Today in the Monfalcone shipyard of Fincantieri Mein Schiff Relax, the first of two newly developed "inTUItion" class cruise dual-fuel (liquefied natural gas and marine gas oil) that plant is being built for TUI Cruises, a joint venture between the TUI AG and Royal Caribbean Cruises groups.

With approximately 160,000 gross tons, these units will form the backbone of TUI's fleet of the future Cruises. The order is based on a prototype design developed by Fincantieri which is studying the possibility of having them operated in the future also with low-emission biofuels. The units of the class will also be equipped with catalytic converters (compliant with the Euro 6 standard) and a generative turbine that uses the waste heat of diesel generators and a electrical connection from the ground, ensuring almost emissions while in port (about 40% of the operating time). Finally, the ships will be equipped with a system of Innovative waste treatment even more efficient in able to transform organic substances into charcoal by thermal process.
