Navigating the Deviations in Oil & Gas: When and Why to Depart from the Plan

In the demanding world of oil and gas, strict adherence to specifications and contracts is paramount. However, there are times when deviations from the established plan become necessary. This is where the concept of a deviation comes into play.

A deviation in oil and gas refers to a written authorization, granted prior to the manufacture of an item, to depart from a particular performance or design requirement of a contract, specification, or referenced document, for a specific number of units or specific period of time.

Essentially, a deviation is a controlled and documented exception to the standard. It's a crucial tool for addressing unforeseen challenges and ensuring project success, but it should be approached with caution.

Why are deviations necessary?

While adherence to specifications is crucial for safety, efficiency, and quality control, several factors can necessitate a deviation:

  • Unforeseen circumstances: Unexpected site conditions, material availability issues, or even technological advancements might require adjustments to the original plan.
  • Technical improvements: A deviation might be needed to incorporate a better, more efficient design or technology that was not initially available.
  • Cost optimization: Deviations can help streamline production or reduce expenses without compromising safety or functionality.

The Process of Obtaining a Deviation

Obtaining a deviation is not a simple matter of making a request. It involves a rigorous process that ensures the deviation is justified and properly controlled:

  1. Request Submission: The request must be clearly documented, specifying the desired change, the reason for the deviation, and its potential impact on the project.
  2. Review and Approval: The request is reviewed by relevant stakeholders, including engineers, project managers, and quality control personnel.
  3. Technical Evaluation: A thorough analysis is conducted to ensure the proposed deviation meets safety and performance standards and does not compromise the project's integrity.
  4. Documentation and Authorization: Once approved, the deviation is formally documented, including the rationale, approval signatures, and the effective period.

Navigating the Risks of Deviations

While deviations offer flexibility, they also present potential risks that need to be carefully considered:

  • Impact on Safety: Deviations should never compromise safety standards. Thorough analysis is crucial to ensure the proposed change does not introduce new risks.
  • Performance Degradation: The deviation must be carefully evaluated to avoid compromising the functionality or performance of the equipment or system.
  • Contractual Implications: Deviations can impact contractual obligations and may require modifications to the original agreement.

Conclusion

In the demanding environment of the oil and gas industry, deviations are sometimes necessary to address unforeseen circumstances, improve efficiency, or incorporate new technology. However, they should be approached with meticulous planning, careful consideration, and a commitment to maintaining safety and quality standards. By following a structured process for obtaining and managing deviations, companies can ensure these exceptions are used effectively to navigate challenges and achieve project success.

Exercise:

Scenario: You are working as a project engineer on an offshore oil platform construction project. During the installation of a critical pipeline, you discover that the original design specifications require a material that is no longer readily available. The available alternative material offers similar functionality but is slightly less resistant to corrosion.

Task: Outline the steps you would take to address this situation, including the process of obtaining a deviation.

Exercice Correction

Here's a possible solution:

  1. Document the situation: Thoroughly document the discovery, including details about the original specification, the unavailable material, the alternative material, and its properties (including corrosion resistance).
  2. Analyze the impact: Assess the potential impact of using the alternative material on the pipeline's lifespan, functionality, and safety. Consider potential mitigation strategies to address the lower corrosion resistance.
  3. Prepare a deviation request: Draft a clear and concise deviation request, outlining the situation, the alternative material, the analysis of its impact, and any proposed mitigation strategies.
  4. Submit for review and approval: Submit the deviation request to the relevant stakeholders (project manager, engineering team, quality control, safety team).
  5. Engage in discussions: Be prepared to discuss the request in detail with stakeholders, addressing concerns and answering questions.
  6. Technical evaluation: Work with the engineering team to conduct a technical evaluation of the proposed change, ensuring it meets safety and performance standards.
  7. Documentation and authorization: Once approved, document the deviation with all relevant details, including the rationale, signatures, and the effective period.
  8. Implementation and monitoring: Ensure the alternative material is correctly used, and monitor its performance over time.
