Allseas Chooses MacArtney for Electric Launch and Recovery Systems Upgrade

Leading offshore contractor Allseas has recently partnered with MacArtney to enhance their fleet by replacing existing hydraulic launch and recovery systems (LARS) with the innovative all-electric eLARS technology on three of their vessels.

The project involves the installation of three over-the-side 150 kN all-electric A-frames, complete with docking head and AHC winch, to support a new fleet of electric remotely operated vehicles (ROVs) designed for survey and construction tasks in water depths ranging from 4 to 6 kilometers.

Notably, one of the eLARS systems is slated for deployment on the renowned vessel Pioneering Spirit, recognized as the largest and most versatile offshore construction vessel globally, while the others will be installed on the dynamically positioned pipelay vessels Solitaire and Lorelay.

MacArtney’s eLARS solution offers a range of benefits, including a significantly reduced environmental impact, real-time diagnostics, enhanced efficiency, automated launch and recovery capabilities, and intelligent, upgradable control systems. Its sleek design optimizes deck space and promotes eco-friendly practices by eliminating pressurized oil contamination in water environments.

Moreover, the eLARS system incorporates high redundancy and advanced self-assessment features for preventive maintenance, leading to cost savings of up to 50% compared to traditional hydraulic systems. With remote operability from shore, the eLARS requires fewer onboard crew members and minimizes crew exchange costs. The system’s online troubleshooting capabilities ensure continuous operations, minimal downtime, and optimized resource utilization, thereby improving overall planning and scheduling efficiency.

Furthermore, the eLARS technology contributes to lower operational expenditures through the availability of cost-effective spare parts with short lead times, minimal customization requirements, simplified installation processes, and faster turnaround times facilitated by standardized components.

By investing in MacArtney’s cutting-edge eLARS systems, Allseas demonstrates its commitment to leveraging advanced technology for enhanced operational performance, environmental sustainability, and cost-effectiveness in offshore activities.
