China National Offshore Oil Corp. Ltd. (CNOOC) started work on the onshore power project for its Bozhong-Kenli oilfields in Bohai Bay.
The project includes four offshore electric power platforms and one onshore high-voltage substation. The designed power transmission capacity is 520 Mw, the largest onshore power project serving offshore oilfields in China, according to CNOOC. The project will supply electricity to 39 offshore production platforms in the Kenli oilfields, Bozhong 19-6 condensate gas fields, and Bozhong 28-34 oilfields. By 2025, the project is expected to support production of about 400,000 b/d.
Compared with self-generating electricity on the platforms, the onshore power project expects to achieve yearly savings of about 53,000 MMcf natural gas and 650,000 tonnes of standard coal. Nitrogen oxide emissions will be reduced by 14,700 tonnes, and carbon dioxide emissions will be reduced by 1 million tonnes, the company said.
