Carrying the next generation of offshore mega-structures ///

In February, the world’s largest semisubmersible heavy transport vessel set out on its maiden voyage, carrying the world’s largest semisubmersible offshore platform hull. The Dockwise Vanguard performed its first float-on operation in South Korea, where it was built, before carrying the Jack/St Malo hull, which weighs almost 56,000 tons, to Kiewit yard in Ingleside, Texas. It is expected to reach its destination in early May.
