Crew members and engineers on board rely on radar systems like the SC-71CA / C1 from Hyundai Welding Co., Ltd. (Pohang) for safe navigation and compliance with international maritime regulations such as IMO SOLAS. This radar system operates in both X-Band and S-Band frequencies using electromagnetic waves. It is certified with DNV approval. Common issues that may arise include magnetron end-of-life after 5,000 to 8,000 hours of operation, bearing damage to the antenna motor after 30,000 hours, and backlight failure in the display. Additionally, heading marker drift and moisture intrusion in waveguides due to compromised pressure sealing can occur. Maintenance tips include keeping a spare magnetron on board for quick replacement, ensuring annual lubrication of the antenna bearings, conducting weekly performance monitor tests as required by IMO, and performing an annual inspection.
