The Canadian Coast Guard has chosen Kongsberg Maritime to provide high resolution EM 712 multibeam echo sounders to the Canadian Coast Guard’s medium icebreakers, CCGS Pierre Radisson and the CCGS Des Groseilliers.
Gathering critical hydrographic data can be a challenge in the Canadian Arctic.
The retractable design of the new EM 712 echo sounder systems optimizes performance of the sounder when deployed and protects it when the vessel is breaking ice, Kongsberg explained.
When deployed, the high-resolution EM 712 collects valuable navigational and scientific data and is capable of mapping a swath of the seabed up to 3,000 meters wide in 3,600 meters of water.
CCGS Pierre Radisson is the lead ship of its class of icebreakers. Constructed and operated by the Canadian Coast Guard, the vessel based at Quebec City, was constructed in British Columbia in the 1970s and has been in service ever since.
The second vessel, CCGS Des Groseilliers, is a Pierre Radisson-class icebreaker in the Canadian Coast Guard. The vessel entered service in 1982.
