Optimization of B-series propeller geometry dimension to improve traditional fishing ship performance

Abstract

The fishing ship propulsion system will affect the performance of the ship and impact the fishermen’s income. A crucial factor is the level of efficiency produced by propellers mounted on fishing vessels. In B-series propellers, propeller efficiency can be optimized by varying the size of the geometric dimensions. This propeller optimization process can be done after the ship resistance value is known. In Cirebon waters, as in other regions in Indonesia, the selection of propellers by fishermen is still unclear. Most are only based on the availability of goods on the market, without looking at how big the actual ship resistance occurs. In this research, one of the fishing boats that will be built will be chosen to estimate the ships’ resistance. After that, by considering the engine used as its driving source, the geometry dimensions that can produce the highest efficiency are sought. Estimation of ship resistance is sought by the Holtrop method, and propeller optimization is carried out with the help of software. From the results of this study, the value of ship resistance commonly used by Cirebon waters fishermen is 2.608 kN at an operational speed of 7 knots. Optimized propeller design provides a 6 percent increase in efficiency compared to previously used propellers.

A Propulsion System Design Methodology Based on Overall Efficiency Optimization for Electrically Powered Vessels

“…In the work of Windyandari et al (2018), a procedure to determine the optimum design parameters for a B-series propeller is presented, therefore improving the vessel performance. Similarly, Mulyana et al (2020), presented also a methodology to optimize the efficiency of a B-series propeller for a known value of the hydrodynamic resistance. Since in this work the case of study was a fishing vessel, for which it is not usual to make a proper sizing for the selection of the propellers rather than to opt for those available in the market, the authors verified that by selecting the optimal propeller instead an increase of 6% in the total efficiency of the vessel can be obtained.…”

Computational Comparison of AC and DC Motors to Hydrodynamic Changes in Marine Fishing Vessels

“…For this, changes in the hydrodynamic behavior are modeled in the Maxsurf software in different wave and swell conditions, with roll, pitch, and yaw movements. To select the propeller, it is taken into account that a vessel for fishing applications has distinctive characteristics in speed, maneuvering, construction, and storage [24]. The propulsion system assembly must have a large pulling capacity, for this reason, a 3-bladed propeller is selected as done in [24], [25].…”
