The energy transition needs subsea expertise. We've been building it for over two decades.

DeepOcean has spent more than 25 years developing subsea capabilities across the world's most demanding offshore environments. As the offshore wind industry has scaled, we've grown with it - applying our remotely operated vehicle (ROV) technology, specialist vessel fleet, and engineering expertise to the unique challenges of renewable energy infrastructure.

Today, we support fixed and floating offshore wind projects across every phase - from early-stage survey work through to cable installation, ongoing inspection and maintenance, and end-of-life decommissioning.

Windstaller Alliance

The Windstaller Alliance was formed by DeepOcean, Aker Solutions, and Solstad Offshore. The partnership combines the expertise of three offshore industry leaders to deliver a highly flexible service offering for offshore renewables and marine operations. The objective is to cut the number of supplier interfaces by reducing technical and commercial project risk through better integration of services, project management, and asset utilisation.
