Electrically Heated Flowlines – A key Long Distance Delivery Management Tool
Deepwater production system development continues to manifest longer tie-back distances from remote areas to shallow-water host facilities, with demand and technology innovations prompting extension of industry capability.  For instance, multiphase production is enabling subsea development more than 120 kilometers from a production host/facility.  Effective field development planning and systems architecture also are driving tie-back lengths as long as 550 kilometers. Ultimately, long-distance delivery systems (LDDS) will produce directly from remote fields to onshore facilities, thus minimizing surface-piercing offshore structures and human exposure to remote areas far from land.   Long-term viability of LDDS however, is dependent on industry tackling certain technical and economic barriers. Electric Flowline (or Pipeline) Heating is likely to be a key technology element enabling Long Distance Delivery Management of Long Distance Delivery Systems.

The presentation will discuss basic concepts of EFH, types and limitations of EFH, and key system components and will briefly discuss the system challenges ahead.
