This maritime equipment belongs to the radar communication category, providing essential navigation support. The L-8 / S-707 / CW / CBM-G22 model, manufactured by Hyundai Welding Co., Ltd. (Pohang), adheres to IMO SOLAS regulations and operates on both X-Band and S-Band frequencies. Its electromagnetic radar system ensures reliable performance for vessel navigation and safety. The radar is DNV-approved and is designed to withstand marine environments, though it may encounter common failures such as end-of-life magnetron issues after 5,000 to 8,000 hours of operation, bearing damage in the antenna rotation motor after 30,000 hours, and backlight failure in the display. It is crucial to maintain spare parts, particularly a spare magnetron, on board as lead times for replacement parts can take 1 to 3 weeks. Regular maintenance includes replacing the magnetron at the specified intervals, annual lubrication of the antenna bearing, weekly performance monitoring tests, and an annual inspection to ensure optimal operation.
What our service work and the manufacturer documentation say about keeping this model running.
Magnetron replacement every 5,000-8,000 hours. Antenna bearing lubrication annually. Weekly performance monitor test (IMO requirement). Annual inspection.
Hyundai Welding Co., Ltd. (Pohang): Keep a spare magnetron on board (on magnetron models). Lead time: 1-3 weeks.
