CCGS Louis S. St-Laurent alongside USCGC Healy
Baird Maritime reports Quebec shipbuilder Chantier Davie Canada has been awarded a contract to complete a service life extension program on Canada’s largest, most powerful, and oldest icebreaker, CCGS Louis S St-Laurent.
This ship entered service in 1969, about six and a half years earlier than Polar Star. Reportedly the modifications will be conducted in three phases in 2022,2024, and 2027.
The Canadian Coast Guard rates the ship a heavy icebreaker, but by current USCG standards, she is a medium icebreaker. Her size, power (27,000 HP), diesel electric propulsion, and large lab spaces, make her more similar to Healy than to the Polar Star.
The ship has already been extensively modified. In a major refit 1987-1992 the hull was lengthened about 24 feet. A new bow was fitted and her original steam turbines were replaced with diesels. A bubbler system was added and a new hangar forward of the flight deck replaced the previous below deck hangar and elevator system.
The ship has a crew of only 46 but accommodations for 216.
In 2008, a program was initiated to replace the St-Laurent with a 2017 expected in service date for the new icebreaker. After a series of delays and false starts new Polar Icebreakers are not now expected until 2030 (at least).
I wonder if perhaps the Canadian Coast Guard will attempt to keep the St-Laurent in service until their second polar icebreaker is completed, much as the USCG intends to keep Polar Star in service until the second Polar Security Cutter is delivered.
