Liuhua 11-1 development -- Design and fabrication considerations for the FPS Nanhai Tiao Zhan
The Nanhai Tiao Zhan is a major component of the Liuhua 11-1 Development System. It is a modified drilling semi-submersible specially converted to maintain station in a severe typhoon environment, drill and complete horizontal subsea wells, supply power for downhole electrical submersible pumps, and support installation and maintenance of the unique Liuhua 11-1 subsea production system. Final design and conversion of the Nanhai Tiao Zhan was accomplished in approximately two years. In the first year, a major engineering effort produced plans and specifications for converting a Sedco 700 series mobile offshore drilling unit into the floating production system Nanhai Tiao Zhan. The second year of the project entailed procurement and construction activities associated with the unit`s conversion and refurbishment. The project was accomplished on schedule within its original budget.
