CCGS Earl Grey is a Samuel Risley-class light icebreaker and buoy tender in the Canadian Coast Guard. Constructed in 1986, the vessel serves a variety of roles, including light ice-breaking and buoy tending, as well as being strengthened for navigation in ice to perform tasking along the shores off the Atlantic coast of Canada. Like her sister ship, CCGS Samuel Risley, she carries a large and powerful crane on her long low afterdeck for manipulating buoys. Earl Grey is the second icebreaker in Canadian service to carry the name.
The design of the vessel is based on offshore supply-tugboat designs, with strengthened chines. The vessel has a tall foredeck, and a long low quarterdeck, for carrying buoys, where a crane with a capability of lifting 15 long tons (15 t) is permanently mounted. The crane is motion stabilized.Earl Grey is 69.7 metres (228 ft 8 in) long overall with a beam of 13.7 metres (44 ft 11 in). The icebreaker has a draught of 5.2 metres (17 ft 1 in). Earl Grey displaces 2,935 long tons (2,982 t) and has a 1,988 gross tonnage (GT) and a 642 net tonnage (NT).
The ship is powered by four Deutz 4SA 9-cylinder diesel-electric engines driving two controllable pitch propellers that create 8,836 horsepower (6,589 kW). This gives the vessel a maximum speed of 15 knots (28 km/h). The vessel has a capacity of 634 m3 (22,400 cu ft) of diesel fuel that gives Earl Grey a range of 18,000 nautical miles (33,000 km) at 11 knots (20 km/h) and the vessel can stay at sea for up to 58 days. The ship is equipped with one Caterpillar 3306 emergency generator.
