The Anticosti-class minesweepers were a class of minesweepers that served with the Canadian Forces from 1989–2000.
The class consisted of two former oil rig supply vessels, Jean Tide and Joyce Tide. They were acquired by Maritime Command (MARCOM) and commissioned in May 1989 with Jean Tide becoming HMCS Anticosti (MSA 110) and Joyce Tide becoming HMCS Moresby (MSA 112).[1]
Design
Laid down as Lady Joyce and Lady Jean by Allied Shipbuilders Ltd. of Vancouver, the two ships of the class were initially constructed for use as offshore drill-rig supply vessels by International Offshore Services.[2] Later renamed, they were purchased in 1988 by the Maritime Command of the Canadian Forces and converted into minesweepers.[1]
The vessels were 58.3 metres (191 ft 3 in) long with a beam of 13.1 metres (43 ft 0 in) and a draught of 5.2 metres (17 ft 1 in). Fully loaded, the ships of the class displaced 1,076 tons and 2,200 tons deep load.
Propulsion
The Anticosti class was powered by four NOHAB Polar diesel engines driving two shafts and one 550 brake horsepower (410 kW) azimuth bow thruster.[3] This created a maximum speed of 13.5 knots (25.0 km/h; 15.5 mph) and an endurance of 12,000 nautical miles (22,000 km; 14,000 mi).[1]

Service history
Prior to conversion to mine-sweeping training ships, Anticosti and Moresby deployed on initial ships' training exercises on the east coast of North America. Later, Anticosti played "orange force" to the United States Coast Guard's "blue force" in and around the waters of the states of New York and New Jersey. Anticosti also carried the flag on deployments to the west as far as Kingston, Ontario, to the east of St. John's, and to Freeport, Bermuda in the south.
After conversion, the Anticosti class was used for minesweeping training in preparation for the Maritime Coastal Defence Vessel Project, what would later become the Kingston class of patrol vessels in the late 1990s.
When the Kingston class entered service, the Anticosti class had their minesweeping equipment and armaments removed. Other modifications included the fitting of astern refueling gear to Anticosti in 1995. Anticosti was also used in the East Coast MARCOT exercise as a minelayer on at least one occasion.[3] Both ships had been decommissioned by 2000 and sold in 2002.[1]
