Prep work for export pipelines on Scrab/Saffron development: Stolt Offshore S.A., charged with the task.
Prior to the work beginning, a cofferdam was constructed that reached just over 1,300 feet out into the Mediterranean. As noted by BP Egypt, it was critical to the success of the project that two export pipelines be successfully winched onto the beach at Idku last year so that crews could complete the pipeline system this year in time to meet the planned first gas date in early 2003.
Working under a subcontract to Stolt Offshore S.A., Egyptian offshore contractor Petroleum Marine Services was charged with handling the shore approach work,
A pipelay barge, operated by Petroleum Marine Services was anchored about a half mile offshore and a steel cable was passed along the axis of the cofferdam to the winch. Offshore the cable was connected to a pulling head. As crews aboard the barge welded up the 40-foot joints of 24-inch concrete-coated pipe. The winch was used to pull the pipe joints off the barge and toward the beach.
The process continued until the pullhead emerged out of the cofferdam and was pulled on to the beach. The entire operation, which began in September 2001, took about eight weeks. Although the beach pull only involved only a short section of the pipe. it was a critical operation that was completed successfully, Later this year. Stolt Offshore will return with a large my barge and pick the pipes up off the seabed and link them to the subsea production system.
