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[edit]
The 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[edit]
The 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.
