Largest CSD Newbuild Underway at Kinderdijk
01 Jan 2003
Construction of the world's largest self-propelled cutter suction dredger is now in full progress at IHC Holland's Kinderdijk shipyard. The vessel for Belgian contractor Jan de Nul is due to be launched in May of this year with sea trials to follow in the autumn.
The 140.7m long dredger will be powered by three 8,400kW main engines, allowing a maximum speed of 12 knots when in transit between projects.
Equipped for all-weather operation, it will be able to work in temperatures ranging from -20ºC to +45ºC and in seawater temperatures up to 36ºC.
Some 6,000kW of power to the cutterhead will see it cutting through the hardest material at depths to 35m. One 3,800kW underwater pump and two 6,000kW inboard pumps are connected in series to enable long pumping distances.
Loading barges alongside will also be possible via two barge loading pipes and a barge mooring system.
Meanwhile, IHC Holland delivered the 3,000m 3capacity trailing suction hopper dredger Mellina last month for client K. Krul & Zonen, a subsidiary of the Netherlands' Koop Group.
The twin screw vessel features an 800 mm internal diameter suction pipe on the starboard side capable of dredging to depths of 35m. The 94.4m loa dredger will carry its 5,500 tonne maximum load at speed of 12 knots.
