There may be no fully LNG-fuelled cruiseships on the water as yet, but they are on the way.

Shipbuilders will deliver 133 LNG-fuelled newbuildings to various shipping sectors over the next six years, and 23 of them are passengerships ordered by six cruiseship companies, according to DNV GL statistics.

Carnival Corp has placed nine of those orders, while Hurtigruten has contracted six LNG-powered vessels.
