MacArtney to upgrade ROV operations on three Allseas vessels

Allseas has selected MacArtney to enhance and future-proof its remotely operated vehicle (ROV) operations with the replacement of three existing hydraulic launch and recovery systems with the all-electric eLARS.

The scope covers three over-the-side 150 kN all-electric A-frames, including docking head and AHC winch, for a new fleet of electric ROVs used in survey and construction tasks to water depths of 4-6 kilometers.

One system will be mobilized on Allseas’ offshore construction vessel Pioneering Spirit, while the others are planned to be mobilized on the DP pipelay vessels Solitaire and Lorelay.

According to MacArtney, eLARS offers a low environmental impact, real-time diagnostics, high efficiency, automated launch and recovery, and intelligent, upgradable control systems. Its streamlined design optimizes deck space and supports green practices by eliminating pressurized oil contamination over water.

The eLARS solution incorporates high redundancy and intelligent self-assessment for preventive maintenance, reducing costs by up to 50% compared to hydraulic systems, and can be operated from shore, the company said.

“We are excited to support Allseas in their transition to electric LARS, equipping their fleet with progressive and reliable technology. Our collaboration has been outstanding throughout the process, with valuable and productive feedback ensuring the solution aligns perfectly with Allseas’ objectives,” said René Rasmussen, Sales Director Marine & Offshore at MacArtney.
