Certified Marine Magnetic Compass Calibration & Adjustment in Dubai
Under SOLAS Chapter V/Regulation 19.2.1.1, every commercial vessel regardless of size must maintain a properly adjusted standard magnetic compass—or independent Transmitting Heading Device (THD)—to ensure autonomous heading reference completely isolated from shipboard electrical power failure.
Over time, hull structural welding, cargo hold loading of ferrous metals, lightning strikes, and prolonged lay-ups in Middle Eastern waters induce permanent (hard iron) and induced (soft iron) magnetism within the vessel’s hull frame. This causes severe deviation errors on the magnetic compass bowl. Under ISO 25862:2019 standards, a magnetic compass must be swung and re-calibrated whenever deviations exceed 3 degrees, after major structural alterations, or upon annual Class survey expiration. Calling at Dubai, Seanav Marine deploys licensed compass adjusters equipped with Flinders bars, quadrantal soft-iron spheres, heeling error magnets, and optical sighting circles to restore total magnetic accuracy.
Technical Protocols & Compass Servicing Scope in Dubai
- Vessel Swinging & Deviation Compensation: Swinging the vessel through 8 or 16 points of the compass, calculating coefficients A, B, C, D, and E, and adjusting permanent fore-and-aft / athwartship magnets.
- Air Bubble Purging & Fluid Renewal: Inspecting expansion diaphragms, resealing float chamber gaskets, and purging air bubbles using approved compass fluid mixtures.
- Gimbal Freedom & Pivot Jewel Inspection: Checking iridium-tipped pivot points, sapphire bearings, and gimbal ring balance to guarantee smooth float stabilization under heavy sea roll.
- Optical Periscope & Binnacle Dimmer Overhaul: Cleaning reflector mirrors, aligning bridge-to-steering periscope tubes, and rewiring 24V DC / emergency binnacle lamps.
- Official Table of Deviations (Deviation Card): Issuing signed and stamped official deviation cards valid for global international trade and Port State Control (PSC) inspections.

Frequently Asked Questions: Marine Magnetic Compass in Dubai
How fast can licensed compass adjusters attend in Dubai?
Our flag-state approved compass adjusters mobilize within 1 to 2 hours across all berths, terminals, and anchorages at Dubai to execute sea swinging or quay-based compensation.
Can you purge air bubbles and refill compass fluid on site in Dubai?
Yes. We carry specialized Bayol 35 / alcohol-distilled water solutions, expansion diaphragms, and sealing gaskets to purge air bubbles and restore float freedom directly in Dubai.
Do you issue official Classification Society Table of Deviations in Dubai?
Yes. Following vessel swinging, we calculate residual deviations and issue signed, certified Deviation Cards recognized by all IACS classification societies and Port State Control (PSC).
