CCGS Sir Humphrey Gilbert
CCGS Sir Humphrey Gilbert is a former Canadian Coast Guard light icebreaker and buoy tender that was later sold to a private owner and renamed Polar Prince. The ship entered service with the Department of Transport Marine Service in 1959 and transferred to the newly created Canadian Coast Guard in 1962, active until 2001. The icebreaker was sold to private interests in Newfoundland and renamed Polar Prince, sitting mostly idle until resold in 2009 to GTX Technology Canada Limited for service in the Arctic Ocean as a commercial icebreaker. In 2017, the vessel was temporarily rechristened Canada C3 and used for a high-profile voyage around Canada's three maritime coasts as part of the nation's 150th anniversary. In November 2021, the ship was purchased by Miawpukek Horizon Maritime Service Ltd, a joint venture between Horizon Maritime and the Miawpukek First Nation and chartered for educational and research expedition use.
Description
The icebreaker is long overall with a beam of and a draught of. The ship has a fully loaded displacement of and a gross register tonnage (GRT) of 2,153 and as built. The vessel is powered by diesel-electric engines driving two shafts turning fixed-pitch propellers creating. This gives the vessel a maximum speed of. The vessel can carry of diesel fuel and had a range of at and could stay at sea for up to 30 days. The vessel was remeasured as with a in 1985.Construction and career
Design and construction
The icebreaker was constructed by Davie Shipbuilding at their yard in Lauzon, Quebec, with the yard number 614. The ship was launched on 29 October 1958 and named after Humphrey Gilbert, an early explorer of the Northwest Passage. Sir Humphrey Gilbert was based on the proven design of the icebreakers CCGS Montcalm and CCGS Wolfe, but updated with diesel electric engines.Government service
Sir Humphrey Gilbert was commissioned into the Department of Transport's Marine Service in June 1959. In 1962, all Marine Service icebreakers were transferred to the newly formed Canadian Coast Guard. The vessel was registered in Ottawa, Ontario and based for most of her career in Newfoundland and Labrador with a homeport at Newfoundland and Labrador|St. John's].On 20 December 1963, the French vessel Douala transmitted a distress signal off the coast of Newfoundland. Sir Humphrey Gilbert had already been detailed to aid a fishing vessel in the Atlantic, but was redirected to Douala as the French ship was in danger of foundering. While heading to Douala a barge broke loose aboard the Coast Guard vessel, causing damage to the ship and it was some time before the barge could be secured due to icing conditions. The Coast Guard vessel was delayed in arriving on the scene by the barge and on 21 December, Douala sank. 19 crew members of Douala were rescued on 22 December, of which two died while returning to Newfoundland. 13 members of the crew died in the water.
In 1983, Sir Humphrey Gilbert became the test vessel for the Coast Guard's lay day crewing system. Under the lay day system, each ship has two crews which rotate on a 28-day interval. While on board the ship, the crew perform 12-hour work shifts, seven days a week. At the end of the 28-day interval, the crew rotates off the ship for a four-week break. The trials proved a success and the system was adopted fleet-wide.
Sir Humphrey Gilbert received a mid-life refit at the Halifax Shipyard in 1984 which significantly changed the ship. Her original bow was cut off and replaced with a new one with an air bubbler system to reduce friction when breaking ice. This added to the ship's length. The bridge wings were enclosed and a large new derrick was installed forward.
