Cost-Effective Validation of HP/HT Subsea Equipment Using Seawater Hydrostatic Head

摘要

Validation testing of subsea equipment designed for high pressure/high temperature(HP/HT)applications is necessary but can be extremely expensive and infeasible.The complete paper presents a practical approach for validating design-verification analysis for subsea equipment,using a representative pressure valve block to correlate finite-element analysis(FEA)predictions for strain changes with actual measured changes.The design methods use the guidelines in technical report API 17TR8,and load cases per API 17TR12.
