SUDA 450-L3T, a 450-foot (137.25-meter) truss-legged liftboat, designed by A. K. Suda, Ltd. and built by Triyards Marine, Saigon Shipyard in HCMC, Vietnam, reported to be the world’s largest liftboat, is being delivered to its owners, EMAS Offshore of Singapore at the end of 2nd Quarter 2014.

This state-of-the-art 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 is an ABS classed with Unrestricted Service, DP-1, Accommodation Service DRC, and carries a Wind Farm Installation Maintenance and Repair Certification. The molded steel hull dimensions are 60m x 54m x 6m. It has two deck cranes, one leg encircling around the starboard jackcase, and the other, a pedestal crane on the port side of the vessel. The quarters arrangement 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 feet. A unique feature of this vessel is its easy deployment. Unlike other vessels in this size range, this Mobile Offshore Unit has no rackchocks.

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.
