prompt field workers for on-the-spot diagnostics and field workers can speak with maintenance staff or others to receive focused direction. Te most dramatic savings to date have been
downstream. Estimated savings are in the US$2 to US$3 million range per 100 000 barrels per day (bpd), a result of closing operating performance gaps through improved mechanical availability (Fig.1). Companies integrating mobile data-logging technology with decision-support technology achieve such results through a combination of factors, including more cost-effective regulatory compliance, better energy management and execution of best practices through intelligent procedures in an easy-to-follow decision tree form on rugged HazLoc-certified mobile computers. Te hard-dollar savings are achieved through a 1–5 per cent gain in operating efficiencies, depending on the initial baseline and assuming an approximate two percent reduction in a site’s overall maintenance budget. Operator driven reliability (ODR) is the single
largest area of improvement. A typical refinery might operate with more than two million data points yearly, 2–5 per cent of which might run outside of their defined operational envelope,
making maintenance and monitoring more difficult and costly. Empowering maintenance personnel with mobile data-acquisition devices could enable these refineries to reduce the number of outlying data points by 1–2 per cent, providing plant personnel with more immediate, more reliable information on equipment operations. Some major refineries have documented
savings of more than US$500 000 annually per site. Other high-payback equipment categories include compressors, couplings, exchangers, fans, gears, motors, seal pots, towers and turbines. Although upstream is a little behind refining in adopting mobile solutions, benefits are emerging here as well, mostly in onshore and offshore production, LNG plants and pipelines. Based on an upstream production margin of US$30 per barrel of oil equivalent (BOE), some mobile solutions can deliver annual returns of US$2/BOE or more. Te latest version of IntelaTrac supports
dynamic procedures to improve asset responsiveness, from weather to changing business conditions. Empowering the mobile field workforce with a multi-tasking and intelligent mobile solution enables them to consistently execute best practices and continually close performance gaps. l
