Standardization and automation of procedural operations based on the best practices of experienced operators realizes safer operation and improved profitability.
Process plants of all types are dominated by procedural activities that are critical to achieving safety and efficiency. These procedural activities come from many areas, including manual SOP's, legacy control systems and the tacit knowledge that operators have acquired through years of experience. With a high retirement rate in senior operations personnel, significant and valuable knowledge is being lost, and the new generation of engineers and operators are at a loss.
Inadequate availability of accurate procedures can lead to operation errors. With an emphasis on plants running at optimal efficiency and continuous vigilance on safety, it is critical that the operational knowledge and best practices are captured by the enterprise and are executed consistently and accurately.
Industry leaders have recognized that there is a need for a standard around automating procedures and have formed the ISA-106 committee whose purpose is to develop standards, recommended practices, and technical reports on the design and implementation of procedures for automating continuous process operations. Yokogawa has been involved in this standardization effort and has developed a solution offering that address the issues covered in the emerging standard - Modular Procedural Automation.
Have you ever concerned about senior operators retiring? Can your workforce maintain procedural operations of your plants safely and efficiently after experienced operators are retired? Many plants rely on experienced process operators to deal with the procedures, and as long as they are around, it may not be a big problem. However, given the demographic problems with aging workers and hard to find replacements, this type of dependence is becoming ever more perilous.
Besides aging workforce issues, safety should be another continuous challenge for your plants. Operational safety still depends on operators, which are human: they may follow operating procedures under pressure, interpret the same written procedure slightly differently, and perform them a little differently. Significant incidents have occurred due to poor procedural operations as a result of human error, not mechanical failure.
Companies have invested in automating operational procedures but they often do not achieve operational or safety improvement goals because of the following reasons:
- They often use programming tools in a legacy control system that is difficult to use.
- Programmed procedures are often written with minimal structure and documentation.
- Programmers of original procedures are often not available to implement updates and modifications.
- It is difficult for others to understand the code and make changes.
- A single operator may have hundreds of loops and thousands of indicators to cope with.
Consequently, the operational staff of the process unit will go back to using manual procedures out of frustration and inflexibly of the automated procedures.
Our consultancy is based on a long and diverse track record in many industries and processes. In 2000, Yokogawa introduced Exapilot, the world's first automated procedural control solution. Exapilot is an online navigation tool that guides operators step by step through plant operating procedures, and is now installed in over 1,000 plants around the world. The capabilities of MPA include:
Vigilant Procedure Consulting and Tools
Best in class tools, capabilities, & consulting expertise of embedding procedure implementation modules into the control system architecture based on operational requirements.
MPA consultants and engineers are experts at capturing and documenting currently used procedures whether they reside in a manual, legacy control system, or in the mind of the operator.
Standard based design on the emerging ISA-106 standard work/development methodology assures that your procedural investment will remain reliable and pertinent to operating staff.
Advanced Decision Support Integration
Procedures are integrated into high performance HMI and alarm systems to provide operators a high level of situational awareness in all process conditions and states.
MPA's value is enhanced by integration and deployment of an operator training system to train plant operators to initiate appropriate responses to abnormal conditions and efficient execution of process transitions.
This combination of consultancy skills and world leading applications provides the optimum solution to integrating procedural control, operator actions and the control system into a unified environment for a best practice plant operation.
Modular Procedural Automation combines consulting expertise with world class procedure control capabilities to:
- Capture, optimize,and retain procedural knowledge and control in a process plant
- Implement procedures at appropriate level in a plant control system to meet procedure reliabilty and flexiblity requirements
- Integrate procedures into operator interface and alarm system for improved situational awareness
Exapilot is an online procedural automation tool that guides operators step by step through plant operating procedures. Since Exapilot was first released, over 1,000 licenses have been sold to companies all over the world, and the majority of users have come from the chemical, petrochemical, and oil & gas industries.
Exapilot Software Features:
- Operating procedures are represented as combinations of icons (during configuration)
- Avoids missed steps (during operations)
- Automating DCS operation and monitoring
- Seamlessly connecting with production control systems
- Documenting standard operation procedures (SOP)
- Making more effective use of your most skilled operators
Williams Opal successfully reduced start-up time of stabilizer column and turbo expanders with Exapilot.
Exapilot also standardized operators' start-up processes as Standard Operating Procedures.
