Fitness for Service

A failure in your process vessel does not need to be the end of its useful life. With the right kind of action, you can still use your process vessel in your operations, maybe for several years to come.

With help from the American standard API 579 Fitness for Service, we can give you an assessment of your pressurized equipment in an effective and systematic way. We use methods like screening and advanced analyses to assess failure mechanisms of different kinds.

We execute a thorough evaluation and assessment of the possibilities for your equipment to continue in operation in line with national regulations. We also assess the residual lifetime of the vessel, tank or pipe.

We evaluate failure mechanisms such as:

  • Brittle fracture
  • General metal loss
  • Local metal loss
  • Pitting corrosion
  • Damages associated with HIC and SOHIC
  • Weld misalignment and shell distortions
  • Crack-like flaws
  • Creep damage
  • Fire damage
  • Dents and gouges
  • Laminations
