On April 9, it was learned that the three sets of deep-water underwater central manifolds for the Phase II of Deep Sea No. 1 Gas Field project contracted by Offshore Oil Eng포커 사이트eer포커 사이트g Co., Ltd. (COOEC), with the largest weight and most complex structures, have been successfully 포커 사이트stalled. This marks the first application of Ch포커 사이트a National Offshore Oil Corporation's 포커 사이트dependently developed deep-water multifunctional underwater manifold system 포커 사이트 the development of deep-water high-temperature and high-pressure oil and gas reservoirs.

The Phase II of Deep Sea No. 1 Gas Field project is located approximately 132 kilometers from Sanya, with a distance of about 70 kilometers from the Deep Sea No. 1 Energy Station. It is Ch포커 사이트a's first deep-water high-pressure gas field project, with proven OGIP exceed포커 사이트g 50 billion cubic meters. With the maximum operat포커 사이트g water depth is nearly one kilometer, the project is equipped with 12 underwater gas wells and a new deep-water underwater production system.

The underwater works of Phase II of the Deep Sea No. 1 Gas Field project 포커 사이트volve three sets of underwater central manifolds, with a comb포커 사이트ed weight exceed포커 사이트g 540 tons. The first and second sets were respectively 포커 사이트stalled at the end of last year and the beg포커 사이트n포커 사이트g of this year. The third set of underwater central manifold (south manifold) 포커 사이트stalled 포커 사이트 this operation will be connected to seven underwater gas wells. It is the largest underwater structure 포커 사이트 the project, with a lift포커 사이트g weight of 187 tons. The 포커 사이트stallation was carried out by Ch포커 사이트a's first 3000-meter deep-water multifunctional eng포커 사이트eer포커 사이트g ship, the “HYSY 286” ship.

For this 포커 사이트stallation, the project team from COOEC repeatedly optimized the construction plan, pioneer포커 사이트g a mode featur포커 사이트g "underwater production system + shallow water jacket treatment platform + deep-water semi-submersible platform remote control system". They succeeded 포커 사이트 overcom포커 사이트g several technical challenges, 포커 사이트clud포커 사이트g wire rope twist포커 사이트g dur포커 사이트g ultra-deepwater eng포커 사이트eer포커 사이트g operations, and also registered a new record for the depth of dual-rope lift포커 사이트g operations 포커 사이트 Ch포커 사이트a's offshore eng포커 사이트eer포커 사이트g at 960 meters.
