The Wenchang 19-1 Phase II development project involves the construction of an 8-leg, 12-skirt pile drilling and production platform equipped with a 7,000-meter modular drilling rig. For the first time in the western South China Sea oilfield, six new domestically developed technologies are being used, including turbine power generation, waste heat recovery, siphon-type associated gas recovery, plasma torch, lithium bromide air conditioning, and edge data centers. The oil and water treatment system adopts a "large throughput, short process" high-efficiency separation process, with a total treatment capacity of 48,000 cubic meters per day, significantly boosting the production capacity of CNOOC's Zhanjiang branch.
The Wenchang 9-7 Oilfield development project features a deepwater jacket platform with an 8-leg, 12-skirt pile structure, accommodating 35 well slots. The total height is approximately 141 meters, and the total weight exceeds 16,000 tons, making it the largest and heaviest jacket platform in the western South China Sea oilfields. Construction on the jacket began in October last year.
These two projects are located at China’s leading offshore engineering manufacturing sites. Through an annual framework agreement, Steelda has provided optimized solutions for clients, combining futures-based rolling with inventory stocking to reduce procurement costs and address scattered material requirements, while meeting tight project deadlines. In supporting China's energy journey into the deep sea, Steelda is fulfilling the historical mission entrusted to us by the times.
