  • Review of the design, specifications, drawings and specified standards to ensure compliance with the applicable regulatory requirements.
  • Formal equipment audits at the premises of your engineering, constructor, manufacturer or sub-supplier – before and during manufacture.

On-site QA/QC

  • Quality Assurance of the organizations involved in the construction, manufacture and operation of your facility.
  • Review of specifications, procedures and specified standards utilized on the construction site.
  • Monitoring materials testing.
  • Inspection, witnessing or verification to establish the quality of a material, structure or system during manufacturing.

Risk Based Inspection (RBI)

Risk Based Inspection (RBI)

(Oil and Chemical Plants)

With OCA Risk Based Inspection services unplanned shutdowns of oil or chemical plants can be minimized or avoided.

RBI is used to identify and understand risk drivers to prioritize inspection-related activities, usually by means of nondestructive examination (NDE) to reduce the uncertainties around the true damage state of the equipment and the dynamics leading to such. The resulting inspection plan outlines the type and scheduling of inspection for an asset. In addition to NDE, additional risk mitigation activities identified by a RBI assessment might include a change in material of construction, installation of corrosion resistant liners, operating condition changes, injection of corrosion inhibition chemicals, etc.

We work with clients to implement Risk-Based Inspections (RBI), minimizing downtimes and ensuring equipment longevity for oil and chemical plants. Analysis of fixed equipment, piping, pipelines, and pressure relief devices at your facility using an RBI approach can increase the effectiveness of your mechanical integrity inspection program while minimizing risk to Health, Safety and the Environment (HS&E) and maximizing resource utilization.

International engineering standards and practices that relate to risk-based inspection include API RP 580 and 581, ASME PCC-3, and RIMAP. API RP 580 is an example of the minimum guidelines for implementation of an effective, credible RBI program. API RP 581 is an example of an RBI methodology's technical basis.

Key Benfits
  • A more cost-effective alternative to traditional inspection, usually by means of nondestructive testing.
  • More reliable equipment and plant operation.
  • Identification of the operational risks associated with equipment via material degradation.
  • Adherence to codes of compliance resulting in increased safety.
  • Reduction in plant downtime.
  • Items with a high probability of failure and subsequent impact are given a higher priority for inspection than items that are of low impact, allowing for a more rational application of inspection resources.
