Multibeam echo sounders have been providing SHOM, the French Hydrographic Office, with high resolution, high accuracy acoustic readings to construct navigational safety maps for more than 20 years. After 10 years of reliable service, their current multibeam echo sounder systems are being upgraded by EurOceanique with modern acoustic mapping systems.
The first of the 3 vessels to upgrade is Laperouse, which was built in 1980 and has been using the Kongsberg EM1002 multibeam echo sounder system. The modern EM710 system will be installed on Laperouse in July 2011 and tested in September 2011.
EurOceanique, part of the MacArtney Group and exclusive Kongsberg representative in France for hydrographic products, will also supply system updates for sister ships Borda and Laplace in 2013 and 2014.
