Margaret Brooke (AOPV 431) is the second Harry DeWolf-class offshore patrol vessel for the Royal Canadian Navy. The class was derived from the Arctic Offshore Patrol Ship project as part of the National Shipbuilding Procurement Strategy and is primarily designed for the patrol and support of Canada's Arctic regions. Named after Sub-Lieutenant Margaret Brooke, a and who tried to save another person during the sinking of the ferry SS Caribou during World War II. Margaret Brooke was ordered in 2011, laid down in 2016 and launched in 2019. The vessel began contractor sea trials in May 2021, and it was delivered to the Royal Canadian Navy for post-acceptance sea trials on 15 July 2021.

Design and description[]

The Harry DeWolf-class offshore patrol vessels are designed for use in the Arctic regions of Canada for patrol and support within Canada's exclusive economic zone. The vessel is 103.6 m (339 ft 11 in) long overall with a beam of 19.0 m (62 ft 4 in). The ship has a displacement of 6,615 metric tons (6,511 long tons). The ship has an enclosed foredeck that protects machinery and work spaces from Arctic climates. The vessel is powered by a diesel-electric system composed of four 3.6-megawatt (4,800 hp) generators and two diesel engines rated at 4.5 megawatts (6,000 hp) driving two shafts. Margaret Brooke is capable of 17 knots (31 km/h; 20 mph) in open water and 3 knots (5.6 km/h; 3.5 mph) while icebreaking in new year ice of 1-metre (3 ft 3 in) thickness. The ship is also equipped with a bow thruster to aid during manoeuvres and docking procedures without requiring tugboat assistance. The ship has a range of 6,800 nautical miles (12,600 km; 7,800 mi) and an endurance of 85. Margaret Brooke is equipped with fin stabilizers to decrease roll in open water but can be retracted during icebreaking.[1][2][3]

Margaret Brooke is able to deploy with multiple payloads, including shipping containers, underwater survey equipment or landing craft. Payload operations are aided by a 20-metric-ton (20-long-ton; 22-short-ton) crane for loading and unloading. The ship is equipped with a vehicle bay which can hold can pickup trucks, all-terrain vehicles and snowmobiles. The ship also has two 8.5-metre (27 ft 11 in) multi-role rescue boats capable of over 35 knots (65 km/h; 40 mph). The ship is armed with one BAE Mk 38 25 mm (0.98 in) gun and two M2 Browning machine guns. The patrol ship has an onboard hangar and flight deck for helicopters up to the size of a Sikorsky CH-148 Cyclone. Margaret Brooke has a complement of 65 and accommodation for 85[1][2][3] or 87.[4]

Service history[]

The order for the Arctic Offshore Patrol Ships was placed on 19 October 2011 with Irving Shipyards of Halifax, Nova Scotia as part of the National Shipbuilding Procurement Strategy.[5] The ship was to be constructed in 62 blocks, which were then pieced together into three larger blocks. These three "mega blocks" would be fitted together to form the hull of the ship.[1] On 13 April 2015 the government announced a second ship would be named Margaret Brooke in honour of Margaret Brooke. During World War II, Brooke, a navy nursing sister, was decorated for her actions during the sinking of the passenger ferry SS Caribou.[6][7] The vessel's keel was laid down on 29 May 2017[8] and the vessel was launched on 10 November 2019.[9] The ship was scheduled to begin contractor sea trials in May 2021.[10] The vessel was delivered to the Royal Canadian Navy for post-acceptance sea trials on 15 July 2021.[11]
