Two TUI Cruises ships are currently operating on bio-LNG, according to a statement shared on social media.
The company said that the Mein Schiff Relax and the Mein Schiff Flow are running entirely on renewable LNG during their summer seasons in Europe.
TUI noted that this greener fuel is based on biomethane, which can significantly reduce greenhouse gas emissions compared to fossil fuels.
“Thanks to the use of bio-LNG alone, we were already able to save around 26,000 tons of CO2 by July 2026 and are expected to reach around 50,000 tons by the end of the year,” the company stated.
In addition to burning cleaner fuels, TUI highlighted other initiatives aimed at improving sustainability, including the use of shorepower.
Various ships were retrofitted with connections over the past few years, including the Mein Schiff 1, the Mein Schiff 2 and the Mein Schiff 5.
Ships also use sustainable textiles and operate under the watch of dedicated environmental officers, who are said to work to keep operations as green as possible.
The company reduced the use of plastic onboard and shifted its shore excursions program to focus on environmentally friendly tours.
The Mein Schiff Relax is currently offering itineraries departing from Germany to destinations in the Baltic and Scandinavia.
After debuting earlier this year, the Mein Schiff Flow is spending its maiden season in the Western Mediterranean with cruises to Spain, Italy, France, Morocco and Portugal.
Built by Fincantieri, the 4,000-passenger vessels introduced a new design to the fleet, becoming the company’s largest ships at 161,000 tons.
TUI is now working with Fincantieri on two additional LNG-powered vessels, which are scheduled to debut in 2031 and 2032.
The 20-night cruise was scheduled to sail between Cape Town, South Africa, and Palma de Mallorca, Spain.
Before arriving in the Mediterranean, the itinerary included visits to Walvis Bay in Namibia, Praia in Cape Verde, Gran Canaria and Arrecife in the Canary Islands, as well as Tangier in Morocco and Barcelona in Spain.
TUI had already cancelled the first leg of Mein Schiff 4’s repositioning voyage, which was set to sail from the United Arab Emirates to South Africa in late March.
With the latest round of cancellations, all the cruises set to take place onboard the vessel from Feb. 28, 2026, to April 11, 2026, will no longer go ahead.
As previously reported by Cruise Industry News, the company also cancelled the repositioning cruise forthe Mein Schiff 5 and all sailings set to take place onboard the ship between Feb. 28, 2026, and March 29, 2026.
“The primary objective now remains the safety and well-being of the remaining crew onboard the Mein Schiff 4 and the Mein Schiff 5,” TUI stated.
“In addition, the TUI Cruises crisis management team is working continuously and in close coordination with the relevant authorities, the German Foreign Office, the relevant embassies, international security experts and the security teams of its two parent companies on an ongoing assessment of the situation,” the company added, mentioning the resumption of the vessels’ regular itineraries.
