Feature 5 | HEAVY-LIFT Dockwise meets market demand
With the ever expanding offshore oil and gas market, demand for larger equipment to be delivered across the oceans is rising. Dockwise has developed its Type-0 vessel design to meet the future needs of this market.
bigger than its current largest vessel. Te Type-0 will have a capacity of 100,000tonnes and a decksize of 275m x 70m with a total investment of US$200 million in to the project. “The development of the Type-0 came
D
from looking into the type of cargo that it is currently transporting and from this predicting what the client will want in the future. This also involved looking at the current capabilities of heavy-liſt vessels on the market. From this Dockwise looked at developing a vessel that would give more flexibility and be capable of much larger cargoes. Bigger production platforms are

larger cargoes the vessel is wider and longer, and has a larger sailing draſt. Another feature of the vessel is that it does not have a normal bow, but has been removed to enable it to carry longer cargoes, such as a long spar buoy and FPSO’s. Te vessel can also submerge 16m about
the main deck. The vessel’s
strength and propulsion power has been specially developed for carrying out specific heavy-liſt work. “At the moment our largest vessel is capable
of 72,000tonnes, but in reality probably only handles around 60,000tonnes, which is the Blue Marlin. Te Type-0 will be able to handle up to 110,000tonnes”, comments Mr Seij. Te vessel will be 275m in length overall
and 270m in length between perpendiculars and moulded breadth of 70m. Te vessel
