CCGS Edward Cornwallis[a] is a Martha L. Black-class icebreaker of the Canadian Coast Guard. She serves as a light Icebreaker and buoy tender on the East Coast of Canada. Entering service in 1986, the vessel is homeported at Dartmouth, Nova Scotia. The vessel is named after Lieutenant-general Edward Cornwallis, a British Army officer and founder of Halifax, Nova Scotia.

Design and description[edit]

Edward Cornwallis and sister ship CCGS Sir William Alexander differ from the rest of the class by having one less deck in the superstructure and their buoy-handling derricks mounted forward.[1] Edward Cornwallis displaces 4,662 long tons (4,737 t) fully loaded with a 3,727.2 gross tonnage (GT) and a 1,503.0 net tonnage (NT). The ship is 83.0 metres (272 ft 4 in) long overall with a beam of 16.2 metres (53 ft 2 in) and a draught of 5.8 metres (19 ft 0 in).[2][3]

The vessel is powered by is propelled by two fixed pitch propellers and bow thrusters powered by three Alco 251F diesel-electric engines creating 8,847 horsepower (6,597 kW) and three Canadian GE generators producing 6 megawatts of AC power driving two Canadian GE motors creating 7,040 horsepower (5,250 kW).[2][3] The ship is also equipped with one Caterpillar 3306 emergency generator. This gives the ship a maximum speed of 16 knots (30 km/h). Capable of carrying 783.7 long tons (796.3 t) of diesel fuel, Edward Cornwallis has a maximum range of 6,500 nautical miles (12,000 km) at a cruising speed of 13.7 knots (25.4 km/h) and can stay at sea for up to 120 days. The ship is certified as Arctic Class 2.[3]

The icebreaker is equipped with one Racal Decca Bridgemaster navigational radar operating on the I band. The vessel is equipped a 980 m3 (35,000 cu ft) cargo hold. Edward Cornwallis is equipped with a flight deck and a hangar that can house two light helicopters of the MBB Bo 105 or Bell 206L types.[3] However, the vessel is only allotted one helicopter.[2][3] The ship has a complement of 25, with 10 officers and 15 crew. Edward Cornwallis has 9 additional berths.[3]

Operational history[edit]

The ship was constructed by Marine Industries at their yard in Tracy, Quebec with the yard number 450.[4] Edward Cornwallis was launched on 24 February 1986 and entered service on 14 August 1986.[2][4] The ship is registered in Ottawa, Ontario, and homeported at Dartmouth, Nova Scotia.[2][3]

On 17 December 2007, Edward Cornwallis was dispatched to recover the 140-metre (459 ft 4 in) barge Houston carrying diesel fuel that had cast adrift in St. George's Bay near Port Hood, Nova Scotia. Facing 70 km/h (43 mph) winds and 5-metre (16 ft) waves, members of the crew boarded the barge. They rescued the crew and kept the barge from going aground until a tugboat arrived on 19 December. Five members of the crew were later awarded medals for their efforts.[5]
