Proman Stena Bulk has finalised an order for two 50,000-dwt methanol-ready tankers at Guangzhou Shipbuilding International (GSI) in China.
The ships are set for delivery in 2022.
Last month Stena Bulk of Sweden and Swiss tanker manager Proman Shipping announced they had set up a joint venture to build and own methanol-fuelled tankers.
Erik Hanell, CEO of Stena Bulk, confirmed that an order for two units was finalised this week.
