HMCS Corner Brook
Since 2008, Babcock Canada has been providing In-Service Support to the Royal Canadian Navy’s fleet of Victoria-Class submarines. This critical work includes the provision of platform design, integration, configuration, project management services, and maintenance and waterfront support, ensuring complete life cycle engineering support.
The Submarine life cycle includes an “operational period”, where it is available to the fleet for operations and undergoes short work periods and interim dockings to complete 1st and 2nd line ongoing maintenance. Deep 3rd line maintenance or Extended Docking Work Periods (EDWPs) are when the boat undergoes extensive surveys, repairs and major capability upgrades. These long, multi-year work periods ensure the submarines remain safe, functional, and operationally capable. HMCS Corner Brook, one of four Victoria-Class submarines, successfully completed her Extended Docking Work Period (EDWP) in 2022 in Esquimalt, B.C. Repairs included fixing damage caused by a grounding in 2011 along with other maintenance routines which could only be conducted in a long maintenance period in dry dock. The EDWP included several notable upgrades such as a new communication mast, called the Universal Modular Mast, which allows high-speed, highly-secure, jam-resistant satellite communications with shore. Subsequent to the completion of the EDWP, HMCS Corner Brook will undergo camber dive and sea acceptance trials before being returned to full service.
