The SC-71Ni4/C1 radar system operates on electromagnetic waves in the X-Band and S-Band frequencies, adhering to International Maritime Organization (IMO) and Safety of Life at Sea (SOLAS) regulations. Designed and manufactured by Hyundai Welding Co., Ltd. in Pohang, this radar system is approved by DNV. The system’s magnetron, a critical component, typically needs replacement after 5,000 to 8,000 hours of operation, and it is advisable to have a spare magnetron on board to ensure uninterrupted radar functionality. Additionally, the antenna rotation motor can suffer from bearing damage after 30,000 hours of use, and the display backlight may fail over time. Regular maintenance includes annual inspection, annual bearing lubrication for the antenna, and a weekly performance monitor test as per IMO requirements. It is also important to monitor the waveguide for moisture intrusion, which can occur if the pressure seal is compromised.
