摘要
介绍了海上固定平台PA／GA系统的参考规范、设计原则及方法，分析并阐述了该系统功能、技术要求，以及关键参数选取和声压计算，力求为平台提供稳定、可靠、高质、清晰的语音播报服务，并满足生产安全和生活需求。针对特种船有主竖区结构并结合铺管船项目N448阐述了PA／GA系统在特种船中的应用。
The reference rule, design principle and method of the public address （PA） / general alarm （ GA ） system on offshore fixed platform are introduced. The functions, technical specification, key parameter＇s selection and sound tension calculation for the system are analyzed for an actual offshore fixed platform projects. The system can supply stable, reliable, top-quality and clear sound broadcast service and meet produce safety and living requirement. Taking the pipelaying heavy lift offshore N448 project as example, the application of PA/GA system in the main vertical zone of special purpose ship is elaborated.
