facility and are required to operate safely. There are many factors to consider when providing an asset life extension solution to aging offshore or onshore facilities. This chapter presents the key issues to consider and a prescribed methodology follow in justifying asset life extension for an aging facility. At all stages of the asset life extension, assets are required to satisfy the As Low as Reasonably Practicable criteria as a minimum for each discipline and demonstrate fitness for purpose.
