The '''''Anticosti''-class minesweepers''' were a class of [[minesweeper]]s that served with the [[Canadian Forces]] from 1989–2000. The class consisted of two former [[Oil platform|oil rig]] supply vessels, ''Jean Tide'' and ''Joyce Tide''.  They were acquired by [[Canadian Forces Maritime Command|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 {{sclass|Kingston|coastal defence vessel|1}}s became operational, the ''Anticosti'' class was discarded and the two ships returned to mercantile use.

==Design==
[[Keel laying|Laid down]] as ''Lady Joyce'' and ''Lady Jean'' by [[Allied Shipbuilders|Allied Shipbuilders Ltd.]] of [[Vancouver, British Columbia|Vancouver]], the two ships of the class were initially constructed for use as offshore drill-rig supply vessels by [[International Offshore Services]].<ref name=shipb>{{cite web|url=http://shipbuildinghistory.com/history/canadayards/allied.htm |title=Allied Shipbuilders |publisher=shipbuildinghistory.com |access-date=27 September 2014 |url-status=dead |archive-url=https://web.archive.org/web/20141015105431/http://www.shipbuildinghistory.com/history/canadayards/allied.htm |archive-date=15 October 2014}}</ref> Later renamed, they were purchased in 1988 by the Maritime Command of the Canadian Forces and converted into [[minesweeper]]s.{{sfn|Macpherson|Barrie|2002|p=300}} The vessels were {{convert|58.3|m|ftin}} [[Length overall|long overall]] with a [[Beam (nautical)|beam]] of {{convert|13.1|m|ftin}} and a [[Draft (ship)|draught]] of {{convert|5.2|m|ftin}}. Fully loaded, the ships of the class [[Displacement (ship)|displaced]] {{convert|1,076|LT|t|lk=on}}.{{sfn|Sharpe|1990|p=83}}

The ''Anticosti'' class was powered by four [[NOHAB]] Polar SF 16RS [[diesel engine]]s driving two [[Propeller|shafts]] creating {{convert|4600|hp|lk=on}} and one {{convert|575|bhp|lk=in}} Gil Jet [[Azimuth thruster|azimuth bow thruster]].{{sfn|Sharpe|1990|p=83}} This created a maximum speed of {{convert|13.5|kn|lk=in}} and an endurance of {{convert|12000|nmi|lk=in}} at {{convert|13|kn}}.{{sfn|Macpherson|Barrie|2002|p=300}}{{sfn|Sharpe|1990|p=83}} The vessels had a [[ship's company|complement]] of 5 officers and 18 [[Naval rating|ratings]]. The two ships of the class were equipped two [[Racal Decca]] navigation [[radar]]s 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.{{sfn|Sharpe|1990|p=83}}

==Service history==
The two ships were constructed by [[Allied Shipbuilders|Allied Shipbuilders Ltd.]] of [[Vancouver, British Columbia|Vancouver]] and named ''Joyce Tide'' and ''Jean Tide''.<ref>{{csr|register=MSI|id=7301245|shipname=Lady Joyce |accessdate=21 April 2016}}</ref><ref>{{csr|register=MSI|id=7314723|shipname=Lady Jean |accessdate=21 April 2016}}</ref> 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 services)|Tidewater Marine]]. ''Jean Tide'' remained with this company until her sale in 1988.<ref name=rcnnews>{{cite web |url=http://rcnnewsmagazine.blogspot.ca/2013/05/ex-hmcs-anticosti-in-news.html |publisher=RCN News |title=Ex-Anticosti in the News |date=20 May 2013 |access-date=28 September 2014 |archive-url=https://web.archive.org/web/20160509070909/http://rcnnewsmagazine.blogspot.ca/2013/05/ex-hmcs-anticosti-in-news.html |archive-date=9 May 2016 |url-status=dead}}</ref>

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.{{sfn|Milner|2010|p=305}} MARCOM acquired two ships in March 1988.{{sfn|Milner|2010|p=305}}{{sfn|Colledge|Warlow|2006|p=51}} The ships were handed over for conversion by Fenco MacLaren Incorporated (later [[SNC-Lavalin]] Defence Programs Inc.) at [[Halifax, Nova Scotia]] and [[Ship commissioning|commissioned]].{{sfn|Macpherson|Barrie|2002|p=300}}{{sfn|Milner|2010|p=305}} ''Anticosti'' (formerly ''Jean Tide'') was commissioned on 7 May 1989 with [[Hull classification symbol (Canada)|hull number]] MSA 110. ''Moresby'' (formerly ''Joyce Tide'') entered service on 1 January 1990 with the hull number MSA 112.{{sfn|Macpherson|Barrie|2002|p=300}}

The vessels sailed to [[Marystown|Marystown, Newfoundland]] for conversion.{{sfn|Macpherson|Barrie|2002|p=300}} In April 1990 they had their mechanical sweep gear and sonar fitted.{{sfn|Sharpe|1990|p=83}} ''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]].{{sfn|Macpherson|Barrie|2002|p=300}}

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 [[Flight recorder|black box]] as part of Operation "Persistence".<ref name="tridentnews.ca">{{cite web |url=http://tridentnews.ca/Portals/0/pdfarchives/2008/sept8_2008.pdf |work=Trident |last=Beaton |first=Virginia |volume=42 |issue=8 |date=8 September 2008 |access-date=28 September 2014 |title=Ceremonies mark a decade since Swissair Flight 111 crash |archive-date=27 March 2012 |archive-url=https://web.archive.org/web/20120327052254/http://tridentnews.ca/Portals/0/pdfarchives/2008/sept8_2008.pdf |url-status=dead }}</ref> In March 1999, ''Anticosti'' sailed with ''Kingston''-class vessels {{HMCS|Kingston|MM 700|2}} and {{HMCS|Glace Bay|MM 701|2}} to the Baltic Sea to participate in the [[NATO]] naval exercise "Blue Game".{{sfn|Macpherson|Barrie|2002|p=302}}

After the ''Kingston'' class entered service, the ''Anticosti'' class was identified as surplus and ''Moresby'' [[Ship commissioning#Ship decommissioning|paid off]] on 10 March 2000. ''Anticosti'' paid off on 21 March 2000. They were sold to commercial interests in January 2002.{{sfn|Macpherson|Barrie|2002|p=300}}
