Wing-in-Ground (WIG) craft development took a firm step forward with the recent announcement that two Korean companies – Daewoo Shipbuilding & Marine Engineering (DSME) and Wing Ship Technology Corp – are to co-operate to make production of WIG craft a viable operating and commercial proposition. The offshore support vessel market is in their sights, and they also have plans to develop a 200-seat WIG craft for military use.

This size of ship, sometimes referred to as Malacca-max would require a propulsion power of 103,000 kW. These vessels could be powered by a single or twin engine arrangement. [More]
