IRIS Tube Inspection with Immediate Response

Gas cooler tube before clean Gas cooler tube inspected by Tube Tech Morning cleaning information

Tube Tech responded immediately to an offshore platform to perform an IRIS tube inspection

Tube Tech had recently worked for this client’s onshore refinery when they were contacted by personnel on a 22 year old North Sea platform who required an immediate inspection of tube bores on their gas coolers. The inspection was to determine if any damage had been caused by the coolers running with a high pressure drop across the unit which tripped the whole platform limiting production to 50%.

Challenge:

  • Urgent mobilisation was essential.
  • The two horizontal gas coolers contained 1491 Duplex tubes of dimensions 0.75” O.D. x 18 BWG nominal wall thickness.
  • The objective of the inspection was to detect and measure any wall losses present in any of the tubes tested.

Solution:

  • Tube Tech mobilised their inspection team and equipment immediately to arrive on the platform within 36 hours of the proposal acceptance
  • An Internal Rotary Inspection System (IRIS) and the principles of Pulse Echo Ultrasonics were used for the inspection
  • Sufficient tubes were inspected to allow the client to make an informed judgement regarding productivity of the coolers
  • None of the inspected tubes displayed reportable wall loss (10% or greater)

Tube Tech Comment

Scott Donson, Sales Manager: “Once again Tube Tech demonstrated our ability to respond quickly and efficiently to the needs of the offshore industry. Our client was pleased not only with our rapid response but also the fact that there was no wall loss on their tube bores.”

Client Comment
