TRIPOD

Triple energy saving by use of CRP, CLT and podded propulsion

There is a need for fast ship transportation that is both efficient and non-polluting. Conventional propellers are known to have low efficiency. As an indicative example, most of ship propellers installed on cargo vessels waste about 40 percent of the energy in the form of rotational losses in the wake, vortex generation, noise production, cavitation, etc. The recovery of such losses is one of the major ways to contribute to a more rational, environmentally-friendly use of energy.

The main objective of the TRIPOD project is the development and validation of a new propulsion concept for improved energy efficiency of ships. The ship propulsion efficiency will be optimized through the advanced combination of three existing propulsion technologies. In particular TRIPOD explores the feasibility of a novel propulsion concept resulting from the integration of two promising EU grown technologies (podded propulsion and tip loaded endplate propellers) in combination with energy recovery based on counter-rotating propeller (CRP) principle. The three existing technologies have been used separately and are known to improve the overall ship propulsion efficiency as compared to conventional propulsion. However, they have never been combined together in a single propulsion package.
