Key technology for non-slide construction of Wenchang 9-7 jacket center truss
This study aimed to ensure the timely productionof the Wenchang 9-7 oilfield development project.Compared with the traditional slide construction technology,the center truss non-slide construction technology was creatively adopted to the Wenchang 9-7 jacket.It took only5 months to complete the final assembly of the 16,000-ton pipeline rack,which greatly shortenedthe construction and final assembly cycle of the jacket and effectively ensured the timely completion and shipment of the Wenchang 9-7 jacket to the sea.Site layout and construction,shipment schemes for central truss,and risk control measures were studied to ensure the feasibility of non-slide construction schemes.The technology can greatly reducethe slide resources used by jacket construction.Unlike the traditional slide construction technology,the non-slide one is shorter in the construction cycle to expedite the process,lower in cost to reduce the investment,and higher in precision to guarantee quality.
