CNOOC laid offshore oil and natural gas pipelines for offshore drilling platforms. The engineering included laying the pipelines from offshore drilling platform to landing zone, laying the pipelines between two platforms, and installing vertical pipes for platforms. Aiming at the characteristics in the diving project management, this paper analyzes and evaluates the difficulties and risks of underwater work, puts forward the corresponding safety managements. These measures ensure the underwater operations safely and smoothly. The engineering lasts 195 days, uses 160 diving equipments, and dives 282 person-times. The total diving time is 17900 minutes, and the maximum diving depth is 70 meters. © (2014) Trans Tech Publications, Switzerland. Source

This thesis introduces design principle, methods and composition of a new test device for carbon dioxide absorbents as energy materials based on pressure sensor and temperature sensor. The error of the test device is analyzed. The results show that the error of the device is acceptable after correcting, the error can be ignored. The test results are reliable. © (2012) Trans Tech Publications, Switzerland. Source
