Abstract

Metal welding of large structures often requires alternating welding on both sides, which can be costly and time-consuming. However, welding results are only sometimes perfect, and gaps often require solutions to maximize welding results. One solution is using media backing ceramic as a support that can give better results. This study aims to evaluate the effect of backing ceramic and non-backing ceramics on the strength of the tensile test results on ASTM A36 steel using SMAW welding. The results of the tensile test show that there is an effect of strength on ASTM A36 steel. Mark Ultimate Tensile Strength, the highest, was obtained on specimens that did not use backing ceramics, equal to 451.893 Mpa. In contrast, the lowest value of Ultimate Tensile Strength was obtained on the specimen using backing ceramics, equal to 428.736 MPa.

Abstract

Welding is a process that produces gas and particulate emissions that can affect air quality and public health. This study aimed to analyze the impact of welding on air quality and public health in Indonesia, using data from various sources and statistical methods. The results showed that welding increased the concentration of air pollutants such as PM2.5, PM10, NO2, SO2, O3, and CO in several big cities in Indonesia, especially Jakarta, Surabaya, Bandung and Medan. Welding also harms public health by increasing the risk of respiratory, cardiovascular disease, lung cancer and neurological disorders. This study recommends several steps to reduce the impact of welding on air quality and public health in Indonesia, such as using welding technology that is more environmentally friendly, implementing strict emission standards, monitoring and controlling air quality, and increasing public awareness and education about the dangers of welding.

Abstract

The effect of vibration dampening on lifting pipes in deep sea mining has attracted more and more attention in the last three decades; however, there are very few reports in the literature on the influence of ocean currents on pipe vibrations. Considering the geometric features of the prototype, this paper establishes the physical, mathematical, and simulation models of the lifting subsystem. A comprehensive finite element model for a deep sea mining system by OrcaFlex was developed to explore the influence of prop mass and sailing speed on deflection angles and axial loads and stresses of lifting pipes. Analytical and numerical simulations have been formulated to describe the variation rules of longitudinal vibration and axial stress at pump and buffer positions for the lifting subsystem to determine dynamic vibration damping parameters. This paper uses MATLAB and Orcaflex software to verify the mathematical model. The simulation results show that the installed DVA can effectively reduce the axial stress and longitudinal displacement at specific positions of the lifting pipe.

Abstract

Subsea pipes are a tool for flowing water, oil and gas fluids. By using this underwater pipe installation, fluids can be transferred from one place to another, from a production unit to another production unit, from a storage unit to a processing unit, and from a process transferred to a storage unit. During the production process, safety must be guaranteed to avoid fatal damage such as anchor drag, sinking ships, nets or trawls and other factors such as pipe corrosion. To prevent corrosion in pipes, we need appropriate and practical solutions. We can prevent this from happening by conducting a literature study regarding the application of optimization planning for cathodic protection in pipes. The design and analysis process discusses cathodic protection analysis, which refers to the DNV GL-RP-F103 standard criteria. Additional discussion is carried out as an optimization step, namely analyzing the type of paint used based on DNVGL-RP-B401.

Abstract

Marine logistics security is a crucial aspect of maintaining a smooth global maritime supply chain. This article explores the role of unmanned vehicles (UVs) such as unmanned aerial vehicles (UAVs) and unmanned underwater vehicles (UUVs) in enhancing ocean logistics security. UVs offer a cost-effective and flexible solution to monitor large ocean areas with advanced reconnaissance, monitoring, and tracking capabilities. This article analyses current UV technologies, advantages and limitations, and challenges in integrating UVs into marine logistics security operations. It also discusses the legal, ethical, and policy implications of using UV in the maritime context. Given the huge potential of UV in improving security and efficiency, this article highlights the importance of collaboration between industry and government stakeholders to optimize the utilization of this technology.
