Abstract

The ship's hull construction must withstand all loads, be made as light as possible and comply with regulations. The purpose of this study was to determine the maximum strength limit of double bottom ship construction with manhole form variations. Research design for this study; literature studies, field studies, and simulations using ANSYS. The results of the existing double model structure strength values for the maximum stress values in the sagging hogging state are 236.60 MPa and 154.18 MPa. Von Mises stress values are 227.94 MPa and 136.26 MPa. The shear stress values are 131.5 MPa and 77.36 MPa. The maximum deformation is 0.0049 m, and the safety factor is 1.346. The total construction weight is 201.83 metric tons. The best results of the analysis of variation were found in Model B1, which changed the hole ratio from 0.75 to 0.6 and increased the hole dimension by 200 mm. The maximum stress values of Model B1 in the sagging-hogging condition are 186.93 MPa and 141.54 MPa. Von Mises stress values are 238.72 MPa and 184.82 MPa. The shear stress values are 113.37 MPa and 137.42 MPa. The safety factor is 1.337 m, and the maximum deformation is 0.0034 m.

Abstract

As the marine industry now is running toward the green and more efficient propulsion system, the optimization has also become a primary part of the research. This research study is focusing on the optimal sizing of Hybrid Energy Storage (HESS) in electric ship using Multi-Objective Genetic Algorithm (MOGA). By integrating the battery and supercapacitor (SC), it helps cover the load demand while enhancing a good performance to the ship. This research study is to optimize sizing of HESS with a suitable Energy management System (EMS) to desired the intention of minimize the total cost of HESS and degradation of the battery. The proposed model addresses the complexity of HESS while optimized the distribution of power for both the battery and SC, handling the load condition.

Abstract

The fossil fuel emissions from the ship have significant impacts on climate change, environmental quality, and human health. The marine sector has consequently grown increasingly interested in implementing greener and more sustainable energy solutions. The electric propulsion ship is powered by hybrid energy storage has the ability to lower emissions, improve the power quality, and lower fuel consumption. There are many types of energy storage system such as battery, supercapacitor, hydrogen, etc. In this study, the combine of battery and supercapacitor are chosen as a hybrid energy storage system to supply power to the electric ship and diesel generator is an additional power source. The main objective is to sizing the hybrid energy storage system to minimize the total cost while maintaining reliable energy supply. The optimal sizing of each component is conducted in MATLAB using Genetic Algorithm. The result indicates that the optimal power rated of Pbat is 100 kW and Psc is 301.19 kW, while the optimal capacities rated of Ebat is 121.27 kWh and Esc is 109.86 kWh. Over a 20-year period, the total of this project is $1,390,422.

Abstract

Mobile crane lifting activities carry a significant accident risk, especially when performed in tandem configurations. The main risk comes from the possibility of failure of the load cell component which plays an important role in actual load measurement. This research aims to analyze the potential failure of the load cell function in tandem lifting operations using the Fuzzy Fault Tree Analysis (FFTA) method. Data were collected through literature studies, field observations, and interviews. The FFTA method is used to identify factors that cause failure and calculate the probability of failure quantitatively. The investigation identified that the primary variables leading to load cell failure include overload situations, internal component damage, and external impacts. The highest probability of failure was recorded in the material fatigue scenario due to damage to the cable. These findings highlight the need of instituting preventative maintenance programs and conducting frequent inspections of load cell components to reduce the risk of workplace accidents.

Abstract

A generator is vital for ship operations, serving as a source of electrical power generation on board. The electrical system changing loads every second. Even with these changes, the power demand stays steady and must be supplied correctly. Voltage stability shows how well the system can keep the voltage steady during normal operation or after something goes wrong. Things like added loads or changes in the system setup can also affect this stability. The method used in this research is circuit modeling that conducted using the Electrical Transient Analysis Program (ETAP) software to collect data. This modeling is essential for designing a system that can be effectively simulated. The result is the voltage and frequency stability values while the air compressor motor operates at 4.5kW showed no significant voltage changes. In contrast, when the electric bow thruster motor, operating at 335kW, runs, the voltage dropped to 85% within 6.5 seconds. During a short circuit at the 15th second compartment bus, the engine room bus experiences a voltage dropped of 77%, while the hull compartment bus dropped by 45%. This showed that the system is unsafe for the equipment, as the as a voltage.
