Remote Magnetic
Compass Adjustment
Magnetic compass adjustment done online. Order the service, your officer enters the headings and photos from the bridge, and the platform handles the calculation. A certified adjuster reviews and signs off, and your deviation certificate is issued the same day. No adjuster on board, no port call, no weeks of waiting.
Five steps. No back and forth.
The whole job runs through the platform. What used to be weeks of email and a port visit is now a guided form and a same-day certificate.
Company orders
One request and the vessel receives its login. One-time setup, reuse for every swing after.

Same-day speed
The certificate is issued the day you submit, not the two to three weeks a conventional visit can take.
Legally compliant
Certified adjuster sign-off, produced to SOLAS Chapter V, ISO 25862:2019 and IMO A.382(X).
Available anywhere, anytime
Order on demand. Works at anchor or alongside. No boarding, no waiting for a local adjuster to be free.
Re-swing as often as you need
Unlimited re-swings for two years. Adjust until the compass is right, with no extra charge.
Signed by a certified adjuster
Every certificate is reviewed and digitally signed by a licensed compass adjuster, not just generated by software.
Full audit trail
Every input is timestamped and the certificate is available to download from your dashboard, 24/7.
Who does what.
A compass swing has always been a shared job between the ship and the adjuster. Here is exactly where the line sits, so nobody is guessing on the day.
The ship
Steers each heading in turn, reads the compass against the gyro, records the values, and moves the correctors when instructed. About an hour in reasonable conditions, at anchor or underway.
The platform
Prompts each step in order, checks entries as they are made, runs the deviation calculation and shows the correction to apply. No spreadsheets, no email chains, no transcription errors.
The adjuster
Reviews the result against the limits, decides the correction, takes professional responsibility and signs the certificate. A real check by a licensed adjuster, not an automated output.
You receive
A deviation certificate and card the same day, with corrector positions, residual deviation on every heading and the adjuster's signature. Delivered to ship and office.
And afterwards
Unlimited re-swings for two years, renewal reminders before the next due date, and every certificate downloadable from your dashboard at any time.
What you skip
The port call, the travel and attendance cost, the agency time, and the weeks spent waiting for an adjuster to be free in your area.
A certificate that stands up.
Under SOLAS Chapter V, every vessel must carry a properly adjusted standard magnetic compass and keep a current deviation table on board at all times. The adjustment itself is the work of a duly authorised, certified compass adjuster.
Northy meets both. The data is processed to ISO 25862:2019 limits and IMO A.382(X) standards, and every certificate is reviewed and signed off by a certified adjuster before it is issued.
Two years is the floor, not the rule.
ISO 25862:2019 requires a SOLAS vessel's compass to be swung, adjusted and issued a fresh deviation card at least every two years. That interval is the baseline every ship works from, and a compass that has behaved perfectly for two quiet years is still due the day it runs out.
Dry-docking or structural steel work. Welding and hull work change a ship's magnetic signature.
Bridge equipment added, moved or removed. New electronics can shift deviation overnight.
Magnetically significant cargo carried, such as steel coils or iron ore.
First installation on a newly built or newly fitted vessel.
Lay-up, a long idle period, or a large change in magnetic latitude.
Deviation past the permitted limit on any heading, or whenever the master judges it necessary.
A vessel leaving dry dock is due immediately, no matter how recently it was last swung. Some regimes are stricter than the two-year baseline: the Panama Canal, for example, requires a deviation card issued within the previous twelve months for vessels of 150 gross tons and over. Where two rules overlap, the shorter interval applies. We cover every trigger in detail in our article on how often a magnetic compass must be adjusted.
Flat pricing. No travel charges.
Conventional adjustment typically runs €600 to €750 plus the cost and delay of getting an adjuster to the ship.
The things people ask first.
Is a remotely adjusted compass certificate legally valid?
One flag administration puts it in writing. The Republic of the Marshall Islands states in Marine Notice MN-2-011-32 that all compass adjustments, including those using remote services, must be carried out by a qualified compass adjuster. Remote is contemplated directly, with the same condition applied to everyone.
What does the crew actually have to do?
What the platform adds is structure: each step is prompted in order, readings go into a guided form rather than onto a scrap of paper, and nothing is left to interpretation. No prior experience is needed. If an officer can steer a heading and read a compass, they can complete a swing.
Does an adjuster need to come on board?
What the adjuster brings is judgment, not manual labour. Separating a ship's permanent and induced magnetism, deciding what to correct, and taking professional responsibility for the result is analytical work. It travels.
What conditions do we need for the swing?
Because you are not waiting for an adjuster to be free and in your area, the swing happens when it suits the vessel's schedule rather than the other way round. That is usually the difference between a compass adjusted on time and one adjusted whenever somebody could get to it.
How long does it take?
Compare that with a conventional visit, where the elapsed time is rarely the work itself. It is finding an adjuster with availability, scheduling around the vessel's rotation, arranging attendance and travel, and waiting for the certificate afterwards. Two to three weeks end to end is normal.
What do we receive at the end?
It is delivered to the ship and to your office dashboard, and can be downloaded again at any time.
What if the first swing is not within limits?
Occasionally a compass cannot be brought within limits at all, because of a mechanical fault, poor siting, or a genuine magnetic problem with the vessel. In that case you get a clear technical finding explaining what is wrong and what needs to happen next. That is more useful than a certificate that quietly hides the issue.
When is our compass due?
Some regimes are stricter. The Panama Canal requires a deviation card issued within the previous twelve months for vessels of 150 gross tons and over. Where two rules overlap, the shorter interval applies.
Which flag states accept it?
The certificate is produced to SOLAS Chapter V, ISO 25862:2019 and IMO A.382(X), and signed by a certified compass adjuster. If a provider cannot tell you which standards their certificate is produced to and who signed it, that is your answer.
What if the compass needs repair rather than adjustment?
We will say so if that is what we find, and tell you exactly what the problem is, rather than issuing a certificate on an instrument that should not be in service.
What does it cost?
Conventional adjustment typically runs €600 to €750 before you add the cost of getting an adjuster to the ship: travel, attendance, agency time, and the schedule disruption of waiting for a slot. Those are the costs that disappear.
How do we order?
For a fleet, every vessel sits under one company account with a shared dashboard, so the office can see which certificates are current and which vessels are coming due.
