Recently, the Hydraulic Power Recovery Turbine (HPRT) device, developed under the leadership of CNOOC (China) Limited Beijing Research Center, has successfully completed the whole machine test and was delivered. It will be deployed in the Bozhong 19-6 gas field, utilizing the residual pressure of the seawater system on offshore platforms to generate power for the platform.
At present, the seawater pump of offshore platform is mainly used for equipment cooling, and the used seawater contains a large amount of potential energy and kinetic energy in the process of sea discharge. The HPRT device introduces seawater from the ocean into the hydroturbine, converting the potential and kinetic energy into mechanical energy, which is then converted into electrical energy by a generator to power the platform’s production.
This device is China’s offshore HPRT device with independent intellectual property rights. The device has an installed power of 132 kilowatts, making its energy recovery efficiency over 80%. After it is put into use, it is expected to save 1.064 million kilowatt-hours of electricity and reduce more than 1,000 tons of carbon emissions annually.
The successful delivery of this device fills the gap in the domestic waste energy recovery HPRT series products, and marks a breakthrough in the HPRT device from source design to on-site application.
