METAIRIE, Louisiana – A. K. Suda Ltd. has completed the design of a 450-ft (137.25-m) truss-legged liftboat. Built by Triyards Marine, at the Saigon Shipyard in Vietnam, this vessel, which is the world’s largest liftboat, is being delivered to its owner, EMAS Offshore, of Singapore, at the end of 2Q 2014.
This vessel is a three-legged, self-propelled, self-elevating general-service workboat, known as the BH-450, and is suitable for operation in the North Sea. It has two deck cranes, one leg encircling around the starboard jackcase, with the other being a pedestal crane on the port side of the vessel. Its quarters can accommodate 250 persons including crew.
With the long legs on this vessel, this self-elevating unit is capable of working in water depths up to 367 ft (112 m). A unique feature of this vessel is its easy deployment. Unlike other vessels in this size range, this mobile offshore unit has no rack-chocks.
The liftboat is based on Suda’s model SUDA 450-L3T and is the first of a series of this design to be delivered. A second hull is already under construction.
