"Ansys Parametric Design Language’s superior customization capabilities in combination with Workbench Scripting Capabilities provide for visualization of damage. This provides critical engineering insights and enables product design of subsea oil and gas equipment to be qualified against ASME BPVC VIII, Division 3."
— Abhineet Gupta, Engineer II | PSG-FEA / FMC Technologies India Pvt. Ltd.
Design of subsea oil and gas equipment has moved to high pressure and high temperature domains. With pressures beyond 15,000 psi and temperatures beyond 350 F, designs have to be qualified per ASME BPVC VIII, Division 3, which requires the cumulative damage on the equipment to be below 1. Local damage check evaluates the equipment’s design against local strain rupture.
Due to increasing depth of oil extraction, the structural loading requirements for subsea components are increasing, but there are also space and weight constraints on these components. To reduce over-engineering and promote value engineering, engineers must visualize damage distribution in each component. Because Ansys Structural does not have a method to plot damage, the challenge was to develop a customized method using Ansys’s scripting capabilities.
