The profitability of waste heat systems for marine vessels depends on the vessel's operating profile, the price of the heavy fuel oil, the turbocharging efficiency requirements of the main engine, the available efficiency of the turbochargers and, finally, the type and cost of the system itself. The paper first provides an overview of current technologies and experience to date. Using the calculation results for a specific application as basis, three different waste heat system configurations - a system with stand-alone power turbine, a system with only a steam turbine, and a system combining the power turbine and steam turbine - are analyzed with respect to electric power output, fuel oil saving and CO2 emissions. The economic and technical parameters affecting the waste heat systems are also investigated. An evaluation of new technologies suitable for integration in waste heat recovery systems further shows the potential for improved performance when variable turbine geometry is applied to the power turbine.
