The project ran three years 4 STATE-OF-THE-ART between 2002 and 2005 and was sponsored by the European Commission through the Fifth 4.1 Introduction Framework Program (FP5). The principal The following is an update on some objective of the FASTPOD project was to high-profile pod related R&D activities, explore a new design technology to exploit the interesting landmark applications of pod driven benefit that can be offered when using electric ships, dedicated international conferences and pod drives on commercial large and fast ships other related events to reflect on the state-of-the-art on pod propulsion since the 24 th (35-40kts) in an efficient, safe and environmental friendly manner. ITTC reporting. SES (Super Eco-Ship) projects in Japan has been promoting many novel coastal ships 4.2 Research and development activities driven by podded propulsion system. The In Europe, under the EC Framework projects started from 2001 and can be divided Programme (FP5), a 3 year RTD project into two projects. SES phase1 is a project for FASTPOD (Fast Ship Applications of for Pod developing new technology concerned with Drives) participated by 17 EU partners from 7 electric propulsion system including podded EU countries was completed in early 2006. propulsor and the research programme was The principle objective of the FASTPOD finalised in 2005 and the project has established project was to explore a new design technology economical supporting system of new buildings to exploit the benefits that can be offered when of novel ships with electric driven propulsor. using electric pod drives on commercial large The second project is called SES phase 2 and and fast ships (35-40 knots) in an efficient, safe the project aims to develop combined system of and environmentally friendly manner. The marine gas turbine and pure CRP podded project explored the potential applications of propulsor. The first vessel of SES phase 1 conventional pod motor technology on a “Shin-ei Maru” was delivered 2007 and the conventional ropax (38 knots) and container first vessel of SES phase 2 “Shige Maru”was ship (35 knots) as well as a trimaran cargo 2008. vessel (40 knots) using numerical and experimental methods.
