UK fuel decarbonisation company SulNOx has broken into the cruise ship sector through a new deal with Crystal Cruises.
Last year, the Constantine Logothetis and Idan Ofer-backed operation supplied its fuel conditioner on a trial basis to the 51,000-gt Crystal Symphony (built 1995) in Greece, Germany and Italy.
An evaluation of the product between May and December showed an average fuel saving of 3.4%.
