The BZ-28-1 Field was discovered in 1978 in the Bay of Bohai, offshore People's Republic of China, in an area prone to drifting ice in the winter season. This oilfield is being developed using a Floating Production, Storage and Offloading (FPSO) system incorporating innovative features. The new-built FPSO barge is moored to a fixed manifold platform via a disconnectable mooring yoke, so that the unit may sail away when ice ridges threaten its integrity. Although the concept of the mooring system is rather simple and proven by the successful operation of a similar unit offshore Nigeria, several novel design procedures and components have been developed and used to achieve the required performance for an optimal cost. The jacket of the manifold/mooring platform has already been installed in September 1987. The rotating head, the mooring yoke and the mooring legs have been delivered to China (PRC) where the FPSO barge construction is being completed. Final installation and hook-up of the barge is scheduled for August 1988. This unit will allow almost uninterrupted crude oil production and will be the first floating production system ever installed in waters where the probability of ice occurrence is quite significant. |
