Offshore Oil & Gas Development Solution
After many decades of development and accumulation, COOEC has formed a complete set of mature technology, equipment and capability system for offshore oil and gas field development, design, construction, installation and maintenance, and is able to provide customers with turnkey and diversified projects more efficiently. COOEC has vigorously developed strategic emerging industries, actively promoted the construction and upgrade of traditional industries to deep water and underwater high-end marine equipment, achieved a leap in deep water oil and gas field engineering capacity from 300m to 1,500m, and made a series of major technological breakthroughs in deep water, subsurface and other fields. COOEC has expanded its traditional offshore oil and gas engineering business to include onshore LNG engineering, offshore wind power and other clean energy fields, which has contributed to the continuous improvement in its comprehensive competitiveness.
At present, COOEC is accelerating the transformation to an international engineering general contractor, speeding up the transformation of business structure to low carbonization and full industrialization, and driving the transformation of production mode to standardization and digitalization. By enhancing the value creation ability in all aspects, COOEC provide customers with “package” solutions for marine energy engineering.
Onshore Oil & Gas Development Solution
COOEC is accelerating green upgrading efforts, achieving a leap from “offshore” to “onshore”, cultivating and forming comprehensive onshore oil and gas terminal businesses such as LNG terminals, LNG storage tanks, natural gas liquefaction plants, etc.
As an EPC contractor, COOEC has undertaken more than 10 key onshore oil and gas comprehensive terminal engineering projects. There are currently 41 LNG storage tanks in operation and under construction, with storage capacity ranging from 30,000 cubic meters to the world’s largest capacity of 270,000 cubic meters. The company has contracted LNG engineering projects worth over 30 billion yuan, making it a top-tier LNG engineering company in China, among which, the Tangshan LNG Terminal Project is currently the largest LNG Terminal project proposed in China, with an annual LNG processing capacity of 20 million tons upon completion. Zhuhai LNG Phase II and Zhejiang LNG Phase III projects plan to build a total of 11 LNG storage tanks with a capacity of 270,000 cubic meters each. The storage tank core technology is independently designed by CNOOC, marking a comprehensive breakthrough in the design and construction technology of super-large volume LNG storage tanks in China, reaching the global leading level.
Through scientific and technological research and development as well as engineering project experiences, COOEC has developed core competencies such as the design capability of LNG terminal storage tanks, EPC contracting capability for LNG terminal storage tanks, EPC contracting capability for natural gas liquefaction plants, EPC contracting capability for LNG cryogenic insulation projects, and EPC contracting capability for crude oil storage tanks and natural gas processing plants.
