Tallink cuts fuel consumption by 7% with voyage optimisation technology

Tallink Grupp says the installation of Qtagg’s EcoPilot system on the cruise ferry M/S Isabelle has resulted in a 7% reduction in fuel consumption.

Built in 1989 and acquired by Tallink seven years ago, the twin CP propeller M/S Isabelle is usually deployed on a daily cruise service between Stockholm, Sweden and Riga, Latvia.

Qtagg’s EcoPilot voyage optimisation system was tested during more than 50 voyages during last summer. The reduced fuel consumption results were verified by sailing with the EcoPilot system operational and non-operational on alternate round trips.

Indrek Lepp, Master of the Isabelle, said: ‘After a period of familiarisation, EcoPilot is now in full use by Isabelle’s deck and engine officers. The system is quite new, and some initial challenges were solved with support from the Qtagg specialists. Once the deck officers fully understood the benefits and limitations of the system and operated the vessel based on that knowledge, we achieved the best fuel savings.’

Qtagg’s solution connects the entire propulsion chain, so that normally independent systems work together to optimise the ship’s performance. The system reads data from sensors monitoring more than 60 parameters in real time, including engine performance, propeller performance, rudder lift and drag forces, ship motion and navigational information. Data from previous voyages together with weather and sea forecasts are used to minimise the total fuel consumption for each voyage.

‘The 7% reduction in fuel consumption and emissions on M/S Isabelle is a great achievement,’ said Tarvi-Carlos Tuulik, CEO of Ship Management at Tallink Grupp. ‘But the crew’s involvement is crucial, and this result is also thanks to our open-minded users, professional navigators, and engineers onboard.’

Going forward, Tuulik said that the company ‘will consider implementing [EcoPilot] on other vessels.’
