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 Foxs sister ship, Kalvik, had been delivered by Victoria shipyard in July of the same year. At the time, Beaudril's two icebreakers were the most powerful privately owned icebreaking vessels in the world. Design General characteristics Terry Fox is long overall and between perpendiculars. She has a beam of and draws 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 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 cargo hold in place of the original bulk cargo tanks. Power and propulsion Terry Fox has a diesel-mechanical propulsion system consisting of four main engines driving two shafts through twin input-single output gearboxes. The prime movers are eight-cylinder Stork-Werkspoor 8TM410 medium-speed diesel engines producing at 600rpm in continuous service. Each pair of main engines is 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. However, each propeller shaft is also fitted with a heavy flywheel in diameter and in thickness to increase rotational inertia and absorb shocks from propeller-ice interaction. Unlike the other Canadian offshore icebreakers built in the 1980s, Terry Fox does not have a propeller nozzles to shroud her propellers. Her LIPS Canada
