Frequensea is an innovative technology company pioneering sustainable solutions for subsea infrastructure removal in the offshore energy industry. Established with a focus on responsible decommissioning and circular re-use of cables and pipelines, the company has developed a patented vibration-assisted method that enables the safe, efficient, and environmentally responsible retrieval of subsea assets. By creating methodologies to recover and repurpose infrastructure with minimal ecological impact, Frequensea actively closes the loop between installation, operation, and re-deployment, driving the transition toward a more circular offshore energy value chain.

As the offshore energy sector advances, both offshore wind and offshore oil and gas assets are reaching end-of-life stages where sustainable decommissioning is essential. Traditional removal techniques are energy-intensive, costly, and disruptive to the seabed. Frequensea’s controlled vibration technology fundamentally redefines this process by reducing soil resistance around buried infrastructure—allowing cables and pipelines to be retrieved with smaller vessels, lower energy consumption, and minimal seabed disturbance, while preserving materials for reuse.

With its strong focus on innovation, cost efficiency, and sustainability, Frequensea is setting a new standard for end-of-life management in offshore energy. Its scalable, low-impact technology offers a transformative pathway toward cleaner, safer, and more circular offshore operations—positioning Frequensea as a frontrunner in the global offshore decommissioning market.
