Replies are rewarded; discussions are welcome. ------------------------------------------- The first phase of the Enping 15-1 oil field complex, owned by China National Offshore Oil Corporation, came online on December 7, 2022. The oil field complex features Asia’s largest offshore oil production platform and China’s first set of offshore carbon dioxide storage facilities. Zhou Xinhua, deputy general manager of China National Offshore Oil Corporation, said that the Enping 15-1 oil field complex is located in China’s Pearl River Delta Basin, with an average water depth of about 90 meters in that area. The oil field complex includes 4 new oil fields, with 48 production wells planned to come online. Once fully operational, the oil field complex will have a peak daily oil production of nearly 5,000 tons, thereby injecting new momentum into the economic and social development of the Guangdong-Hong Kong-Macao Greater Bay Area. The most important offshore facility in the Enping 15-1 oil field complex is the Enping 15-1 platform. With a total height of around 160 meters and a weight exceeding 30,000 tons, its single deck covers an area equivalent to that of 10 basketball courts. It is equipped with nearly 600 sets of machinery and systems, twice as many as those on conventional platforms. It can perform functions such as drilling, well maintenance, remote operation without human intervention, and carbon dioxide injection for storage. It is currently the offshore oil production platform in Asia with the largest deck area, the heaviest structure, the most equipment, and the most comprehensive set of functions.
The Enping 15-1 oil field complex is located in the Pearl River Delta Basin of China, about 200 kilometers southwest of Shenzhen, with an average water depth of around 90 meters in the area. The oil field complex includes 4 new oil fields, with 48 production wells planned to come online. Once fully operational, the oil field complex will have a peak daily oil production of nearly 5,000 tons, thereby injecting new momentum into the economic and social development of the Guangdong-Hong Kong-Macao Greater Bay Area. It is understood that the Enping 15-1 platform, which has been put into operation this time, is the most important offshore facility in the Enping 15-1 oil field complex. It was independently designed, constructed, installed, and operated by CNOOC. The total height of the platform is approximately 160 meters, and its total weight exceeds 30,000 tons. The area of a single deck is equivalent to that of 10 basketball courts. There are nearly 600 sets of equipment and systems installed on it, which is twice the number found on conventional platforms. It can perform various functions such as drilling, well maintenance, remote operation without human intervention, carbon dioxide injection for storage, self-generated power production and power networking, as well as integrated processing of oil, gas, and water. It is currently the offshore oil production platform in Asia with the largest deck area, the heaviest modular components, the most equipment, and the most comprehensive set of functions.
On CNOOC’s Enping 15-1 offshore drilling platform, the first domestically produced SXD-MAN16V32/40 type 7600KW crude oil generator set, manufactured by Shanchai Heavy Industry, a subsidiary of China Power under China State Shipbuilding Corporation, was successfully started up at sea and integrated into the platform’s power grid, thus taking on the role of supplying electricity for the platform’s operational and residential needs. As of September 17, the unit has been in operation for a week straight, with all performance parameters within normal ranges and stable operation!
Compared to land-based generator sets, high-power crude oil generators used at sea operate under harsh conditions and require higher technical standards; the marine environment demands that such generators have capabilities such as resistance to salt spray corrosion； The crude oil fuel used by the units has a complex and variable composition, with high levels of impurities such as heavy metals and waxes, which causes severe corrosion to the units ； Offshore platforms and FPSOs have limited space, requiring units with a small footprint and high degree of integration ； Special power plant operation modes require the units to have higher reliability, stability, and so on. For a long time, this field has been monopolized by foreign companies.
In 2010, Shaanxi Shide actively responded to the requirement for the localization of offshore engineering equipment. Through relentless efforts, it successfully secured contracts to supply two sets of SXD-MAN12V32/40 crude oil generator sets for the renovation project of the CNOOC Liuhua drilling platform, and delivered these units to the client in November 2011. It put an end to the long history of foreign monopolies over the crude oil generator sets used in the main power plants of China’s offshore drilling platforms, enabling domestic offshore drilling platforms to be equipped with domestic \"hearts.\" Shaanxi Chaiyi thus became the first Chinese company to enter the market for crude oil power plants in China’s offshore engineering sector. It has undertaken projects such as the comprehensive adjustment and development project for the Wenchang 13-2 oil field and the Enping 15-1 crude oil generator set project, and has developed a comprehensive team capable of handling design, processing, manufacturing, installation, commissioning, and maintenance of platform power modules. This transformation enabled Shanxi Chaiyi to evolve from a equipment supplier to a full-service project contractor.
