Performing inspection and testing in the traditional way results in operational downtime and little flexibility to utilize opportunities in operations to perform testing and inspection.

The ESIM survey arrangement includes 

  • The use of alternative test methods (fault simulations, isolation and local testing, built-in test functionalities, etc.)
  • Inspection and testing partly performed by the owner's qualified personnel
  • Inspection and testing performed on a continuous basis
