Advertisement The X-gas project is a series of innovative and unconventional, medium-capacity LNG bunkering tankers designed by KNUD E. HANSEN. The flagship design of the project is a 126.5 m vessel with a total cargo capacity of 9000 m 3, split between two Type C tanks. The platform, however, is highly customisable 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 minimises the need for ballast
