Abstract

Many factors affect the hit probability in a shooting between surface combatants, which involve the environment where the warfare takes place, the weapons and ammunition used, the shooting personnel and so on. Due to technological developments, these influencing factors can be improved for the better results. These influencing factors are interrelated with each other, and can even reduce each other. Bayesian Network is a method applied for probability analysis that considers the relationship of these influencing factors and is arranged in a Directed Acyclic Graph (DAG). Bayesian network structure is composed of initial information (prior probability) and the relationship between conditional probabilities at each node that have been determined based on expert knowledge or certain analysis. Such conditional probability is only valid for data analysis at the time of collection. In this study, a Bayesian network model for naval warfare, surface ships are involved was developed. The model is based on the results of a literature study and validation based on experienced professionals. The relationship between nodes shows five main influencing factors are fire control system, ammunition, personnel, movement of the target being shot and environmental factors dominated by the marine environment.

Abstract

Integrating Lithium Battery Energy Storage Systems (LBESS) into offshore Commissioning Service Operation Vessels (CSOV) poses significant safety concerns, including fire, explosion, and toxic gas release. The expanding offshore wind industry increases demand for CSOVs equipped with energy storage, making robust risk management essential. This study addresses the critical need to understand and manage LBESS hazards on CSOVs, given the absence of comprehensive international regulations and inherent lithium battery risks like thermal runaway. This study utilizes Risk Assessment data and the Analytic Network Process (ANP) to analyze these hazards and identify optimal mitigation strategies. The research systematically identified six distinct hazards, eighteen main causes, and twenty specific sub-causes through hazard identification (HAZID). A purposive sampling method selected seven qualified practitioners with at least three years of experience in BESS security and risk assessment on CSOVs, including ship construction supervision. Data was collected via a questionnaire using pairwise comparisons and the Saaty scale, processed with Super Decisions software, and combined using Geomean calculations. The ANP analysis shows safety is the top priority for LBESS implementation (63.6%), significantly exceeding environmental (16.3%) and operational (10.2%) factors. Within safety, explosion (39.0%) and fire (25.9%) are the most prevalent hazards, with thermal runaway and battery electrolyte decomposition being key contributors to LBESS failure. For mitigation, the analysis highlights Battery Physical Design and Protection (31.5%), Battery Monitoring and Control Systems (27.9%), and Operational Procedures and Training (15.4%) as crucial. Prioritizing safety is essential for LBESS deployment on CSOVs, with explosion and fire being the most severe threats, and robust engineering and operational protocols are critical mitigation strategies.

Abstract

Safety is an important aspect of the industrial process. Failure of system and mechanism endanger both human and environmental safety. Safety is obligated to be implemented precisely and thoroughly to prevent failure consequences. One of the preventive implementations is to map out safety devices in the form of SIS (Safety Instrumented System) and other layers of protection. However, to acknowledge this safety device performance used SIL (Safety Integrity Level). This final research is intended to analyze Fuel Gas systems on Onshore Receiving Facilities (ORF). HAZOP (Hazard Operability Study) as process hazard analysis with deviation during the operation so that the risk level is known. SIL verification towards SIL target is SIL-2 refer to IEC 61511 standards by FTA (Fault Tree Analysis) method. From the HAZOP study can be concluded that over-pressure becomes a top hazard to all nodes due to the most severe consequences, the highest likelihood (medium risk). The calculation result of PFDavg is Node 1 (Fuel Gas Scrubber V-6060) is 6,22E-03, Node 2 (Fuel Gas Filter Separator S-6060A) is 1,24E-03, Node 3 (Fuel Gas Filter Separator S-6060B) is 1,24E-03, Node 4 (Fuel Gas Superheater E-6060) is 1,21E-03, and Node 5 (Instrument Gas Receiver V-6070) is 2,23E-03. The conclusion of this research shows that five components of the Fuel Gas System fulfill the SIL-2 target, therefore, doing a re-design to add a safety device is unnecessary.

Abstract

Indonesia is known as the biggest archipelagic nation on the planet and is between two significant seas. In a roundabout way, Indonesia has tremendous regional water when contrasted and the land territory itself. With this, obviously, it tends to be said that Indonesia has colossal potential in the oceanic area, particularly since the Indonesian sea domain has consistently been a worldwide transportation path. This potential should be used ideally by this country, considering the mechanical advancement in Indonesia itself can be supposed to be very quick. Innovation that is utilized carefully and applied to the sea world can give Indonesia benefits for a few areas, for example, the economy, industry, and even schooling. Innovation that can be used in the oceanic world, particularly in the field of transportation is PC illustrations innovation, which in its application can be utilized during the time spent to plan, fix and support, reproductions and preparing for training and others with the 3D display. Virtual Reality (VR) is a counterfeit world or can be said as a computerized world where everything in there is the consequence of representation made utilizing 3D innovation from the PC. Virtual Reality permits us to cooperate and encounter encounters that are practically like this present reality. The reason for this exploration or the last task is to use innovation that is growing quickly well in the learning cycle in the oceanic world. With Virtual Reality, it is conceivable to make new learning strategies for training, particularly in the presentation of segments of the fuel oil framework on the ship. Because of a few restrictions confronted when mentioning direct objective facts to the ship, including authorization or admittance to enter the ship, time is restricted. Along these lines, it is normal that utilizing Virtual Reality can help the learning cycle for training by making an application that can be utilized in perceiving and understanding the segments of the fuel oil framework on a ship.

Abstract

Maintenance is one of the important things to maintain a company in the industry. A company, such as LNG production company, must be able to produce and meet energy needs independently to support all operations, such as cooling water system that functions to control the temperature and pressure so that the production process runs optimally. If this system is disrupted, there will be excess use of water, waste water, and energy costs needed which result in higher total operational costs. With good and right care, it can reduce all risks posed. One component that plays a role in the cooling water system is a pump. This pump serves to flow the cooling water which is seawater to the LNG industry plant. At present, the amount of Work Order data recorded from the problems obtained from the pump requires maintenance updates. In this study, the method in the maintenance programs are used based on the Reliability-Centered Maintenance (RCM) implementation. RCM will increase cost efficiency, reliability, pump uptime, and propose maintenance tasks. Beside pump, the reviewing also involve supports components that affect pump optimization. In this paper, the functions, causes, and effects are identified and the new scheduled maintenance tasks are shown.
