Offshore handling systems specialist Caley Ocean Systems has been awarded a contract to supply dredging and marine engineering company Jan de Nul with a 5,400 tonne capacity cable turntable for the vessel Willem De Vlamingh.

In mid 2013, Jan de Nul will install the 245kV export cable connecting the Northwind offshore windfarm on the Lodewijkbank off the coast of Oostende to the Belgian power grid.

In the first quarter of 2013, Willem De Vlamingh will be being outfitted for cable laying offshore. Caley is undertaking all vessel modification design work and construction of the 28m diameter turntable on deck.

In addition to the 5,400 tonne storage capacity turntable, Caley is supplying a modular loading tower assembly comprising loading arm, inboard chute, tensioner and control cabin.

To ensure smooth loading and deployment of the cable offshore, the Caley turntable includes an integral 5 tonne tensioner and 10 tonne deck tensioner.

“Caley Ocean Systems has the experience in the design and manufacture of large turntables needed to ensure timely delivery of the cable lay installation,” said Frederik Deroo, senior manager vessel construction, at Jan de Nul.
