Seaspan has entered into a five-year contract worth $500 million to perform dry-dock maintenance on Canada’s navy frigates. The contract is estimated to support approximately 400 jobs a year at the shipyard, which employs about 1,100 workers in various trades. The contract is Seaspan Victoria Shipyards’ share of a $1-billion federal maintenance program for Canada’s 12 Halifax-class frigates. The ships were first launched in the 1990s and are considered the workhorses of the Royal Canadian Navy. The initial five years of the contract will see each of the yards perform maintenance work on three frigates, expected to begin in the early 2020s. A similar deal is now being finalized with Irving Shipyards in Nova Scotia.
