On September 23, 2021, China’s first offshore pilot oilfield shore power project, the Qinhuangdao-Caofeidian Oil field Group shore power project, belonging to China National Offshore Oil Corporation (CNOOC) in the Bohai Sea region, was successfully put into operation.
Qinhuangdao-Caofeidian oilfield shore power project includes an offshore 220 kV offshore Haifeng power platform, 220 kV onshore Haidiao switching station, 220 kV offshore Haiyu power platform, and 220 kV Haishun switching station. The successful operation of the project marks the completion of offshore and onshore parts of the Bohai oilfield shore power project as scheduled.
Shore power project
Traditional offshore oil fields mainly use natural gas and crude oil from oil fields as fuel for power generation
Traditional offshore oil fields mainly use natural gas and crude oil from oil fields as fuel for power generation, which not only has low efficiency and high energy consumption but also has much lower stability than large power grids.
After the shore power project is put into operation, it can reduce the crude oil consumption by 175,000 m3, the natural gas consumption by 2.38 billion m3, and the carbon dioxide emission by 1.75 million tons compared with the annual power generation.
The successful commissioning of the project will completely change the 'self-generating mode' of the offshore oil fields in the past. It is of great strategic significance for China to promote the adjustment of the national energy structure and achieve the goal of energy saving and emission reduction, and promote the healthy development of the offshore oil industry.
Advanced nature of the whole solution
As the supplier of complete secondary system equipment for the shore power project, NR has provided an entire system of core equipment such as an integrated automation system, protection equipment, safety and stability control system, and inrush current suppressor for the four 220 kV substations of the project.
In order to ensure the adaptability and advanced nature of the whole solution, NR has made an in-depth analysis of the unique characteristics of the shore power project's safety, stability, and operation & maintenance. As all systems of the offshore electric power platform are in the special marine environment of high humidity and salt, the entire equipment provided by NR has successfully passed and fully met the operational standards in the marine environment.
Reliable shore power supply solutions
From equipment manufacturing to production commissioning, and then to project support construction, NR assisted in the smooth implementation of the Qinhuangdao-Caofeidian shore power project with advanced technology, excellent products, and professional services, providing strong support for the power network construction of CNOOC offshore oil field group.
NR will continue to provide safe and reliable shore power supply solutions with digital, unmanned and intelligent applications for CNOOC offshore oilfields in the future.
