NN-SPM estimates ship fuel consumption taking into consideration weather and operational conditions.
This repository contains 'example_dataset' that was built using:
- Weather forecast data collected from NOAA for the experimental area in the North Pacific
- Forecasts of FuelMassFlow generated from systems that are modelling ship energy system
- Vessel is assumed to sail at constant speed, water depth, draft
- For each weather combination, three different COGs are contained with the resulting FuelMassFlow estimate
Input features (n=9):
- wind speed (m/s)
- wind direction (degree)
- significant wave height (m)
- peak wave period (s)
- wave direction (degree)
- primary swell height (m)
- primary swell period (s)
- primary swell direction (degree)
- course over ground (degree)
Output (n=1): Fuel Mass Flow (kg/s)
