The steam pump house is a rectangular shed constructed of rendered blockwork walls. A metal truss roof supports gabled corrugated iron roof. There are additional concrete walls on all but the western side (the building originally abutted a hillside on the west) built as blast barriers. The building houses a travelling crane gantry, boilers and two steam driven duplex pumps with connecting oil pipelines to pump oil to and from ships and onshore storage tanks. The pump house was constructed in 1927-28.
