This remaining life assessment assessed the thickness and corrosion rate characteristics of A516 Grade 70 carbon steel, a material widely used in the fabrication of pressure vessels and boilers, including spherical tanks. The material was evaluated through ultrasonic non-destructive testing, with the aim of determining the minimum thickness and corrosion rate, based on field data collected by the inspector. The data was then analyzed to determine the minimum allowable thickness and estimate the remaining life of the pressure vessel based on API 510 standard. The study results showed that all components examined were within safe limits for use, above the required thickness (actual thickness > required thickness). The calculation of the highest corrosion rate is on the Top Head Plate 7 component, which is 0.067 mm/year, so this component has the shortest remaining life, which is 54.06 years. This study also calculates the maximum allowable working pressure (MAWP) value which is a reference to ensure the safety of pressure vessels when operated. The working pressure when operated must not exceed the calculated MAWP value. The calculated MAWP value is in the range of 6.99 to 8.12 psi.

Security of IT infrastructure is critical in the modern digital environment, particularly for industries that manufacture clothing. The application of the Wazuh Security Information and Event Management (SIEM) system to improve security monitoring and compliance for an IT system in the apparel industry is the main topic of this study. To improve the apparel industry cyber threat monitoring system in real-time monitoring, detecting the threat vectors that support the centralized management system, to meet these objectives of the company, an SIEM security management system has been installed and configured with the components of Wazuh manager, indexer, Wazuh agent, and Wazuh dashboard as well. An Oracle virtual lab environment was created to install and configure the Wazuh system a robust Linux operating system was installed at the server level and Windows 10 was installed on the client end to the authenticity failure of the security system. To implement the Wazuh system, the project management guideline was followed which ensured the planning and implementation of the project, testing phases, and along with review and maintenance. Wazuh security management system successfully identified the authentical failure reports and vulnerabilities and generated automated reports from the system that showed the result of 1 critical, 19 high, and 5 medium levels of vulnerabilities shown in Figure 6, and the necessary patch recommended to solve the critical issues. On the other hand, the system also generated security events as well as integrity monitoring system reports. The deployment of the Wazuh security management system ensured the robust cost-effective security management system with high quality for detecting cyber threats which supports the regulatory and compliance requirements and is a viable tool for the apparel industry to protect the stakeholders’ interest.
