Regular maintenance and timely part replacements are crucial for ensuring the reliability of radar equipment on maritime vessels. One such device is the SW-2209 Cored / M21 model, manufactured by Hyundai Welding Co., Ltd. in Pohang. This radar system operates on both X-Band and S-Band frequencies, meeting the IMO SOLAS standards, and uses electromagnetic radar technology. It is approved by DNV, ensuring compliance with stringent maritime regulations. Common issues include magnetron end-of-life after 5,000 to 8,000 hours of operation, bearing damage on the antenna rotation motor after 30,000 hours, and display backlight failure. Heading marker misalignment and water ingress in waveguides due to compromised pressure sealing can also occur. Spare parts such as a spare magnetron should be kept on board for quick replacements, with a lead time of 1 to 3 weeks. Regular maintenance tasks include magnetron replacement every 5,000 to 8,000 hours, annual lubrication of the antenna bearing, and weekly performance monitoring tests as per IMO requirements. An annual inspection is also necessary to maintain optimal performance.
