The Schottel Twin Propeller is equipped with two propellers rotating in the same direction. The optimum matching of the system components "propellers" and "housing with integrated fins" results in a considerable increase in efficiency as compared with systems incorporating just one propeller.

The Schottel Twin Propeller (STP) is ideally suited as a propulsion system for all ships in the medium speed range with application-related higher propeller loads. The predicted improvements in efficiency have already been considerably surpassed in actual operation.

The advantages of the STP are gaining more and more recognition from shipowners and shipyards.
