En route: Dockwise Vanguard with Jack-St Malo hull

The world’s largest semi-submersible heavy transport vessel Dockwise Vanguard has started her maiden voyage carrying the weighty Jack-St Malo platform hull destined for the eponymous field in the Gulf of Mexico.
The Dockwise-operated newbuild unit departed earlier this week from Samsung Heavy Industries’ Geoje yard in South Korea after a successful float-on operation of the 56,000-tonne hull that took four hours to complete.
The vessel is set to sail around the Cape of Good Hope before arriving at the Kiewit yard in Ingleside, Texas in mid-April ready for topsides installation later the same month, with the Chevron-operated field due on stream next year.
The Vanguard, delivered from South Korean builder Hyundai Heavy Industries at the end of last year, has been designed to carry mega-heavy offshore structures that can be integrated at a single site, with a deck spanning 275 by 70 metres and a 110,000-tonne loading capacity.
