HMCS Shawinigan is a Kingston-class coastal defence vessel that has served in the Canadian Forces and the Royal Canadian Navy since 1997.

Shawinigan is the fifth ship of her class which is the name for the Maritime Coastal Defence Vessel Project. She is the second vessel to use the designation HMCS Shawinigan.

Shawinigan was laid down on 26 April 1996 at Halifax Shipyards Ltd., Halifax and was launched on 15 November 1996. She was officially commissioned into the Canadian Forces on 14 June 1997 at Trois Rivières, Quebec and carries the pennant number 704.[2]

She is assigned to Maritime Forces Atlantic (MARLANT) and is homeported at CFB Halifax.

Design

The Kingston-class coastal defence vessel was conceived to use commercial off-the-shelf (COTS) equipment and construction techniques in a ship designed to military specifications. The construction of the design required the building of partially outfitted steel block units, which were assembled into larger blocks and those blocks were integrated into the ship. The decks were assembled upside down with pre-outfitting of the underside of the deck prior to installation on the ship. The ship is outfitted with a degaussing system from Power Magnetics and Electronic Systems.[3]

Kingston class vessels are designed to carry up to three 6.1-metre (20 ft) ISO containers with power hookups on the open deck aft in order to embark mission-specific payloads.[4]

Armament and Sensors

Kingston-class vessels are outfitted with a Bofors 40 mm 60 mk5C rapid fire gun, and two 12.7mm machine guns. The ships are equipped with one of three modular mine countermeasures systems: the deep sea Thales MMS mechanical mine sweeping system, the route survey system or the Sutec remotely operated vehicle (ROV) mine inspection system.[3]

The navigation equipment installed in Kingston-class vessels are a Kelvin Hughes I-band navigation radar and a global positioning system. The surface search radar is the E to F-band Kelvin Hughes 6000.[3]

Propulsion

The ship is equipped with four main Wärtsilä UD 23V12 diesel engines which are coupled to four alternators (600 V AC). Two Jeumont electric motors (±740 V DC) provide power to the two LIPS Z-drive azimuth thrusters which are fitted with fixed-pitch reversing propellers. The propulsion system provides 15 knots (28 km/h) maximum continuous speed. The range at the economical cruising speed of 9 knots (17 km/h) using two engines is 5,000 nautical miles (9,000 km) with a 20% margin in tank capacity. Mechanical minesweeping is carried out at 8 knots (15 km/h). The crash stop length is five ship lengths from a speed of 15 knots (28 km/h).[3]

Operational history

The ship in Boston Harbor

After commissioning she was assigned to Atlantic fleet. On 28 June 1998 Shawinigan took part in the 75th anniversary of the naval reserves at Halifax and was featured on a commemorative stamp issued for the event.[2]

In August 2014, Shawinigan took part in Operation Nanook, an annual joint military exercise performed in northern Canada.[5] During that deployment, Shawinigan set the record for travelling the furthest north of any ship in the history of the Royal Canadian Navy, reaching a maximum latitude of 80 degrees and 28 minutes north. In March 2015, as part of Operation Caribbe, Shawinigan, along with HMCS Goose Bay and the US frigate USS Kauffman, intercepted a vessel in the Caribbean Sea carrying 1,017 kilograms (2,242 lb) of cocaine.[6][7]
