Dockwise Vanguard is a semi-submersible heavy lift ship owned and operated by Dockwise B.V. The Vanguard is the largest vessel of its type ever built, and is able to carry cargoes up to 110,000 tonnes. The Vanguard was designed to move offshore oil and gas facilities, but can also carry other ships and act as an offshore dry dock facility.
As offshore oil and gas facilities have grown in size, Dockwise saw a market for a ship that could carry the largest floating oil rigs to their destinations, reducing time and costs of transportation and allowing rigs to be built economically in a shipyard. In conjunction with Finland based Deltamarin, they designed a ship called the Type-0 heavy lift vessel, later renamed Dockwise Vanguard following an in-house competition won by Gerry Sarlis.
The Vanguard has a flat bow-less deck measuring 70 by 275 metres (230 by 902 ft), allowing cargo longer and wider than the deck. Her deck is 70% larger than the MV Blue Marlin, the second biggest heavy lift ship. The bridge and living area superstructure is situated at the far starboard side, and the deck contains four movable buoyancy casings. The watertight deck allows water to flow over the deck without risking the ship.
The Vanguard is semi-submersible allowing her to lift ships or rigs out of the water, and to place them into water. When her ballast tanks are flooded, her deck lies up to 16 metres (52 ft) below the surface, allowing her to handle deep draught cargoes. Loads can then be floated above her, and her ballast tanks emptied allowing her to lift and transport cargoes up to 110,000 tonnes, 50% more than the Blue Marlin. She can also be loaded from a dock side, and large cargoes loaded by skidding them on tracks.
The first cargo of the Vanguard is Chevron Corporation's Jack/St. Malo oil platform from Samsung Heavy Industries in South Korea to the Gulf of Mexico. At 53,000 tons, Jack/St. Malo is the biggest semi-submersible floating oil platform ever built, and was loaded in February 2013. The journey is expected to take just under two months. The Vanguard has orders for two more deliveries, the Goliat FPSO later in 2013, and the Aasta Hansteen spar platform in 2015, both being built by Hyundai Heavy Industries. At 193m long, the Aasta Hansteen platform will be the largest floating spar platform produced.
The Vanguard is able to offer an offshore dry dock facility, allowing ships and floating oil rigs to be raised out of the water for inspection or maintenance without a break in production. This would save operators a huge amount of money compared with towing the rigs back to dock taking them out of service for months.
