HMCS Max Bernays

January 20, 2024

There was no planning here. I was driving the Sambro Loop past Portuguese Cove when I spotted the HMCS Max Bernays heading to sea past Chebucto Head so I drove down to Duncan's Cove where I photographed it. It was just luck.

Max Bernays (AOPV 432) is the third 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.

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 will have 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 will be powered by a diesel-electric system composed of four 3.6-megawatt (4,800 hp) MAN 6L32/44CR[2] four-stroke medium-speed diesel generators and two electric propulsion motors rated at 4.5 megawatts (6,000 hp) driving two shafts. Max Bernays will be capable of 17 knots (31 km/h; 20 mph) in open water and 3 knots (5.6 km/h; 3.5 mph) in 1-metre (3 ft 3 in) first-year sea ice. The ship will also equipped with a bow thruster to aid during manoeuvres and docking procedures without requiring tugboat assistance. The ship will have a range of 6,800 nautical miles (12,600 km; 7,800 mi) and an endurance of 120 days. Max Bernays will be equipped with fin stabilizers to decrease roll in open water but can be retracted during icebreaking.[8][4][9]

Max Bernays will be 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 pickup trucks, all-terrain vehicles and snowmobiles. The ship will also have two 8.5-metre (27 ft 11 in) multi-role rescue boats capable of over 35 knots (65 km/h; 40 mph). The ship will be 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. Max Bernays will have a complement of 65 and accommodation for 85[8][4][9] or 87.[10]

Construction and career

The patrol vessel's keel was laid down on 5 December 2018 by Irving Shipbuilding at Halifax, Nova Scotia.[11] The ship was launched on 23 October 2021, and was delivered to the Royal Canadian Navy 2 September 2022.[12] The naming ceremony was conducted on 29 May 2022 in conjunction with that for sister ship Margaret Brooke.[13] The ship began sea trials in July 2022.[14]

The ship was delivered to the RCN in September 2022 for post-acceptance trials and it was indicated that she would be the first vessel of her class to be based in the Pacific region, starting in 2023.[15][16]
