Abstract

Industrial revolution 4.0 era represents a paradigm shift in manufacturing and technology, which is characterized by an integrated and interconnected system to support the operation of an industry. Many countries contributed to this era, including Indonesia. As a maritime country, maritime-related products have the potential to be offered. Remotely operated vehicles (ROV) is a form of digitalization product that is frequently used to support the operation of the maritime industry. Therefore, ROV is manufactured locally to provide easier access to industries demanding ROV. Digital manufacturing for ROV can bring further contributions towards industrial revolution 4.0, which involves the usage of digital technologies such as computer-aided design and manufacturing (CAD/CAM), internet of things (IoT), artificial intelligence (AI), and robotics to create an integrated manufacturing system. Furthermore, digital manufacturing information system provides real-time information during the manufacturing process. According to this study, digital manufacturing can significantly improve the efficiency and integration in manufacturing the ROV.

Abstract

The paper explores the innovative application of lineless technology in automatic mooring systems through the utilization of vacuum systems. Departing from traditional mooring methods, this approach offers enhanced safety, efficiency, and environmental sustainability. The study provides a concise overview of vacuum-based lineless technology's integration in automatic mooring, emphasizing its unique advantages and potential challenges. Vacuum-based lineless mooring systems employ advanced suction mechanisms, sensors, and control algorithms to achieve secure vessel mooring without manual intervention. This novel approach significantly reduces operational risks, minimizes wear and tear, and optimizes berthing precision. The paper delves into the technical intricacies of sensor integration, real-time monitoring, and adaptive controls, ensuring reliable and safe mooring even under dynamic environmental conditions. The adoption of vacuum-based lineless technology introduces considerations like technological reliability, cyber-physical security, vessel adaptability, and port infrastructure compatibility. Through a blend of literature review and practical insights, the paper evaluates the feasibility and economic implications of this approach, highlighting its potential to revolutionize maritime practices. As the maritime industry seeks forward-looking solutions, vacuum-based lineless mooring technology emerges as a promising avenue for reshaping vessel berthing and contributing to sustainable port evolution.

Abstract

Inaportnet is a digital system used to facilitate operational systems at Indonesian ports whose system is similar to the portbase in the Netherlands which also has the same function and purpose. The main aim of this research is to compare the level of effectiveness and efficiency of the Inaportnet work sys-tem which is considered to be still far from the Portbase work system which has been proven operationally quite effective in Dutch ports based on primary data collected from interviews with the Dutch Portbase and also Inaportnet Indonesia. In the interview results, significant differences were found in the way these two systems work where Portbase prioritizes security by carrying out two-step verification to prevent data leaks and also the possibility of sys-tem hacking. On the other hand, Inaportnet has not done this so it has the po-tential to experience disruption when the system is not available and creates uncertainty in recording cargo volumes where the recording process is still done manually by relying on documents from shipping agents so that if Inaportnet is not available, it makes it difficult to access documents digitally and need a long time. The results of this research show that if the Inaportnet system is modified and slightly combined with the Portbase system on certain systems, the operational system will likely increase its efficiency and the data in the Inaportnet system will be more reliable and trustworthy so as to in-crease cooperation and strengthen trust between incumbent.

Abstract

A floating dock (FD) is a platform for ship construction and repair. Structural damages to a FD can significantly reduce ship docking productivity, leading to substantial losses for shipyard companies. In order to restore its operational capabilities, repairing the damaged FD becomes essential. This research aims to plan and analyze the schedule to ensure the efficiency and effectiveness of FD repair activities. The process begins with the establishment of a Work Breakdown Structure (WBS), followed by determining the required man hours (MH) and scheduling using the Precedence Diagram Method (PDM). Finally, the S-curve is made for monitoring the progress of the FD repairment. The findings of this study, based on a case study involving a 6700 TLC FD, reveal a WBS comprising 66 repair tasks including two tasks for FD testing and finishing in addition to four areas of hull, walls, deck and tanks, piping systems, and machinery. The MH requirement for these tasks is 4048 MH. From the scheduling results, it was found that the duration was 12 days, with a total of 53 critical activities and 25 critical paths in the floating dock repair work using the precedence diagram method.
