SY/T 5053.2-2007 in English

本标准确立了控制系统的设计标准。该控制系统用于控制防喷器（BOP）以及在钻井中控制井口压力的相关阀件。本标准适用于子系统及部件上，不包括原材料选择和生产过程的控制，但可以作为采购时参考。虽然分流器不作为钻井控制装置，但是经常把它们作为防喷器控制系统的一部分来使用。因此，分流器控制系统也包含在本标准中。钻井控制设备的控制系统通常以加压液压液（动力液）的形式储存能量，控制防喷器组开和关。对防喷器或其他进控部件的每一个操作都称为一个控制功能。控制系统设备及电路一般随用途和环境的不同而变化。

Scope

This standard establishes design standards for control systems. The control system is used to control the blowout preventer (BOP) and related valves that control wellhead pressure during drilling. This standard applies to subsystems and components. It does not include raw material selection and production process control, but it can be used as a reference when purchasing. Shunt control systems are also covered by this standard. This standard describes the following control system categories: Above water blowout preventer bank control systems. Underwater blowout preventer group control system. Separate hydraulic control system for underwater blowout preventer assembly. Underwater blowout preventer assembly electric-hydraulic composite control system. Diverter control system. Auxiliary equipment control system and connection interface. Emergency Disengagement System (EDS). Backup system (optional). Parts designed for use in deep water and harsh environments (optional).
