Maritime vessels rely heavily on radar systems for navigation and safety, particularly during low visibility conditions. The SM-70EN/C1 radar system from Hyundai Welding Co., Ltd. in Pohang, South Korea, is designed to meet the X-Band and S-Band requirements as specified by IMO SOLAS regulations. Utilizing electromagnetic radar technology, this system ensures reliable navigation and collision avoidance. Certified by DNV, the SM-70EN/C1 is engineered to operate with high durability and performance. Common issues that may arise include magnetron end-of-life after 5,000 to 8,000 operating hours, bearing damage on the antenna rotation motor after 30,000 hours, and display backlight failure. Heading marker misalignment and waveguide moisture intrusion due to compromised pressure sealing are also noted. Spare parts such as a spare magnetron should be kept on board, with a lead time of 1 to 3 weeks for replacements. Maintenance recommendations include annual magnetron replacement and antenna bearing lubrication, along with weekly performance monitoring tests as required by IMO regulations. Annual inspections are also advised to ensure the system remains in optimal working condition.
