Cruise ships are using AI, renewable fuels, and smart tech to cut emissions and costs, despite privacy concerns.

Modern cruise ships are adopting AI, renewable fuels, and smart systems to boost efficiency and sustainability. Innovations include air lubrication to reduce hull friction, biodigesters cutting food waste by up to 40%, and recycled cooking oil used as fuel. Digital twins and AI optimize routes using real-time weather and ocean data, while sensors predict maintenance issues. Remote robots clean hulls to reduce drag, and smart cabins offer voice-activated, personalized controls. These advances, driven by major industry investments, aim to lower emissions and operating costs, though AI monitoring raises privacy concerns.
