Design of portable floating battery platform utilizing solar and wind energy sources

Abstract Overfishing is caused by excessive fishing, resulting in a significant decrease in fish populations. This has a detrimental impact on marine ecosystems, fish availability, and fishermen’s income. Since 2008, the fishing area in the Madura Strait has experienced overfishing. In relation to the many fishing areas in Indonesia that have experienced overfishing, Government Regulation No. 11 of 2023 was issued on controlled and proportional fishing, carried out in measured fishing zones, based on fishing quotas to preserve fish resources and their environment, and equalize national economic growth. From the perspective of a Marine Engineer, one method to implement this government policy is by changing from fuel to batteries on fishing boats, as well as building energy stations throughout the waters of the Madura Strait. Therefore, this research aims to design a floating energy station based on solar panels and wind turbines to cover the needs of four 10 GT fishing boats with a battery capacity of 90 kWh. Based on numerical methods and trial and error according to weather data, the floating energy station uses 135 solar panels of 550 Wp and 16 wind turbines of 2 kW used to charge 300 batteries of 24 Volts, 100Ah. All batteries can be recharged in 8.5 hours.
