Horizontal Directional Drilling
-
Northern Courier Pipeline: Dover River
Product Pipe: 42"
Max Ream Size: 60"
Length: 1184m
Date: 2015
The spring thaw caused the ice roads to become unusable. A special bentonite based fluid was circulated through the bore to hold it open over the course of 8 months before drilling could resume.
-
Northern Courier Pipeline: Athabasca River
2016 Northwest Trenchless Project of the Year
Product Pipe: 42"
Length: 2195m
Date: 2015
This crossing set the record for a HDD of this size in Canada
-
McLoughlin Point Wastewater Treatment Plant
Product Pipe: 42"
Length: 940m
Date: 2021
Extremely hard rock made this project very difficult. The fluid system was designed to reduce wear on the tooling and maximize ROPs.
-
Imperial Oil: Waterdown to Finch: Hidden Lakes
2022 Trenchless Technology: Project of the Year Runner Up
Product Pipe: 12"
Ream Size: 24"
Length: 3531m
Date: 2021
Record setting length for an HDD for a 12" pipe installation. Due to the length, friction loss and carrying capacity of the fluid were vital in the success of the bore. 1 of 37 successfully completed HDDs on this project.
-
Vancouver Airport Fuel Line
Product Pipe: 14"
Longest: 780m | 18 urban & semi-urban HDD crossings
Date: 2021
High risk of settlement of surrounding structures and strict limitations due to the urban environment.
-
Pembina: Athabasca River
Product Pipe: 30" / 22"
Length: 1181m / 1116m Parallel Crossings
Date: 2021
Very heterogeneous conditions throughout the bore path along with a large elevation change between exit and entry. Oilsands, limestone, Clearwater shale and clay till formations made up the bore path.
-
Trans Mountain Expansion Project
Product Pipe: 36"
Longest: 2256m | Major Crossings: 40
Date: 2020-Present
Highly varied geologies, environmental restrictions, and unforeseeable events created many challenges on this project. Successfully completed.
-
Alberta Products Pipe Line
Product Pipe: 12"
Longest: 633m | Crossings: 21
Date: 2018-2019
These crossings involved traversing multiple creeks, rivers, and transportation routes. High plastic clays and shale zones were present throughout the project.
-
Keyera: KAPS
Product Pipe: 12"/16"
Longest: 2256m | Crossings: 40
Date: 2020-Present
These crossings involved very high plastic clay tills with multiple sections of highly reactive and fractured shale. Highly fractured shale and sandstone made circulation loss a major problem. Utilizing our chemical clay inhibitors, the crossings were completed without incident.
-
ATCO:
Product Pipe: 12"/16"
Longest: 2256m | Crossings: 40
Date: 2020-Present
Multiple crossings in the Calgary area in both high traffic and urban sections along with more rural crossings. Highly unconsolidated fill zones were present within the urban right of ways. This made bore stability challenging. High plastic clays and coal were also present along these bore paths.
Direct Steerable Pipe Thrusting (DSPT)
-
Trans Mountain Expansion Project
Longest: 662m | 11 Crossings
Date: 2020-2022
Varied geologies and major elevation changes made designing and implementing these crossings difficult. In addition, due to the size of machines being used it was necessary to remove the larger casing around the product pipe and inject a novel bentonite stabilizing fluid into the void space.
-
Coastal GasLink
Longest: 680m | 4 Crossings
Date: 2020-2022
Highly abrasive and porous unconsolidated geologies required a specially designed slurry and lubricating fluid for successfully traversing these crossings. Heterogeneous geologies made up a large portion of the project requiring a versatile system capable of adapting to the changing conditions.
Pipe Jacking
-
City of Calgary: Rangeview Sanitary Trunk: Dr 1
TAC Project of the Year Under 100 Million
Longest: 926m | AVN 1500 | 3 Drives
Date: 2020
This drive was completed with high plastic clay till containing multiple sand seams. The annular fluid used, reduced jacking forces greatly allowing for the quick advancement of the tunnel.
-
Trans Mountain Expansion Project: Jacko Lake
Longest: 1312m | AVN 2000 | 4 Drives
Date: 2022-2023
Long drives through highly abrasive bedrock with sand/clay till pockets. For successful drives a high quality lubricating fluid is required to minimize jacking forces.
-
Coastal GasLink: Morice River
Length: 886m | AVN 1800 | 1 Drive
Date: 2022-2023
Long drive with both unknown and very heterogeneous geologies to be encountered. The final length of the drive involved an uphill climb with heavy tunnel segments. Strict environmental restrictions were put on the design of the fluid systems resulting in alternative formulations being used to ensure the success of the project.
-
City of Edmonton: Malcolm Tweedle & Edith Rogers Dry Pond & Sanitary Upgrade
Trenchless Technology Project of the Year 2023
Date: 2020-2021
Highly reactive clay and shale geologies were addressed to eliminate cutter clogging, mud solids content and prevent squeezing on the tunnel segments.
