The land-based construction of the jacket structures for China’s largest offshore shore power project has been completed. On August 4, it was reported by CNOOC Tianjin Branch that the three jacket structures for the shore power application project in the Bozhong-Kenli oil field complex were successfully loaded onto the \"Offshore Oil 225\" ship at CNOOC Engineering’s Qingdao facility, marking the completion of the land-based construction of the jacket structures for this country’s largest offshore shore power project. According to Zhang Xiao, manager of the Engineering Management Department at CNOOC Tianjin Branch, the shore power application project for the Bozhong-Kenli oil field complex is a key initiative by CNOOC aimed at promoting large-scale replacement of electricity with other energy sources and developing smart oil fields. This project has enabled the use of domestic-made submarine cables and other essential electrical equipment, thereby reducing reliance on imported equipment from abroad. It helps China keep control over its own equipment manufacturing capabilities. At the same time, it plays an important role in facilitating the green development of offshore oil and gas fields in China and contributing to the achievement of the country’s \"dual carbon\" goals. “The shore power application project for the Bozhong-Kenli oil field complex includes 4 jacket structures and 4 modules, with a total weight of 21,497 tons. Construction of the jacket began on February 21, 2022. Facing challenges such as a tight schedule and the impact of the pandemic, the project team worked closely together, formulated scientific construction plans, concentrated available resources, and continuously improved construction efficiency, managing to complete the construction of all 3 jackets in just 4 months. ”Wang Peng, the construction manager of the general contracting project for the shore power application in the Bozhong-Kenli oil field complex carried out by CNOOC Engineering, explained.
During the loading process, the project optimized the loading plan, reducing the need to use one 12,000-ton self-propelled barge and thus saving significant costs associated with renting ships. Multiple technical discussions were held prior to construction, along with scenario analyses, to identify major risks and prepare contingency plans in advance, ensuring strict adherence to safety standards. As a result, a record was set by completing the loading of 3 jacket structures within 24 hours. It is understood that the shore power project primarily involves transmitting high-voltage electricity from land to the sea; through specially constructed shore power platforms, this electricity is transformed and delivered, providing green shore power to various production and oil extraction platforms in the oil field complex. This approach replaces the traditional reliance of offshore platforms on on-board generators for power generation, thereby enabling an innovation in the power supply system for these platforms. This project not only helps to reduce the electricity costs of new oil fields in the surrounding area, thereby enabling cost savings in oil field development, but the newly laid submarine cables also serve both for power transmission and communication purposes. They create a communication \"highway\" between offshore oil fields and land, laying a solid foundation for the development of intelligent and digital oil fields in the Bohai Sea region.
