Maritime crew and engineers rely on reliable radar equipment to ensure the safety and navigation of their vessels. Hyundai Welding Co., Ltd. (Pohang) offers the SC-81Ni2M / M21 radar system, designed to meet the IMO SOLAS standards with X-Band and S-Band capabilities. This radar operates on the electromagnetic medium and is DNV-approved. 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, display backlight failure, heading marker alignment drift, and moisture ingress in the waveguide due to faulty pressure sealing. To maintain optimal performance, operators should keep a spare magnetron on board and anticipate a lead time of 1 to 3 weeks for replacements. Regular maintenance includes annual magnetron replacement, yearly lubrication of the antenna bearing, and weekly performance monitoring as per IMO requirements. Additionally, an annual inspection is recommended to ensure continued compliance and reliability.
