Marine Gyro Compass Annual Overhaul, Sphere Replacement & Class Survey Certification

Under SOLAS Chapter V, Regulation 19.2.5.1 and IMO Resolution A.424(XI), all ships of 500 gross tonnage and upwards must operate a certified gyro compass transmitting true heading to radar, ECDIS, and AIS with settling errors not exceeding ±0.75° × secant latitude. Class-mandated annual servicing requires complete replacement of supporting fluid, carbon brushes, and gasket seals, rotor bearing vibration analysis, optical sensor alignment, and scheduled sensitive element (sphere) exchange (typically 24,000–36,000 operating hours). Certified marine electronics engineers attend vessels at berth, inner/outer anchorages (OPL), or via riding squads across global hubs to ensure zero-deficiency Port State Control (PSC) and IACS Class annual safety navigation survey sign-off.
