General – Tensioners
MacArtney Offshore Wind Solutions has been hired by Jan de Nul to design and supply custom CEMAC tensioner systems for its entire cable laying vessel (CLV) fleet, which includes the world’s largest cable layer – the Fleeming Jenkin.
MacArtney’s comprehensive scope involves designing, constructing, and delivering advanced tensioner systems for Jan De Nul Group’s CLV fleet, including the Connector, Willem de Vlamingh and the new Fleeming Jenkin.
The scope also encompasses upgrading tensioner systems previously delivered for the Isaac Newton CLV.
For the Fleeming Jenkin CLV, MacArtney will supply three high-capacity CEMAC four-track main deck tensioners designed to facilitate bundled lay operations with minimised cable distance and combined lay operations up to 150 tonnes, two CEMAC loading arm tensioners and associated fully electrical
The vessel will boast a cable carrying capacity of 28,000 tonnes and is engineered for ultra-deep laying in waters up to 3,000 meters, as well as bundled lay operations.
In line with the commitment to sustainable practices, all CEMAC tensioners provided by MacArtney will be driven by electric motors and feature active front-end drive technology. This innovative approach ensures efficient cable tension and facilitates energy regeneration, which is redirected back to the vessel’s power plant, which includes batteries.
