Understanding each asset’s minimum thickness requirements is an integral component to building an effective inspection program. The use of required minimum thickness data, in combination with accurate corrosion rates, provides facilities with dependable time frames regarding equipment inspection and replacement. Because outdated and incorrect minimum thickness data results in unnecessary inspections, facilities should strive to maintain accurate data.
Read our case study, “Ensuring Accurate Minimum Thickness Data through Mechanical Integrity Design Calculations” to learn about how minimum thickness data can enhance an RBI program.
If equipment documentation is lacking, or the current minimum thicknesses are thought to be too conservative, PinnacleART can perform design calculations for the vessel by using data-like vessel metallurgy, design/configuration, dimensions, and internal processes to output the minimum required thicknesses for the major vessel components. If this data is lacking, PinnacleART can send its field teams to strap the vessel and perform a Positive Material Identification (PMI) to feed into the calculation model.
By utilizing accurate minimum thickness data, clients are able to effectively manage risk, while decreasing unnecessary inspections and optimizing costs.
Fitness for Service (FFS)
Fitness for Service (FFS) analyses are performed on mature equipment that may have degraded in service, in order to identify whether it is safe to operate the equipment. If a vessel has seen damage (general corrosion, localized corrosion, cracking, out of roundness, etc.) as specified in API 579, PinnacleART can perform Level 1, Level 2, or Level 3 FFS analyses as needed to determine the vessel’s fitness for service and provide recommendations for repair or replacement.
FFS analyses can help facilities optimize their costs by understanding whether equipment can be safely operated until a more permanent solution can be implemented. On the other hand, FFS can also help facilities manage risk and safety, by understanding when an immediate repair or replacement is needed.
