en.Wedoany.com Reported - The offshore installation of the Bozhong 26-6 Oilfield Phase II project module, operated by CNOOC, has been completed. This oilfield is the world's largest metamorphic buried hill oilfield. The main hook of the "Blue Whale 7500" crane vessel was slowly lowered, and the WHPD module was precisely positioned, laying the foundation for the project's scheduled production.
Located in the central Bohai Sea, the Bozhong 26-6 Oilfield commenced its Phase I development project in 2025. This oilfield carries the mission of energy security, green transition, and scientific research. It is a key carbon capture, utilization, and storage (CCUS) demonstration project planned by CNOOC in the Bohai Oilfield and a supporting project for studying the geotechnical properties and bearing capacity laws of the Bohai region.
The Phase II project adopts a development strategy of "overall planning, phased implementation, and integrated advancement," aiming to significantly boost China's domestic oil and gas production and further strengthen the clean energy supply and livelihood security capabilities of the Beijing-Tianjin-Hebei region and the Bohai Rim area.
The project fully applies the serialized results of jacket structures and standardized construction technologies. Through three major innovations—modular design, prefabricated production, and digital assembly—it promotes the standardized production of multiple facilities, improving construction efficiency and material utilization. During offshore operations, the project team addressed challenges such as dense structures around subsea pipelines and limited working space by conducting early subsea pipeline re-inspections and high-precision positioning. They performed pre-drills based on pipeline routes and burial depths to optimize lifting and anchoring plans. Simultaneously, real-time monitoring of lifting postures and vessel status was carried out, with dynamic adjustments to the operational window based on sea conditions. This ultimately achieved the precise one-time lifting and positioning of all modules, with positioning accuracy reaching the millimeter level.
