An Electromagnetic Speed Log (EM Log) is a critical navigation instrument used to measure a vessel’s speed through water by detecting electromagnetic fields generated by the ship’s movement. It provides precise speed data essential for navigation, fuel efficiency, and compliance with maritime regulations.
We provide EM Logs from industry-leading brands and handle professional installation.
Accurate calibration and performance verification to ensure reliable readings.
Prompt repair and routine maintenance to maintain system accuracy.
1. How does an Electromagnetic Speed Log work?
It measures speed by detecting the voltage induced in coils by the ship’s movement through water, based on Faraday’s law of electromagnetic induction.
2. How often should EM Logs be calibrated?
Calibration should be performed annually or per manufacturer recommendations to maintain accuracy.
3. Can EM Logs be integrated with other navigation systems?
Yes, EM Logs typically interface with ECDIS, autopilots, and bridge control systems.
4. What are common causes of EM Log failure?
Sensor fouling, electrical faults, and wiring damage are typical issues.
5. Do you provide global service and support?
Yes, our skilled engineers provide worldwide service, repair, and maintenance.
6. Can you supply replacement EM Log parts?
Yes, we stock genuine parts for fast replacement.
7. How long does an EM Log typically last?
With proper maintenance, EM Logs can operate reliably for 10+ years.
8. Is installation complex for EM Logs?
Installation should be done by certified professionals to ensure proper functioning.
9. What brands of EM Logs do you service?
We service major brands including Rotech, Furuno, Kongsberg, and more.
