Anticosti-class minesweeper
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 and "Joyce Tide" becoming . Once the s became operational, the "Anticosti" class was discarded and the two ships returned to mercantile use. 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. Later renamed, they were purchased in 1988 by the Maritime Command of the Canadian Forces and converted into minesweepers. The vessels were long overall with a beam of and a draught of . Fully loaded, the ships of the class displaced . The "Anticosti" class was powered by four NOHAB Polar SF 16RS diesel engines driving two shafts creating and one Gil Jet azimuth bow thruster. This created a maximum speed of and an endurance of at . The vessels had a complement of 5 officers and 18 ratings. The two ships of the class  were equipped two Racal Decca navigation radars operating on the I band. For minesweeping purposes, they were provided with mechanical minesweeping equipment and a high frequency, towed side scan variable depth sonar. The vessels were rated as ice class 3 and suitable for employment in light ice. Service history. 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. As part of the plan for the Naval Reserve to take over minesweeping and coastal operations, MARCOM began its effort to provide ships for training. MARCOM acquired two ships in March 1988. The ships were handed over for conversion by Fenco MacLaren Incorporated (later SNC-Lavalin Defence Programs Inc.) at Halifax, Nova Scotia and commissioned. "Anticosti" (formerly "Jean Tide") was commissioned on 7 May 1989 with hull number MSA 110. "Moresby" (formerly "Joyce Tide") entered service on 1 January 1990 with the hull number MSA 112. The vessels sailed to Marystown, Newfoundland for conversion. In April  1990 they had their mechanical sweep gear and sonar fitted. "Anticosti" was assigned to Maritime Forces Atlantic (MARLANT) as a minesweeping training vessel in preparation for the Maritime Coastal Defence Vessel Project (MCDV), which would become the "Kingston" class in the late 1990s. "Anticosti" was deployed by MARLANT in the annual MARCOT exercises as a minelayer. In March 1997, "Moresby" transferred to CFB Esquimalt. During the investigation into the Swissair Flight 111 crash in September 1998, "Anticosti" was among the Maritime Command vessels that responded to the crash site. She among the many ships scoured the sea looking for the  aircraft's black box as part of Operation "Persistence". In March 1999, "Anticosti" sailed with "Kingston"-class vessels and to the Baltic Sea to participate in the NATO naval exercise "Blue Game". After the "Kingston" class entered service, the "Anticosti" class was identified as surplus and "Moresby" paid off on 10 March 2000. "Anticosti" paid off on 21 March 2000. They were sold to commercial interests in January 2002.
