Executing a risk analysis for a booster pump station along with the introduction of strEAM+, MaxGrip identified opportunities for significant maintenance cost reductions at the San Francisco Public Utilities Commission (SFPUC).
SFPUC provides retail drinking water and wastewater services to the City of San Francisco, wholesale water to three Bay Area counties, green hydroelectric and solar power. It is SFPUC’s mission to provide customers with high-quality, efficient and reliable water, power, and sewer services in a manner that is inclusive of environmental and community interests. In 2015, MaxGrip and SFPUC agreed to implement the Asset Performance Management software strEAM+ to enable the SFPUC wastewater division’s asset management program.
The MaxGrip turn-key solution for risk management offers an effective method to identify the necessary balance between asset performance, risks and costs. In order to mitigate risks, they first have to be identified and assessed. Although the booster pump station did not seem like the obvious place to start, it is a critical piece of SFPUC’s wastewater infrastructure. During wet weather events, three out of four pumps must be operational to handle flows. However, should they fail, the risk of illegal discharges goes beyond environmental impact and can lead to violations of operating permits, steep fines, and significant reputational risk.
MaxGrip project manager Hans Franck: “Using our Asset Libraries, with 20-years of reliability data, we managed to perform the analysis utilizing 30% fewer resources of SFPUC. Our recommendations addressed the most critical risks and maintenance issues. Technical back-up and protection systems have been added, and critical maintenance tasks are performed to reduce risks. In addition, the risk analysis for the SFPUC booster pump station helped reduce non-critical and costly.
The analysis quickly generated sixteen new maintenance plans to increase reliability, but also an expected reduction in preventive maintenance for non-critical equipment. This leads to a theoretical reduction of 25% of the maintenance hours every year with expectations of even greater results following future analysis.
MaxGrip, along with strEAM+ complement with SFPUC’s existing business objectives, risk reduction goals and total cost of ownerships benchmark targets were all successfully achieved during the first analysis at SFPUC. The analysis included a pilot of strEAM+ in a hosted cloud environment. SFPUC staff described the software as user-friendly and straightforward, and are now looking to embed strEAM+ directly into their own IBM Maximo environment.
Looking ahead, full implementation of strEAM+ and wider adoption of RCM principles will continue to generate valuable data. The stronger the insights into real asset performance, the stronger the ability to foresee and avoid incidents that impact safety, quality, service levels, and costs. The collected data are the building blocks of improved maintenance strategies. strEAM+ compares maintenance plans and mitigating actions while guaranteeing safety and enabling optimization.
With strEAM+ embedded into Maximo, SFPUC can easily translate their new maintenance strategies into the day-to-day schedules, and also monitor how the assets relate to all applicable legislation. The software visualizes critical regulated assets in daily work orders and identifies potential compliance issues.
