The IIS Group is the acknowledged leader in service and support for inspection planning and RBI studies according to the recommended practices API 580 and API 581 in Italy and abroad. Our API-RBI Users Group membership dates back to 2001. The IIS Group is licensee for the API RBI™ software.

The End Users apply the API-RBI Technology for the plant operational risk management system, focusing inspection efforts and resources to those fixed equipment at the highest failure risk. API-RBI Technology provides the basis for making informed decisions on inspection frequency, the extent of inspection, and the most suitable type of NDE to identify expected damage causes by potential evaluated damage mechanisms.

It is a fact that a relatively large percentage of risk in an operating plant is associated with a small percentage of the equipment items. The API-RBI Technology allows the shift of inspection and maintenance resources to provide a higher level of coverage on the high-risk items and an appropriate effort on lower risk, but larger in quantity, equipment.

Expertise we have reached establishes our leadership in Italy as provider of this type of service.
