Ideally suited for offshore jobs such as repairs and construction, diving, pipe laying, well intervention procedures and other activities requiring a safe and stable platform and a large .
scrollThe Levingston 400LE is a self propelled, self elevating MOU (mobile offshore unit) vessel capable of working in water depths of 20 feet (6 meters) to 250 feet (76 meters) and has a deck load capacity of 1,500 metric tonnes (1,670 short tons). The Levingston 400LE has over 1,022 sq. meters (11,000 sq. ft.) available deck space making it ideally suited for such offshore jobs as repairs and construction, diving, pipe laying, remedial well workover, drilling, and other activities requiring a safe and stable platform. The vessel can also be fitted with a cantilever and small derrick with well offset of 60 feet aft of the bow at a hook load of 150 tonnes.
