Abstract

A ship is a floating Structure that moves and is used in water ttransportation, to good manouvering, and to get a certain speed with propulsion efficiency, ship hull is commonly streamlined and designed so that obstacles or frictional forces with water are small, streamline forms in general the shape follows the flow of fluid or water so that the shape of the hull is curved. With a curved shape, the shape of the room inside also follows the hull of the ship, as well as the shape of the fuel tank, lubricant tank , fresh water tanks, liquid cargoes are also curved / curved or not square, tubes that are easy to determine volume. This volume calculation needs to be done carefully because it involves the need for fuel, fresh water, lubricants that will be needed during the trip in order to ensure that the needs are fulfilled until the destination. There are several methods for determining the area and volume of a curved plane, such as trapezium, simson etc. In carrying out measurements, students often have difficulty in understanding the method of measuring the area and volume of curved spaces on the ship, so it is necessary to make a real model, From the experimental results, it is known that for Samson's rule 1 there is a volume difference of almost 8%, for Samson II's rule it is 6%.

Abstract

The ship as a transportation at sea musthave the safety requirements issued by the competent authority. Extreme environments, and machine operations that run 24 hours non-stop must have a high level of reliability. Good and proper maintenance will make the ship's life long and provide economic value. Several tools to perform risk analysis are FMEA, as a tool for qualitative analysis can be used as a reference in carrying out maintenance and as a tool that makes it easier for crews to carry out analysis and maintenance to prevent failure. In this case study, it can be concluded that the activities carried out by the crew are in accordance with what the FMEA table has compiled, and it is proven that even though the ship is more than 30 years old, it is still operating normally. This can be seen from the KM Mitra Papua logbook.
