Jan de Nul orders third offshore installation vessel in China

Luxembourg-headquartered Jan De Nul has ordered a third offshore jack-up wind turbine installation vessel at Cosco Shipping Heavy Industry in China. The vessel will be the largest of its kind, with a payload of about 14,000 tonnes and a crane capacity of more than 3,000 tonnes.
Jan De Nul designed the vessel itself but Denmark’s Knud E. Hansen undertook a design review and contributed to the overall package through its previous experience in this sector. This includes the design of the Swire Blue Ocean wind turbine installation vessels, Pacific Orca and Pacific Osprey.
For this vessel, the Danish naval architecture firm provided the midship sectrion, the design of the three-chorded truss work legs, the jacking frames, the leg wells and the main crane pedastal. The company also provided finite element method strength calculations of the hull, legs and jacking frames.
