Doppler Log

A Doppler Log is a device used on ships to measure the speed and direction of water currents relative to the ship’s motion. It works by transmitting an ultrasonic signal from the ship’s hull into the water, and measuring the frequency shift of the signal as it bounces off particles in the water. This frequency shift, known as the Doppler Effect, can be used to calculate the speed and direction of the water currents. In this Doppler Log course, participants will learn the principles of operation, calibration, and maintenance of a Doppler Log. You will also learn how to troubleshoot common issues and interpret the data output from the device. Other topics covered may include the installation of the Doppler Log on different types of vessels, safety considerations, and regulations related to the use of the device. By the end of the course, participants will have a thorough understanding of how to use a Doppler Log to accurately measure water currents, which is essential for safe navigation and efficient operations on board ships. You will also have the skills and knowledge to ensure the proper functioning of the device, which can help prevent costly downtime and repairs.
