We owe a big thanks to Shane McWhirk from Peak Oilfield Service and the APE Parts Department for getting us this story and pictures from Prudhoe Bay, Alaska. The APE 200-6 was used successfully in cold temperatures (-10 F thru -35 F) for driving the piles for Peak Oilfield Service’s job. The Hydraulic tank was insulated and heated with heat pads that were supplied electricity from a generator. Permafrost layers are between 6 to 15 feet making driving some of the toughest a vibratory driver/extractor could encounter. A 30 year crane operator from Florida that has put thousands of piles in the ground compares the permafrost layers to granite.
