Best Practices for Commissioning of Major Oil and Gas Facilities in Nigeria

Abstract Commissioning is not a project close-out activity or a mere ribbon-cutting event. It is a pivotal project activity that demands meticulous, comprehensive planning and execution under a robust monitoring and control framework. Commissioning is indispensable for the safe and reliable transition from construction to operation of oil and gas facilities. Project commissioning is riddled with critical challenges that put personnel, facilities, and the environment at risk. This phase of the project is particularly susceptible to pressure from key stakeholders, especially when earlier phases have caused delays without adequate adjustments to the project's timeline for completion. Furthermore, the expertise of commissioning engineers significantly influences progress in facilities design, construction, operation, and maintenance. Their experience ensures decision accuracy, agility, and flexibility when unforeseen events occur. Therefore, it is crucial to communicate the responsibilities and authority of commissioning personnel clearly. Key considerations for guiding leadership in decision-making and stakeholder management during commissioning encompass the unique aspects of facility location(s) - green field vs. brownfield; the complexity of the facility and the nature of fluids to be handled or processed; activity timelines; economic considerations which may necessitate phasing of works to aid flexibility and early product to market for quick wins; adoption of appropriate commissioning frameworks and strategies; and compliance with industry standards and regulatory requirements. In conclusion, understanding the processes and activities involved in commissioning oil and gas facilities helps minimize risk, manage stakeholders’ expectations, and broker support when challenges or unplanned events occur in this project delivery phase. An After-Action Review or lessons-learned session will help deliberate and document gains and challenges encountered for referencing and supporting future projects.
