| Summary: | The preparation, conduct, and analysis of sea trial have been going through many developments over recent years because of the introduction of the Energy Efficiency Design Index (EEDI). As international standards get more stringent, requirements for a ship's performance prediction accuracy must follow suit. This presents the prospect of developing new correction methods and improving present methods. In-house capabilities to perform sea trial analysis is needed for this purpose. This project aims to develop and validate a Python program that performs Sea Trial Analysis with a selected set of correction methods. The modules are firstly evaluated together through the comparison of the deviation acquired when compared to reference source. The individual modules that have major errors are then worked on individually. The modules that are validated include Stawave1 and Displacement module. More research needs to be done for direct power method module and temperature and density module. Improvements in interpolation of CX and CXI will significantly reduce the percentage error. |
