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). Once the Kingston-class coastal defence vessels became operational, the Anticosti class was discarded and the two ships returned to mercantile use.
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. Later renamed, they were purchased in 1988 by the Maritime Command of the Canadian Forces and converted into minesweepers. 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.
The Anticosti class was powered by four NOHAB Polar diesel engines driving two shafts and one 550 brake horsepower (410 kW) azimuth bow thruster. 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).
The two ships were constructed by Allied Shipbuilders Ltd. of Vancouver and named Joyce Tide and Jean Tide. After completion Jean Tide served as an oil rig logistics support vessel for International Offshore Service of Liberia. In 1975 she was sold to Tidewater Marine. Jean Tide remained with this company until her sale in 1988.
