This week Uljanik shipyard in Pula, Croatia, began the construction of the Multi-Purpose Vessel JDN8628 which is being built for Jan De Nul Group.
This versatile vessel can be equipped with two cable turntables with a total capacity of 10,000 tonnes. For Subsea Rock Installation the vessel can carry up to 10,000 tonnes of rock. The rock is unloaded by two excavators and discharged through a fall pipe with ROV down to waterdepths of about 400 m.
The fall pipe installation is a further development of the system used on the vessels La Boudeuse and Willem De Vlamingh, but has been adapted to install rock at greater depths. Two active heave compensated cranes, an A-frame and a workclass ROV further enhance the capabilities of the vessel.
The newbuild will be launched by the end of this year, and be operational by mid 2015.
