The development of ship always searches through the most benefits system for reducing costs of propulsion system without increase pollution. Diesel propulsion system or also known as conventional propulsion system is efficient but requires high operating costs and increase high level of marine pollution. Electrical propulsion system is using electric motors as the prime mover of the propeller. There are 2 types of electric motors that will be used for research of electric propulsion system, there are; DC motors and three-phases induction motor. As the use of DC motor as a prime mover for this electrical propulsion system, this study determines the characteristic between voltage terminal with torque and also field current with torque. It results that torque produced by the DC motor is in the same magnitude with the speed (RPM). The higher the speed have shaped the value of the torque. The input and terminal voltages adjusts all variables and results. In this study, different field voltage creates different pattern of motor envelope. Its manner to propeller curve occurs total different results. With field voltage of 50 V, the ranges of motor envelope immoveable in the point of 150% of present speed and 160%. While field voltage of 60 V serves larger ranges of motor envelope which possible to reach further than 50 V curve.

Analysis of the Requirement for the Ships Using Methanol as Fuel Michael Rachow; Steffen Loest; Agus Dwy Bramastha

Methanol is a safe, cost-effective alternative marine fuel. It is one of promised solution for being shipping fuel because of it feedstock and produces less pollution than fossil fuel. Methanol is one of new fuel in the shipping industry; because of that there are lack of regulation for this fuel. IMO has not release regulation of using methanol as fuel but there is some draft is in process. The document that can be found to represent the draft of IMO IGF Code is report of Sub-Committee of Carriage Cargo and Containers (CCC) 3-3. Classification society that has the regulation for using methanol is LR and DNV GL. Comparing the three regulations and selecting the regulation that has high safety level is the best way to design the methanol-fueled ship. The result shows that there still some different opinion on the three regulations that regulate the methanol as ship fuel. Some regulation also doesn’t mention about the detail material that should be use in the system. Calculation method to selecting pipes thickness also different. To make it safe, the thick one should be used. Implementation the regulation on board ship resulting loses the payload of their cargo. The specific fuel consumption will be increased by factor 46% compared to fuel oil SFOC and the storage tank shall be protected by cofferdam that takes a lot of space. To safe ships space the service tank is recommended put in the main deck to prevent the use of protective cofferdam.
