As part of the contract, certain modifications will be made to the Dockwise Vanguard to accommodate the loading of the Concordia in her current state. The operation is planned to take place around mid-2014 and contract value of the work scope as described amounts to approximately USD 30 million.

The Dockwise Vanguard is the world's largest semi-submersible ship uniquely positioned to lift and transport extremely heavy cargoes in a dry and safe manner. The ship was initially designed to transport offshore oil and gas structures, but can also carry other vessels and act as an offshore dry dock facility. The Dockwise Vanguard has an open and flat stern and bow-less deck measuring 275 meters by 70 meters allowing the vessel to transport cargo longer and wider than the deck dimensions. When the ballast tanks are flooded, the ship deck submerges below the surface, allowing her to handle deep draught cargoes. Once the Dockwise Vanguard is semi-submersed, the floating Concordia will be brought in position above the deck and as the ballast tanks are emptied, the entire ship including the Concordia is brought above the water line allowing her to transport the cargo in a safe and swift manner.
Boskalis views this project as strategically important demonstrating the opportunities for combining maritime services and assets across the breadth of the company. Furthermore, the use of the Dockwise Vanguard for this extreme salvage operation shows the versatility of the vessel. The recently announced transportation of a FPSO, a recent successful dry docking operation and this salvage transport contract award demonstrate the potential of the vessel.
