HMCS Chicoutimi's Extended Docking Work Period Nears Completion

HMCS Chicoutimi was under tow to Ogden Point April 16 to conduct a camber dive. This was a key moment in the submarine’s Extended Docking Work Period that began in 2010.


The camber dive is an early stepping stone in Chicoutimi’s return to the fleet, expected later this year, as it advances through an extensive test and trial program.

A camber dive verifies the submarine’s watertight integrity, as well as the functionality of communications and other key systems. Dives occur in protected harbours where the water is deep enough for the submarine to be fully submerged.

Before returning to operational service, a submarine must be certified following the successful completion of alongside tests and sea trials. The submarines must also be manned with a qualified and experienced crew, and be deemed safe to sail, conduct trials, and execute operations in accordance with their readiness status.

Chicoutimi will return to operational service with the Royal Canadian Navy once it completes its period of testing and trials required under the tiered readiness program. The submarine is expected to complete testing and trials by mid-2014.
