Cable Connection System for Offshore Renewable Devices Passes Testing

Apollo has successfully trialled its PALM Quick Connection System (QCS)™ for floating offshore renewables, demonstrating the robust capabilities of the system in real-sea conditions.

Developed through the Wave Energy Scotland (WES) Quick Connection Systems initiative, and with support from the Offshore Wind Growth Partnership, the PALM QCS is designed to streamline the efficient hook-up and disconnection of cables and/or moorings for floating offshore renewable devices.

During the recent trials in Orkney, the system withstood severe weather conditions, including Storm Kathleen, and demonstrated its robustness through multiple connect and disconnect operations.

This system reduces operational costs by enabling quick connections and disconnections via the winching action of a conventional tow tug. 

This process reduces time in the field for operational service vessels, whilst also reducing lost power generation time when systems are disconnected. The system allows connection and disconnection in higher sea states and removes the need for connections to be carried out on deck.

The PALM QCS is a mechanical system that can also incorporate electrical wet mate connectors bringing both together using the winching action alone.

With this technology, Apollo is set to support the offshore renewables industry, particularly the floating offshore wind sector, as it scales up with ScotWind and the Celtic Sea developments.

Apollo’s Offshore Renewables Director Nigel Robinson commented; “The successful trial of the PALM QCS in Orkney is not just a milestone for Apollo, but a testament to the powerful collaborations that drive our industry forward. We are grateful to Wave Energy Scotland, through which the PALM QCS was conceived and developed. Their ongoing support is vital to our success. 

“Equally, our thanks go to Leask Marine, who were essential as our marine contractor, and to the numerous local supply chain companies whose contributions were crucial. This trial showcases what we can achieve together to advance the future of offshore renewable energy, and we look forward to continuing these collaborative efforts in the future.”

Managing Director of Wave Energy Scotland, Tim Hurst, added; “It is reassuring to see the PALM perform exactly as Apollo hoped, including its capabilities in challenging weather conditions. Quick connection technologies are an exciting enabling development for offshore marine renewables and WES looks forward to seeing Apollo continue to develop their technology and collaborate further within the marine renewables sector.”
