标准摘要
[中文适用范围]: 本文件提供了干预修井控制系统(IWOCS)设备的设计、制造和测试要求。防喷器(BOP)控制系统不在本推荐实践的范围内,且通常不与IWOCS连接。本文件确定了通常用于穿防喷器干预管柱系统(TBIRS)和开放水域干预管柱系统(OWIRS)的IWOCS设备;有关这些系统及其相关组件的更多详细信息,请参阅API 17G。本文档中描述的IWOCS设备也可用于其他系统类型。表1列出了通常由IWOCS控制的设备。有关两种系统类型的示例IWOCS框图,请参阅图1和图2。本文件中的一些要求是针对执行最终用户定义的安全功能的。定义安全功能是用户(即操作安全等级设备的有序事件序列)的责任。本文档定义了用于操作安全等级设备的“安全等级控制功能”。附录A提供了基于最终用户提供的安全功能确定安全等级控制功能的指导。 [外文原描述]: This document provides the requirements for the design, manufacture, and testing of intervention workover control system (IWOCS) equipment typically used in a thru-blowout preventer intervention riser system and an open-water intervention riser system. Some requirements in this document are specific to the execution of end user–defined safety functions. This document defines “safety class control functions” used to operate safety class devices. This document provides guidance on the determination of safety class control functions based on the end user–provided safety functions. Blowout prevention (BOP) control systems are outside the scope of this Recommended Practice and typically are not connected to the IWOCS.
