IMPERIAL OIL (IOL) PROJECT
SUBLATUS INC.PILE CUTTING PROPOSAL
A field-ready plan using Innovative Well Abandonment’s ultra-high-pressure waterjet cutting systems with dual pumping systems.
Compliant
01 — Project Area
IMPERIAL OIL COLD LAKE
Sublatus — Imperial Oil project northwest of Cold Lake, Alberta
NORTHWEST OF COLD LAKE
The scope covers approximately 4 km of above-ground pipeline supported by 8-inch and 10-inch piles spaced approximately 10 metres apart. Sublatus removes the pipelines; Innovative Well Abandonment cuts the piles 3 metres below surface.
Applications
01
Pipelines
02
Gas plants and oil sands sites
03
Production facilities
04
Tank farms
05
Well sites
02 — Technology
Cutting Technology & Execution
Ultra-high-pressure waterjet cutting, and the sequence the crews follow on each pile.
Ultra-High-Pressure Cutting
Dual pumping systems drive ultra-high-pressure waterjet cutting through pile walls without heat or sparks.
Minimal Ground Disturbance
Cuts are made from inside the pile, with minimal to no disturbance to the surrounding ground.
3 m Specified Depth
Piles on this project will be cut 3 metres below surface. The system can reach 10 metres or more.
External Cutting Tools
External cutting tools are available as an additional capability where internal access is limited.
Execution Sequence
- 01
Sublatus shears off the pipelines and I-beams.
- 02
IWA will cut piles to approximately 1 ft above surface, then water jet cut at 3 m below surface.
- 03
Internal debris is checked and cleared, with steaming if required.
- 04
Sublatus pulls the piles with a tracked excavator.
- 05
IWA backfills the holes with a backhoe using client-supplied material.

04 — Assumptions
Assumptions & Conditions
The basis of estimate for this proposal, including access, schedule and operating conditions.
Backfill Material
The client will supply sand or other suitable backfill material. IWA will backfill every hole using a Case 590 backhoe.
Pile Removal
Sublatus will provide the tracked excavator and pull each pile once IWA completes the cut.
Pipeline Removal
Sublatus will shear off and remove the above-ground pipeline and I-beams before IWA begins pile trimming.
Pile Interiors
Steaming may be required to clear debris from pile interiors before the internal cut can be completed.
Cut Depth
Piles will be cut 3 metres below surface with a 360-degree UHP waterjet cut.
Pricing Option
The client will select either per-pile pricing (Option A) or the day rate (Option B) before mobilization.
Accommodation
Subsistence is charged at $275 per person per day, or $0 where camp accommodation is provided.
Site Access and Safety
The client will provide site access along the right-of-way, site orientation, and any required gas-detection and communication devices.
