electronic Work Package (eWP)
DataGlance eWP provides an effective method to improve productivity and efficiency and lower the cost of the overall work management process.
For many years there has been a steady accumulation of improvement initiatives, controls and work practice barriers integrated into the overall work management process. While these initiatives, controls and barriers have resulted in reducing worker errors and plant events, the cumulative impact of these additional barriers has also resulted in significant productivity reductions and has increased the overall costs to operate and maintain power plants.
Why DataGlance eWP?
Experience – Clinton Station made U.S. nuclear industry history on Tuesday, July 29, 2014 when a nuclear work package was completed electronically, from start to finish, for the first time. DataGlance eWP is the only eWP solution in full production at commercial nuclear plants. Today, DataGlance eWP is used at 11 nuclear plants (19 units) with over 40,000 eWPs completed and more than 1,000 daily users. Additional eWP projects are in progress and planned for 2016 and 2017.
- Proven DataGlance framework technology, eWP application and implementation process
- Increasing user base – estimated over 1000 users daily with over 40,000 completed eWPs
- Real world user feedback results in continuous application improvements
- On schedule on budget project delivery track record
- The application can be configured to meet specific business process work flows without the need for source code changes
- Application configuration provides customers a powerful, long term and cost effective tool to control, modify and expand functionality without the need for expensive source code changes
- Mobile device agnostic
Detailed Work Flows and Integration
- Baseline work flows are the “starting point” and are easily modified by configuration to meet various business needs without the need for application source code customizations.
- EAM system interfaces are developed and maintained to allow eWP and EAM key status and data exchange information to be synchronized where needed
- As part of the eWP process, detailed business process documents will be generated to document the new as configured work flows which are the basis for testing and training materials development.
Delivering the Nuclear Promise
America’s nuclear energy facilities have launched a multi-year initiative to safely generate electricity that the nation uses more efficiently and economically. The initiative was announced in December by the Nuclear Energy Institute (NEI), which is coordinating the multifaceted effort in tandem with member electric utilities and member power producers – including the Institute of Nuclear Power Operations (INPO) and the Electric Power Research Institute (EPRI).
The initiative, titled “Delivering the Nuclear Promise: Advancing Safety, Reliability and Economic Performance,” comes with nuclear energy facilities operating at sustained high levels of safety – as documented by an array of performance metrics – but earning less revenue during an unprecedented era of low natural gas prices and subsidies for other electric sources.
As part of the initiative, the industry will analyze cost drivers common to all nuclear power plants and recommend programs and processes to improve their efficiency and effectiveness. The goal is to identify innovative solutions by 2018 that will enable plant operators to significantly reduce operating expenses.
The eWP Value Proposition
DataGlance eWP customers who have taken the initiative to implement eWP projects performed eWP value assessment (business case) studies. These studies concluded that implementing eWP projects are very cost effective and expect return on investment in less than two years.
The eWP “value calculator” is a DataGlance developed detailed Excel spreadsheet that was used to calculate eWP dollar savings which can be used for a typical eWP nuclear business case development. The eWP value calculator can also be used to identify high value target areas to help focus the initial project go-live scope to achieve overall optimum eWP project benefit. Below is an example figure generated by the value calculator to display the individual savings category and total annual savings as a result of specific parameter inputs.
The eWP value calculator provides a detailed review of the potential savings from 17 different business processes related to the implementation of electronic Work Packages. For each category the savings are estimated based on a formula that includes “global” and “category specific” variables. Examples of global variables include; average number of work packages per unit per year, average labor rates for various labor types, number of units, etc. Category specific variables include; estimated time saved by process automation, distribution of effort across various personnel job types, percentage of work packages affected by the process change, etc.
The calculator also supports the ability to enter a value range for each particular input value. By allowing an “expected”, “low” and “high” estimate for each input, the calculator provides a range of savings for each category showing the sensitivity of the category savings to each expected, low and high assumption. Finally the calculator supports scenario analysis by varying two global variables that have an impact across all categories. These two global variables are the fully loaded labor rates and average number of Work Packages worked per year per unit. Since the value calculator is a live-dynamic tool, a range of values can be used and the effect of the value ranges can be analyzed quickly.
The results provide a baseline expected annual savings estimated bracketed by a low and high estimated savings. The baseline saving is then compared against 4 alternative scenarios with high and low labor estimates and high and low work package estimates.
How Does it Work?
Planners plan work packages using the existing EAM system. Once the work package is completed by the planner, this status change triggers the process to assemble the work package electronically, create the eWP and send it to the eWP server for either further review or assignment.
Craft personnel then “check-out” the master eWP from the server to the mobile device. Once the eWP is checked out to a mobile device, the eWP can be worked without needing connectivity to the eWP server.
Craft personnel perform the task using the same procedure use and adherence techniques, only with a stylus in lieu of paper. Upon completing of the task, craft check in the completed eWP for post work supervisor review, operations post maintenance testing and eventual electronic QA record archival.
The key to eWP success is the ability to manage the eWP throughout the entire work flow process, from creation, assembly, review, authorization, assignment, revision, execution, task tracking and monitoring, closeout review, data transfer, QA record generation and finally archival.
