Compass deviation occurs when a magnetic compass’s reading is influenced by the ship’s magnetic fields. It can be corrected by adjusting the compass using a deviation table or compensator. In India, compass deviation correction services are essential for ensuring the compass provides accurate heading information. Regular correction is required to meet DG Shipping and IMO […]
Marine compass correction services in Kochi offer calibration and deviation correction for ships, tugboats, and other vessels. Qualified technicians use advanced equipment to adjust the compass and correct deviations caused by the ship’s metal structure. The service ensures compliance with DG Shipping and IMO standards.
Compasses with compensators are designed to reduce errors caused by magnetic fields aboard the ship. These compasses automatically adjust for deviations caused by metal structures on the vessel. In India, many marine compass suppliers offer models with built-in compensators for accurate navigation, especially on large vessels.
Reading a ship’s magnetic compass involves aligning the lubber line with the ship’s heading and interpreting the direction on the compass card. Mariners must correct readings for deviation and variation to determine the true course. Clear knowledge of cardinal and inter-cardinal points is essential.
Calibrating a ship’s magnetic compass involves identifying deviation by comparing compass bearings with known true headings, usually through a compass swing or transit bearing method. Adjustments are made using corrector magnets. The process must be done by a certified adjuster and documented with a deviation card.
Compass technicians in India are certified professionals offering inspection, repair, calibration, and installation services for magnetic compasses. Many work with DG Shipping-approved companies and provide nationwide services at major ports including Mumbai, Chennai, Kochi, and Visakhapatnam. Their role is crucial for ship surveys and compliance.
Compass calibration must follow procedures defined by DG Shipping, IMO, and SOLAS. It involves checking for deviation, adjusting magnets, and issuing a deviation card. Calibrations should be done by certified compass adjusters and recorded in the ship’s log. Rules also require recalibration after structural changes or magnetic interference. Proper documentation is essential during audits.
Commercial vessels such as cargo ships, tankers, and offshore platforms use high-precision magnetic compasses housed in binnacles with repeaters and calibration tools. Indian marine suppliers offer IMO-approved compasses with optional deviation cards and correction services. These are essential for global navigation, backup, and emergency systems.
A compass servicing company in India specializes in magnetic compass repair, calibration, and adjustment. These companies cater to shipowners, ports, and surveyors, offering on-site and in-house services. They are staffed with trained technicians and equipped with precision tools to issue valid deviation reports and certificates.
