X-Band Radar (9 GHz) · Radar & ECDIS
Marine radar systems are crucial navigational aids for vessels operating under international maritime regulations. The SikaForce®-611 L20, manufactured by Sika Services AG, is a radar system designed to comply with IMO SOLAS standards for both X-Band and S-Band operations. This radar operates on an electromagnetic medium, ensuring reliable performance across various weather conditions. The system is DNV-approved, providing assurance of its compliance with stringent maritime safety and quality standards. Common issues that may arise with the SikaForce®-611 L20 include magnetron end-of-life after 5,000 to 8,000 hours of operation, bearing damage in the antenna rotation motor after 30,000 hours, failure of the display backlight, heading marker drift, and moisture intrusion in the waveguide due to compromised pressure sealing. To mitigate downtime, it is recommended to keep a spare magnetron on board, with a lead time of 1 to 3 weeks for replacement parts. Regular maintenance includes magnetron replacement every 5,000 to 8,000 hours and annual lubrication of the antenna bearing. Weekly performance monitoring tests are required as per IMO regulations, and an annual inspection ensures ongoing compliance and operational readiness.
