The Royal Canadian Navy‘s (RCN) Halifax-class frigate HMCS Halifax has returned to service after successfully completing its docking work period (DWP).

HMCS Halifax was originally docked on 20 October last year at Canadian company Irving Shipbuilding’s Halifax Shipyard, which serves as the in-service support centre of excellence for the navy’s Halifax-class vessels.

The DWP required an investment of more than $30m and included a series of routine maintenance works and upgrades to ensure the longevity of the frigate.

Work on the project was carried out by more than 530 employees from the shipyard and included 440 apprentice and journeyperson crane operators, electricians, engine fitters, ironworkers, joiners / stagers, labourers, material handlers, pipefitters, riggers and welders.

The DWP also saw the involvement of more than 60 suppliers.

Irving Shipbuilding president Kevin McCoy said: “The Halifax-class is a true representation of the skill and expertise of the workforce at Irving Shipbuilding.

“Having built, modernised and maintained these frigates so they can continue to be the backbone of the RCN fleet, our workforce knows the Halifax-class better than any shipyard.”

The frigate was the first of seven RCN east-coast Halifax-class ships to complete a mid-life upgrade programme as part of the Canadian Government’s Halifax-class modernisation initiative.

The vessel’s mid-life refit was conducted at Halifax Shipyard from 2010 to 2012.

RCN’s HMCS Fredericton arrived at the shipyard to undergo a scheduled DWP earlier this month.
