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.

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 ship navigation compass is a primary directional instrument, used to maintain course and heading. It includes magnetic, gyro, and digital variants. A properly mounted and calibrated compass is essential for sea voyages. Indian ships use both analog and digital compasses, often paired with autopilots and repeaters. Regular maintenance ensures precision and compliance.
Compass adjustment services involve the correction of magnetic deviation using soft iron correctors and magnets. Certified compass adjusters perform these adjustments on board to reduce compass error. In India, these services are available at ports like Mumbai, Chennai, and Kochi. A deviation card is usually issued after adjustment, aiding navigators with accurate headings.
Magnetic compass repair in India is a critical service for ships, boats, and marine institutions. Common repairs include fluid replacement, magnet realignment, card repair, and dome sealing. Authorized technicians perform these tasks following IMO and SOLAS guidelines. Repair centers are available at all major Indian ports and shipyards. These repairs ensure compass accuracy, safe navigation, […]
The compass bowl is the main container holding the compass fluid and card. It supports the gimbal system and ensures the compass remains level regardless of the ship’s motion. Damage to the bowl can cause leaks and misalignment. Replacement bowls are available for most major compass models and are offered by Indian marine equipment suppliers […]
A compass cover protects the dome and internal components from dust, UV rays, and mechanical damage when the compass is not in use. Typically made from marine-grade plastic, leather, or fabric, these covers extend the lifespan of the compass. Indian marine suppliers provide custom and standard covers suitable for most binnacle and bracket-mounted models. Using […]
