Abstract

The diesel engine is a vital component that serves as the ship's main propulsion system. This engine plays a crucial role in the efficiency and operational stability of the ship. One of the important parts of a diesel engine is the governor, which functions to regulate the engine's rotational speed to keep it stable. Problems with the governor can cause engine speed instability, leading to operational issues, reduced fuel efficiency, and a higher risk of damage. The study uses observational methods to identify the main causes of engine speed instability due to governor failure. Basic data include measurements and observations, maintenance history, and records of past failures. Observations on engine speed instability caused by governor failure focus on electrical issues, material wear, and extreme temperatures. This research emphasizes the importance of good and routine maintenance for the governor. Maintenance includes regular inspections, electrical maintenance, and the replacement of worn components. The research results are expected to provide practical recommendations for ship technicians to improve maintenance activities and address diesel engine speed instability issues. Implementing the findings of this research is expected to enhance the overall safety and operational efficiency of the ship

Abstract

A refrigeration machine is a device used to transfer heat from indoors to outdoors to make the temperature of the room lower with the aim of cooling/preserving food. Cooling machines on MT ships. Kuang, when the ship was sailing, experienced that the optimal temperature was not reached, so it was necessary to observe this problem. So that action can be taken so that similar problems can be resolved and do not happen again. This research is based on a case study conducted on the MT ship. Kuang. The method that the author uses in collecting data is the observation method, namely a data collection method by making direct observations of the research object, an interview method with the author communicating with technicians regarding the problem being handled, as well as a literature study method, namely collecting references contained in relevant books, journals and studies. Approach to problem analysis using a qualitative descriptive method. From the results of the discussion carried out by the author, it is known that the optimal temperature was not achieved due to freon leaks in the evaporator pipe, dirty oil separator, dirty condenser and sea chest, and the cooling machine door not being tight. This is the impact of lack of maintenance on the cooling machine (refrigerator) and the cooling machine is quite old.

Abstract

The objectives discussed in this paper are to answer the questions in the subject matter, namely to increase understanding of safety equipment, especially fire fighting equipment. So that it can optimize its performance. Increase the level of readiness of fire extinguishers so that whenever and whenever fire extinguishers have to be used they will be maximally used. OHS officers are people who work with the task of occupational health and safety as well as operating and maintaining fire extinguishers so that fires can be prevented. Where the duties and responsibilities must be carried out and accounted for properly according to orders from the leadership of the company. Fire extinguishers are one of the countermeasures and minimize the occurrence of fire hazards. So the role of fire extinguishers is very important, fire fighting is an action that must be taken to create a safe and efficient work environment. Skills include knowledge of fire extinguishers and the responsibilities that must be carried out. Therefore, it is very necessary to improve the skills of OHS officers, namely by increasing the material for the discussion of fire extinguishers, carrying out fire extinguishing exercises and maintaining and checking fire extinguishers.

Abstract

The case study on the tugboat award 1 experienced problems with the propeller which made it possible to be out of balance. The purpose of this research is to find out the causes of unbalanced propellers on ships and how to overcome them. The use of research methods using observation, interviews and data analysis by observing, reviewing and analyzing objects or problems that will be examined directly so that the data obtained is objective because the author experienced it himself and was at the ship docking location when the work of the propeller was not perfect. From the data obtained, then an analysis of descriptive qualitative methods was carried out. The results of this study state that the unbalanced propeller is caused by fouling, erosion, cracks, and deformation of the propeller blades. Possible triggering factors include long absence of maintenance, old components, and negligence in operation. An unbalanced propeller if not handled immediately is feared to cause damage to other components such as damage to the stern tube which results in leaks and can endanger the ship.
