  • Method and system for guaranteeing safety of offshore oil well control equipment
    Patent number: 11346200
    Abstract: The present disclosure belongs to the field of marine engineering, and in particular relates to a method and system for guaranteeing the safety of offshore oil well control equipment. The method comprises: identifying the state of a main structure of the offshore oil well control equipment, identifying the state of a hydraulic control unit of offshore oil well control equipment, identifying the state of an electronic control unit of offshore oil well control equipment, predicting the state of the offshore oil well control equipment and making a real-time decision based on existing information; and the system for guaranteeing the safety of the offshore oil well control equipment comprises a state identification subsystem of a main structure, a state identification subsystem of the hydraulic control unit, a state identification subsystem of the electronic control unit and a state prediction and real-time decision subsystem.
    Type: Grant

    Date of Patent: May 31, 2022
    Assignee: China University of Petroleum (East China)
    Inventors: Baoping Cai, Yonghong Liu, Chao Yang, Xiangdi Kong, Yi Zhao, Hongqi Xu, Xincheng Li, Yandong Chen, Renjie Ji, Zengkai Liu, Libing Liu, Rikui Zhang, Yuqian Yang, Shitang Liu, Xin Wei
  • Method for assessing safety integrity level of offshore oil well control equipment
    Patent number: 11243509
    Abstract: The present disclosure belongs to the field of offshore oil, and in particular relates to a method for assessing the safety integrity level of offshore oil well control equipment. The method for assessing the safety integrity level of the offshore oil well control equipment comprises three major steps: creating a safety instrumented function evaluation module and dividing the related devices for performing the safety instrumented functions into a sensor subsystem; a controller subsystem and an actuator subsystem, establishing a dynamic Bayesian network model for respective subsystems for calculation; and integrating, analyzing and optimizing the safety integrity data of the subsystems.
