Shell Offshore Inc.'s Fairway field project offshore Alabama served as a proving ground for many developmental materials and techniques to cope with the field's hot, sour gas. This is the first of two articles on the project's first-ever field use of bimetallic corrosion-resistant alloy (CRA) pipe as well as the project's extensive use of corrosion inhibition. Among the new technologies employed by Shell Offshore to develop the Norphlet sour-gas trend were: Use of CRA-clad subsea flow lines; Development of a corrosion-inhibitor program for subsea pipeline transport of high-temperature, wet Norphlet sour gas; Cathodic protection of subsea pipelines at elevated temperature; Use of coiled tubing for subsea utility pipelines; Induction bending of high-strength, CRA-clad pipe; Welding of CRA-clad and weld overlaid materials; and Manufacture of bimetallic CRA pipe by coextrusion, thermal-hydraulic, and explosive forming processes.
