A joint venture between Equinor and bp has awarded the first plug-in hybrid service operations vessel (SOV) with batter capability in the US to marine transportation provider Edison Chouest Offshore (ECO), the company said on Friday. Empire Offshore Wind chose ECO for the service at the new Empire Wind offshore wind farm in the US. The vessel is part of a long-term SOV charter agreement with Empire Offshore Wind, a joint venture between Equinor and bp developing the wind farm near Long Island. The US-flagged vessel will be Jones Act compliant and have its home port at the new operations base that Empire Wind will develop at the South Brooklyn Marine Terminal in New York, the company said in a statement. It will be constructed with components from Edison Chouest's US supplier base, it said.
