The client approached Crondall Energy to investigate an ongoing issue with a 16-inch gas export pipeline, installed in 2007, that transports gas over 150 km from an FPSO to a platform in shallow water. The pipeline is located in West Africa in approximately 1100-1300m water depth.

The North Sea field production flowlines operate at high temperature and are susceptible to lateral buckling and walking. Members of the Crondall Energy team had previous experience providing operational support and identify any potential integrity issues. In the past the field had experienced pipeline slugging issues which were resolved by the work performed by Crondall Energy engineers. The operational support by our engineers continues which resulted in the identification of pipeline walking issues.
