This project demonstrates the value of trusted partnerships, combining MacArtney’s advanced mission equipment and control systems, SCA’s fabrication and EPCI expertise, and Enersea’s intelligent deck layout and integration design.
The result is a turnkey system designed to enhance operational efficiency, ensure safety, and enable swift mobilization, customized to meet the demands of modern offshore wind cable installation and repairs.
Enabling Performance Through Integration
The integrated cable lay spread includes a 4,500-t carousel, an automated loading tower with integrated tensioner, a 15-t tracked deck tensioner, a quadrant and quadrant handling system with sliding banks, cable highways, retractable stern chutes, and a range of winches.
The system is delivered as a complete package, from concept and layout to hardware and execution, backed by a streamlined mobilization philosophy designed to avoid disrupting Altera’s construction process.
“We’re really proud of this collaboration,” said Mike Welling, Business Development Manager at MacArtney Offshore Wind Solutions. “It’s a great example of how aligned partnerships can deliver true value to the offshore wind sector.”
All components are engineered for seamless integration, supporting safe, flexible, and efficient offshore operations. Delivery and mobilization onboard the Altera are planned for Q1 2026.
Looking Ahead
As the offshore wind sector continues to scale, collaboration and integration remain key to delivering efficient, future-ready solutions.
“By joining forces with SCA and Enersea, we’ve brought together the best of three worlds—innovative technology, smart engineering, and robust execution,” Welling added. “We see this as a strong foundation for future opportunities and look forward to continuing this journey together.”
This project reinforces MacArtney’s role in enabling the offshore wind industry through reliable, integrated cable lay solutions that keep offshore wind moving forward.
