    Kongsberg EM 710 4 TRANSDUCER ARRAYS This chapter describes the installation of the EM 710 Transmit (TX) and Receive (RX) Transducer Arrays. Drawings showing the installation principles and the physical dimensions are included in the text. Other drawings are included in the Drawing File.

  • Page 29: Installation Philosophy

    Transducer arrays 4.1.2 Installation philosophy The EM 710 Multibeam echo sounder is supplied as a basic echo sounder with two relatively large transducers. While the electronic units are installed using normal tools, the transducer arrays must be located and installed depending on the vessel’s design.
  • Page 30 Kongsberg EM 710 Note it is important to minimize the alongship gap between the RX and the TX arrays to improve the performance at very shallow water (to get overlap between RX and TX footprints). Design the transducer installation method.
  • Page 31 Transducer arrays Table 2 TX1 and TX2 Cable orientation Module type (TX1 / TX2) Serial no. Cable orientation (Port/starboard) Table 3 TX1 and TX2 Cable orientation Module type (TX1 / TX2) Serial no.

  • Page 32 Kongsberg EM 710 the alignment. If the array is mounted with cables pointing towards bow, 180 degrees must be added to the measured heading. In this case the sign of the RX array installation roll and pitch angles must be inverted in the SIS installation menu.

  • Page 33: Locating The Transducer Array

    4.3.2 Propeller noise The propulsion propeller is the dominant noise source on most vessel types. The noise is transmitted through the sea water, and may in extreme cases reduce the maximum range capability of the EM 710. 164851/C...

  • Page 34: Noise From Protruding Objects On The Hull

    Kongsberg EM 710 Figure 4 Sketch of boundary layer underneath the vessel The transducer arrays should therefore be placed far away from the propeller, which means on the forward part of the hull. Positions outside the direct line of sight from the propeller are favourable.
  • Page 35 Transducer arrays Figure 5 Recommended location of the transducer array on the hull The possibility of getting air bubbles in front of the transducer array is the most important factor. If the vessel hull has a bulbous bow, this may well be a good transducer array location, but also in this case the flow pattern of the aerated water must be taken into consideration.

    Mount the steel conduits from the vessel hull and up towards the sonar room and the EM 710 Transceiver Unit. • The steel conduit(s) should have an outer diameter of approximately 219 mm and an inner diameter of approximately 197.0 mm.

  • Page 40: Installing The Mounting Frames

    Kongsberg EM 710 Close the top of the steel conduits with a seal. • Kongsberg Maritime recommends the use of sealing from Roxtec, Bratberg or similar. This system is described in the Appendices chapter in this manual. 4.5 Installing the mounting frames Mounting frames are designed to house the individual transducer modules.

  • Page 41: Installation Accuracy Of Frames

    Transducer arrays Alter the drawings and the design as required to fit the vessel and the chosen installation method. Mount the casings in the blister or integrated into the hull. The mounting frames must be bolted onto the flat bars inside the casing.

    Special tools - None References - Refer to the following drawings in the Drawing File: Note Note that engineers from Kongsberg Maritime must be present to install the transducer modules. 4.6.2 Procedure How to install the RX and TX transducer array modules Observe normal safety precautions for dockyard work.
  • Page 43 Transducer arrays • Secure the transducer module in place with the brackets, one on each side. Use torque approximately 70 Nm. Mount the next transducer module next to the previous. (only applicable for a 0.5 x 1 degree system). • The gap between the individual modules is determined by the appurtenant mounting frame.

  • Page 45: Installation Examples

    To achieve this, you can design and manufacture a streamlined transducer blister, and mount it under the vessel’s hull. This is a well proven way, when refitting a vessel with a EM 710 system. Refer to Hatches for access to the steel conduits (top view) on page 44 for the principles.
  • Page 46 Kongsberg EM 710 • Our recommendation is to place an “debris knife” in the forward end of the blister. Prepare the inside surface protection of the blister. Paint with protective paint, and mount zinc anodes. Mount the transducer blister under the vessel’s hull.

  • Page 47: Gondola

    Installation examples 5.2 Gondola A gondola is a streamlined pod mounted under the hull of the ship. It can either be welded or bolted under the hull plates. The idea is to make a gap between the ships hull and the transducers.

  • Page 48: Flush Mount

    Kongsberg EM 710 Figure 12 Gondola – 1 x 2 degree system 5.3 Flush mount The transducer arrays may be mounted flush with the vessel’s hull. In order to do this, the shipyard must design a framework inside the hull to support the casings. The arrays must then be mounted so that their faces are flush with the outer hull.

  • Page 49: Fairing

    Installation examples 5.4 Fairing The transducer arrays may also be mounted directly under the vessel’s hull and then “streamlined” with fairing. This installation method has proven successful in former multibeam echo sounder installations. The required installation drawings must be made by the installation shipyard or by third-party ship designers.

  • Page 50: System Units

    Uninterruptible Power Supply (UPS) is used to power the Operator Station. 6.1 Operator station The EM 710 Operator Station consists of a Kongsberg PC based work station. Main units are computer chassis, display monitor, keyboard, mouse, units for external data storage.

  • Page 51: Location

    6.2.1 Location The EM 710 Transceiver Unit is normally installed in the vessel’s “sonar room” close to the transducer arrays. This room must be dry and free from excessive dust and vibration. Maximum humidity of 80% is recommended.
