1.1 Hull Unit
1.1.1 Installation position of hull unit
Discussion and agreement are required with the dockyard and the ship owner in deciding the installation position of the hull unit. When deciding the installation position,
the following points should be taken into account.
1) Select an area where propeller noise, cruising noise, bubbles and interference
from turbulence are at a minimum. Generally, the point at 1/3 to 1/2 of the ship’s
length from the bow on or near the keel is optimum. On-the-keel installation is advantageous for minimizing oil consumption in comparison with off-the-keel. In case
the hull unit cannot be installed on the keel, the center of the retraction tank should
be within 1 m of the keel so as to prevent a rolling effect.
Installation position of hull unit
2) Select a place where interference from other equipment is minimal. The hull unit
should be at least 2.5 m away from the transducers of other equipment.
3) An obstacle in the fore direction not only causes shadow zone but also aerated water, resulting in poor sonar performance.
4) The following space is required around the hull unit for wiring and maintenance. If
the ambient temperature of the unit is below 0°C, the sonar compartment must be
provided with a heater so as to keep the temperature above 0°C.

the inner surface of the tank. The tank guide will hit
the bead, causing motor burn-out. The gap between
the tank and tank guide is 1 mm. Also when installing the tank, orient the welding bead so it faces the
port or starboard side.
1.1.2 Installation of retraction tank
1. MOUNTING
The retraction tank is 1000 mm in length when supplied. Cut the end of the tank referring to the table below so that the transducer is fully protruded beyond the keel when
it is lowered. Refer to the tank installation method at the end of this manual.

The motion sensor measures ship’s pitching and rolling angles with a sensor, using
the principles of the gyroscope. Because it is free from error caused by ship’s vertical
and horizontal motion, it can be installed at any convenient location. However, ship’s
semi-permanent inclination due to loading imbalance cannot be detected. Compensate for this as described in Chapter 3.
1.7.1 Mounting consideration
• Vibration in the mounting area should be minimal.
• Locate the unit away from areas subject to water splash.
• The ambient temperature should not exceed 50°C.
1.7.2 Mounting procedure
Orient the FORE mark on the unit toward the ship’s bow and mount the unit within 5°
of horizontal in all directions. For the offset, see Chapter 3.
