Abstract
There is an inherent risk in transitioning project personnel out and transitioning the incoming operating crew in with minimal disruption to operations and ensuring the integrity of the design. The key to mitigating this risk is to execute operational readiness assurance (ORA) processes, which provide confidence that a facility has seamless transition from design into operation, and that production targets are met in the first years of the asset's life. It is a rigorous process spanning engineering, construction, commissioning, handover, and operations; this ensures confidence in operation and asset life cost. This extended abstract focuses on a proven methodology to this aspect; it is highlighted using the Atomic Model approach, which is being implemented on the Wheatstone Processing Platform for Chevron. The atomic model consists of a nucleus (operability, reliability, and maintainability [ORM]) that provides the positive charge that will hold the whole process together; it also presents a consistent and operable asset to the operations and maintenance crew. The electrons—being the component parts—include competency, process safety, process control, operating and maintenance procedures, and maintenance management system. Together, these fully ensure operability. The enemy of ORM is complexity and the Atomic Model is a systematic approach to this complexity. Implemented by a team that views the project holistically, this approach produces a facility that is operated and maintained in a uniform manner. This consistent and disciplined approach to operations, maintenance, and reliability is the positive charge needed in the nucleus for the path towards seamless start-up.
