Ship crew rely on maritime radar systems like the SW-5NiLT / M21 from Hyundai Welding Co., Ltd. (Pohang) to navigate safely, especially in challenging weather conditions. This X-Band / S-Band electromagnetic radar is certified by DNV and meets IMO SOLAS standards. The SW-5NiLT / M21 is designed for reliable performance with routine maintenance. A key component, the magnetron, typically requires replacement every 5,000-8,000 hours of operation. To ensure continuous operation, keeping a spare magnetron on board is recommended, with a lead time of 1-3 weeks. Annual lubrication of the antenna bearing and weekly performance monitor tests (as required by IMO) are crucial for maintaining optimal performance. Potential common failures include magnetron end-of-life, antenna bearing wear, display backlight failure, heading marker drift, and moisture intrusion into the waveguide due to pressure issues. Annual inspections are recommended to identify and address potential issues promptly.
