The Directorate General (DG) of Shipping, India mandates that every seagoing vessel be equipped with a magnetic compass approved by a recognized authority. The compass must be properly calibrated and installed in a suitable location, such as a binnacle on the bridge. It should be readable from the steering position and regularly maintained. DG Shipping […]

Marine compass calibration is essential for ensuring precise heading information. Calibration adjusts the compass to reduce or eliminate deviation caused by nearby magnetic fields. This process is often done by swinging the vessel and recording compass readings on multiple headings. Certified marine technicians use this data to prepare a deviation card or adjust the compensators. […]
Compass correction in India is a technical process performed to eliminate deviation caused by a ship’s magnetic influences. Trained compass adjusters conduct the correction by swinging the vessel and adjusting corrector magnets or compensators. This process is essential to ensure navigational accuracy. Indian marine authorities mandate compass correction as part of safety compliance for seagoing […]
Ships rely on magnetic compasses as essential navigational instruments. Unlike GPS or electronic compasses, the magnetic compass functions independently of external power and satellites, providing reliable directional reference. These compasses are installed in a protective casing known as a binnacle and require periodic correction to account for deviation caused by the vessel’s magnetic field. A […]
