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.

- Compass adjustment correctors spares
- On-board compass adjustment
- Magnetic compass exchange / temporary loan
- Worldwide delivery of magnetic compass exchange units
Depending on the port and port stay of the vessel, the compass adjuster will usually make a pre-inspection to check the vessel's magnetic compass, last compass deviations table, the ship's compass logbook and check if all the required data and ship's spare compass correctors are available.
Certified ship's compass service and repair
If during pre-inspection the compass adjuster finds any issues with the compass - like an air bubble or tilted card - our team of fully certified compass technicians can overhaul, repair or replace your damaged compass in good time for the vessel to leave without any delay.
Compass adjustment correctors spares
We have the most common types of correctors in stock to ensure fast delivery in the case of missing or damaged parts. We also hold spare magnets for all of the magnetic compasses we stock, so there is no need to cancel the magnetic compass adjustment due to the unavailability of the correct magnets.
Onboard compass adjustment
Once the vessel's magnetic compass is ready for adjusting our compass adjuster will make the necessary arrangements to make the adjustment at sea.
The compass adjuster will keep in close contact with the vessel's Port Agent and will board the vessel prior to departure and will sail with the vessel out to sea where they will perform the compass adjustment during a compass swing or swings 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 will take around 1 hour of swinging the ship. On completion, the compass adjuster leaves along with the ship's pilot.
Depending on the size of the ship, the compass adjustment can also be done inside port limits keeping costs to minimum.
Magnetic compass exchange unit
Our service centre has over 30 of the most common brands of magnetic compasses which can be provided on an exchange basis. These compasses are fully certified and ready for direct installation in ARA area.
This service enables us to solve any magnetic compass issue onboard when time is short, in case of ship's 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 vessel's 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 ship's magnetic compass became damaged.
Worldwide delivery of magnetic compass exchange units
Our service centre has over 30 of the most common brands of magnetic compasses which can be provided on an exchange basis and are ready for shipment to other countries.
Simply install the received exchange unit and send your damaged magnetic compass back to our Rotterdam office. Chargeable costs are typically for repair, shipping and customs clearance.
Because the exchange magnetic compass is of the same maker and type as the vessels magnetic compass there is normally no need for compass adjustment and the deviation will be the same as before the magnetic compass became damaged.
