Galway Port has welcomed the inaugural visit of Thun Renew, one of Europe's most environmentally advanced coastal tankers, marking the start of a new twice-monthly fuel service to the west of Ireland. The vessel arrived on Thursday carrying a cargo of fuel oil and will now make regular calls to Galway, helping to maintain regional energy supplies while supporting lower-emission coastal shipping.

Built in 2026 by Ferus Smit Shipyard in Leer, Germany, Thun Renew is the third vessel in the Erik Thun Group's new R-Class series. The tanker has been designed to reduce emissions, improve fuel efficiency and enhance onboard conditions for its crew. A key feature of the vessel is its ability to operate in emission-free mode while sailing in Irish waters, including Galway Bay, supporting wider efforts to reduce the environmental impact of maritime transport.

Captain Brian Sheridan, Interim CEO of Galway Port, welcomed the ship's arrival. "We are delighted to welcome Thun Renew to Galway for the first time," he said. "This vessel represents the future of coastal shipping, combining operational efficiency with innovative environmental technology. Its ability to operate carbon-free in Irish waters demonstrates how the shipping industry is embracing sustainable solutions while continuing to provide essential services to regional economies."

The Netherlands-flagged tanker is 115 metres long, has a deadweight of 7,999 tonnes, and can carry 9,500 cubic metres of oil and chemical products across 10 coated cargo tanks.

Galway Port says the vessel's regular deployment highlights both the continuing importance of maritime trade to the region and the growing adoption of low-emission technologies across the European shipping industry.
