The success story of the E-PP began with the river cruise ship “Viking Legend”, built in 2009 by the shipyard SET in Tangermünde. In the meantime, more than 60 river cruise ships are already equipped with the E-PP system, many of them also with the control and diagnosis system E-RD. In addition, there are several innovative research vessels and mega yachts on our reference list.
