CCGS Terry Fox
CCGS Terry Fox is a Canadian Coast Guard heavy icebreaker. She was originally built by Burrard-Yarrows Corporation in Canada in 1983 as part of an Arctic drilling system developed by BeauDril, the drilling subsidiary of Gulf Canada Resources. After the offshore oil exploration in the Beaufort Sea ended in the early 1990s, she was first leased and then sold to the Canadian Coast Guard.
Terry Fox's sister ship, Kalvik, is today owned by the Russian Murmansk Shipping Company as Vladimir Ignatyuk.
In the mid-1970s, Gulf Canada Resources began developing an Arctic drilling system consisting of two mobile drilling units: a Mobile Arctic Caisson (MAC) that could be submerged and filled with gravel to form an artificial drilling island in waters up to 40 metres (130 ft) in depth and a floating Conical Drilling Unit (CDU) designed for drilling in water depths between 40 and 60 metres (130 and 200 ft) while afloat. The intention of this development was to overcome the relatively short operating window of drillships during the ice-free season (100 to 110 days a year) and the water depth limitations of artificial dredged islands in the Canadian part of the Beaufort Sea. The drilling units, each capable of completing one exploration well per year, would be supported by four Arctic Class 4 vessels: two large icebreakers providing 24-hour ice management and standby services on the drilling site and two smaller icebreaking vessels responsible for anchor handling and supply runs between the drilling rigs and coastal bases. By 1982, both drilling units and all four icebreaking vessels were under construction in Canada and Japan for BeauDril, Gulf Canada's drilling subsidiary, and the company had committed itself to a billion-dollar exploration program between 1983 and 1988.
The icebreaker design was provided by the Montreal-based engineering company German & Milne. During the development phase, the hull form was extensively tested at the Hamburg Ship Model Basin (HSVA) ice tank with particular emphasis of preventing broken ice floes from flowing under the hull and into the propellers. The result was a production-friendly fully-developable hull form with a semi-spoon bow and large ice plough. The construction of the two icebreakers was awarded to Burrard-Yarrows Corporation in December 1979 and the work was split between the company's Victoria and Vancouver divisions. In order to expedite the delivery of the vessels, Gulf Canada had already purchased the engines, gearboxes, shaft lines and propellers before signing the C$79 million shipbuilding contract for two hulls.
The keel of newbuilding number 107 was laid at the Burrard-Yarrows Vancouver shipyard on 15 June 1982 and the vessel was launched on 23 April 1983 as Terry Fox. While the other BeauDril icebreakers and drilling units were given names drawn from the Northern Territories native languages, Terry Fox was named after Terrance Stanley "Terry" Fox (1958–1981), a Canadian athlete, humanitarian and cancer research activist known for his 1980 Marathon for Hope, an attempted cross-Canada run to raise money and awareness for cancer research, after losing his right leg to osteosarcoma. The icebreaker was completed on 16 September 1983, slightly behind the original schedule which called for delivery in April when Gulf Canada's exploratory drilling program was set to begin. Terry Fox's sister ship, Kalvik, had been delivered by Victoria shipyard in July of the same year. At the time, Beaudril's two 23,200 hp (17,300 kW) icebreakers were the most powerful privately owned icebreaking vessels in the world.
Terry Fox is 88 metres (289 ft) long overall and 75 metres (246 ft) between perpendiculars. She has a beam of 17.82 metres (58 ft) and draws 8.3 metres (27 ft) of water when fully laden.
While the crew's common spaces such as mess rooms and lounges are arranged on the main deck, the accommodation is arranged in the box-shaped deckhouse. In the Canadian Coast Guard service, Terry Fox has a complement of 10 officers and 14 crew, and 10 additional berths. The towing gear consists of an 80-ton winch holding 1,500 metres (1,600 yd) of wire and a separate 200-ton double-drum anchor-handling winch. Unlike her sister ship, Terry Fox has not been retrofitted with a helideck. However, her cargo-handling capability has been increased with a 40-tonne cargo crane and a 490 m3 (17,000 cu ft) cargo hold in place of the original bulk cargo tanks.
Terry Fox has a diesel-mechanical propulsion system consisting of four main engines driving two shafts through twin input-single output gearboxes. As built, the ship was fitted with eight-cylinder Stork-Werkspoor 8TM410 medium-speed diesel engines producing 5,800 hp (4,300 kW) at 600 rpm in continuous service. The engines were coupled to a Lohmann & Stolterfoht Navilus GVE 1500 A single-stage reduction gearbox via flexible couplings designed to automatically disengage if the propellers are blocked by ice. During the drivetrain refit, the original main engines were replaced with eight-cylinder Bergen B33:45L8P medium-speed engines. The original gearboxes were replaced as well.
