LR Grants AIP for LNG Dual-fuel VLCC Design

GTT and Deltamarin have obtained an approval in principle (AIP) from Lloyd’s Register for their design of a dual-fuel very large crude carrier (VLCC), which incorporates a 12,500m3 liquefied natural gas (LNG) tank equipped with GTT’s Mark III Flex membrane technology.

The concept developed by GTT aims at maximizing vessel autonomy thanks to a large-capacity tank, giving shipowners and charterers the benefit of longer trade navigation with a single refueling operation, without any impact on cargo capacity.

Deltamarin and GTT explored various configurations and solutions to integrate this cutting-edge tank into the design. By leveraging advanced simulation tools and a holistic approach, the project not only delivers an LNG-powered vessel, but also sets new standards in energy efficiency and emissions reduction for VLCCs.

This innovative design fully complies with the environmental regulations set forth by the International Maritime Organization (IMO) until 2030. Compared to traditional oil-fueled tankers, this LNG-fueled VLCC design reduces CO2 emissions by at least 20%, while extending the operational range of vessels without compromising cargo capacity.
