Data Buoy Support. The Coast Guard is responsible to provide for maintenance of NDBC buoys, and also establishes most new buoys and transports relieved buoys to maintenance facilities. This service is almost always conducted with NDBC technicians present. Requirements of this activity include transportation of technicians to buoys and the ability to provide maintenance and industrial support. Assets also must establish real time communications links with NDBC’s data network to validate data being transmitted by the buoy. Finally transportation of replacement buoys to and from station is required.
