This standard is based on the requirements of Document (98) Zhongyou Jijian Zi No. (33), and is edited by the Anti-seismic Office of China National Petroleum Corporation and Jiangsu Provincial Seismic Bureau. In the process of compiling this standard, the compilation team members carried out special research on the seismic isolation theory and seismic isolation materials of floating equipment, conducted comparative test research on floating equipment with and without seismic isolation devices, and compiled this standard using the latest scientific research results and engineering practice of seismic engineering. Finally, the Petroleum Engineering Construction Professional Standardization Committee and relevant departments reviewed and finalized the draft.
The main contents of this standard include: general principles, terms and symbols, determination of allowable vibration parameters of floating equipment, earthquake effects, seismic isolation design of floating equipment, inspection and installation of seismic isolation devices, etc. This standard adopts the secondary defense standard based on probability theory, and proposes two probability level design requirements for the seismic isolation coefficient and the maximum displacement control calculation that reflect the design principle of the floating equipment capsule. It is applicable to the seismic isolation design of floating equipment at different locations and the selection method of seismic isolation devices. This method is simple, practical, reasonable, highly operational and technically advanced.
The seismic isolation technology of floating equipment is a new technology in development, and there are still some problems to be solved through scientific research and practice in the future. Therefore, in the process of implementing this standard, please pay attention to summarizing experience and accumulating data. If you find any modification or supplement, please send your opinions to the Seismic Office of China National Petroleum Corporation, Liupukang, Xicheng District, Beijing (Postal Code 100724) for future revision. This standard is interpreted by the Jiangsu Provincial Earthquake Bureau.
