DeepOcean engaged by Vattenfall for subsea cable support

3 April 2025 – Ocean services provider DeepOcean has been awarded framework agreements by Vattenfall for the provision of subsea cable Operations and Maintenance (O&M) services, now valid for Vattenfall’s operational European offshore wind portfolio.

The framework agreements are valid for a period of four years and apply to Vattenfall’s offshore wind farms in Denmark, the United Kingdom, Germany, the Netherlands, and Sweden.

“We welcome the opportunity to support Vattenfall’s generation of renewable energy through this framework agreements. We have over 25 years’ experience in subsea installation and Inspection, Maintenance and Repair (IMR) work. We look forward to applying our specialist expertise to Vattenfall’s subsea infrastructure,” says Øyvind Mikaelsen, CEO of DeepOcean.

Wide scope of services

Under the framework agreements, DeepOcean will provide project management, engineering, pre-installation surveys, offshore transportation of cables, trenching, cable installation and jointing, termination and testing, post-installation surveys, plus recovery and disposal of damaged cables. The scope is specific to Vattenfall’s operating assets, which introduces additional requirements in terms of response time and technical ingenuity. DeepOcean will utilize its personnel in Norway and the UK, to conduct project management and engineering work for call-off orders under the framework agreement.

“We are excited to enter this collaboration with DeepOcean, an experienced and versatile provider of subsea services. With a substantial asset base in offshore wind and a promising long-term project pipeline, we have historically enjoyed strong relationships with our suppliers and industry. This partnership with DeepOcean aligns with our mission to deliver reliable, and cost-effective energy solutions while never compromising our high health and safety standards,” says Pavlo Malyshenko, Head of Generation at Vattenfall.

A first call-off under the frame agreement structure has been executed for an O&M work scope at a European offshore wind farm. DeepOcean mobilized the subsea vessel Olympic Ares, which was converted with cable lay equipment and a jet trencher onboard, for the scope and future offshore renewables assignments.
