MOUNTING

1.1Hull Unit

General mounting considerations

Noise and air bubbles will affect performance.

Keep the transducer away from oil. Oil can corrode the cable.

Do not expose the transducer to hot water. Hot water can damage the trans- ducer.

Do not turn on the equipment with the transducer exposed to air. Exposing the transducer to air may damage it.

Installation position considerations

Discussion and agreement are required with the dockyard and ship owner in deciding the location for the hull unit. When deciding the location, take into ac- count the following points:

Select an area where propeller noise, cruising noise, bubbles and interference from turbulence are minimal. Generally, the point at 1/3 to 1/2 of the ship’s length from the bow or near the keel is the best. On-the-keel installation is advantageous for minimizing oil consumption in comparison with off-the-keel. If the hull unit cannot be installed on the keel, the center of the retraction tank should be within 1 meter of the keel to prevent a rolling effect.

Figure 1-1 Installation location for hull unit

Select a place where interference from the transducers of other sounding equip- ment is minimal. The hull unit should be at least 2.5 meters away from the transducers of other sounding equipment.

An obstacle in the fore direction not only causes a shadow zone but also aer- ated water, resulting in poor sonar performance. Be sure to locate the trans- ducer well away from any obstacle in the fore direction.
