Design and description
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. Samuel Risley 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). Samuel Risley has a gross tonnage (GT) of 1,967 and net tonnage (NT) of 649.5.
The ship is powered by four Wärtsilä Vasa 16V22 12-cylinder geared diesel-electric engines driving two controllable pitch propellers that create 6,595 kW (8,844 hp). This gives the vessel a maximum speed of 13 knots (24 km/h). The vessel has a capacity of 692 m3 (24,400 cu ft) of diesel fuel that gives Samuel Risley a range of 16,700 nautical miles (30,900 km) at 12 knots (22 km/h) and the vessel can stay at sea for up to 58 days. The ship is equipped with one General Motors 6–71 emergency generator.
The vessel is equipped with two Racal Decca navigational radars using the I band. Samuel Risley is a light icebreaker and has an ice class of Arctic Class 2, which certifies that the ship has the capability to break ice up to 2 feet (0.61 m) thick. The vessel has a complement of 22, with 9 officers and 13 crew.
Operational history
Ordered in 1983, the ship was launched in 1984 by Vito Steel Boat & Barge Limited at their yard in Delta, British Columbia with the yard number 161. The vessel was completed on 4 April 1985. After completion, the ship sailed to eastern Canada, transiting the Panama Canal and deploying to the Great Lakes. The ship is assigned to the Central Region, based at Parry Sound, Ontario.
In January 2015, Samuel Risley and CCGS Griffon worked to free several ships that had become icebound on the St. Clair River. In April, Samuel Risley was one of four icebreakers sent to rescue ten commercial vessels trapped in ice near Whitefish Point, Michigan.
In June 2016 Samuel Risley underwent a major refit by Newdock – St. John's Dockyard Ltd. Work is expected to last until September 2016. The cost of the contract was $3.6 million CAN. The refit involves the replacement of the bow thruster, a crane overhaul and recoating of the hull, along with a renovation of the galley and inspections.
