Loading and unloading of containers from ship to the quay at the container terminal is a high risk activity that has high potential of creating accidents both to human as well as to property. The study is aimed to conduct safety assessment that can be used further for minimising work accidents at the port. Hazard Identification and Risk Assessment (HIRA) method is used to identify the type, cause, and effect of the potential risks based on the activity sequences. A risk matrix is arranged for obtaining the risk level. Root cause of the highest risk activity is investigated using Fault Tree Analysis (FTA) method. 5 potential risks are identified i.e. worker slips, trips or falls; truck struck by quay crane, worker struck by truck, worker struck by falling hatch cover or container, and worker trapped between containers. The root causes of potential accidents are human fault, equipment maintenance, and environment.

In order to introduce clean environment and sustainable energy to traditional coastal fishing community, the objective of this study is to encourage the Indonesian traditional coastal fishing community to use green and renewable energy in their fishing activities. Introducing solar power as the main source of energy for fish-attracting lights and boat propulsion can reduce the use of fossil fuels, and sustain clean and healthy environment. As the world’s largest archipelago, Indonesia accounts for a high percentage of traditional fishing communities spread out along its islands. This fishing communities use various traditional fishing boats, and platforms. The fishing platforms are usually made of bamboo and placed on top of supporting structures on the seabed. Diesel electric generators are used to obtain electricity needed for lighting to attract the fish at night, and as the source of power for lifting the fishing net. The structure and fuel used are neither environmentally friendly nor clean;thus, an innovation is introduced. Traditional fishing practices using a fishing platform were studied, including the common size of the platform and the power needed for the fishing light. Based on the gathered information, this study proposes a catamaran vessel with a special top structure designed for fish lifting outfitting, and equipped with photovoltaic solar cells as the energy source for the fishing lights and vessel propulsion. Through this innovative break through, the vessel can be moved to the shore and will not be a threat to ship navigation and the environment. Furthemore, powered by clean and sustainable energy, the vessel can be directed to the best fishing ground.

A planing hull high-speed ferry with a stepped hull becomes a well-liked mode of water transportation for archipelago countries. On the other hand, the shape of steps on the bottom hull has not been recently taken into explicit consideration regarding the speed requirement and hydrodynamic properties. In this study, the step W shapes, were adopted to find the improved hydrodynamic performance in the planing conditions. To provide a more precise prediction of the pressure, velocity fields, and void fraction, the CFD was applied the Finite Volume Method (FVM) and coupled with Volume of Fluid Method (VOF) to capture air cavity The numerical conditions of the planing hull were trimmed by the stern with 2, and 3 degrees. This study discussed the air cavity that occurred behind the stepped area that can affect the hydrodynamic behaviour. © 2023 by the International Society of Offshore and Polar Engineers (ISOPE).

引用

INTERNATIONAL JOURNAL OF ENGINEERING 2022年第9期35卷 1690页

作者： Tuswan, T. Sari, E. N. Ismail, A. Prabowo, A. R. Univ Diponegoro Dept Naval Architecture Semarang Indonesia Univ Billfath Dept Mech Engn Lamongan Indonesia Indonesia Def Univ Ship Machinery Study Program Belu Indonesia Univ Sebelas Maret Dept Mech Engn Surakarta Indonesia

Research on lightweight material on ship structure has taken giant steps during the last decade. One reason is that shipping activities have increased and, therefore, the possibility of increasing the carrying cargo capacity in a realistic way using advanced lightweight material. This article summarizes a research investigation regarding the experimental tests of vinyl ester bio resin material using palm oil and sesame oil based on Lloyd's Register (LR) standard. Several tests were conducted, including density, water absorption test, Fourier transformed infrared test (FTIR), scanning electron microscope (SEM), and mechanical tests to evaluate the effect of 2-10% addition of vegetable oils on mechanical properties. The influence of the addition of vegetable oils is successfully characterized using physical measurements, which indicate the possible formation of a polymer blend to increase in elongation value. Mechanical testing shows that adding vegetable oils causes a decrease in average density, hardness, bending strength, and tensile strength. The bending strength decreases about 9.20 - 47.06% for 2-10% palm oil addition and 5.33 - 42.40% for sesame oil addition. Moreover, vegetable oil causes a tensile strength decrease of about 5-18.75% on palm oil and 3.75-13.75% on sesame oil. As summarized, bio resin based on sesame oil has better mechanical behavior with the oil addition of 4-8% fulfills all Lloyd's Register criteria.

Development of an Automatic Anti Pitching System (APS) Autonomous Surface Vehicle (ASV) for Fish Mapping

引用

Journal of Physics: Conference Series 2020年第3期1569卷

作者： Noverdo Saputra Muhammad Arifudin Lukmana Purwo Joko Suranto Study Program Naval Architecture Universitas Pembangunan Nasional Veteran Jakarta Indonesia Study Program Mechanical Engineering Universitas Pembangunan Nasional Veteran Jakarta Indonesia

The common problem occurs in fish mapping using autonomous surface vehicles (ASV) is pitching stability. Some researchers have indicated that problem affects the results of mapping. The target of this system is to design an Autonomous Pitching System (APS) for ASV using numerical simulation software. The simulation is done by implement APS into the system, producing an oscillatory motion from the ASV. For both dynamics of craft in short and long periods, APS with proportional controller (P), proportional-integral controller (PI), and proportional-integral-derivative controller (PID) are developed in order to minimize the oscillatory behaviour. It was found that for the short period dynamics, the APS with PI controller was the optimal controller, followed by the PID controller and then the P controller. For the long period dynamics, the APS with PID controller was optimal.

作者： Raber, JD Perin, DA Mr. James D. Raber:received a master of science degree in naval architecture and marine engineering from the Massachusetts Institute of Technology in 1967. Since 1967 he has worked for the Navy Sea Systems Command (NAVSEA) and predecessor organizations in the area of early stage design of naval ships. Among the major USN programs he has supported are the FFG 7 and DDG 51. In the late ‘70s he was the NAVSEA representative to the CNO DDX Study Group which established the general requirements for the DDG 51 class. He has been active in international technical exchange programs for which he was awarded membership in the National Order of Merit by the Republic of France in 1992. Since early 1996 he has been the NAVSEA Ship Concept Team Leader for what is now the CVNX Program. Dr. David A. Perin:received a PhD in mathematics from the University of Michigan in 1971. He joined the Center for Naval Analyses in 1973 where he has led a wide variety of studies on naval warfare. From 1985 to 1987 he served as the CNA representative on the staff of Commander Striking Fleet Atlantic for which he was awarded a Defense Distinguished Service Medal. During the 1990s he has led formal analysis of alternatives for the LPD-17 F/A-18E/F and CVX. Currently he is the Director of the JCC(X) Analysis of Alternatives.

In March 1996, the Department of Defense established a new program, then known as CVX, to develop a new class of aircraft carrier that would eventually replace the Nimitz class. The first step in the concept develop was exploring a wide range of alternative design concepts in a formal study known as an Analysis of Alternatives (AOA), which assessed their cost and operational effectiveness. About 70 total ship studies were developed to explore the range of design features, including airwing size and type, propulsion type, ship mobility performance, and a variety of survivability features. The AOA also assessed the performance of and total ownership cost of a large number of potential subsystem technologies. This paper summarizes the total ship studies developed for the AOA describes the ship system performance and total ownership cost of these alternatives, and discusses the rationale for determining some of the primary system requirements. Thus, the paper will provide insight into the Navy's intentions for system requirements and features to be incorporated into the U.S. Navy's future aircraft carriers.

IOP Conference Series: Earth and Environmental Science 2018年第1期105卷

作者： Sunaryo Dendi Nurachman Pradhana S Imfianto Naval Architecture and Marine Engineering Study Program Department of Mechanical Engineering Universitas Indonesia Depok 16424 Indonesia

Indonesian government has a flagship program that is to promote the nation through the maritime sector and make Indonesia as Global Maritime Fulcrum. To achieve that, sea transportation is very important for the development of Indonesia. But sea transportation is also the highest contributor to the air pollution and global warming. In order to reduce the source of global warming Indonesian Government has a strategic plan to gradually replace the use of fossil energy with renewable energy. One of the renewable energy that can be used effectively in Indonesia is solar energy, because Indonesia located along the equator and has a high intensity of sunlight that means it has excellent solar energy availability. In attempt to contribute to the Government's energy strategic plan, the research is aimed to design a solar-powered electric boat with single pilot. The project is a further development of the solar boat created by the Universitas Indonesia team that participated in the International Solar-boat Challenge competition in the Netherlands. The paper is focused on the design and calculation of its mechanical system. The system is divided into propulsion system, steering system, and bilge pump system. The research is conducted based on literature study, discussion with experts, and surveys to the solar-powered electric boat had been designed previously for the race. Collected data are then used as input for the calculation and simulation of the vessel being designed. It is expected that the study could optimize the mechanical system of the solar-powered electric boat, and can be developed for recreational use in Indonesian waters.

Integrated ship recycling industrial estate design concept for Indonesia

引用

IOP Conference Series: Earth and Environmental Science 2022年第1期972卷

作者： Sunaryo Bagus A Tjitrosoemarto Naval Architecture and Marine Engineering Study Program Universitas Indonesia Kampus UI Depok 16424 Indonesia.

Since the implementation of the cabotage principle, the number of Indonesian flagged ships has been increasing significantly, due to the government's incentive on importation tax for used ships. The fleet is dominated by old ships, which most of them will soon be sent for recycling. The ship recycling industry has a great opportunity for the economy of Indonesia, because of its contribution to the steel industry and job creation, but on the other hand it is also a very environmentally unfriendly industry. Currently there is no ship recycling yard complies with the requirements of international and national regulations, most of them are still implementing conventional method, and are not connected to the supporting industries. Based on these issues the study was aimed to design a concept of an integrated green and sustainable ship recycling industry estate, which has all necessary industries and facilities in it, and efficiently connected with each other. Block Plan program was used to optimize the arrangement. It is proposed that five ship recycling yards, large; medium; and smaller capacity, steel mill, waste treatment facility, electricity power plant, fresh water facility, training centre, workers accommodation, hospital, and bus terminal should be included in the estate.
