The Wellhead Barge a Versatile Solution for Mild Deepwater Conditions Event: The Wellhead Barge a Versatile Solution for Mild Deepwater Conditions Date: October 1999 Author: S. Hatton - 2H. S. Anres, P. Beligne - BOS. C. Gabillard - Sedco Forex The Wellhead Barge (WHB) is a wellhead platform solution developed by Bouygues Offshore (BOS) and its partners Sedco-Forex and 2H Engineering for the development of deepwater fields in mild conditions. This solution is based on a spread moored barge supporting the facilities required for drilling, completion and work over, partial production facilities and accommodating production risers with surface trees in a central well-bay. The WHB is linked by import / export lines to a main process centre. The WHB has been developed for West Africa and Indonesia. It takes full advantage of the mild wave conditions and the directionality of the sea states The paper will present the main features of a WHB designed to accommodate up to 24 surface trees and equipped for autonomous drilling. Technical topics will include general deck layout, well-bay area and drilling equipment definition, production riser preliminary design and installation principles, mooring system and drilling availability. Finally, the advantages of the solution will be presented together with the reasons why the WHB should be very effective in terms of CAPEX and OPEX.
