The rope-walk at Chatham, Kent, produced anchor ropes and was the longest brick building in Europe when constructed.
The British Royal Navy dockyards were the largest industrial organisation in the world during the 18th Century, and could make every part of a warship from a mast to a nail guns were the exception, and they came from the Board of Ordnance. The scale of the military-naval industry could be large in maritime nations, even discounting civilian yards. The efficiency gains - admittedly with some new risk of fire, as the main shipbuilding material is wood - are impressive! This can be used to drive sawmills, lathes, even block-making machines and as the lifting power for dockside cranes. Using steam to power these engines is an obvious keep, but once steam engines are in a dockyard this goes far beyond pumping seawater around. The kind of beam engines used to pump water around a canal system (and drain mines) can drain a drydock efficiently. A steam drydock is a magnificant achievement of an industrializing nation: a manufactory of ships without equal!
