Abstract

The use of fossil fuels is becoming increasingly expensive, and the amount is limited. Utilizing wind and solar energy sources onboard fishing vessels during operation is one of the solutions to reduce operational costs. This article presents a study on applying solar photovoltaic (PV) and wind turbines for a 14-meter BSC (Blue Swimming Crab) fishing vessel in Rembang Regency, Indonesia. This study discusses the use of renewable energy sources that can be applied to meet onboard electricity needs and their economic impact. This analysis considers to operating system scenario for seven days catching the BSC in the Java Sea. The calculation results show that the solar PV and wind turbine energy that can be utilized as electrical energy are 22,960-Watt h. The required battery is 20 units at 100 Ah 12 Volts and an investment cost of USD 21,084. The advantage of applying this technology is an operational cost saving of 16%, which can increase fishermen’s income by 11%. The challenge of a hybrid or electric propulsion system is fantastic, using the serial configuration of the power topology, and the result of preliminary estimates of the investment value is approximately 173,277 USD.

Abstract

Mandakini Neo was made with the ship's capacity, speed, and comfort in mind, as well as the ship's hydrodynamic performance and construction cost. Therefore, the method used to determine the hydrostatic characteristics is through a simulation consisting of a resistance test, stability test, maneuver test, and seakeeping test. The simulation uses Maxsurf software with the Savitsky method, which is then processed by data. Global Positioning System (GPS) and ultrasonic sensor tests were also conducted. Based on the simulation results, the stability of the Mandakini Neo ship has a GZ value of 0.1417 m with an angle of 30°, which follows the standards of the International Maritime Organization (IMO). In testing, the maneuvers obtained have met IMO standards based on tactical and advanced diameters. Based on the seakeeping test, when the speed is 5 knots, the heave movement has the same magnitude for all wave headings, 0.0096 m. while the most considerable rolling motion is in the wave direction of 135°, which is 0.36 m, and the most considerable pitch motion is in the direction of the 180° wave, which is 0.042 m. At a speed of 10 knots, the heave motion produced is the same as for all wave headings.
