The offshore PAGA (Public Address and General Alarm) system is the important component of the platform's internal communication system. This system achieves the platform's full-area voice message, alarm signal coverage, and some other relevant functions by using the host controlling and speaker broadcasting. This paper analyses the configuration and function of the international mainstream platform's PAGA system in order to form a safe, reliable and economical offshore platform. The optimizing design scheme of this system provides an helpful reference for the relevant engineering and technical staff.%海洋平台PAGA（广播及通用报警）系统是平台内部通讯系统的重要组成部分，该系统通过主机控制及扬声器播放，实现平台全区域的语音及报警信号覆盖，以及其他相关功能。本文通过对目前国际主流平台PAGA系统配置及功能的分析，形成一种相对安全可靠、经济合理的海洋平台。该系统优化设计方案，为相关工程技术人员提供有益参考。
