Abstract
This study investigates the application of advanced data processing and machine learning techniques for determining the sea state encountered by a ship in a seaway. Measurements of the wave-induced responses on a large ship during transoceanic voyages are processed and utilized to derive estimates of the wave parameters and spectra in the experienced seaway.
The proposed methodology leverages various machine learning techniques, such as LightGBM and Artificial Neural Networks (ANN). The use of reanalysis data from freely-accessible public repositories – like ERA5 from the European Centre for Medium-Range Weather Forecasts (ECMWF) – is evaluated for its adequacy in model training and testing purposes. The preliminary results demonstrate the efficacy of machine learning techniques in enhancing the accuracy and reliability of sea state estimates.
Providing reliable, real-time information about the local wave conditions is crucial for ship operators and onboard decision-support systems, facilitating efficient decisionmaking and enhancing safety and fuel efficiency in maritime operations.
