    Within EU Project TRIPOD, new ways of saving energy are being studied to improve ship operational costs. The main objective of the TRIPOD project is the development and validation of a new propulsion concept for improved energy efficiency of ships which is based on the combination of three existing propulsion technologies. In particular TRIPOD explores the feasibility of integrating podded propulsors and tip loaded endplate propellers into energy recovery systems based on counter rotating propeller (CRP) principle. A non-rotatable pod unit called Rudderpod is installed behind the ship main propeller. CRP units consisting of different combinations of CLT and conventional propellers are being analyzed in ballast and load conditions for a retrofit and a new building scenario. CFD tools and model tests are combined to facilitate the design process. A method for the extrapolation of model tests to full scale and another for the accurate estimation of effective wakes by CFD tools have been developed. TRIPOD includes the realization of an economical cost benefit analysis for the operation of a reference ship
