Abstract

Run-to-end (hereafter referred to "RTE") is a fit-for-purpose approach to manage late field life assets for realization of full potential through safe, reliable and cost effective operation by maximizing value at the end of economic life while complying to minimum technical standards through ALARP demonstration. RTE provides an overview of the multiple processes which shall be adopted and customized to the business needs of the intended facilities with the aim to minimize value leakage and ensuring safety until facility's cease of production prior to relinquishment or decommissioning. This RTE philosophy is to be applied to facilities that are within 5 years of its end of economic life so that value leakage can be minimized within the tolerable risk. The RTE provides an overview of development of case for change, guided process for the Operation & Maintenance philosophy changes and demonstration of risks mitigation & governance assurance. The safety risk of the facility shall be assessed and monitored through continuous ALARP demonstration. If the facility is deemed to be either no longer safe through ALARP or can no longer maintain a positive cash flow position, it is recommended that the facility to cease production operations and proceed with relinquishment or decommissioning activities. It has been implemented in one of late field life and resulting to 30% reduction of OPEX.
