A digital twin-optimized routing solution developed by Adrena in collaboration with Brittany Ferries and Bureau Veritas Solutions M&O France has demonstrated fuel savings of up to 6 percent, the company said in a press release.

The solution, which is said to deliver measurable reductions in fuel consumption while maintaining operational reliability, schedule integrity and service quality, has now been deployed across nine vessels in the Brittany Ferries fleet.

It was validated through thousands of commercial voyages and nearly two years of onboard monitoring aboard the Galicia, one of Brittany Ferries’ E-Flexer-class vessels.

“The results achieved on the Galicia confirm what we have been developing for close to 15 years: a routing and consumption prediction model with 97% reliability, validated here under real commercial operating conditions and strict ETA constraints,” said Michel Rodet, Adrena chairman and founder.

“This level of accuracy has been proven in the field, not in a simulated environment. It was measured on actual crossings, by an independent body, over almost two years of study. It is this rigor that allows crews to trust AdrenaShip’s recommendations and fully realize the operational and environmental benefits.”

Adrena has been developing the AdrenaShip routing software since 2012 for the maritime transport sector, providing shipowners and fleet operators with an intelligent routing tool designed for the real-world constraints of maritime operations.

Brittany Ferries and Adrena first launched AdrenaShip in 2016 to improve fuel efficiency and operational safety through route optimization and performance analysis, delivering fuel savings of approximately 4 percent.

Six years later, Brittany Ferries expanded the partnership to include BV Solutions to develop vessel-specific digital twins that enhance the predictive capabilities of AdrenaShip.

The digital twins are said to improve the accuracy of routing recommendations and provide guidance on machinery operation by combining operational data, engineering expertise and onboard experience.
