Work starts on multipurpose vessel for Jan de NulVessel & ROV News // June 6, 2014
In the first week of June 2014, Uljanik Brodogradiliste in Pula, Croatia, started work on the construction of a multipurpose vessel, JDN8628, for dredging and marine contractor Jan de Nul.
The versatile vessel can be equipped with two cable turntables with a total capacity of 10,000 tonnes. For 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 water depths 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 as yet unnamed vessel will be launched by the end of this year, and be operational by mid-2015.
