Titan Clean Fuels has confirmed the charter of United LNG I, an 8,000-cbm LNG bunker vessel, to operate across the Zeebrugge, Amsterdam, Rotterdam and Antwerp (ZARA) region.

The 135-metre inland waterway vessel, which was launched in December 2025, is owned by Somtralux and operated by United Bunkers. According to Titan, the vessel will deliver LNG, liquefied biomethane (LBM/bio-LNG) and, in the future, renewable hydrogen-derived e-methane.

The vessel is already operational, having completed multiple LNG bunkering operations after obtaining its licence from the port. It has been particularly focused on delivering to pure car and truck carriers (PCTCs) calling at various ports in the ZARA region, Titan noted.

United LNG I features eight deepwell main cargo pumps, each delivering 165 cbm per hour of fuel, making it suitable for larger vessels. The vessel is equipped with subcoolers and a gas combustion unit for gas-up and cooldown operations, and can conduct simultaneous bunkering operations.

Designed by RensenDriessen, the vessel is compatible with all LNG tank types — including membrane, Moss and type C tanks. It features a hose handling crane and bunker boom combined with bunker manifolds, thus expanding mooring configuration options for ship-to-ship transfers.

The vessel is built to supply container vessels, large PCTCs, large tankers and cruise vessels without requiring a spacer vessel, as well as re-supplying other LNG bunker vessels.

Niels Den Nijs, Director of Titan Clean Fuels Marine, commented: "As demand for LNG and LBM increases — in line with the growth of the LNG-fuelled fleet and supported by decarbonisation drivers like FuelEU Maritime — access to high-quality bunker vessels and various terminals is vital. This chartering agreement gives us even more flexibility in delivering methane pathway fuels to ship operators now and into the future.

"At Titan, we are open to delivering any fuel that can substantially decarbonise shipping; the skillset needed for gaseous fuel bunkering is largely similar. Having said that, we currently see the clear advantages of the methane pathway in terms of availability, costs and emissions."

Den Nijs added that LBM and e-methane can be integrated into established LNG bunkering infrastructure and blended with each other at any ratio with little to no modification required to equipment.

Mr Somers, CEO of Somtralux, remarked: "United LNG I is built with conventional bunkering in mind, where we have a proven track record. We are pleased to also venture into LNG bunkering now and see Titan as a good partner going forward. The vessel is versatile and is capable of more complex operations, so it fits perfectly with Titan's operations."

The announcement follows Titan's acquisition by Molgas Energy Group, backed by infrastructure investor InfraVia, in October 2025.

Titan is a physical supplier of LNG, LBM and, in the future, hydrogen-derived e-methane to the shipping sector. The company has been operating in the bunkering sector for over 10 years and is based in Amsterdam.

United Bunkers is a physical marine fuel supplier serving the ARA region, including key ports surrounding Antwerp and Rotterdam. The company is owned by the Somers family, who have an operating history of more than 43 years in physical transportation of liquid products.

Headquartered in Madrid, Molgas Energy Group operates downstream LNG and renewable gases across Europe, providing a range of services, including ship-to-ship, truck-to-ship and terminal-to-ship operations.
