    Thales GeoSolutions (Australasia) Ltd successfully completed a deep water multibeam bathymetry survey for BHP Billiton Petroleum Pty Ltd in the Outer Browse Basin offshore northern Western Australia.

    The five-week long campaign began on 01 December 2001 on board the Thales long-term charter vessel Petr Kottsov. The purpose built hydrographic research vessel was fitted with a hull-mounted Simrad EM 12S and EM 1002 multibeam echo sounder, Simrad EA 500single beam system and an on-board GeoAcoustic deep tow Probe 5000 system. The primary positioning used for the campaign was the Thales SkyFix/SkyFix Premier DGPS and Thales MultiFix III Multiple Reference Station positioning software interfacing into the Thales Winfrog navigation system.

    Thales provided a total of 11-specialist crew drawing upon Thales' global pool of experienced personnel. Crew members provided by Thales included the Party Chief, underwater engineers, geophysicists and data processors from the Perth, Aberdeen and Londonoffices.

    The multibeam bathymetry survey is part of BHP Billiton's ongoing petroleum exploration program in the Outer Browse Basin, which is located some 460 km north northwest of Broome. Approximately 10,000sq km of multibeam bathymetry and wavelet data capturewas acquired and processed by Thales during this campaign in water depths ranging between 500m and 3500m.
