Deltamarin and GTT today announced that they have received Approval in Principle (AiP) from the classification society ClassNK for the 12,500 m3 LNG dual fuel VLCC design.
eltamarin, GTT and ClassNK have been collaborating on the development of an LNG-fueled energy-efficient Very Large Crude Carrier (VLCC). According to Deltamarin, the vessel will deploy a clean-fuel technology ship containing GTT Membrane-type LNG tanks with LNG fuel stored at atmospheric pressure.
As Deltamarin noted, 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 proved, according to Deltamarin, 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.
Deltamarin claimed that the new design offers a solution that complies with the environmental regulations adopted by the International Maritime Organization (IMO) until 2030. In addidtion, the company stated that compared to a traditional oil-fueled tanker, the new LNG-fueled tanker design reduces CO2 emissions by at least 20% and offers greater autonomy without reducing cargo volume.
