Overall Upgrading and Reconstruction Project of Equipment and Facilities in Chengbei Oilfield

It is the first large-scale offshore platform upgrading and reconstruction project in China, with the operation difficulty and workload ranking first in China: hundred sets of installation equipment dismantled, 350,000 m cable newly-laid, 11,000 m pipeline reconstructed, and three 2,000 m3 large crude oil tanks dismantled, equivalent to the workload of constructing a new 10,000-ton central processing platform. Chengbei Oilfield, as the first offshore oilfield designed in line with international standards in China, it not only welcomes its "second spring” through this upgrading and reconstruction, but also provides valuable experiences for large-scale platform upgrading and reconstruction projects of CNOOC in future.
