Brittany Ferries has achieved fuel savings of up to 6% by implementing a digital twin-enabled routing system. The solution was developed in collaboration with Adrena and Bureau Veritas Solutions Marine & Offshore.
Why it matters
The system improves voyage planning by using vessel-specific digital twins to optimize routes, helping the fleet reduce energy consumption while maintaining operational reliability.
Brittany Ferries realized a 6% fuel reduction after nearly two years of monitoring on the vessel Galicia. The technology is currently deployed across nine ships serving routes between France, the UK, Guernsey, Ireland, and Spain.

The routing system works by combining operational information with real-time performance data to create digital twins for each ship. This process allows captains to adjust voyage plans for maximum energy efficiency.
Timeline
2016: AdrenaShip launched through a partnership between Brittany Ferries and Adrena.
2022: Bureau Veritas Solutions joined the ongoing partnership.
Past two years: Onboard monitoring validated the system performance on the Galicia.
Travel Outlook
The shipping industry is increasingly adopting digital twin technology to mitigate the environmental impact of cruise and ferry operations. This development follows the broader trajectory of the AdrenaShip routing system as a model for reducing energy consumption in maritime travel.
While these efficiency gains primarily impact the operator, they represent a broader trend toward sustainable practices that could eventually influence industry-wide cruise pricing. Travelers monitoring their carbon footprint may see more companies adopting similar fuel-saving technologies in the coming years.
The takeaway
Using digital twins to monitor ship performance allows operators to make small but significant improvements to fuel efficiency. Travelers can track these industry advancements to see how major lines are balancing environmental responsibility with operational demand.
