Recently the doppler sonar speed log has become quite popular for VLCCs built at the Sakaide Works of Kawasaki Heavy Industries, Ltd. However, during their speed trials we occasionally noticed the false readings with the doppler sonar speed log at some speeds, particularly when they are gathering way in the ballast condition. This phenomenon seems to have been caused by the air bubbles contained in the sea water running along the bottom of the ship. The same bubbles can be traced back to the broken waves in front of the bow. This has been veryfied by the streamline tracing by the computer and also by colored liquid drops on a model in the circulating water channel.
