Refitting the Last Corvette, HMCS SACKVILLE

Although SACKVILLE last received a refit and maintenance during a docking period in 2018, that refit identified a number of critical areas that still required attention, and money and time were limited. After receiving new funding, the ship has once again been docked via the Navy's Syncrolift and Submarine Maintenance Facility, and is undergoing more work. I'll provide a more detailed report as time goes on, but for now will share some photos of the docking itself on September 24th. 


Once on the lift, the ballast tanks were pumped out, and the ship was lifted the rest of the way.


Although divers have removed the majority of the growth on the ship's bottom, some growth remained and was cleaned off in the coming weeks using high pressure water. The sacrificial anodes were in very good shape.






Once the lift was secured, the ship was pulled forward into the maintenance building. The previous customer, HMCS WINDSOR, recently completed a refit in the same shed.


The tug pulls the ship along this chain.

The refit is expected to last into the spring, and will involve the cladding of critical areas of the ship's existing plating under the waterline. This refit is intended to buy the ship another 10 years before more significant work needs to be done.
