Ships' crew, engineers, and operators rely on reliable radar systems to ensure safe navigation, particularly in challenging weather or low visibility conditions. Hyundai Welding Co., Ltd. (Pohang) offers the M-12K / S-717, an X-Band / S-Band radar system compliant with IMO SOLAS regulations. This electromagnetic radar has been granted approval by DNV. While the M-12K / S-717 is designed for dependable performance, certain common issues may arise over time. These include magnetron end-of-life after 5,000-8,000 operating hours (applicable to magnetron models), antenna rotation motor bearing damage exceeding 30,000 hours, display backlight failure, heading marker orientation drift, and waveguide moisture ingress due to pressure system disruption. Hyundai Welding Co., Ltd. (Pohang) recommends keeping a spare magnetron on board (for magnetron models), with a lead time of 1-3 weeks. Routine maintenance is essential, including magnetron replacement every 5,000-8,000 hours, annual antenna bearing lubrication, weekly performance monitor tests (as per IMO requirement), and an annual comprehensive inspection.
