From the viewpoint of the energy saving in the marine field, a development of a waste heat recovery system with high efficient is required. We have been trying to develop a marine heat recovery system with a Stirling engine generator since 2005. The Stirling engine operates with exhaust gas from a marine Diesel engine as the heat source. From 2008 to 2009, we had the endurance test of a 500 W class waste heat recovery Stirling engine, and improved an isothermal simulation model for the engine design based on a lot of experiences. From 2010 to 2011, in order to set a waste heat recovery system to an electric propulsion ship, a 3 kW class waste heat recovery Stirling engine generator was developed. In this report, we describe the results of our research project related to the waste heat recovery Stirling engine system for the electric propulsion ship. Also we discuss technical subjects for practical design, experimental results of the Stirling engine on bench tests, a development of a control system for a safety operation, and performance of the system after installation to the electric propulsion ship "Kakuyo-Maru".
