Dutch owner Acta Marine is aiming to steal a march on rivals with a contract for low-carbon wind farm vessels in Turkey.

The Van Oord family-backed company said it has signed a deal for two next-generation construction service operating vessels (CSOVs) at Tersan Shipyard for delivery in the second and third quarters of 2024.

No price has been revealed, but the contracts come with options for two more ships in the series.
