The 220-kilovolt inland transformer substation of China National Offshore Oil Corporation (CNOOC)'s Bozhong-Kenli oilfield cluster shore power application project, located in East China's Shandong Province, has been put into service.
The Bozhong-Kenli oilfield cluster shore power application project is a part of CNOOC's Bohai shore power application program that also includes sub-projects in North China's Hebei Province and Northeast China's Liaoning Province. The Shandong section has the largest oilfield coverage, the greatest engineering and the highest power consumption of its kind in China.
The project includes construction of one 220-kV inland substation which will connect with three 220-kV offshore electric power platforms via five 240-kilometer 220-kV high-voltage alternating current submarine cables. It will provide green shore power to oil production and development platforms in the oilfield cluster.
The newly-operable transformer substation is the "central processing unit" of the Shandong project responsible for information collection and processing, remote surveillance, error diagnosis, and remote control, maintenance and scheduling of the offshore electric power platforms of the Bozhong 34-1, Bozhong 35-2, Bozhong 19-6 and Kenli 10-1 oilfields. It will play a key role in guaranteeing safe power use of 26 offshore production platforms.
Once operational, the Shandong shore power project is expected to reduce natural gas consumption by 1.5 billion cubic meters during peak years and cut down on use of nearly 650,000 metric tons of coal annually, eliminating one million tons of carbon dioxide. The project will be of great significance in promoting green development of offshore oilfields and contributing to realizing China's "dual carbon" goal of peaking carbon dioxide emissions by 2030 and achieving carbon neutrality by 2060.
To date, offshore installation of the Bozhong 34-1 and Bozhong 35-2 shore power modules has been completed. Next, the developer will install other offshore modules and carry out land-sea joint adjustments.
