Don’t Risk a Poor Asset Hierarchy
The Importance of Accurately Identifying Your Equipment and Assets
Why is an Asset Hierarchy Important?
You may ask, “Why should I take the time and trouble to put my equipment and assets into a logical hierarchical order?” We believe it is well worth the effort to create an equipment hierarchy structure that allows for the following:
- Work identification/management, including preventive maintenance prioritization
- Maintenance cost accounting
- Failure tracking
- Asset delay/downtime information
- Spare part/individual component management
Creating an asset hierarchy also involves creating a standardized set of naming conventions (taxonomy) for labeling your equipment and assets. Finally, housing all this data in a Computerized Maintenance Management System (CMMS) allows for centralized tracking and reporting.
What are the Benefits of Creating an Asset Hierarchy?
A good asset hierarchy:
- It allows you to track costs and failures at any level of the organization. It allows you to analyze costs by department, system, specific equipment, and individual component. It allows you to write work orders to specific asset levels instead of creating them at the location level, preventing meaningful analysis.
- Supports proper capital planning, asset health, risk assessments, production loss analysis at the causing asset level, and production and cost control improvements.
- Enables reliability performance analysis and improvement at the asset level (asset strategy development, implementation, and analysis, life cycle costing, repair vs. replace, bad actor analysis, MTBF, MTTR).
- Underpins accurate costing, profitability, budgeting, and depreciation.
- Allows engineering for standardization and engineering design based on asset performance, reliability, and cost performance.
The oil and gas industry has developed an equipment hierarchy pattern documented in the ISO 14224 standard. This is a recommended method for organizing assets logically and consistently.
Different industries or companies will have different needs; therefore, hierarchies and naming conventions should be customized to reflect your facility operations best. The critical thing to remember is that any item that may be worked on should be captured in the CMMS; otherwise, how can you report on its condition and conduct effective maintenance?
There are several ways to organize your hierarchy data effectively. The different methods of organizing the hierarchy include:
- By System: facilities – plant compressed air system
- By Equipment Type: all fork trucks, AHUs
- By Product Line: discrete production areas
How can I Get Started Creating an Asset Hierarchy?
Evaluate Your Current Asset Hierarchy
You can get started by evaluating your current asset hierarchy in your enterprise asset management (EAM) system in accordance with the ISO 14224 standard shown above. The master equipment list should include taxonomies assigned to the equipment and specification data, including manufacturer, model number, and serial number, as determined by vendor documents or nameplate data.
Standardized Naming System
Using a CMMS, you can set up consistent naming of equipment and assets so they are easy to find and view related data at a glance. This can be a simple exercise, keeping the following best practices in mind:
- Be logical, consistent, and unique
- Avoid duplicate data
- Leave room for growth
- Prioritize the use of letters over numbers (or a combination of both that MAKES SENSE)
What a CMMS Provides
The automated capabilities of a CMMS provide a way to gather asset data for driving equipment reliability and process improvement. Without reliable asset data, it is difficult, if not impossible, to effectively allocate already scarce maintenance resources. Poor asset data leads to making decisions based on whatever is causing the most pain today.
Once Your List is Complete, Use It
Having a complete equipment hierarchy defined isn’t enough, and it is a waste of time if you don’t use it. Once the hierarchy is complete, an effort to prioritize the equipment should be performed. Root Cause Analysis (RCA) and Failure Mode and Effects Analysis (FMEA) can be helpful tools to assist with your prioritization efforts.
This will allow you to prioritize the work execution efforts to organize and prioritize the efforts of the maintenance department more efficiently and effectively. It also helps set priorities for preventative and predictive maintenance activities, allowing for early identification of problems and their resolution BEFORE a production stoppage occurs. Ultimately, this helps create a safer workplace with fewer HSE incidents.
Conclusion
Having a well-organized hierarchy can significantly enhance your reliability efforts. It is the foundation of any successful maintenance and reliability program. A comprehensive equipment hierarchy is the backbone of any CMMS (otherwise known as an asset management system). It’s an essential step towards achieving condition-based maintenance tasks and a more reliable operating environment to be more competitive in the marketplace.
