Abstract

Overhaul is a method of engine maintenance where the engine is dismantled and all components are checked and replaced if there is damage. In carrying out overhaul activities, engine trainer  tools are needed, therefore the operator can reach the components in the pinch point. Engine trainers on the market are usually only specific to one engine. However, in this study, a universal engine trainer was designed with various adapter arms that can rotate on one axis. This engine trainer is equipped with a buffer that is useful for reducing vibration when the engine is started. The design of the engine trainer frame was tested for strength using a static load simulation with an engine load of 400 N. The simulation showed that the frame deflection due to the load was 0.7781 mm. This value can be said to be safe from a static load test.

Abstract

This study aims to test the performance of the Batam Marine Ambulance model as a medical and logistics support fleet using the comparison ship method. A series of stability and motion analysis processes were carried out, then the results were assessed to determine the best design among the proposed design options. Performance tests used three ship models (Model I, Model II, and Model III). It is known that in the stability test, the tilt angle of model III is 33.63° and the maximum GZ value is 4.673 cm. Then, in the resistance test, Model I has a lower resistance of 87.29 N and the required power is 1496.93 W compared to the other proposed models. In the seakeeping test, Model III was found to be more stable or less affected on all surface conditions because the RAO value was relatively lower, namely 90o in terms of heaving, rolling, and pitching at 135o and 180o then had lower additional resistance. The Model III design has good ship stability, drag, and seakeeping characteristics.
