The workshops are still in regular use by the Docks engineers.
The dock maintenance workshops are survivors from the 1880s. Much of the original machinery survives, including a Whitworth planing machine, a Whitworth slotting machine, punching-and-shearing machines, a long-bed lathe and a steam hammer. There is also wall-mounted line-shafting and a Tangye horizontal engine and Cornish boiler. The building is a Scheduled Monument, like the rest of the yard.
The line shafting is being renovated and fitted with a hydraulic motor so that it can be used to power some of the machinery, Work is well advanced on the planing machine.
