Through this paper, the author intends to share the valuable experience and benefits of introducing a Baseline Risk Based Inspection (RBI) program in a structured manner from the earliest possible project stage including those of FEED, EPC and beyond into the commissioning and Operating stages.
ADMA is known for its pioneering and innovative approach. As one of the major Oil & Gas producers worldwide, ADMA philosophy is to build a culture where critical Integrity Deliverables are embedded through customsied locally designed Codes of Practice, knon as "Integrity Assurance in Projects" that is monitored through a Value Assurance Process (VAP) stages. This enables robust control of Integrity Measures upfront and early identification of Integrity risks, with proactive mitigations based on experience from previous Projects. Following this initiative enables a structure that is directed towards the prevention of operating critical facilities and minimizes the liklihood of unknown HSE and business risks impacting the delivery of the project to the production phase.
One of the key Integrity deliverables is the implementation of Baseline RBI Passport. The Passport system has been broadly adopted across ADMA operational sites and supports the safe continuous employment of assets to meet production targets. Here, the passport concept is embedded from the embryonic stages of the project activities and is implemented by the Project Management Team (PMT) that have the highest level of knowledge regarding the project design and a complete appreciation of the as-built data and ongoing required functioning parameters of the asset process systems. This innovative approach has been successfully implemented in all of the current on-going Full Field Development projects and has proven to be of great value by ensuring a high quality result whilst attracting significant cost savings. Some of the key successes realized through the roll out of the Baseline Risk Based Inspection (BRBI) initiative include:
Early interventions through detail assessment. This was achieved by using API-580 comined with in-company developed GDL-064 guidelines for mode of failure, damage mechanisms and probability / consequences of failure. The project realized advantages such as the timely realization of risk reduction. Early identification of these risks led to a significant cost saving in CAPEX / OPEX and enabled a smooth handover at the commissioning stage.
Long term benefits from the continued use of the BRBI and Passport initiatives. This has proven to aid the identification and prevention of failures, minimize the occurences of unplanned shutdowns, and optimization of the Preventive Maintenance & Inspection program. Realisation of these benefits and repetitive cost savings provides added confidence to stake-holders during the entire life-cycle of the facilities.
ADMA is the first and only company within the ADNOC group to roll out such an initiative and encourage proactive direct involvement and integration of the Integrity Division functions for a major full field development project. It is believed that this is also a unique approach for the MENA region by injection of decades of operational skill, knowledge and experience together with and lessons learned into the early project phases.
