The broadcast system of Nanhai No.7 drilling platform has been upgraded.

Some alarm types of NH7 universal alarm system are incomplete, and the coverage of universal alarm four-color lights is small, and it does not meet the alarm requirements of the latest CNOOC and corresponding specifications. Therefore, it is necessary to upgrade the broadcasting and universal alarm system, add corresponding alarm tones and four-color alarm lights. The reformed universal alarm system matches other input and output devices of the existing system, and meets the latest alarm signal requirements of SY T 6633-2019 Emergency Alarm Signal Guide for Offshore Oil Facilities.
