  • Page 24: Avoid Protruding Objects Near The Transducer

    The effect of slamming can be reduced by mounting the transducer as deep as possible on the hull. Note Kongsberg Maritime AS takes no responsibility for any damages to the transducer, the cable or the mounting arrangement, caused by slamming. Avoid protruding objects near the transducer Objects protruding from the hull will generate turbulence and flow noise.

  • Page 25: Keep The Transducer Far Away From The Propellers

    When in operation, the noise and cavitation bubbles created by the thruster may make your EA640 transducer useless, almost no matter where it is installed. When the bow thrusters are not in operation, the tunnel creates turbulence. If your vessel is pitching, the tunnel may be filled with air or aerated water in the upper position and release this in the lower position.
  • Page 26 EA640 Installation Manual Transducer Hull length at water line Inclination angle Maximum 1/3 of the hull length at water line (C) If the vessel hull has a bulbous bow, this may well be a good transducer location, but also in this case the flow pattern of the aerated water must be taken into consideration.

The contribution from auxiliary machinery may, however, be considerable, especially if it is in poor shape. The machinery noise can be transmitted to the transducer as: •...
  • Page 30 EA640 Installation Manual Flow noise The upper water layers of the sea contain a myriad of small air bubbles created by the breaking waves. When the hull moves through water it will cause a disturbance, and this will generate friction. The friction zone is called the flow boundary layer. The water flow in this boundary layer may be laminar or turbulent.

  • Page 31: Ambient Noise

    Preparations nearly the same frequency. Interference effects can be observed with all types of waves, for example, light, radio, acoustic, surface water waves or matter waves. https://en.wikipedia.org/wiki/Wave_interference — April 2016 Ambient noise Ambient noise is usually not a limiting factor to the performance of sonars and echo sounders.
  • Page 32 EA640 Installation Manual Note The information here must be considered as general advice. Each system installation must be handled separately depending on the hull design and the other electrical and mechanical systems installed on the vessel. Reducing flow noise • The shape of the transducer (or dome around it) must be as streamlined as possible.
  • Page 33 • Make sure that all units are properly grounded. This is important to avoid electrical noise. • Use shielded cables with correct grounding. • Separate the cables used by the EA640 system from other cables with high voltages, large currents or transients. Place all high voltage power cables in metal conduits. 413764/C...
