China's first self-developed deepsea underwater Christmas tree has been put into operation, a key breakthrough in the country's design, manufacturing and application capacities in the field.
The underwater Christmas tree is a core part of the offshore underwater oil and gas production system.

The newly-operable facility weighs 55 metric tons and consists of over 2,500 components. It features safe and isolated oil storage layers and can ensure safe operation under the oil wells. It also effectively lowers the costs of relevant projects.

Making use of the facility, China National Offshore Oil Corporation employees have carried out nearly 50 missions including excavation of a natural gas development well.
Its operation is expected to promote application of advanced domestically-made equipment in marine oil and gas resource exploitation and development, improve the self-sufficiency rate of energy and guarantee national energy security.
