In recent years, offshore oil and gas exploration and development efforts have continued to increase. In order to solve the "stuck neck" technology of offshore oil equipment testing, recently, the Municipal Industrial Product Inspection and Metrological Verification Center and the Qilong Company, the Beijing Research Center of CNOOC (China) Co., Ltd., China University of Petroleum (Beijing) joint research and construction, my country's largest and deepest offshore oil underwater equipment testing and test center has been officially put into operation recently.

The test center can carry out a series of inspection and test items such as Christmas tree, high and low pressure wellhead, overall air tightness test of Christmas tree, tubing hanger, casing hanger, sealing assembly, Christmas tree protection device, and submarine pipeline corrosion. The test center has a maximum detection air pressure of 24000 psi and a detection water pressure of 36000 psi. The tank specifications and equipment meet the requirements of water pressure and air pressure testing for products in the petroleum industry and non-oil industry.

In recent years, the Municipal Industrial Product Inspection and Metrological Verification Center has been based on the needs of Dongying’s high-quality social and economic development, innovated working methods and methods, made every effort to improve product inspection and testing capabilities, and actively served government market quality supervision, enterprise transformation and upgrading, and people’s livelihood safety. To build a leading domestic and internationally advanced professional scientific research public testing service platform. The official operation of the Offshore Oil Underwater Equipment Testing and Testing Center marks a leap-forward improvement in the inspection capabilities of the Dongying City Industrial Product Inspection and Metrology Verification Center in the field of offshore oil equipment.
