Williams NW Pipeline - Goldendale to Willard H.P. Anomaly Digs.
Perform 62 anomaly digs on an existing 26” pipeline in steep slope terrain typically greater than 30 degrees. In addition, replaced approximately 855 LF of existing 26” pipeline on 34-degree slope. Required winching of equipment up and down the steep slopes.
The original scope was to perform approximately 32 anomaly digs. Another 30 anomaly digs and pipe replacement added by Company after the project start. The objective was to repair the pipe to Williams's requirements so that line will stay in a safe operating condition.
Most of the digs were located in remote areas making communication extremely important. All crews were supplied with two-way communication equipment, hands-free headsets for operators on slopes, and satellite phones. All dig locations were measured out, and the appropriate number of winch cable slings were used.
Steep slope areas in loose, rocky soils required winches, cables, equipment with single bar grousers. Specialized crew carriers were utilized to move the crews up and down the slopes.
Project located in the environmentally sensitive and scenic Columbia River Gorge area. Worked with DNR throughout the project to mitigate work activities due to high fire risk. Altering our work schedule and providing additional fire safety equipment
Rock shields were placed up-slope of our crew's work area and one individual was placed as a lookout in case of falling debris.
