Instrumentation & Controls Experts

Have you ever completed your project but when you went to commission the system, it didn’t work? Equipment was damaged? Flow and temperature readings were off? Project delays, your reputation suffered, costs ran over?

Instrumentation is all about knowing the details, many little details. To do that, you need a company that has a depth of experience and understanding of the interplay between pipefitting, instrumentation and electrical trades in order to calibrate or install control systems in a range of industries.

Our techs have that experience and know how to install stainless steel tubing, field instruments, electrical systems and calibrate equipment. Many people don’t think of other small details: mounting position, tubing slope, protection of sensitive devices, quality and turn-over documentation.

There’s more. The system needs to communicate. We have the technical skills required to loop test and function test equipment, commission systems and resolve issues with integrated process controls, SCADA systems and PLCs.

Many people can do portions of this work. But our team will do it all and make sure it works – the first time.

Grace has recently expanded its services to include electrical and other technical skills. Want to know more? Give us a shout.

Energy & Power

Aecon – TC Energy – Napanee Generation Station (2017-2020)

Sub-contracted to AECON during the construction and commissioning of the 900 MW natural gas combined cycle. The scope of the work included the installation of 1800 balance of plant Instruments including stainless steel impulse lines and pre-insulated sample lines. Our scope was also expanded to the re-assembly of the various critical control valves on site that had to be disassembled for welding and the various steam blows required during start-up. We also worked closely with Mitsubishi to facilitate the installation instrumentation of the gas and steam turbines.

During the commissioning phase our team of instrumentation technicians worked closely with commissioning leads to loop check all sensors and instruments that fed back into the SCADA system. Our team calibrated all instruments that were required by the client to meet regulations. We provided around the clock coverage to trouble shoot during start up to ensure successful operation of the plant.
