- More than 72 hours of estimated down time saved during cutover
- Reduced hardware footprint
- Simplified Maintenance
- Reduced design time
- Space Savings
Rather than continuing with this exacting design, engineers on the R.E. Mason team started thinking about different solutions entirely.
After the decision was made to change course, the design of the system became simpler and fewer hours were being spent on integration challenges. The new design drastically reduced clutter, disposed of peripheral devices, and freed up floor space.
Once designed, the installation approach changed entirely. Rather than focusing on the existing DCS cabinets we now concentrated on the existing safety barrier cabinets. These cabinets are where we would house the majority of our new DeltaV I.S. equipment, removing the existing DCS cabinets from the picture. Space was saved and installation time decreased by an estimated 72 hours.
Without having to deal with multiple devices and terminations, maintenance on the system would become a less daunting task. The instrumentation group can now run a signal directly from the DeltaV system to the field instrument. There is no more worrying about grounding issues or low voltage at the device. All of this is eliminated with the use of I.S. CHARMs due to higher voltage on the safe side and galvanic isolation between the field and DeltaV.
Considering the reduction in design time, the time saved in installation labor, space savings, and future maintenance, the I.S. CHARMs solution can become appealing to both the integrator and the end user.
The solution needed to make sense financially without affecting schedule. The I.S. CHARMs solution had come up in the past but was dismissed because of the price tag. It wasn’t until we began seeing how much time and effort we were putting into our old design that the cost of I.S. CHARMs became justified. We were also convinced that the new I.S. CHARMs solution would benefit the customer in a big way.
