From July 2001 to October 2002 CONAM expended over 130,000 project man-hours for installation of both onshore and offshore pipelines from the existing onshore Trading Bay Oil Production Facilities to Forest Oil's Osprey Platform, 2 miles offshore from West Foreland in Cook Inlet . Work scope involved laying of several offshore pipelines and a power and communications cable on the seabed of Cook Inlet from the shore to the platform legs. Significant effort was required for the installation of 4 each, 1,700 LF casing through a 200 ft high shoreline bluff using horizontal directional drilling. The casings "day-lighted" in 10 ft of water offshore and were used as guides to pull the prefabricated lengths of line pipe and cable from the top of the bluff to the platform. The two 8" and one 6" pipelines were pulled by a heavy offshore barge, anchored a three different locations. The final pull into the platform legs was performed by a specially fabricated hydraulic chain jack with barge assist.
The onshore portion consisted of extending the three new offshore heavy wall pipelines to a new facility pad, Kustatan Pad located approximately 1.7 miles inland. Two pipelines - 6" and 8" - with a combined length of 12.8 miles from the Kustatan Pad to the final tie-ins to the Trading Bay Facility.
