CCGS Des Groseilliers instance of icebreaker
Operational history
The third vessel in the class, Des Groseilliers was ordered in December 1979 as part of the Canadian government's efforts to stimulate shipbuilding in Canada. The ship was constructed by Port Weller Dry Docks at their shipyard in Port Weller, Ontario with the yard number 68 and was launched on 20 February 1982. The vessel was commissioned in August 1982 and completed in October. The ship replaced the aging icebreaker CCGS D'Iberville in the Laurentian Region. The vessel is registered in Ottawa, Ontario and homeported at Quebec City, Quebec. During the winter, Des Groseilliers is assigned to icebreaking and ship escort operations in the Gulf of St. Lawrence and on the St. Lawrence and Saguenay Rivers and supports icebreaking operations in the Saint Lawrence Seaway and Great Lakes. During the summer the icebreaker sails to the Canadian Arctic to escort commercial vessels, maintain navigation aids in the region, search and rescue, and support scientific missions.In 1983, Des Groseilliers made her first voyage to the Arctic. In April 1984, after the opening of the navigation season on the Saint Lawrence Seaway and the Great Lakes, the area froze up, driving six cargo ships ashore and a further eighteen became stuck in the ice. Five icebreakers were assigned to aid the merchant vessels, however, they proved unable to meet the task. Des Groseilliers and CCGS Griffon were sent to their aid, with Des Groseilliers arriving on 11 April and worked to free the stuck vessels and provide safe passage until 29 April. The following year, the icebreaker escorted the icebreaking cargo ship Arctic to Cameron Island in the Arctic to load 100,000 barrels of oil.
