Edmonton Legislature Building- Power Upgrade

Short ones are the tricky ones.  

Tracking used: #ParaTrack2  
Location: Downtown Edmonton, Alberta, Canada  
Distance: 250m (820 ft)  
Depth: 20m (66 ft)  
Horizontal Curve: 19.23deg  
Entry Angle: 13deg  
Exit Angle: 4deg  
Ground: Sand/Gravel/Clay  
Pipeline: 18inch HDPE  
Technique: #MudMotor (90%) and #Jetting (the last 10%)  

We were contacted to do a special project for which was #complex in nature. The project was in the hustling bustling downtown area of Edmonton City.   

A Power #Upgrade required 2 power lines to be installed under the Alberta Legislature Grounds. Both drills were designed to have 4m lateral separation. Tight spaces were the prime feature of this job.   

An entry pad was specially built which could only accommodate the drill rig & nothing else. The Exit point was located 3 floors down in a Car Park. 32-inch-wide holes were tactically drilled out of the concrete of the parking wall, to enable the BHA to poke through.   

There was no room for error. The challenge was accepted and both times we hit the target dead center. The combination of compound curves and constantly changing ground geology added to the challenge. Together with the dedication and teamwork of Omni Directional Boring LP and Prime Horizontal, both bores were completed, and the product was pulled in safely.

Hadelner Canal HDD Crossing

Transporting #wind gained electricity under the Elbe-Weser Waterway

 

 

 

 

Despite the interference due to frequent flow of traffic of boats throughout the whole crossing, the team was able to successfully perform a HDD crossing under the Elbe-Weser Waterway by means of #ParaTrack2 in combination with the Surface Coil.
A 20-ton Ditch Witch rig was set up parallel to the road and barley field. 50m of surface coil was laid down at entry and 60m at exit side. The formation was soft soil and clay, so a 3” Jetting assembly and a 6” jetting shoe was utilized to drill at depths of 6 meters under the canal.
The objective was to pull wind #energy electric cables underneath the waterway for transport of wind gained electricity. The entire process was completed in just 2 days, well done to the team involved!

Bringing Renewable Energy to Breydin, Germany

Kudos on yet another job well done #PrimeHorizontal Europe!

A different but not unusual project regarding set up as it was through 321 meters of private land that was not accessible. It was a job for a 6” pilot shoe and 3” assembly with soft soil present. The first 2m at entry side was sand and gravel followed by clay and soil. Exit side was mild dense soft soil and some big boulders that were visible when digging the exit pit.

Seeing as it was not possible to lay coil, the Large Field Beacon was utilized as a source of an electromagnetic field, making it possible to drill an HDD Crossing for electrical cables for wind energy.Tracking used: #ParaTrack2, Surface Coil and Large Field Beacon #LFB

Distance: 411.5m
Depth: 13m
Entry Angle: 15degree
Exit Angle: 14degree

Machelen Road Crossing

Canal crossing in Thailand

Pilot drilling & pipe pulling under the canals of Bangkok

Tracking used: ParaTrack2
Location: Bangkok, Thailand
Measured Distance: Pipe 1: 375 m Pipe 2: 325 m
Depths: 30 m & 28 m
Horizontal Curve: 12.2 degrees & 15.6 degrees
Entry Angle: 18 degree
Exit Angle: 18 degree
Ground: Clay
Pipeline: HDPE 180mm x 30 (bundle)
Technique: #Jetting – Bridge & #Canal #crossing
End use would be for Electrical cables

Job Description:
Drilling two pilot holes under the piling of a busy bridge of the bustling city of Bangkok with its deep canals without disrupting the daily goings on up above ground can pose quite a challenge.
To deal with the high #interference caused by communication cables present underground #steering was done with the #ParaTrack2. Two bundles of 30 HDPE pipes, measuring 180mm each were successfully pulled through under the existing underground utilities. Well done to the team involved and to Prime Horizontal #Australasia!
