Edison Chouest Offshore has entered into a contract to install a battery-on-board system on a US-flagged platform supply vessel.

The Louisiana-based, privately held shipowner announced the move on Monday and said it was the first-ever such contract for a system that will reduce the unnamed vessel's carbon footprint during operations and standby periods.

"In pursuit of our long-term vision for renewable energy development and reduced emissions, Edison Chouest Offshore strives to improve efficiency through technology and innovation," executive vice president Dino Chouest said.
