Jan De Nul picks tensioner systems provider for entire CLV fleet

Jan De Nul has appointed MacArtney Offshore Wind Solutions to design and deliver custom tensioner systems for its entire cable-laying vessel (CLV) fleet.

MacArtney’s scope implies the design, construction and delivery of advanced CEMAC tensioner systems for Jan De Nul’s CLV fleet that includes the Connector, Willem de Vlamingh and Fleeming Jenkin – said to be the world’s largest CLV, as well as upgrading tensioner systems previously delivered for the Isaac Newton.

For the XL Fleeming Jenkin, MacArtney will supply three high-capacity CEMAC four-track main deck tensioners designed to facilitate bundled lay operations with minimized cable distance and combined lay operations up to 150 tonnes, two CEMAC loading arm tensioners and associated fully electrical 1-tonne cable engines.

“Being re-selected by Jan De Nul Group for the supply of mission equipment signifies a testament to our competencies. Our dedicated team of construction and automation engineers is motivated by the challenge of aligning with the vessel’s dynamics and control system seamlessly. We are committed to ensuring that Jan De Nul Group keeps playing a leading role in pioneering the cable installation market with their advanced fleet,” said Mike Welling, Business Development Manager at MacArtney Offshore Wind Solutions.

According to the company, all CEMAC tensioners will be driven by electric motors and feature active front-end drive technology in line with the commitment to sustainable practices. This is set to ensure efficient cable tension and facilitate energy regeneration, which is redirected back to the vessel’s power plant which includes batteries.

All equipment is fully integrated with the vessel’s central control system. The solution is future-proof and designed to handle Jan De Nul’s advanced export and interconnect cable installations, MacArtney said.

This collaboration follows MacArtney’s delivery of the world’s first all-electric launch and recovery system (eLARS) to Jan De Nul, announced in October 2023.
