Ortega River Crossing - Jacksonville, FL
This 48-inch diameter steel pipeline crossing was a replacement for a failed HDPE treated sewage main. Drilling was through clays and sand. The drilling profile included a compound curve (both horizontal and vertical radii). The pipeline was fabricated in two (2) strings due to restricted site availability. The tie-in weld and coating completions were made in 12 hours during which time the pullback operation was suspended. Once the tie-in was completed, the pullback was recommenced - pull loads did not exceed calculated predictions.
