Sustainable subsea solutions for the future of offshore wind

As offshore wind projects expand in scale and complexity, new approaches to subsea protection are emerging. Combining long-term durability, environmental sensitivity and engineering innovation, these solutions are helping to stabilise infrastructure, protect marine ecosystems and accelerate the shift to renewable energy.

The original patented Kyowa Filter Unit® Rockbag provides a long-term, maintenance-free solution for safeguarding the subsea assets of offshore wind farm developments. Constructed from 100% Japanese recycled ultra-clean PET (rPET), it offers exceptional flexibility, making it highly adaptable to complex marine projects.

Ridgeway Rockbags are engineered to withstand high-flow velocities due to their porous design, making them the ideal solution for protecting subsea foundations and cables.

Currently, Van Oord is using Rockbags for CPS cable works at RWE’s Sofia Offshore Wind Farm in the North Sea from its base at the Port of Blyth. This project is part of the Dogger Bank offshore wind development, located 195 km off the UK’s East Coast, covering an area of 593 square kilometres. The development will consist of 100 turbines, each with a 14 MW capacity, totalling 14 GW of installed power. Scheduled for commissioning in 2026, the wind farm is expected to supply clean energy to 1.2 million UK homes, significantly contributing to the UK’s 2030 clean power target.
