Abstract

Peningkatan efisiensi energi pada kapal menjadi isu penting seiring dengan diberlakukannya regulasi pengurangan emisi gas rumah kaca oleh International Maritime Organization (IMO). Salah satu solusi yang dapat diterapkan adalah penggunaan Energy Saving Device (ESD), seperti vortex generator (VG), yang berfungsi mengendalikan aliran fluida di sekitar buritan kapal. Penelitian ini bertujuan untuk menganalisis pengaruh pemasangan delta vortex generator terhadap pengurangan tahanan total kapal dan peningkatan performa propeller menggunakan metode Computational Fluid Dynamics (CFD). Objek penelitian yang digunakan adalah KRISO Container Ship (KCS) berskala 1:31,6 dengan propeller KP505. Simulasi dilakukan melalui resistance test, open-water test, dan self-propulsion test pada kondisi tanpa vortex generator dan dua konfigurasi vortex generator. Analisis difokuskan pada parameter tahanan total kapal, gaya dorong, dan torsi propeller pada kecepatan servis sebesar 4,269 knot. Hasil simulasi menunjukkan bahwa pemasangan VG mampu menurunkan tahanan total kapal secara konsisten. Pada kecepatan servis 4,269 knot, tahanan total kapal berkurang dari 81,760 N pada kondisi bare hull menjadi 78,059 N atau sebesar 4,527% untuk konfigurasi pertama, dan menjadi 78,900 N atau sebesar 3,498% untuk konfigurasi kedua. Selain itu, hasil self-propulsion test menunjukkan peningkatan gaya dorong propeller dari 60,095 N pada kondisi tanpa VG menjadi 60,880 N dan 61,377 N untuk masing-masing konfigurasi. Pada konfigurasi pertama, peningkatan gaya dorong diikuti dengan penurunan torsi dari 2,577 Nm menjadi 2,512 Nm, yang mengindikasikan peningkatan efisiensi propeller. Berdasarkan hasil tersebut, dapat disimpulkan bahwa pemasangan delta VG efektif dalam mengurangi tahanan total kapal dan meningkatkan performa propeller, dengan konfigurasi vortex generator pertama memberikan kinerja paling optimal dalam penelitian ini.

Improving ship energy efficiency has become a critical issue following the implementation of greenhouse gas emission reduction regulations by the International Maritime Organization (IMO). One solution that can be applied is the use of an Energy Saving Device (ESD), such as a vortex generator (VG), which functions to control the fluid flow around the stern of a ship. This study aims to analyze the effect of installing a delta vortex generator on reducing total ship resistance and improving propeller performance using the Computational Fluid Dynamics (CFD) method. The object of this study is the KRISO Container Ship (KCS) at a scale of 1:31.6, equipped with a KP505 propeller. The simulations were conducted through resistance tests, open water tests, and self-propulsion tests under conditions without vortex generators and with two vortex generator configurations of different sizes. The analysis focused on total ship resistance, propeller thrust, and torque at the ship’s service speed of 4.269 knots. The simulation results indicate that the installation of vortex generators consistently reduces the total ship resistance. At the service speed of 4.269 knots, the total resistance decreased from 81.760 N under bare hull conditions to 78.059 N, representing a reduction of 4.527% for the first configuration, and to 78.900 N, corresponding to a reduction of 3.498% for the second configuration. Furthermore, the self-propulsion test results show an increase in propeller thrust from 60.095 N without vortex generators to 60.880 N and 61.377 N for the first and second configurations, respectively. In the first configuration, the increase in thrust was accompanied by a reduction in propeller torque from 2.577 Nm to 2.512 Nm, indicating an improvement in propeller operating efficiency. Based on these results, it can be concluded that the installation of delta vortex generators is effective in reducing total ship resistance and improving propeller performance, with the first vortex generator configuration providing the most optimal overall performance in this study.
