Integrated design of asymmetric aftbody and propeller to maximize energy efficiency

With the implementation of the EEDI, energy saving and emission reduction of ships, especially merchant ships, become more and more important. To achieve high efficiency and low emissions, recently Energy Saving Devices (ESDs) have been re-studied and installed to many ships, both new buildings and also retrofits. Due to the fact that most ESDs are fitted in the wake field however, the performance of the ESDs is influenced by scale effects.
