Genentech’s focus on implementing a performance-based monitoring strategy led the company to a non-invasive wireless monitoring solution. By implementing the solution on steam traps and critical research equipment, Genentech was able to improve its asset management strategy, find energy savings and improve uptime.

Genentech’s mission is to meet unmet medical needs. One of the goals in the Corporate Facilities Services group is to operate a world-class facility. The key focus area to achieve this goal is continuous improvement of facilities and maintenance systems to reduce operating costs. By driving down operating costs, more funds can be allocated to developing the product pipeline and achieving the mission. 

The guiding principles for identifying and executing continuous improvement projects include:

  • Improving plant asset management by implementing a performance-based maintenance strategy. Genentech has a well-established, time-based asset maintenance program. Transitioning to a performance-based strategy will also allow Genentech to predict equipment failure and understand an asset’s life cycle.
  • Reducing energy costs. Identifying methods to improve the efficiency of energy consumption will reduce energy costs and improve the bottom line.
  • Improving uptime. Research and operations expect the facility and equipment to be functional and reliable. Any downtime in the facility directly impacts the bottom line. Corporate Facilities Services focuses on improving uptime and equipment reliability to help achieve the mission.

Genentech identified several assets that could benefit from a performance-based maintenance strategy to reduce energy costs or to improve uptime.

  • Steam Traps. Genentech has an annual steam trap maintenance program. However, throughout the year, steam traps often fail. Steam loss from failed traps was estimated to cost the company hundreds of thousands of dollars annually. Steam trap failures could be prevented or found as they occur using a steam trap monitoring system, resulting in significant energy savings.
  • Critical Research Equipment. Ultra-low freezers are critical to research activities. Reliability issues with older stand-alone freezers result in downtime and potential loss of work product. Maintenance activities are performed more frequently to avoid these issues. Performance-based monitoring of these research freezers would allow the maintenance staff to proactively detect issues and prevent failures. This would result in increased freezer uptime and could potentially extend the useful life of the freezers.

The challenges with implementing performance-based maintenance on existing systems include cost and invasiveness. In order to monitor the condition of assets, analog instruments must be replaced or new instruments must be installed to collect data. Traditionally, this work is invasive and requires a process interruption and engineering oversight. Furthermore, the new system must be commissioned for restart. This often includes inspections and leak checks, as well as revalidation in order to return the system to service. These activities often result in an unfavorable cost/benefit ratio.

As a cost effective alternative, Genentech identified a non-invasive monitoring solution, provided by Cypress Envirosystems. Devices are clamped onto existing instrumentation to collect and wirelessly transmit data to a server for trending and alarming. This method eliminates the need for process interruption for installation and minimizes engineering oversight. Table 1 below shows the comparison of monitoring solutions.

  Traditional monitoring Non-invasive wireless monitoring
Plant disruption •   Invasive
•   Process interruption required
•   Wiring required

•   Non-invasive, clamp-on devices
•   No process interruption
•   Minimal wiring

Reliability •   Power source required
•   Real-time data collection
•   Battery operated
•   Pre-programmed data collection rate
Engineering •   Changes existing system
