Deltamarin and GTT have received Approval in Principle (AiP) from the classification society ClassNK for the 12,500 m3 LNG dual fuel VLCC design. The AiP was received from NK 1st March 2023.
Deltamarin, GTT and ClassNK have been collaborating on the development of an LNG-fueled energy-efficient Very Large Crude Carrier. The vessel will meet current and future environmental targets by deploying a well-studied, pre-approved and truly clean-fuel technology ship containing GTT Membrane-type LNG tanks with LNG fuel stored at atmospheric pressure.
In close cooperation with GTT, Deltamarin studied different arrangements and solutions for placing the tank on the vessel. The ship’s energy efficiency was studied with the latest simulation tools and a holistic approach, providing not only a vessel using LNG as fuel but also the best possible efficiency with low emissions in this ship size class.
The approval from ClassNK proves that the onboard integration of a membrane fuel tank solution is technically feasible on an LNG-fueled tanker and that it meets all safety regulations. The new design offers a solution that complies with the environmental regulations adopted by the International Maritime Organization (IMO) until 2030. Compared to a traditional oil-fueled tanker, the new LNG-fueled tanker design reduces CO2 emissions by at least 20%. It also offers greater autonomy without reducing cargo volume.
The joint development between GTT and Deltamarin has innovated a holistic approach to overall efficiency and optimized for specific sea routes while taking into account hull form, propulsion, LNG containment system and power plant configuration.
