Grassroots Gas Plant
Caber personnel were responsible for the complete design and project management of a 20 mmscfd gas plant. Modifications were required as water volumes eventually increased to more than 4,000 BPD.
Grassroots Refrigeration Unit
Caber personnel were responsible for the complete design and project management (except electrical design) of an 8 mmscfd refrigeration unit.
Initially conceived as an expansion to an existing facility, the unit was eventually located downstream where all-weather access was available.
Equipment used was from inventory where possible, with little new build hardware. Extensive modifications were required to upgrade the stock unit to fit.
Total Engineering fees were less than 8% of TIC.
Co-generation Application
Caber personnel were responsible for the project management, process, design, construction, and start-up of two 2.3 MW gas turbine generation units in a co-generation application. The gas turbines were synchronized with the local utility and provide power to the Alberta electrical grid system. This project included five process exchangers that utilized exhaust heat from the back end of the gas turbines, thus eliminating the need for the gas-fired heaters that had currently been used.

Waskada Pipeline Project
An existing 6” oil transmission pipeline from a pump station to an oil shipping terminal required repair and upgrade work due to several corrosion locations.
The upgrade work included a new leak detection system (LDS) that made use of isolation valve stations in order to limit leak size should a pipeline leak occur. A new SCADA radio system was designed and installed to support the LDS in retrieving real-time data. Because the LDS required a data refresh rate of ten seconds radio system reliability and data throughput was key. The existing pipeline required new valve stations and existing valve stations were refurbished to meet the requirements of a new LDS. |

The LDS was comprised of five automated ESD (Emergency Shutdown) valve stations installed along the pipeline right-of-way. Engineering and procurement services provided included mechanical, electrical and instrumentation. Construction obstacles were resolved efficiently, enabling the Client to meet projected timelines.

Slug Installation
Caber was responsible for the process and control design required to install slug-handling capacity in one of Canada's oldest and largest gas plants. Plant staff (with Caber guidance) carried out the project, which was executed with no additional equipment and with minimal shutdowns. The project evolved from a need to meet current emission guidelines.
Amine Regenerator Plant Troubleshooting
Caber investigated an amine regenerator plant that was overflowing amine into the atmosphere from the tower overhead vent line. It was concluded that the regenerator trays were plugged due to calcium carbonate scaling. Caber hired a mechanical crew to replace the trays and to supervise the installation of the new ones, including plant start-up. The regenerator plant was back to full capacity in less than two weeks’ time with improved efficiency, increased production capability, reduced environmental impact, and decreased operating costs.
