Thun Tankers said it has declared an option for a fifth tanker to be added to the previously contracted four 17,500 dwt IMO II product/chemical tankers on order at Avic Dingheng Shipbuilding Ltd in China. The sister ships (lenght 149.8 meters., beam 22.8 m. and draft 8.5 m.) are due for delivery between April 2019 and January 2020 and will be commercially managed by Furetank Chartering, responsible for the intermediate segment within the Gothia Tanker Alliance. In addition to the five contracted intermediate vessels, Thun Tankers together with the Gothia Tanker Alliance partners Furetank Rederi AB and Rederi AB Älvtank have previously ordered another six 16,300 dwt high quality intermediate tankers with LNG propulsion. One of these six vessels will go to Thun, three to Furetank and two to Älvtank. These vessels, that currently are under construction, are being built at the same yard as the now contracted vessels and will be delivered between 2018 and 2020.
