METHODOLOGY OF THE HYBRID PROPULSION SYSTEM (DMP & DEP) FOR TRIMARAN TYPE FAST Patrol Boat
Diponegoro University, 2012Co-Authors: Aulia Widyandari, Dedy WahyudiAbstract:There are lot of research done to develop a Patrol Boat, from the modification of hull model until propulsion system equipment. For example the model ship type AMV (Advanced Marine Vehicle) was developed starting from the Catamaran, Trimaran and Pentamaran model. Everything is aimed at obtaining the ship design that has the speed and stability. In addition to achieving high-speed vessel must be equipped with propulsion (Main Power) is great, that means the main engine dimensions, auxiliary equipments and fuel tanks is too large. Many Limitations of space on the ship's engine room trimaran vessel is the main obstacle in designing propulsion system. Beside that Patrol Boat should have many missions speed, so propulsion system should be designed at that conditions. Hybrid propulsion is a combination of Diesel Mechanical Propulsion (DMP) with Diesel Electric Propulsion (DEP). DMP system is connected directly to the propeller shaft (or through a reduction-gear). DMP has provide more efficiency rate of 95%. While DEP is only able to provide efficiency by 85% - 89% is slightly lower than DMP, but the DEP offers many advantages such as simplicity and suitability in the rotational speed settings, control systems, engine power production Redundancy, Flexibility in the design of equipments layout in engine rooms, noise, vibration and fuel consumption efficiency which affects the lower pollution. Design of Hybrid Propulsion system can be satisfied and achieved the Power requirements and optimally at all speed condition of Patrol Boat. Therefore the author made using modeling Maxsurf-11.12 software and carried out various optimization of the choice of main engine, propeller and system conditions for fast Patrol Boat cruise.

analysis of the roll decay motion for a Patrol Boat by urans simulations
ASME 2009 28th International Conference on Ocean Offshore and Arctic Engineering, 2009Co-Authors: Riccardo Broglia, Roberto Muscari, Andrea Di MascioAbstract:The simulations of the flow around a vessel of the Italian Navy in free roll decay have been carried out by the numerical solution of the Reynolds Averaged Navier-Stokes equations. The focus is on the analysis of the roll motion coefficients (damping and period of oscillations) at different Froude and Reynolds numbers. To this aim, numerical simulations were carried out at three different speeds, with corresponding Froude numbers equal to 0.160, 0.227 and 0.337, and Reynolds numbers ranging from 4.073 106 to 1.300 107 at model scale. Computations were carried out by means of an in-house unsteady RANS solver; the scheme is based on a finite volume discretization, and it is globally second order accurate. The free surface is handled by means of a suitable single phase level set algorithm; moreover, Chimera overlapping grid capabilities have been implemented in the code, which has been also efficiently parallelized. An analysis of the roll motion, longitudinal and lateral forces and roll moment is carried out for the different speeds considered. A preliminarily grid convergence analysis is also performed.Copyright © 2009 by ASME

perencanaan simulasi pengaturan pembangkitan daya pada kapal fast Patrol Boat 60 m dengan propulsi hybrid
Jurnal Teknik ITS, 2017Co-Authors: Fikri Nuruddin Muzakki, Eddy Setyo Koenhardono, Adi KurniawanAbstract:Sistem propulsi hybrid yang memberikan berbagai keuntungan untuk pengoperasian kapal, seperti pertimbangan konsumsi bahan bakar yang rendah, pengaturan kecepatan dengan penggunaan propulsi yang optimal ataupun khusus untuk jenis kapal tertentu. Tentunya sistem propulsi hybrid memiliki kelamahan pula, salah satunya adalah pengaturan pembangkitan daya yang kompleks dibandingkan dengan system propulsi lain. Setiap kecepatan membutuhkan daya yang berbeda dan bahan bakar yang berbeda pula. Keputusan yang kurang tepat dapat mengurangi keunggulan dari pemasangan sistem propulsi hybrid. Oleh karena itu dibutuhkan Decision Support System untuk membantu nahkoda menentukan pengaturan propulsi yang optimal pada kecepatan yang diinginkan dan pada kondisi yang ada pada perairan yang dilalui. Dalam makalah ini dibuat Decision Support System dengan input utama berupa kecepatan dalam knot, service margin, dan kebutuhan listrik. Kecepatan dan sevice margin digunakan untuk menentukan kebutuhan tenaga penggerak dan selanjutnya digunakan untuk analisa alat penggerak. Untuk digunakan referensi nahkoda dapat memilih propulsi yang optimal dengan konsumsi bahan bakar yang minimum, dan dengan jumlah daya yang diperlukan untuk pengoperaian tersebut. Berdasarkan hasil simulasi penggunaan Decision Support System pada kapal Fast Patrol Boat 60 m ini menujukkan pemakaian terbaik pada kecepatan 20 knot dengan menggunakan sistem Shaft Generator pada daya 1181 kW disertai pengoperasian genset pada daya 0 kW dan jumlah pemakaian bahan bakar 482,99 kg per jam.
