Simulations For Structural Integrity Assessment

TWI identifies and applies the most appropriate technology to support our client’sdecisions regarding the safe operation of a structure. Our activities span across the aerospace, automotive, oil and gas, and power generation sectors, and include the structural integrity assessments for:

  • FEA for an FFS on crack-like flaws on a power boiler reheater header
  • Creep analysis using FEA for an FFS on the main steam pipeline found susceptible to creep damage
  • Creep-relaxed stress analysis using FEA for an FFS on high-energy piping of a power boiler
  • Fracture and fatigue of petroleum road fuel tankers with the results presented to UK Parliament
  • Corrosion of well conductors, incorporating in-line inspection (ILI) data directly in the models
  • Dents and gouges of subsea pipelines that were identified by remotely operated vehicles
  • Tubular joints in offshore jacket structures, using constraint-based fracture mechanics
  • Fracture and strength of radioactive waste disposal canisters
  • Hydrogen-induced stress cracking (HISC) of duplex stainless steel joints forsubsea service
