Holland’s Royal Boskalis Westminster NV, which placed the world’s largest heavylift semi-submersible, Dockwise Vanguard, into service last year, is proposing to build an even bigger vessel that could carry Dockwise Vanguard on its back. Boskalis has not disclosed the dimensions of the new giant, but illustrations show it carrying a loaded Dockwise Vanguard.
Completed in 2013, Dockwise Vanguard has a deck space of 270m by 70m and can carry up to 117,000 tonnes. According to Boskalis, the larger ship would be used to transport floating production, storage and offloading (FPSO) units and floating LNG (FLNG) vessels. JS
