CNOOC Limited announced that Qinhuangdao Caofeidian onshore power project has commenced operation successfully. This onshore power project is located in the mid-western Bohai Bay, containing two parts, firstly the Qinhuangdao 32-6 and Caofeidian 11-1 oilfields onshore power project, and secondly the Qinhuangdao 32-6 facility capacity expansion project. The Qinhuangdao 32-6 oilfields are approximately 20 kilometres from the coast, with an average water depth of 19 meters. The Caofeidian 11-1 oilfields are approximately 30 kilometres from the coast, with an average water depth of 25 meters.The onshore power project has built with two onshore high voltage switching stations and two offshore electric power platforms, with a designed power transmission capacity of 200MW. It is positioned to provide electric power to Qinhuangdao 32-6 oilfields, Caofeidian 11-1 oilfields, and Caofeidian 6-4 oilfields. The Qinhuangdao 32-6 facility capacity expansion project has been constructed with two simple oil-water processing platforms both of which rely on the electricity supply of the onshore power project to scale up a holistic oil extraction and capacity expansion by taking advantage of the onshore power grid. It is estimated that the daily increase in oil production will reach the peak in 2023, about 8,100 barrels, an increase of nearly 20% over the current level.After the running the onshore power project, compared with self-generating electricity in the platform, the relevant oilfields are expected to save 85,900 tons of standard coal equivalents, reduce 4,000 tons of NOx emissions and 186,000 tons of CO2 emissions in peak years. It demonstrates remarkable energy saving and emission reduction effects, which marks a historic change in the power consumption mode of China’s offshore oilfield operations. It also signifies that the energy consumption structure of offshore oilfields has embarked on a fully-fledged implementation of low-carbon transformation.
