Babcock HMCS Corner Brook Undocking

This project commissioned in 2021 by Babcock Canada for the Department of Defense got all of our teams collaborating! To undock the HMCS Corner-Brook submarine, our teams needed first to install transport frames under the Corner-Brook within its hanger, enabling us to weigh it precisely prior to transport (it weighed in at an extraordinary 3,980,000 lbs / 1990 T!). Thanks to the cooperation of other Shipyard Firms and Trades, Nickel Bros was able to transport the Corner-Brook over-site and load it using ro-ro ramps onto a submergible barge / floating drydock for its future sailings.
