Abstract
Undesirable vibrations triggered by ocean currents generated in undersea crude oil pipeline systems shorten their lifespan and potentially cause them to fail. A crack is a type of damage that can occur during the pipeline transportation in the petroleum industry. Extreme weather conditions could also cause significant equipment damage. Using the energy equations, this study examines the natural frequency, link between pressure change, velocity change, and temperature change of crude oil flowing through the pipeline. Computational fluid dynamics (CFD) using ANSYS® fluent is used to create a typical presence of cracks in the pipeline, which is then used to train the equations to generate a model of fluid behavior. This study shows that using frequency as a sign the system under ideal circumstances successfully identifies a fault situation as non-conforming and suggestive of a statistically significant shift in the pipeline flow. The findings revealed a clear correlation between the size of the crack and the loss of pressure; the larger the crack, the greater the pressure loss. As the crack depth increases, the frequency varies according to the pipe’s support, flow velocity, and internal temperature of the fluid. This research indicates that the use of frequency sign for pipeline operation could provide significant improvements to the business in terms of cost, safety, and environmental protection.
