Wotan is a 500-short-ton (454 t) capacity Clyde Iron Works model 42 barge-mounted crane which is one of the largest revolving floating cranes on the West Coast of the United States.
History
editThe Wotan floating barge-crane was built for Manson Construction; the barge was sourced from New Orleans, and the crane was (reputedly) the "Little Wolf" crane used at Highland Fabricators at Nigg Yard.
Capacity
editThe Clyde Iron Works Model 42 crane can lift 500 short tons (454 t) using the main hoist on a 200-foot (61 m) boom at any point in the crane's revolution;[1] capacity rises to 600 short tons (544 t) when using the main hoist oriented astern. Motive power for the main hoist is provided by a diesel engine, and electric power for the barge is provided by a 800 KW diesel generator set.
