Abstract

Shipbuilding nearly 2/3 of the work is welding work. There are several variations of the weld joint as an option based on the thickness and quality of the material, the method of welding. Welding results generally depend heavily on the skill of the welder. Weld damage both on the surface and on the inside is difficult to detect with a simple test method. In addition, because the structure being welded is an integral part of the entire body of the weld material, the cracks that arise will spread quickly and may even cause serious accidents. In general, welding on ships has requirements from the Classification Agency which supervises and provides the feasibility of the ship's construction strength. To meet these requirements, the role of the welder and technique is very large, so that the ship gets good welding quality and can be accepted by the shipowner and the classification agency.

Abstract

Tank is a cargo storage container and is the main part of ships carrying liquids and gases so that the cargo is maintained and safe. As a storage medium, the tank will always get loads that come from inside as well as loads that come from outside the tank, sloshing is one of the loads that come from inside. Sloshing occurs due to the movement of the vessel/tank resulting in free motion of oscillating fluid hitting the tank wall. The purpose of this study was to find the effect of the load on the movement and sloshing load on the tank with variations in the amount of load. The tank model used is a reference to a general purpose tanker transporting crude oil in two-dimensional rectangular conditions (midship) with a width of 8,6 m and a height of 8 m on both the left and right sides. The variations used are 10% load volume (0,8 m high), 30% volume (2,4 m high), 50% volume (4 m high), 70% variation (5,6 m high) and 90% variation (high 7,8 m). The simulation was carried out with a numerical method, namely Computational Fluid Dynamic (CFD) using Ansys Fluent software. The back of the tank is based on the movement of the ship which in this case is limited to heaving and rolling motion, from the simulation results it is concluded that the biggest sloshing effect occurs at the load volume variation of 10%, the frequency is 2.145, while the greatest pressure occurs at the lower left corner of the tank with a pressure of 443,29 Kpa.

Abstract

The diesel engine as the main engine on the ship can function properly if it is supported by good supporting systems such as a lubricating oil system. The lubricant system is one of the most important systems in ship operation, failure in the lubrication system causes the system to not operate properly and can suffer losses from the ship. This study aims to determine the failure of each component of the lubricating system in the main engine and its proper maintenance. This study was conducted using the Failure Mode and Effect Analysis (FMEA) method to optimize the way to overcome the failure and maintenance of the ship's main engines to identify strategies and maintenance priorities. By using FMEA, we can determine the failure and the effect caused by each component and to perform maintenance must classify components based on low to high risk levels. The components of lubricating oil tank and sump tank have a low risk, lubricating oil cooler has a moderate risk and lubricating oil pump, lubricating oil filter, purifier, transfer pump and lubricating purifier heater have a high risk. The results of the failure of lubricant system components are very useful in identifying maintenance strategies based on the level of risk of these components by choosing between preventive maintenance and corrective maintenance.

Abstract

This article discusses the worker's safety assessment of the loading and unloading process that causes cargo product defects at Paotere Harbour. Makassar, which is the capital of South Sulawesi province, is known as the city with the largest majority population and is a dense flow of inter-island freight traffic. One of the Harbours that transportation the economy in Makassar is the Harbour of Paotere which provides dock services for fishing boats, passenger ships and cargo ships. Phinisi motor sailing ships are equipped with lifting equipment, namely cranes that can lift goods to facilitate the loading and unloading process of goods from the ship to the edge of the pier. However, the loading and unloading process ignores the safety and health aspects of work on the deck of the ship and on the dock. In addition, the results of the products being trans Harboured must also be considered if someone experiences product defects due to loading and unloading activities at the Harbour of Paotere. J-hook, a tool used to lift and move the sack by stabbing it in any place, can cause the sack to tear and the grain inside will slowly spill out due to gaps in the sack. The method used in this research is the descriptive method, namely: providing an overview of certain phenomena or certain aspects of the location under study. Descriptive methods are not only limited to data collection but include direct observation and interviews with workers. The strategic solution needed is the replacement of the cargo lift knot rope on the crane with a mooring rope net that facilitates the lifting process from the ship's deck to the Paotere Harbor pier. Replacing the J-hook whose function is to shift and flip the sack with an enlarged Jar Lifter tool and an adjustment of the material that is comfortable to hold and is not dangerous if it falls and hits the limbs of workers who are carrying out loading and unloading activities Paotere Harbor.

Abstract

Indonesia has a sea area of ​​96,079 km2 and a coastline of 99,093 km, making Indonesia has the potential to utilize the sea as a new and renewable energy source. However, the use of new and renewable energy has only reached 6.2% in 2015. One of the marine energies that can be utilized is ocean currents. Awerange Bay, located in South Sulawesi, is a point that has a source of marine energy and can be used as an environmentally friendly, sustainable renewable energy. The current velocity in the Awerange Bay area in low tide can reach 0.25 - 0.36 m / s. So it can be possible to use tidal energy using turbines. The Kobold turbines take advantage of currents from seawater in Awerange Bay. By using a bi-directional (two-way) turbine that moves the turbine clockwise or vice versa. Turbines that are installed horizontally on the seabed can convert the kinetic energy of the turbines into electrical energy during tides, making the turbines suitable for use as marine tidal power generation. As a sample based on the Ministry of Energy and Mineral Resources, current energy can produce 1.2 MW / turbine. The big advantage of bi-directional turbines is that the propeller blades do not need to be reversed when the flow direction changes. This makes for a robust design, less expensive to build, maintain, and a lower risk of breakage. Also two-way turbines on average produce twice the electrical energy that uni-directional turbines, which only function during tides or floods.
