Desain Sistem Penggerak Dari Single Screw Menjadi Twin Screw Pada Kapal Motor Penyeberangan 1325 GT
Regulation of the Minister of Transportation of the Republic of Indonesia no.104 of 2017 article 1 paragraph 4 concerning the implementation of ferry transportation which reads Ferry Motor Ship which requires two main engines on the Ferry Motor Ship, then a replacement is made from using one main engine which is then changed to using two main engines which can be used by the ship owner as a consideration for changes made. Therefore, the design of the drive system designed for the use of twin screw propellers, in order to obtain the results of the consideration that begins by calculating the resistance with a result of 30.026 kN, then the main engine will be selected to be used, because the new design uses Twin Screw Propeller. must be recalculated using the Engine Propeller Matching method after the matching is complete, then it is necessary to continue designing the drive system with the design of the engine foundation and its supporting system. Then the design of the propulsion system is carried out by planning the strut because of the shaft that penetrates the hull that is too long, after all is designed, a simulation is carried out on the ANSYS Workbrench software with 3D modeling on the ship to determine the thrust value when the ship uses single screw when using twin. screw. At this simulation stage the thrust on the twin screw propeller shows a value of 35.6484 kN, while the simulation on the single screw propeller shows a value of 30.2658 kN..
