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

This study investigates the influence of flow velocity on hydrodynamic flow characteristics around free-span subsea pipelines using computational fluid dynamics (CFD). Simulations were conducted at flow velocities of 1.1 m/s, 2.5 m/s, and 3.0 m/s to examine changes in mean flow field, bed shear stress, pressure distribution, and wake development. Results show that increasing velocity transitions the wake from stable laminar to turbulent with fully developed vortex streets, intensifying vortex shedding, wake asymmetry, and unsteady forces. Higher velocities significantly amplify peak bed shear stress, adverse pressure gradients, and the depth of velocity deficits, leading to prolonged wake recovery and increased turbulence. These effects have critical implications for vortex-induced vibration (VIV), hydrodynamic loading, and scour potential, emphasizing the need to consider velocity variation in the design and integrity assessment of subsea pipelines.

Abstract

This study aims to identify potential hazards and establish priority risk control strategies in nickel mining operations using the Hazard Identification, Risk Assessment, and Determining Control (HIRADC) method combined with the Fuzzy Technique for Order Preference by Similarity to Ideal Solution (Fuzzy TOPSIS) approach. The HIRADC analysis revealed several activities with high risk levels, including girder lifting, material/piping unloading, maintenance lifting, stone crushing, civil works, cathodic installation, and material loading/unloading operations. The most significant hazards identified were falling or being struck by objects, falls from heights, electrical shock, collisions with heavy equipment, and entrapment by materials. Five hazards were classified as very high risk, including falling objects (score 25), while falls from heights, electrical shock, collisions, and entrapment each scored 20. To determine mitigation priorities, the Fuzzy TOPSIS method was applied, resulting in recommended risk control strategies. The top-ranked strategies include ensuring areas are clear of falling objects and verifying lifting equipment capacity (C1), providing lifelines and full-body harnesses (C2), installing standard-compliant electrical panels with grounding (C3), segregating pedestrian pathways from heavy equipment routes (C4), and installing emergency stops and machine guards (C5). The findings demonstrate that integrating HIRADC with Fuzzy TOPSIS offers a systematic approach for effective risk management in nickel mining operations.

Abstract

The wood processing industry is a significant source of airborne dust emissions and wastewater, both of which can pose serious environmental and health hazards if not properly managed. This study aims to evaluate the performance of a mobile dust collection system utilizing wet scrubber technology at two primary operational points—cutting and sanding—while also assessing the effectiveness of treating dust-laden wastewater using electrocoagulation. The system was designed with a 55-liter tank and equipped with eight electrode plates (four aluminum and four iron) measuring 20 × 25 cm, providing a total effective area of 0.8 m². Experimental results demonstrated that the initial Total Suspended Solids (TSS) concentration of 440 mg/L was reduced to 250.55 mg/L after electrocoagulation, and further to 189.45 mg/L after filtration. Additionally, the addition of 200 mg/L of Poly Aluminium Chloride (PAC) reduced TSS from 320 mg/L to 40 mg/L, achieving an 87.5% removal efficiency. Field tests showed that the system successfully reduced airborne particle concentrations by 69.6% in the cutting area and 26.24% in the sanding area. These findings indicate that the proposed mobile wet scrubber system is effective in reducing both airborne dust and TSS levels in wastewater, making it a viable solution for dust control in wood processing industries.

Abstract

Traditional boats haves played a significant role in maritime activities such as fishing, transportation, and trade, particularly in Kepulauan Riau. These boats are typically constructed from wood, with hull designs passed down through generations. However, this traditional approach raises potential safety concerns due to the absence of standardized construction practices and compliance with maritime safety regulations. Reports of frequent accidents suggest that human factors and inadequate hull responses to wave conditions are contributing causes. This study aims to analyze the response of traditional boats from Riau Islands using numerical simulation methods. The analysis is conducted using Maxsurf software, particularly Maxsurf Motions and Maxsurf Stability, applying the linear wave theory approach to evaluate pitch, roll, and heave responses under variations in loading, speed, and wave direction. The results indicate that the boat’s intact stability and seakeeping performance meet IMO safety criteria (C1–C6) under both stationary and 6-knot speed conditions. The seakeeping evaluation conducted using Olson’s criteria under wave height variations ranging from 0.5 to 1.0 meters demonstrates that the vessel’s response consistently remains below the maximum permissible threshold. This research provides initial data and insights to better understand the intact stability and seakeeping characteristics of traditional boats in Riau Islands, particularly regarding their wave response behavior.

Abstract

This study seeks to enhance material use efficiency in plate nesting procedures for tugboat production through the application of the Taguchi method. Three critical criteria were assessed: plate profile dimensions, cutting margin, and number of parts, aimed at reducing material waste in steel plate cutting processes. Numerical simulations were performed with ProNest software, and the nesting output data were examined using Minitab to ascertain the ideal design via the Smaller-the-Better methodology. Experimental findings indicate that the ideal parameter configuration was attained with a plate profile dimension of 508 mm, a cutting margin of 10 mm, and a production quantity of 95 units. This setup resulted in little material waste, demonstrated by a maximum Signal-to-Noise Ratio (SNR) value of -49.17 dB, which is nearly zero. These findings indicate that this parameter combination can serve as a benchmark in production processes to improve material efficiency and minimize waste in tugboat fabrication.
