  • Page 20 1. MOUNTING • If the length of the retraction tank (Li) is more than 1 m, install at least one reinforcement rib to prevent damage of the tank and vessel by sea accident. One reinforcement rib should be installed toward the ship’s bow (see the figure below).
  • Page 21 1. MOUNTING • Install a fairing plate to the bottom hull where the transducer projects to protect the transducer from the water pressure. The fairing plate should contact the frame of the hull plate. For the fairing plate, use the same material and thickness as the hull plate. The wooden or plastic material is also available.
  • Page 22 1. MOUNTING For small FRP ship The retraction tank should be mounted in parallel with the ship’s draft. For a small ship, however, the hull has 2 degrees of tilt rising toward the bow. This creates high water pressure in the tank because of the resistance at the rear of the tank well.

  • Page 36: Motion Sensor Ms-100 (Option)

    1. MOUNTING Motion Sensor MS-100 (option) The MS-100 measures ship’s pitching and rolling angles with a sensor, using the principles of the gyroscope. The MS-100 is free from error caused by ship’s vertical and horizontal motion. Therefore, it can be installed at any convenient location.

  • Page 37: Clinometer Bs-704 (Option)

    1. MOUNTING Clinometer BS-704 (option) The clinometer detects ship’s inclination caused by ship’s rolling, pitching and its output is used to stabilize the sonar beam against rolling and pitching. The clinometer is, in principle, a pendulum. It measures the inclination of the ship by sensing the direction of gravity acted on it and therefore when installed on a ship, it should be placed on or near the rotation axes of the ship’s rolling and pitching.
