Compass Services

The main reason for compass adjustment and the issue of a new deviation table is an increase in deviations.

Inspections by the Port State Control, Vetting Inspectors and Flag State Audits can also create a need for compass adjustment.

Pre-inspection

Depending on the port and port stay of the vessel, the compass adjuster will usually make a pre-inspection to check the vessels magnetic compass, last compass deviations table, the ships compass logbook and check if all the required data and ships spare compass correctors are available.

Certified ships compass service and repair

If during pre-inspection the compass adjuster finds any issues with the compass like an air bubble or tilted card the ChartCo fully certified compass service department can overhaul, repair or replace your damaged compass in good time for the vessel to leave without any delay.

Compass adjustment correctors spares

If any correctors are missing or damaged we have the most common types in stock for fast delivery. Also we have spare magnets of all types of magnetic compass manufacturers in stock, so there is no need to cancel the magnetic compass adjustment due to the unavailability of the correct magnets.

On-board compass adjustment

Once the vessels magnetic compass is ready for adjusting the qualified compass adjuster will make the necessary arrangements to make the compass adjustment at sea.

The compass adjuster will keep in close contact with the vessels Port Agent and will board the vessel prior to departure and will sail with the vessel out to sea.

There the compass adjuster will perform the compass adjustment during a compass swing(s) and remove/decrease the deviation close to zero. The deviation that is left will be noted on a deviations table and handed over to the master prior to debarkation.

Usually the actual compass adjustment itself will take around 1 hour of swinging the ship. After the compass adjustment, the compass adjuster leaves along with the ships pilot.

Depending on the size of the ship, the compass adjustment can also be done inside port limits keeping costs to minimum.

This service enables us to solve any magnetic compass issue on-board when time is short, in case of ships compass damage or if the vessel is detained by Port State Control for reasons of magnetic compass deficiency.

Because the exchange magnetic compass is of the same quality as the vessels magnetic compass prior to requiring repair or service and deviation correction / compass adjustment, there is normally no need for compass adjustment and the deviation will be the same as before the ships magnetic compass became damaged.
