the preferred embodiments the MC includes a fluorescent lidar placed in a submerged buoy having in the upper part a window transparent for probe and backscattered radiation.

EFFECT: development of a reliable system for early detection and monitoring of emergency oil spills at facilities of the offshore oil and gas field, including complicated conditions of in the Arctic region.
