Ensuring Accurate Minimum Thickness Data: How One Client Forecast a 225 Percent Return on Investment

  • An oil and gas refinery located in Corpus Christi, Texas, needed a solution to optimize inspection intervals by possessing accurate minimum thickness requirement data.
  • PinnacleART implemented mechanical integrity (MI) design calculations (as part of a current PinnacleART Risk-Based Inspection program implementation) that enabled the facility to prioritize inspections based on minimum thickness data.
  • As a result of PinnacleART’s MI solution, the facility has optimized its inspection schedule, prolonged its equipment life and reduced the risk of unexpected failures to forecast an overall return on investment of 225 percent.

An oil and gas refinery located in Corpus Christi, Texas, supplies petroleum products such as gasoline, diesel fuel and jet fuel. This refinery discovered that the minimum thickness data for many of the facility’s assets was outdated and incorrect. The facility, therefore, identified the need to acquire and utilize accurate minimum thickness data to enhance its current Risk-Based Inspection (RBI) program.


As facilities within the refining industry continue to improve their MI programs, they strive to find solutions that will help optimize inspection intervals and maintenance costs. An integral component of building an effective inspection program is understanding the required minimum thickness of each asset. The use of required minimum thickness, in combination with accurate corrosion rates, provides dependable time frames for equipment inspection and replacement.
