For JMK Engineering, project commissioning is developing tests and procedures to try and break the process within normal and out-of-normal procedures.
When the system breaks in “normal” tests, fixes must be made. For the out-of-normal failures, more has to be determined with the following questions:
- Is this is a true out-of-normal failure? If so, this should be noted but no changes made.
- Is there is a possibility that this is a possible configuration? If so, this can be addressed.
We provide commissioning services in:
- Defining the scope for commissioning
- Reviewing checkout and testing procedures
- Developing commissioning plan and proper documentation
- Witnessing the commissioning process on-site to ensure that it is executed in a predictable manner
Defining the Scope
When it is time to start the commissioning process of any new project, the scope of the project is already well known to everyone involved, but the original reason for the project as set by the higher ups may have been lost. Before setting up the commissioning plan it is a good practice to go back to the original project charter and check to make sure all the project scope items have been addressed.
We start this process during the final stages of design, when the construction documentation is being prepared. It is the best time to start the entire commissioning process as the design is complete, but the design process is still clear in the team’s mind. If we wait too long to start the process of defining the commissioning scope, the design team will have moved on to new projects, and that design knowledge will have been lost, or at least hard to extract.
Check out and Testing Procedures
Once construction has been completed, but before testing starts, all of the equipment has to be set up and I/O checked out. The procedures as to how this is completed will be different for every project and company. However the check out and equipment testing is completed, proper, written and standard operating procedures (SOPs) are critical to ensure that all the equipment and I/O is ready to be commissioned. Failing this there will invariably be situations where commissioning is held up because a transmitter wasn’t configured, or a motor had jumpers installed.
Commissioning Plan and Proper Documentation
We are huge proponents of developing a detailed commissioning plan in advance of starting commissioning and then documenting any areas of deviation in detail. This allows more thought for the process to happen upfront meaning fewer people need to be on site when the process has started, lowering costs significantly over the life of the project. Developing the commissioning plan early also allows the team to come up with ways to expedite the testing process in the way that the system is designed, for example, by adding inexpensive equipment to aid in the process like an extra terminal to make jumpering easy.
With the commissioning plan in hand, the process of going through the plan is straightforward and with all the normal and out of normal configurations thought about before hand, when there is a hiccup on site, it is easier to troubleshoot the problem.
Witnessing the process
If a client has decided to have the contractor or design engineer complete and run the commissioning process, we offer the service to review the plan and witness the process for the client. We have 5 years of developing commissioning plans and running them in a number of different industries and plant types. By witnessing the process for you, we bring our expertise and oversight to the project, ensuring that at the end you have the system that you were looking for when the project was first conceived.
