otal improve of Tallink cruise ferry’s propulsion management system will carry massive gas and CO2 financial savings.
Since September 2022, Estonian operator Tallink’s largest cruise ferry, Silja Europa has been chartered out to the Netherlands and used to deal with migrants and refugees. Normally, the vessel operates on the Baltic Sea between Helsinki, Finland, and Tallinn, Estonia, and a technical evaluate made in preparation to carry the vessel again into common site visitors has resulted in a call to exchange the whole present propulsion management system with up-to-date know-how.
As a outcome, Västerås, Sweden, based mostly Qtagg has been awarded a contract for a complete improve of Silja Europa’s propulsion management system, that can lower the ship’s gas consumption by 6% and CO2 emissions by 2,096 tons yearly. The overhaul consists of engine pace governors, gas rack actuators, pitch management and voyage optimization with Qtagg’s EcoPilot resolution.
Qtagg will provide the EcoPilot voyage optimization system, with interfaces each on the bridge and within the management room; 4 DEGO IV engine governors; 4 ASAC actuators with management models; two pitch management models and the ancillary tools wanted for a whole and built-in set up.
The governors might be put in within the engine management room, changing present Woodward management models. The governors are linked to an utility server and a system that visualizes gas consumption and offers detailed logging.
The actuator management models might be mounted within the engine room, whereas the pitch management models are put in within the present pitch management cupboard, changing the present analog rack.
EcoPilot offers the captain with actual management over the arrival time, whereas saving gas in a predictable method. The anticipated gas consumption for a voyage is routinely calculated beforehand, based mostly on the specified arrival time, chosen route and present climate reviews. In the voyage planning course of, the captain will understand how a lot gas might be consumed to carry the ship to its vacation spot and might select to regulate the arrival time or to depart earlier in an effort to optimize gas financial savings.
The gas financial savings are estimated to be about 6%, in step with financial savings recorded on Tallink Isabelle, the place EcoPilot is already put in. The gas financial savings are achieved by optimized propulsion, based mostly on the gathering and processing of enormous quantities of knowledge, together with real-time climate forecasts, sea state and ship knowledge. Once the captain has chosen a route it’s executed by the propulsion management system, and the optimum propeller pace and pitch place is utilized over the whole course of the voyage.
The anticipated annual CO2 discount for Silja Europa is 2,096 tons, which is able to contribute to a decrease EU ETS price sooner or later and a greater CII ranking for the ship.
