Denmark’s Terntank has exercised options to build two LNG-powered 15,000 dwt product tankers at China’s Avic Dingheng Shipbuilding.

The newbuildings are slated to be delivered from the shipyard in the first quarter of 2016 and the first quarter of 2017 respectively.

Finland’s oil firm NEOT has agreed to charter the new vessels upon deliveries.

"Terntank elected to declare its two options because there is considered to be a demand for energy efficient and environmentally adapted tanker tonnage," Terntank said.

It added that the newly built ships will also emit 35-40% lower volumes of CO2 than a conventional tanker today.

Including the latest orders, Terntank now has four 15,000 dwt product tankers on order at Avic Dingheng.

The earlier twin vessels ordered are scheduled for deliveries in February and May 2016 respectively.
