MacArtney successfully delivered the world's first and largest all-electric Launch and Recovery System (eLARS™), aligning with Jan De Nul's dedication to a sustainable energy transition.

Jan De Nul was intrigued by MacArtney's eLARS™ for their Offshore Support Vessel Symphony and the new cable trencher Swordfish. 

Investing in its modern offshore installation fleet, Jan De Nul found MacArtney's break from conventional hydraulic systems consistent with the wish to implement innovative technology providing operational reliability and supporting the commitment to a needed energy transition.

Operational reliability through clever design

Built on MacArtney's tried and tested technology, the all-electric eLARS™ provides benefits that ensure reduced downtime, increased operational efficiency and reliability. 

"It is indeed a remarkable system," the Jan De Nul team states. "It is precise, easy to operate and monitor, and implements well with the entire set-up and our effort to support the green transition. The cooperation with MacArtney has been constructive with good sparring on the technical details."

Compared to traditional hydraulic systems, the eLARS™ significantly lowers maintenance costs via reduced spare parts requirements and no need for regular hose changes and filter replacements. Furthermore, the absence of pressurised oil over water enhances safety and environmental sustainability.

Its compact design optimizes deck space utilization, allowing for efficient installation and operation.

A notable feature is the intelligent self-assessment capability for preventive maintenance. It identifies and notifies users of potential failures, enabling proactive measures to be taken before any critical issues arise. The eLARS™ also boasts a high level of redundancy, ensuring continuous functionality even if one or more electrical systems are damaged.

The next-level integrated control system can be operated remotely from shore, enhancing convenience and streamlining operations. 

Scope of supply

The supplied eLARS™ system includes an eA-Frame, Docking Head, and Winch. The leg height of the eA-Frame is 14 metres, with an 11-metre distance between them. The 500 kN A-frame has a safe working load of 50 tonnes and advanced PLC technology, allowing full remote system control.

Collaboration leading to a world premiere

Joining expertise and an environmentally friendly approach, the collaboration between Jan De Nul and MacArtney led to the development of an optimal solution, based on the smaller eLARS™ prototype, for their large-scale launch and recovery needs to operate their innovative new-built trencher - the Swordfish. 

Koos van der Zee, MacArtney's Head of Project Management, is enthusiastic about the teamwork: "We have put the world's first and largest eLARS™ system to sea. Client engagement played a crucial role in shaping the final layout. Together, we optimised and introduced new technology supporting the needs of Jan De Nul now - and in the future."

Energy shift in maritime industries

"There is a genuine wish to support the energy shift in the maritime industries," Sales Director Marine & Offshore, René Rasmussen, concludes, "and the eLARS™ solution has generated significant interest with several upcoming projects in the pipeline."
