The laying of the main submarine cables of the power platform at the Caofeidian 11-1 oilfield in China's Bohai Sea was completed on May 28. The platform is about to be equipped with an offshore power transmission and distribution function.
The newly-laid cables included two 220-kilovolt and one 110kV submarine cables, used respectively to connect two offshore power platforms with the land switching station, and the Qinhuangdao 32-6 with the Caofeidian oilfield cluster. The two lines will form a double circuit that will guarantee a reliable power supply of the offshore production platforms.
The laying of a 220kV submarine cable linking Laoting and the Qinhuangdao 32-6 power platform and a 110kV cable between the Qinhuangdao 32-6 platform and Caofeidian oilfield cluster was completed on May 12 and 19.
Laoting and Caofeidian are administered by Tangshan, which neighbors Qinhuangdao. All these regions lie within North China's Hebei Province.
There are now nearly 120 workers busy debugging the power platforms at the oilfield cluster.
The project was contracted by China National Offshore Oil Corporation.
