Abstract

The knowledge and skills of a ship's crew can play a key role in preventing collisions. The Bridge Watchkeeping Duty becomes crucial in this context, as they are the first to detect potential threats. Given the increasing risks in maritime transportation and the need to prevent ship collisions, several steps can be taken. One of them is to effectively carry out the tasks and functions of the Bridge Watchkeeping Duty. Therefore, this study aims to analyze the Bridge Watchkeeping Duty, specifically, the efforts to prevent sea collisions conducted by the Ship's Bridge Watchkeeping Service, and how its theoretical and practical implementation is carried out in the field. This qualitative study uses a descriptive method to describe and elaborate on the study object, namely the John Lie training ship. The study will include quotations from various data sources such as interviews, field notes, memos, and other official documents. Data analysis in this study uses the techniques of Miles and Huberman. The results of this study indicate that the implementation of these duties and responsibilities must always be based on a deep understanding of various national and international maritime regulations, as well as knowledge of the characteristics of the ship and its surrounding environment. Additionally, implementing regulations such as the 2010 Manila Amendments to the STCW 2010 is also important to ensure the welfare and fitness of the watchkeepers so they can perform their duties and responsibilities optimally. This study has several limitations, such as variables that need to be explored further, such as the psychological aspects of bridge watchkeepers who bear a heavy workload, extreme sea weather conditions, and ship facilities that support collision prevention activities. Thus, this study is expected to provide constructive thoughts and suggestions for maritime transportation stakeholders, particularly sailors and crew members, regarding the importance of properly implementing the Bridge Watchkeeping Duty. Focus on the human aspect in preventing ship collisions at sea through the Ship's Bridge Watchkeeping Service.

Abstract

Over time, marine building technology has experienced very significant developments and there are several variations of improvements that can be made to suit needs and conditions. A ship's propeller is a ship component that often experiences collisions with hard objects floating in the water which can cause the blades of the propeller to experience damage such as bending, cracking or breaking. In this case, the propeller should be repaired immediately so as not to disrupt the smooth operation of the ship. Repairing broken propeller blades can be done using a welding process. Welding is a technique of joining metals by melting part of the parent metal and filler metal with or without additional metal and producing continuous metal. Underwater Welding is a welding process that occurs in wet conditions, meaning that the electrode and object are in direct contact with air, while Gas Tungsten Arc Welding (GTAW) is an electric arc welding process that uses an untreated electrode that does not melt. This research was conducted to analyze the welding measurement results of Gas Tungsten Arc Welding (GTAW) and Underwater Welding on brass materials. To support the analysis process, testing activities are carried out including tensile tests (tensile test), hardness tests (hardness test) and macrographic observations on the results of welding materials.

Abstract

Sea waves are the movement of sea water on the surface with an up or down motion that is shaped the same as a sinusoidal line, which can arise due to the generating force on the sea surface with various types of sea wave generation by the wind, the attractive force between the earth, the moon and the sun, earthquakes and finally by the movement of the ship. Regular waves were tested in a wave flume 25 m long, 1 m wide and 1.2 m deep equipped with a flap type wave generator. The wave absorber at the other end is built from a mound of rock. Eight wave measuring points (HR Wallingford 8 channels) are co-located with the wavelength. Wave probes 1-5 are set at 0.1L while 5-8 are set at 0.2L. The wave generator then produces fluctuations in the water level that increase until it reaches the desired wave height. After several incoming waves, the reflected waves then lower the fluctuations in the water level until they reach a stable wave condition (which has the same shape and peak height) which indicates that the resulting waves are linear waves. The R2 method is used to evaluate the accuracy of wave measurement, that the two-point method with a wave measuring distance of 0.2L is the best method for measuring wave height. The two methods are compared with the general method to obtain the appropriate one for each case. The generated waves tend to be nonlinear with increasing wave height. The accuracy is reduced due to the nonlinearity of the resulting waves. Wave generator performance can be improved by reducing wave reflection. There is an influence of the distance of the wave meter on the accuracy of the wave height measurement. Good accuracy can be achieved at a wave probe distance of 0.2L for the two-point and three-point methods.

Abstract

On a Ship seasickness (motion sickness) is a condition caused by the movement of a ship that results in dizziness, nausea, and vomiting. The Motion Sickness Incidence (MSI) Study on the Patrol Catamaran (KAL-28) aims to evaluate the comfort level of passengers and the safety of the ship's crew during operations, following the ISO 2631/1997 standards. The evaluation is conducted on the vertical acceleration response of the ship under various wave conditions, speeds, and wave directions. Mapping is performed in various areas of the ship, including the deck, navigation room, and engine room, considering wave heights of 0.875 meters and 2 meters at speeds of 15 knots, 22.5 knots, and 30 knots. The research results indicate that at a speed of 15 knots, the deck area, navigation room, and engine room meet the criteria from comfortable to somewhat uncomfortable. However, at speeds of 22.5 knots and 30 knots, these areas are rated as somewhat uncomfortable to very uncomfortable. This study emphasizes the need for ship design that considers both passenger comfort and safety, especially for patrol catamarans.

Abstract

Breakwater is a very effective wave dampening building to be used as a coastal protection against coastal abrasion by destroying wave energy before it reaches the coast. The working mechanism of the OWC type is the rise and fall of ocean waves which will push the air in the OWC column, then will rotate the turbine connected to the generator to produce electricity. This study aims to determine the effect of slope and opening height on breakwater on wave reflection. Then analyze the parameters that affect the amount of wave reflection and compare the resulting wave parameters. This research was conducted at the Hydraulics Laboratory, Department of Civil Engineering, Faculty of Engineering, Hasanuddin University. The method used was experimental based. The resulting wave characteristics consist of three depth variations, three period variations and three stroke variations. The research model used is an Oscillating Water Column (OWC) type breakwater with slope variations of 45°, 60° and 90° and open wall variations as high as 5 cm, 10 cm and 15 cm. The reading of the water level fluctuation is done electronically through the reading of the wave monitor. The results showed that the magnitude of the reflection coefficient is influenced by structural parameters, namely the slope and height of the model opening and hydraulic parameters, namely depth, period and wave height. The effect of the model slope on the reflection coefficient is that the greater the slope, the greater the reflection coefficient value. The effect of the model opening height is that the greater the opening height, the smaller the reflection coefficient value.

Abstract

Indonesia is a country whose territory consists mostly of waters and islands, to support the health sector, especially for remote and inland areas and disaster emergency response activities, a means of transportation is needed that can cover and serve the area, one of which is the Hospital Auxiliary Ship (BRS). This ship is equipped with hospital facilities and infrastructure equivalent to a Type C Hospital. In its operation, the ship cannot be separated from mooring activities, therefore, the existence of a windlass as a supporting facility for lowering anchor activities is important. The windlass foundation must have optimal strength and efficiency by taking into account the reference or class as the standard used. With these considerations, this research was conducted to determine the optimality of the windlass foundation used by the Hospital Auxiliary Ship, by analyzing the maximum stress value, maximum deflection, and safety factor using the Finite Element Method. The analysis is carried out by providing load variations, namely ship loads and environmental loads. The simulation results will be compared with the calculation results based on Lloyd's Register Rules and Regulation and Biro Klasifikasi Indonesia (BKI) regulations. Reviewing the simulation results due to ship loads and environmental loads when the windlass angle is 0o, the maximum stress is 25.56 MPa, the maximum deflection is 0.01366 mm, and the safety factor is 7.81. Meanwhile, when the windlass angle is 25o, the maximum stress is 23.29 MPa, the maximum deflection is 0.01346 mm, and the safety factor is 8.58. Based on the results of calculations and analysis, it is concluded that several criteria with several angular positions formed by the windlass before and during operation still meet the criteria set by Lloyd's Register Rules and Regulation and Biro Klasifikasi Indonesia.
