The vessel enables specialised subsea operations, making it an essential tool for offshore wind projects. With her large, robust aft deck, the Acadia is a highly flexible asset for Designed to transport and precisely place rock on the seabed, Acadia provides scour protection for subsea cables, pipelines and offshore wind turbine foundations. Following delivery, the vessel is scheduled to support offshore wind projects in the United States, including Equinor’s Empire Wind 1 project and Ørsted’s Sunrise Wind project. After completing its first projects in the United States, Acadia is planned to continue operations in the European offshore energy market through contracts secured for 2027.
