The performance of the magnetic compass should be monitored and deviations to be recorded in a compass deviation book at regular intervals (Ref: IMO Resolution A. 382(X)), ideally at least once every watch and also shortly after a large alteration of course.

What is maintenance of compass?

Proper care will keep a compass functioning for many years. Store a magnetic compass away from computers and other electrical devices that can generate magnetic fields. Exposure to magnetic fields can damage a compass. Keep a magnetic compass away from heaters and do not store in a hot place such as a car.

How long is a compass deviation card valid for?

two years
Finally, according to ISO 25862: 2009 “Ships and Marine Technology”: All SOLAS vessels should have their compass adjusted and at maximum every two years to issue a new deviation card. When a new vessel is commissioned, compass deviation on any heading should be no more than 3° degrees.

What is magnetic compass maintenance?

Checks to be performed include: The compass bowl must be topped up fully with liquid (glycol and distilled water solution) so that no air gaps or bubbles form. Any bubble greater than 20mm should be rectified. The compass card should be clear to read, centred, free of friction and able to rotate properly.

Why spare magnetic compass kept upside down?

How important is it to take Gyro Compass Error frequently?

The compass error should be checked each watch and on every new course to measure the error of the gyrocompass, which is the angle the gyro north makes with the True north to establish trends in deviation on different courses at varying latitudes.

What is the working principle of gyro compass?

Gyrocompass is working with the high speed gyro rotor (gyroscope) to accurately seek the direction of true north. It operates by seeking an equilibrium direction under the combined effects of the force of gravity and the rotation of earth.

What is the basic principles of magnetic compass?

The magnetic compass is working with the principle of Earth’s Magnetic Field and shows the magnetic north and south. The simplest form of compass consists of a magnetized needle free to rotate in a horizontal plane. Such a needle tends to settle in the magnetic meridian.
