South East False Creek Neighbourhood Energy Utility (NEU)

Operator Technologies provided multiple emergency solutions for this complex situation

NEU Flood

Late October 2018, flooding caused by an extreme rainfall event combined with high tide conditions and design/operational factors resulted in a prolonged outage of the sewage heat recovery system. We installed immediate mitigations to prevent further flooding. We cut an aluminum plate overnight on the water jet then installed and secured it less than 24 hours later.

NEU Remote Refrigeration Monitoring System

As the refrigeration system monitoring of the 2000lbs+ refrigerant in the heat pump room was out of commission, no work was allowed to be done until the heat pump room had gas detection installed. Our remote system was quickly deployed with our portable stands, audio/visual signalling and communications with the plant DDC. Our remote system was a temporary fix that allowed the restoration of the heat pump room. #powerofconnected

NEU Heat Pump Electrical Wiring

Every component in the heat pump room and adjacent rooms were flooded with over 20 feet of sewage. We removed the control panels and removed over 13,000 feet of compromised cable and wire. With everything stripped down and sanitized, we installed all new control panels with customized gland plates to maximize cable transiting to and from each control panel. Pulled 13,000 feet of new cable and wire, repaired and improved the cable tray system and created custom panel brackets. The project was a success, thank you to Trane and the NEU Plant Engineers and Project Managers!

NEU Refrigeration Monitoring System

With the heat pump room operational, the remote refrigeration monitoring system was removed and replaced with a fully CSA Certified, permanent Honeywell Analytics system:

7 301IRF-134A Sensors
1 301EM-RFSA Controller with Strobe/Siren
3 301EMRP-RFSA Remote PPM display with Strobe/Siren
1 301C Controller – Live system BACnet data logger with communications to plant controls
2 Vent Line Sensors
Ventilation controlled by Honeywell system.
VFD’s control supply and exhaust fans. Saving operational costs and encouraging air flow across sensors at all times.

Provisions were made for future sensors and strobe/siren locations.

24/7 Total protection for all workers and ease of mind with low level PPM detection, this Honeywell Analytics system is fully CSA certified and in compliance with CSA Mechanical room code B52.

Early Morning Start With Eagle Crane

Arriving on site in the early morning, Eagle Crane set up their Liebherr 120 ton all terrain boomtruck and led a safety meeting all while keeping on schedule. With the fans already prepped for picking, the lift went according to plan. Each fan assembly was trucked out to Karice Enterprises where we further broke down the components.

Surface Preparation and Powder Coating

With all the components broken down, they were sent for surface preparation treatment. Heavily damaged components were repaired and made stronger than before!

All Items are cleaned from oil, grease and organic matter using solvents.

Items are pickled to remove rust.

Items are washed and air dried after each pre-treatment and before chemical stripping/blasting so not to contaminate chemical immersion or blast booth.

Items are immersed in a 22% caustic soda solution at a temperature of 180-220 degrees Celsius for 1-3 days.

Items are then washed and dried.

Items are then blasted with red garnet.

Items are then washed and dried.

Items are then immersed in hydrochloric acid (HCL) then washed and dried. *Washing is a critical step as this inhibits the chemical process*

After each step is complete and passes quality inspection, each item is ready to be sent for powder coating.
