9000 m3 Tanker is a part of a X-Gas project aiming to lead the charge in next generation sustainable fuel transport and bunkering. X-gas project consist of series of innovative and unconventional X-GAS bunker tankers designed by KNUD E. HANSEN.

The flagship design of the project is a 126.5 metres vessel with a total cargo capacity of 9,000 cubic metres, split between two Type C tanks. The platform, however, is highly customizable and can be tailored to accommodate a range of tank capacities, as well as various containment systems including membrane tanks.

The most unique feature of the X-gas platform is a low profile, forward deck house. This enables the vessel to safely approach and pull alongside cruise ships with low hanging lifeboats. This also minimizes the need for ballast during cargo transfer, there­by lowering operational costs. Lastly, the forward deck house allows for larger cargo tanks without impeding bridge visibility.

The design features a novel and extremely fuel-efficient diesel electric power and propulsion plant consisting of one of the most fuel efficient dual-fuel 4-stroke engines available. Integrated with the propulsion plant is an Energy Storage System (ESS) with a lithium-ion battery bank that allows for engine load optimization with reduced methane slip.
