Dockwise Vanguard is semisubmersible 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 m below the surface, allowing her to handle deep-draught cargoes.
Loads can then be floated above her, and her ballast tanks empty, 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 dockside, and large cargoes can be loaded by skidding them on tracks. Dockwise Vanguard can accommodate a crew of 40.

Dockwise Vanguard has a flat, bow-less deck measuring 70 by 275 m, allowing cargo longer and wider than the deck. Her deck is 70% larger than the MV Blue Marlin, the third-largest heavy-lift ship. The bridge and living area superstructure are situated at the far starboard side, and the deck also contains four movable buoyancy casings.
