M&R History (recent incidents) Explosion in Waste Heat Recovery unit at LNG Plant • Production shutdown • Initial loss: US $40 million / week Root cause: Thermal fatigue and material embrittlement caused by poor weld quality ? ? ? ? Slide

M&R History (recent incidents) 2010 Deepwater Horizon (BP) oil spill • Casualties: 11 dead • Spill: 4. 9 million barrels of oil Root cause: • Wellhead blowout. • BP’s management process did not adequately identify or address risks created by late changes to well design and procedures. • Better management by BP, Haliburton and Transocean would almost certainly have prevented the blowout by improving the ability of individuals involved to identify the risk they faced, and to properly evaluate, communicate and address them ? ? ? ?

Potential Root Causes Industry experts have identified a number of root causes for all recent incidents • Deficiencies in inspection & maintenance procedures/ programs • Unreliable and inadequate process control equipment • Inadequate Asset Management System ? ? ? ? Slide

Asset Management "Systematic and coordinated activities and practices through which an organization optimally and sustainably manages its assets, and asset systems, their associated performance, risks and expenditures over their life cycles for the purpose of achieving its organizational strategic plan". (Institute of Asset Management / British Standards Institute PAS 55: 2008) ? ? ? ? Slide

Asset Strategy An ASSET STRATEGY management system is the framework of processes and procedures used to ensure that an organization can fulfill all tasks required to ensure the asset delivers on its intended purpose • • A key milestone towards PAS 55 / ISO 55000 compliance A third generation maintenance & reliability methodology A risk based approach A proven asset management methodology − Implemented over 150, 000 assets ? ? ? ?

Benefits of Asset Strategy (Utilities Case study) • Coke Boiler 1 reliability improvement − − All maintenance/ inspection strategies and one time changes such as waterwall (boiler tubes) modification has been implemented Boiler 1 in October 2013. No forced outages due to tubes has occurred for the last 24 months. Based on historical records, 6 tube failures are expected every 24 months. With a clean history for the past 24 months, $8 M has been saved for 1 boiler. Implemented for 4 coke boilers • Safety Improvement − Devolved Burner Management System (BMS) based on the SIL Analysis to improved process safety • Operational Discipline − Due to the large amount of procedures for a complex plant, it was difficult to extract a specific procedure for a situation/occurrence. − Developed Procedure Sequence Flow Diagrams that capture all relevant operating procedures for each system in a single diagram that provided a clear visualization of the complete process to improve operational discipline. ? ? ? ?

Benefits of Asset Strategy (Utilities Case study) • PM Clean up ‒ The deletion of 900 PMs that were not linked with failure modes , resulted in an annual savings of $5. 4 M. • PM Optimization − Prior to asset strategies, Over a period of 10 years, an average of 7, 000 work orders were released each year. In last two years 4, 200 work orders are released − Recalculated Safety Integrity Level (SIL) based on 3 years Proof Testing Interval (PTI) in order to align with Shutdown schedule. Ø By changing PTI to 3 years from 2 years, still plant can achieve required Risk Reduction Factor (RRF). Though Safety Instrumented Function (SIF) is reduced but required Safety Integrity Level (SIL) is still met or exceeded • Pre-defined work scope improve work execution ‒ ‒ ‒ Over a period of 10 years, an average of 7, 000 work orders (both planned and corrective) were released each year. 900, 000 ours to develop work scope : assumptions: 2 procedure, 1 check sheet, 1 SAP task list required for each work orders and each activities (e. g. writing a procedure ) take 4 hour Now maintenance procedures and check sheets are in place and readily available to execute work resulting elimination $ millions / year from the maintenance budget ? ? ? ?

Back up slides (Definitions) • Preventive Maintenance (PM) An equipment maintenance strategy based on replacing, overhauling or re-manufacturing an item at a fixed interval (e. g. time and/or distance), regardless of its condition at the time. Car servicing at every 6 months or 6, 000 KMs whichever comes first Condition Based Maintenance (CBM) Maintenance activities that are based on measured condition of an asset against predetermined tolerances with no further analysis or decision being needed. If the measurement value exceeds the predetermined tolerance, then corrective maintenance activity is triggered, without question. ? ? ? ? Slide

Back up slides (Definitions) Predictive Maintenance (Pd. M) An equipment maintenance strategy based on measuring the condition of equipment in order to assess whether it will fail during some future period, and then taking appropriate action to avoid the consequences of that failure. The condition of equipment could be monitored using Condition Monitoring, Statistical Process Control techniques, by monitoring equipment performance, or through the use of the Human Senses.
