The vessel has also been installed with a fuel meter to measure fuel con-sumption and verify fuel sav- ings, and a control system to operate the rotor either manually or automatically. Also the vessel’s crew has completed ship handling training at the Faculty of Maritime Sciences in Leer. Using the ship han- dling simulator at the faculty crews has been able to better handle the maneuvering characteristics of a

Flettner Rotor vessel. Meanwhile FEHN POLLUX returned to normal duties operating between ports in the Mediterranean, the Black Sea, Northern Eu- rope and the Baltic.
