The SOV will sail into SBMT harbor on battery power, recharge the battery using shore power, and depart New York Harbor. The hybrid vessel is certified to “Tier 4 emissions standards”, achieving the highest standard for marine applications.

“Equinor and bp’s agreement with Edison Chouest will generate ripple effects throughout the supply chain, creating jobs in many states across the country. With the first-of-its-kind plug-in hybrid service operations vessel, Empire Wind will reduce potential emissions from our operations in the New York area.
