Offshore Wind Farm Support

As the demand for renewable energy solutions grows, offshore wind farms are becoming more prevalent worldwide. They range from fixed platforms in shallow water near the mainland, to miles from the coast in increasingly deeper water depths utilizing offshore floating platforms.

To assist with this effort, Phoenix offers a wide range of personnel and equipment, including inspection-class Remotely Operated Vehicles (ROVs), an Autonomous Underwater Vehicle (AUV), magnetometers, and highly qualified diving personnel to organize and carry out the safe construction, inspection, repair, and maintenance of offshore wind farms’ underwater components.

ROV/AUV Support

Phoenix offers ROVs ranging from compact, lightweight, inspection-class ROVs to complex, heavy work systems to complete underwater tasks associated with offshore wind farm support. Additionally, our Artemis AUV, equipped with acoustic, optical, and geophysical payloads, is ideally suited to provide quality surveys or optical documentation support.
