Power routing will reduce fuel costs by 6-8% for Corsica Linea

VÄSTERÅS, Sweden - June 10, 2024 - PRLog -- Qtagg recently secured an order on a digitalization of M/S Danielle Casanova's propulsion control system, that will reduce the ship's fuel consumption by an estimated 6-8%. The order includes power routing with EcoPilot and retrofit of governors, actuators and the pitch control system.

Danielle Casanova is the largest of Corsica Linea's nine cruise ships that serves routes between the French continent, Corsica, Algeria and Tunisia. The vessel is currently at port in Marseille for maintenance and technical upgrades.

Power routing for improved fuel economy
On Daneille Casanova, Corsica Linea has decided to install EcoPilot, a fully automated eco-driving system that uses weather forecasts and ship data to calculate the best power plan for a route and a set arrival time. It also implements continuous adjustments to maintain an even engine load and propeller pitch optimization for maximal fuel savings.

This type of automated eco-driving does not require the captain to manually change either speed or pitch. Instead, the active power routing provides the captain with full control over the arrival time and mitigates the human tendency to set a higher speed than necessary at the start of a voyage.

Upgrades of governors, actuators & pitch control
EcoPilot controls the ship's propulsion system with instructions to the engine governor and the pitch control. Danielle Casanova will be equipped with new DEGO IV engine governors, new ASAC actuators and a new pitch control system. These will replace outdated technology and enable digital ship propulsion control and active power routing with EcoPilot.

Fuel savings guarantee
The EcoPilot power routing system comes with a 3% fuel consumption reduction guarantee, but the expected savings for Daneille Casanova is in the interval of 6-8%, based on a somewhat conservative calculation based on installations on similar vessels.

The actual fuel reduction will be determined by a 4–5-week test period after commissioning. The fuel consumption during this period will be compared to a baseline from a reference period where the ship operates without EcoPilot. The comparison will be confirmed by a statistical analysis to compensate for any influence from varying environmental, load and speed conditions.
