The SS Clan Forbes was a British cargo steamship. She was built for Clan Line Steamers Ltd as one of its Cameron-class steamships. She was launched at Greenock in 1938, served in the Second World War and was scrapped in Hong Kong 1959.
Clan Forbes was launched on 8 September 1938 and completed that December. She was one of a sub-class of 11 Cameron-class ships of identical dimensions, built in 1937–41 by the Greenock Dockyard Company on the River Clyde at Greenock in Renfrewshire: Clan Buchanan, Clan Cameron, Clan Campbell, Clan Chattan, Clan Cumming, Clan Ferguson, Clan Fraser, Clan Forbes, Clan Lamont, Clan Menzies and HMS Engadine.
Clan Forbes had 20 corrugated furnaces with a combined grate area of 402 square feet (37 m2) heating five single-ended forced draught boilers with a combined heating surface of 17,780 square feet (1,652 m2) that supplied superheated steam at 220 lbf/in2 to a pair of three-cylinder triple-expansion steam engines. Each reciprocating engine had a 48 inches (1.2 m) stroke; the cylinder bores were 26 inches (0.66 m) high pressure, 42 inches (1.1 m) intermediate pressure and 68 inches (1.7 m) low pressure. Steam exhausted from the low-pressure cylinders then drove a pair of low-pressure steam turbines with double reduction gearing and hydraulic couplings to twin propeller shafts. J G Kincaid and Company of Greenock built the four engines, whose combined power was rated at 1,370 NHP.
