Extended Subsequent Applications Review ("ESAR")

Extended Subsequent Applications Review (ESAR) in Oil & Gas: Navigating Program Transitions and Changes

In the complex and dynamic world of oil and gas, projects often evolve, requiring adjustments to their execution and operational environment. This can involve shifts in contractor conditions, transitions between development phases, or substantial modifications to existing systems. To ensure ongoing compliance and safety, the oil and gas industry utilizes the Extended Subsequent Applications Review (ESAR) process.

What is an ESAR?

An ESAR is a formal review conducted in lieu of a full C/SCSC (Critical Safety & Security Control System) demonstration review. It's triggered by significant changes that impact the program's safety and security, such as:

Program Phase Transitions: Moving from research and development into production, or from one stage of development to another.
Contractor Facility Changes: Relocating a program to a new facility, involving different infrastructure and procedures.
Significant C/SCSC System Modifications: Major changes to the design, implementation, or documentation of safety and security systems.

Benefits of an ESAR:

Efficiency: ESARs offer a more streamlined approach compared to full C/SCSC demonstrations, saving time and resources.
Targeted Evaluation: By focusing on the specific changes, ESARs ensure that the review process remains efficient and effective.
Continuous Improvement: ESARs provide an opportunity to identify potential weaknesses and implement corrective actions, enhancing safety and security protocols.
Compliance Verification: They help verify that the program continues to meet regulatory requirements, even after significant changes.

The ESAR Process:

The ESAR process typically involves the following steps:

Triggering Event: Identifying the specific change that necessitates an ESAR.
Documentation Review: Thoroughly examining documentation related to the changes, including design documents, operating procedures, and safety analyses.
Assessment: Evaluating the impact of the changes on the C/SCSC system and determining if they introduce any new risks.
Corrective Action Plan: Developing a plan to address any identified risks or non-compliance issues.
Implementation and Verification: Implementing the corrective actions and verifying their effectiveness.
Documentation: Updating relevant documentation to reflect the changes and the results of the ESAR.

Conclusion:

The ESAR process is a critical tool for ensuring ongoing safety and compliance in the oil and gas industry. It provides a structured approach for managing program changes, minimizing risks, and maintaining a robust safety and security framework. By effectively utilizing ESARs, stakeholders can navigate evolving project landscapes while maintaining a high level of safety and operational integrity.

ESAR Exercise:

Scenario:

An oil and gas company has completed the research and development phase of a new exploration project and is now transitioning to the production phase. This transition involves moving the project to a new facility with a different operating environment and utilizing a new contractor.

Task:

Identify the key changes that necessitate an ESAR in this scenario.
List the essential documentation that needs to be reviewed as part of the ESAR process.
Develop a potential corrective action plan if any risks or non-compliance issues are identified during the ESAR assessment.

Exercise Correction

1. Key Changes:

Facility Transition: Moving to a new facility with potentially different infrastructure, procedures, and safety protocols.
Contractor Change: Involving a new contractor with their own working practices and safety standards.
Phase Transition: Moving from research and development to production, which often involves changes in operational processes and safety requirements.

2. Essential Documentation:

New Facility's Safety Procedures and Risk Assessments: These documents should be reviewed to understand the specific safety protocols in place for the new facility.
New Contractor's Safety Management System: Understanding the new contractor's safety procedures, training programs, and safety performance data.
Project's Original Safety Analysis and Design Documents: To compare with the new facility's requirements and ensure continuity of safety practices.
Updated Safety Analysis and Risk Assessments: Conducting a new assessment considering the new facility and contractor, ensuring they meet the project's requirements.

3. Potential Corrective Action Plan:

This would depend on the specific risks identified during the ESAR assessment. However, some general examples could include:

Additional Training: For new contractors and facility personnel to familiarize them with the project's specific safety protocols.
Modifications to Safety Systems: Adjusting safety systems or equipment based on the new facility and contractor's capabilities.
Development of New Procedures: Creating new operating procedures that address specific safety risks or differences between the old and new facilities.
Implementation of Monitoring Systems: Establishing robust monitoring systems to track safety performance and identify potential issues early on.
