Ship fuel consumption is affected by ship speed and ocean environmental factors, which are resistance to ships. There have been not only mainly theoretical studies due to the difficulty of obtaining real ship experiment data, but also insufficient studies on correlation analysis between ship speed and ocean environment factors. In this study, we performed data pre-processing work to interpolate and integrate multi-type and shape data acquired by real ship experiments. Using the integrated data, we analyzed an empirical correlation between FOC and ship speed, ocean environmental factors (wind, current, wave). Navigation experiments for collecting data were performed on five voyages, starting at Busan Port, Ulsan Port, and Ulleungdo Island. FOC data was extracted from the electronic flow meter pre-installed for the research on ship, and ship position (Lon, Lat), speed (SOG) data were acquired from AIS and mobile phone, and ocean environmental data was used grid-type data generated by Korea Operational Oceanographic System (KOOS). As a result of daily correlation analysis, SOG was the greatest influence on FOC. Current velocity had the greatest effect on FOC according to the stronger external force by correlation analysis of average filtering condition. When receiving external force from the ship s heading, Wind speed was derived the highest rate of change in FOC compared to the maximum correlation coefficient of daily analysis. Current velocity was analyzed to have a high effect on FOC at low ship speed (6~7kts), and wind velocity was analyzed to be correlated with FOC at high ship speed (10kts), and wave affected FOC at all ship speed. wind velocity was found to have the greatest influence on the FOC during Maneuvering, and the correlation of wave force was analyzed to be the highest correlation during Cruising. In addition, we found to save the FOC with increasing rate of SOG change to 11% according to a force of 65kg⋅f acting on ship stern. This study has a meaning in the aspect of using the results of the real ship experiment because the results were derived with the limited condition and ship type, it is necessary that supplementation research.
