摘　　要：针对国外海洋升沉补偿装置价格昂贵的问题,开发了180 t浮式平台升沉补偿装置。该装置采用被动补偿和主动补偿联合控制模式,具有电反馈泵阀控制、并联增距半主动补偿、活塞运动等速设计以及跟随模拟信号测试等关键创新技术。对180 t浮式平台升沉补偿装置进行了静载和动载试验。试验结果表明,180 t浮式平台升沉补偿装置满足静载和动载工作要求,补偿精度达到80%以上。最后提出应进一步完成180 t浮式平台升沉补偿装置的工业性试验、加强安全阀国产化配套研究和继续开展补偿控制方式及补偿精度研究等3点建议。该装置的成功开发对海洋浮式钻井平台钻井系统的安全运行具有一定的参考作用。Due to the high cost issue of foreign marine heave compensator, a 180 t floating platform heave compensator device has been developed. The device uses joint control mode integrating passive and active compen-sation, with key innovations like electrical feedback for pump valve control, double stroke for semi-active compen-sation, uniform-velocity piston design and follow-up analog signal testing. Through test technique study, static and dynamic load tests for the heave compensator was determined. The results showed that the heave compensator has met the static and dynamic load requirements with the compensation accuracy of above 80%. Finally, three sugges-tions have been proposed that further industrial test should be conducted, study on safety valve domestication should be strengthened and compensation control pattern and compensation accuracy studies should be continued.
