The Rotor sail system was installed on the 9,700 DWT Ro-Ro carrier M/V Estraden at the end of 2014 and the vessel has operated in continuous service between the Netherlands and the UK, sailing through the North Sea at speeds of 16 knots.
The trials were measured and analysed with continuous monitoring systems from maritime data analysis, software and services provider, NAPA and VTT Technical Research Centre of Finland. VTT Technical Research Centre of Finland collected data over a six-month period, during which both the Rotor Sail technology and automation system was operational 99% of the time. The results confirmed that the Rotor Sail is able to produce large amounts of thrust force, which enables considerable fuel savings.
