Arne Blystad's OHT has criticised the cost of rival Eneti's $330m new wind turbine installation vessel (WTIV).
The former Scorpio Bulkers firmed up a contract for the ship at South Korea's Daewoo Shipbuilding & Marine Engineering earlier this month.
The NG-16000X newbuilding was first announced in August 2020 at a cost of up to $290m, but TradeWinds has reported that specifications have since been upgraded.
