DENT ANALYSIS ON GAS BOOT VESSEL WITH ANSYS SIMULATION BASED ON STADARD API 579

Dent damage is a defect that occurs in gas boots. Damage can affect the process's main application function of separating oil and gas in a gas boot. This paper presents data from determining industry data and analysing it using Ansys Simulation based on physical conditions. Following that, an assessment using standard API 579 is performed, followed by comparing these methods to determine whether this gas boot is suitable for use in this industry. This research is based on two methods. According to Ansys 19.2, software simulation is performed using an explicit dynamic simulation condition when a gas boot is not hit with an indenter and a static structural simulation when a dent occurs. The maximum equivalent stress simulation obtained was 46 MPa, and the maximum elastic strain was 0.31 mm. Using static structural simulation, the maximum Von-mises using analytical analysis was 45.85 MPa, so the error was 3.27 per cent. Based on the Interaction Diagram, the acceptability of dent damage is 0.007yσ, which is within acceptable limits.
