Subsea Pipe Joints and Tee Assemblies
  2. 2. ©2013 QuEST Global Services Pte Ltd. Confidential 2 Subsea Pipe Joints and Tee Assemblies The analysis was based on the following load scenarios: Onshore FAT (Factory Acceptance tests) Tie-in of Branch System Pressure Test Operational load case Installation load cases Approach Verify the design of under sea pipe joints under the operating conditions as per different applicable codes and prove the structural capacity of the under sea pipe joint assembly. Scope Established 3D model (geometry and mesh) of joint body based on Drawings.  Established all load cases and combinations.  Set-up analysis sequence and run analysis.  Performed code checks.  Geometric changes developed as and when required.  Documentation of work and Technical report Results Improvements in design and documentation Improved analysis results Cost savings of about 32% in terms of labor cost Benefits Domain Oil & Gas Sub Domain Subsea Software FEA (Ansys,) Codes & Standards Multiple Discipline Mechanical Cad model of branch assembly Stress Plot Mesh density kept across Tee neck FEA Results Stress Plot
