Incorporating trusted MacArtney technology, the all-electric MERMAC eA-frame addresses the growing market demand for more eco-friendly solutions.

Incorporating trusted MacArtney technology, the all-electric MERMAC eA-frame addresses the growing market demand for more eco-friendly solutions.

This cost-efficient and environmentally conscious MERMAC system features MacArtney’s proven technology, delivering over 30% improved energy efficiency compared to hydraulic systems. With zero pressurised oil over water, the risk of oil spillage is significantly reduced.

A forward-thinking technology solution, the MERMAC eA-frame is designed and manufactured in Denmark, drawing on MacArtney’s experience since 1978. It can be delivered as part of a complete Launch and Recovery System (LARS) or as a stand-alone A-frame, offering excellent versatility. The all electric system is fully customisable to meet specific customer requirements and technical specifications.

The robust design includes an optional Emergency Recovery Mode, ensuring safe recovery even in the event of a drive malfunction.

The MERMAC eA-frame offers a low cost of ownership, with a design focused on ease of maintenance. Spare parts are lightweight, readily available, and easy to replace. Maintenance requirements are significantly reduced by eliminating hydraulics, and the electronic control system ensures smooth operation, reducing wear and tear.

Plug-and-Play installation simplifies mobilisation and enhances operational efficiency by eliminating the need for hydraulic setup.

Integration with MacArtney electric winches enables the conversion of a complete LARS to one-person handling. The intelligent control system supports future upgrades, ensuring long-term versatility and value.

With a high degree of integrity and built-in redundancy, the MERMAC eA-frame minimises downtime and delivers a cost-effective, future-ready solution.
