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.
Client: Babcock Canada
Project Date: Q2 2021
Industry: Department of Defense
NB Scope: Nickel Bros partnered with Babcock Canada to perform the planning and execution of the 3,980,000lbs Corner Brook Submarine Undocking.
Project Specifics include:
- Install of transport frames under submarine within hanger/shed
- Performed scaling/weighing of submarine prior to transport
- Performed the safe site transport and barge loading of the 3,980,000lbs Submarine
- Loaded submarine over Ro-Ro Ramps onto submergible barge/floating drydock
- Successfully cooperated with Shipyard Firms and Trades to perform delivery
Cargo Specifics (LWH@lbs):
- 232’x38’-11”x53’-11”@3,980,000lbs
Transport Distance:
- 400 m
Challenges:
- Multiple obstructions on move pathway including buildings
- Appropriate displacement and equipment capacity for exceptional cargo weight
- Active shipyard trades to schedule around
- Installation of frames in congested areas
Solutions:
- Survey of all Shipyard obstructions and the careful planning of Submarine movements for transport operations
- Multiple SPMT utilized for lift and movement of cargo (72 Lines) and weighted proof roll to test ground conditions and assimilate axle loadings prior to cargo movement
- Coordination and establishing delivery and other trade pathways for during move
