Abstract

traditional fishing boats are used by fishermen for finding fish to support their daily lives. Because there are many shortcomings in their boats (design problems) and natural conditions that often change, accidents can occur which cause their boats to easily overturn and sink to the bottom of the sea. Other problems were also encountered, such as the boat's obstacles, and the boat's floating compartment was not well designed. For this reason, the author conducted research on the design of a fishing boat with a floating compartment using the BKI rules. Using one of the existing boats was made as a design reference with boat sizes. The principal dimension of the fishing boat is LOA: 10.15 m, Lwl: 8,996 m, B: 1 m, H: 0.87 m, H: 0.3 m, and 2 GT. The results of the calculations find that the engine specification that suits the fishing boat is 3.5 kW with a speed of 7 knots. The author's research varies the Floodable Length of the original boat's floating compartment with a compartment size of 1.365 m AP, 1.325 m FP, and model 2 floating compartment using BKI rules with AP size 2.225 m and FP 2.425 m. The analysis result based on the design of the fishing boat shows that model 2 is the best design. Construction in accordance with BKI regulations, a mixed type of construction was chosen. The frame distance is 500 mm with the stiffener type model h = 25 mm, bb = 30 mm, and bc = 36 mm. Meanwhile, the total stringer is 6 stiffeners.

Abstract

Efficient propeller performance contributes to better overall ship performance and speed. A well-designed propeller can optimize thrust generation, leading to improved maneuverability, responsiveness, and acceleration. It enables ships to maintain higher speeds while using less power, enhancing their competitiveness in the maritime industry. In this study, the Kaplan series propeller was analyzed by using Computational Fluid Dynamics (CFD). By modifying the angle of attack on the Kaplan propeller with 3, 4, and 5 blades, the distribution of the surface pressure, generated thrust, and torque value were easily identified and analyzed. The result shows that the change in the angle of attack influenced the pressure distribution on the back and face side of the propeller. The angle of attack is increased, and the pressure surface distribution also tends to increase. It has also affected the efficiency of the propeller performance which is expressed by the values of thrust propeller and torque. The more efficient the propeller performance, the less power it requires to produce the desired thrust.
