Amec Foster Wheeler Solves Pipe Stress Challenges with CAESAR II

Amec Foster Wheeler provided engineering analysis for a fine tailings treatment project in the Athabasca Oil Sands region in Alberta, Canada. The KFTT project handles 100,000 bpd capturing the fines from flotation tailings through thickener. The project equipment included the flotation thickener, the recovered bitumen tank, the overflow water tank and gravity distributor, slurry pumps, the gland water pump, and bitumen sump pump.

The 42” diameter pipe for overflow water would operate at a temperature of 95 degrees Celsius and a pressure of 2,500 KPaG. The pipe runs 1,000 meters in a common trench with four other pipelines. Normal engineering practice calls for carbon steel (CS) for deep buried piping, but for overflow water service, the service life of CS is only five to eight years due to corrosion. It would be difficult to replace this individual pipe in a common trench with other pipes, entailing huge costs for soil excavation and backfill. To achieve a lifetime operation, fiberglass reinforced plastic (FRP) piping material would be needed.

Amec Foster Wheeler received the CAESAR II Runner-Up Drivers of Success Award for its use of the software. The annual Drivers of Success competition recognizes innovative applications of Hexagon products, impressive project results, and significant benefits from collaboration among disciplines and the integration of the products.
