Hull, Propeller and Gas Turbine efficiency decay: Data Analysis with Minimal Feedback

The proposed dataset is the result of experiments carried out by means of a numerical simulator of a naval vessel (Frigate), characterized by a COmbined Diesel ELectric And Gas (CODLAG) propulsion plant. The different blocks forming the complete simulator have been developed adopting Matlab and Simulink frameworks and fine-tuned over the years by means of real operational data of similar propulsion plants. These blocks describe the behaviour of the main components of a Naval Propulsion System, which are the gas turbine (GT), the gas turbine compressor (GTC), the hull (HLL), and the propeller (PRP). In view of these observations, the available data are in agreement with a possible real vessel. In this release of the simulator, it is also possible to take into account the performance decay over time of the PRP Thrust, PRP Torque, the HLL, the GTC and GT, according to several vessel parameters. A series of measures (25 features) which indirectly represents the state of the system subject to performance decay has been acquired and stored in the dataset over the parameter's space.
