PIPELINE SPANNING-1 ROUTE SELECTION KEY FIRST STEP IN AVOIDING OCEAN FLOOR SPANS
Marvin M. Beckmann, James R. Hale, Craig W. Lamison Brown & Root Inc. Houston Pipeline spanning is becoming a greater concern in the U.S. Gulf of Mexico as field development moves into deeper waters. Two factors combine to create the problem. First, seafloor topography becomes more irregular as pipelines move from the relatively smooth continental shelf to the steeper, irregular bathymetry of the continental slope. Second, pipeline installation tension increases in deeper water.
