Risk-Based Work Selection - Key to Optimized Turnaround Workscopes

Operations and Maintenance Practices in refineries focus on maximizing safety, reliability and profitability, in a highly competitive industry, with tight margins. A key consideration is to effectively manage annual maintenance costs which can be as high as 40-50 MM$/year for a medium size refinery. These costs can escalate to several hundred million dollars, if unplanned shut downs occur, resulting in loss of production. Risk-based work selection (RBWS) is used to plan, schedule and execute maintenance work and is an industry Best Practice for improved reliability. The result is a risk-justified, optimized work list which uses maintenance resources cost effectively while mitigating unacceptable business and S/H/E risks. For TAs which require 200,000 to 1,000,000 person-hrs, the process has identified potential savings of 15-30% on estimated direct costs for the planned work scope. RBWS is used for task prioritization for turnaround (TA) work scopes and routine maintenance work. Rigorous use of RBWS enables effective use...

Machinery Hurricane Flood Damage– Innovative Seal Recovery Procedure

Serious floods rarely occur in the life of a refinery or petro-chemical plant. But when such an event does occur there are significant implications for the reliability of rotating equipment and associated business risks when it's time to restart the plant. And because this scenario is so uncommon, there are few, if any, industry standards offering guidance or practical advice on the methods appropriate to ensure a cost effective and reliable restart of the facility. Two Becht Machinery Advisors, Stanley Fussell and Randy Passman, developed an industry-unique and innovative procedure for flushing and testing oil film and gas seals that allowed a client to successfully restart over two dozen major machinery trains following a serious flood, without having to replace a single seal system.The experience involved the serious flooding of a large chemical plant due to hurricane surge. The entire plant was submerged in up to ten feet of salt water...
