Overcoming barriers

Abstract

Operating Company has deployed a number of offshore oil drilling platforms in China’s Bohai Bay oil field, achieving consistent cumulative oil production equivalent to one-fourth of China‘s crude oil consumption in 2015 – making it one of China‘s most important sources of energy. However, until recently, these platforms were unable to share power resources or exchange data, which caused considerable challenges for centralized management. In Bohai Bay, where China’s largest offshore oil and gas production field is located, an integrated broadband wireless solution from Siemens helped the operator Liaodong establish reliable data transmission between production platforms and overcome barriers in offshore network communication. Liaodong implemented a Distribution Management System (DMS) made up of multiple power sources. The DMS was put into trial operation in January 2013. However, bringing platform power plants established earlier, for example the Jin Zhou plants JZ 9-3, JZ 25-1, JZ 21-1, and JZ 20-2, into the monitoring range of the DMS without undersea optical cable communication posed a big challenge for the company – one that the extensive Siemens portfolio of wireless solutions helped to overcome.
