Abstract

One of the phenomenon appears on operation of marine propeller is noise. It could reduce performance of the propeller. In this study, numerical simulation is used to predict hydrodynamic performance and noise around non cavitation propellers. The formulation of RANS (Reynold Averaged Naiver Stokes) with turbulence model k-ω SST (Shear Stress Transport) and FWH (Ffowcs Williams–Hawkings formulation) is applied on the simulation. The noise is expressed in time-domain acoustic analogy as well as finite volume, and it is predicted at different receiver positions. The performance of propeller is predicted by MRF technique (Multiple Reference Frame). The 3D model of B-series propeller with diameter of D = 250 mm, blade number Z = 4, pitch diameter ratio P/D = 1, and area ratio Ae/Ao = 0.55 is simulated on various advance coefficients (J). Propeller rotation is simulated in range of 7.5 rps - 29rps and Re = 6.95x104– 3.36x106

Abstract

Biaya kebutuhan bahan bakar di kapal merupakan komponen yang tertinggi dalam pengoperasian kapal. Salah satu upaya untuk mengurangi biaya kebutuhan bahan bakar ini adalah dengan menggunakan alternatif bahan bakar gas. Selain itu dapat menghemat biaya operasional kapal, penggunaan gas sebagai bahan bakar juga dapat mengurangi emisi kapal. Studi ini bertujuan untuk mengkaji pengggunaan gas bumi menjadi bahan bakar di kapal dengan cara modifikasi sistem untuk fuel system kemudian menentukan lokasi bunkering LNG dan skema pengisian bahan bakar (bunkering) LNG. Analisis penentuan lokasi bunkering dilakukan dengan metode Greedy Random Search untuk mencoba semua alternatif dari semua variabel kemungkinan (possible variable). Hasil dari modifikasi adalah dengan menambahkan gas transfer dari replace menuju ke main engine meliputi LNG Replace, LNG Cryogenic Pump, Heat Exchanger, Gas Valve Unit (GVU), dan Conversion System. Pemilihan skema bunkering menggunakan pembobotan dengan metode Analytical Hierarchy Process (AHP). Alternatif lokasi bunkering yang terpilih adalah di pelabuhan Merak, Pelabuhan Ketapang Pelabuhan Lembar, Pelabuhan di Makassar, Pelabuhan di Surabaya, Pelabuhan di Sorong, Pelabuhan di Ambon, Pelabuhan di Semarang, Pelabuhan di Jakarta, dan Pelabuhan di Jayapura. Skema bunkering LNG yang dipakai pada setiap pelabuhan adalah Truck to Ship, sesuai dengan opsi yang terpilih
