System description SYSTEM DESCRIPTION Introduction This chapter provides a brief introduction to the Simrad EQ60 fishery echo sounder system.
Simrad EQ60 System overview Key facts The Simrad EQ60 echo sounders is designed for the professional fishery community implementing the latest innovations. • The EQ60 system is flexible and easy to configure due to the modular design. • Echo sounders ranging from relatively low-cost single beam to large multi-frequency systems can be realised. • Menus and dialogue boxes are operated by a standard mouse or a roller ball. • Large colour liquid crystal displays (LCD) are used.

System description Wave propagation The velocity of sound wave propagation in the sea varies slightly with temperature, salinity and pressure. The velocity varies between 1440 and 1520 m/s in shallow sea water, while a velocity around 1480 m/s can be expected at 1000 m depth. In shallow fresh water the velocity is approximately 1430 m/s. A good average value to be used in the Environment dialogue box is 1470 m/s.
Simrad EQ60 Propagation losses due to absorption are much higher in sea water than in fresh water. Absorption also increases with frequency. At 38 kHz the absorption is 0.5 dB/km in fresh water and 10 dB/km in sea water. At 200 kHz the absorption is 10 dB/km in fresh water and 50 dB/km in salt water. The echo sounder must know which water type is present in order to compensate for these losses correctly. (The dB (decibel) unit has long traditions in underwater acoustics and other fields in physics.
System description Bottom echo A hard flat bottom reflects the transmitted signal as if it were a mirror. The transmitted pulse hits the illuminated bottom area at nearly the same instant, and the echo from different parts of this area arrive back at the surface also at nearly the same instant. Figure 2 Bottom echo The received echo signal is basically an attenuated copy of the short transmit pulse.
Simrad EQ60 The bottom detection algorithm locks to the first good bottom return. The depth at point A rather than the depth along the transducer axis will be output for a sloped bottom. The detected depth value is always smaller than the depth along the transducer axis implying that a safety margin is automatically included. 8 857-164342 / Rev.
System description Observation range Absorption increases dramatically with frequency in salt water. For maximum observation range you should select a low operating frequency, a large transducer and the maximum transmit power. Figure 3 Observation range Typical observation ranges are shown in the figure. Using the Simrad 27-26/21 transducer (27 kHz, 10x13 degrees, 3000 W) you can observe a 60 centimeter cod down to 800 meters, and bottom detection works down to 3800 meters.

Simrad EQ60 Advanced Transceiver This dialogue box is accessed from the Transceiver Settings dialogue box. It displays detailed numeric information characterising the channel. This includes transducer parameters, exact transmit frequency and receiver processing parameters. Parameters The parameters shown in this dialogue box are determined during the transceiver installation procedure. The descriptions are included for information only.
Instruction manual Absorption [dB/km] - This value describes the absorption of sound in the water. The default values are computed according to Francois and Garrison, Journal of Acoustic Society, December 1982. The most important environmental variable affecting this parameter is found in the Environment dialogue box. Bandwidth [Hz] - This is the resulting system bandwidth of the analogue and digital filters in the echo sounder receiver.
Simrad EQ60 Annotation The Annotation dialogue box is opened from the File menu. The EQ60 echo sounder supports these different types of annotation: • Text - use this function to enter your own text. • Time - use this annotation to automatically generate a time marker at specified intervals. • Event - use this annotation to generate an event number with optional addition of time and/or navigation. • External - this function allows automatic annotation from an external source.
Instruction manual Text The annotation text is entered here. Note that you need to have a keyboard connected to the echo sounder. The text can be entered freely, for example ”Dangerous wreck”. When you press the OK button the text is written into the echogram. The next time you open the Annotation dialogue box, the text is cleared, and you must enter new information. Time Click Active to activate automatic time annotation. Enter the desired time interval between the annotations.

Instruction manual BI 500 The BI 500 dialogue box is opened from the Install menu. The EQ60 echo sounder may communicate on an ethernet line with the BI 500 post-processing software. This dialogue box is used to set up the parameters for this communication, and to define which information the BI 500 shall receive. Datagram You can specify which datagrams to be transmitted to the BI 500 computer: Parameter- Check this box if you want to transmit parameter data.
Simrad EQ60 Vessel Log - Check this box if you want to transmit VesselLog datagrams. This datagram is required by BI 500 and is automatically generated based on the vessel speed. You will normally transmit all the datagrams when operating EQ60 together with BI 500. If you do not use the BI 500, do not export any datagrams. The Echogram, Echo trace and Vessel log datagrams are identical to the corresponding datagrams transmitted by the Simrad EK500 echo sounder.
Instruction manual Bottom Detector The Bottom Detector dialogue box is opened when you right-click on the numeric depth value in the Header view on the display. This dialogue box is used to define the upper and lower depth limits most likely to be used during the echo sounder operation. These limits may be used to obtain ”bottom lock” on the depth when the echo sounder is pinging.
Simrad EQ60 Maximum Depth - The search for the bottom echo extends down to this depth whenever bottom track is lost. Enter a slightly larger depth value than the deepest spot you expect to visit in order to avoid annoyingly long ping intervals every time bottom track is lost. A depth value of either 0 or less than the minimum depth disables the bottom detector. Bottom Lost Warning - A warning is activated whenever bottom track is lost.
Instruction manual Bottom Range The Bottom Range dialogue box opens if you click the right mouse button in the range field in the Echogram and Range view while operating with a Bottom Range echogram. The different echograms are explained in the Echogram dialogue box. Range - This parameter controls the vertical depth range across the echogram. Stop Relative Bottom - This parameter controls the depth offset at the lower boundary of the echogram relative to the detected bottom; positive values downwards.
Simrad EQ60 Colour Scale The Colour Scale dialogue box is opened when you right-click on the colour scale in the Header view. This dialogue controls the mapping of echo strength into one out of 12 colours, light blue for weak signals and dark brown for strong signals. Each discrete colour represents a 3 dB range of echo signal strength implying that the next colour is selected every time the echo strength doubles.
Instruction manual Limit gain regulation - Due to the high dynamic range in the EQ60 echo sounder, invidious gain settings may result in unwanted noise. This will also cause the fish size estimates to be erroneous. This gain regulation setting will limit the receiver gain to maximum 100 dB. The limitation will prevent the echo sounder from saturation. Bottom Gain - This parameter controls the display sensitivity of the echo sounder below the detected bottom depth.
Simrad EQ60 Depth Output The Depth Output dialogue box is called from the Heave Sensor, Trawl Interface and Navigation Interface dialogue boxes. These are in turn accessed from the Install menu. It allows you to control the depth data output. Parameters Depth output - Check to enable the depth output.

For the majority of the transducers, the cables are supplied from the manufacturer. These are normally physically fastened to the transducer.
Simrad EQ60 Single frequency, single beam The next two drawings show how to connect a single frequency, single beam transducer to the system. Note that two different connections are made, depending on the rated power output. Low power output is achieved when the GPT is equipped with a single transmitter board. In most systems, this will result in a 2 kW output power, but older GPTs may only be capable of supplying 1 kW. Note: 1) All transducer cables must be run in steel conduits.
Cable layout High power output is achieved when the GPT is equipped with four transmitter boards. In most systems, this will result in a 4 kW output power, but older GPTs may only be capable of supplying 2 kW. Note: 1) All transducer cables must be run in steel conduits. Use flexible conduit closer to the transceiver. 2) Cable shields must be connected to the plug housing. 3) Cable shields must not be connected to ship's ground in the junction box.
Simrad EQ60 Single frequency, dual beam The drawing shows how to connect a single frequency, dual beam transducer to the system. Note Check the transmit power if wide beam is selected in order not to exceed the power capacity on the transducer. Note: 1) All transducer cables must be run in steel conduits. Use flexible conduit closer to the transceiver. 2) Cable shields must be connected to the plug housing. 3) Cable shields must not be connected to ship's ground in the junction box.
Cable layout Dual frequency, single beam The drawing shows how to connect a dual frequency, single beam transducer to the system. Note: 1) All transducer cables must be run in steel conduits. Use flexible conduit closer to the transceiver. 2) Cable shields must be connected to the plug housing. 3) Cable shields must not be connected to ship's ground in the junction box.
Simrad EQ60 Split beam transducer connected as single beam The drawing shows how to connect a split beam transducer to a single beam system. Note: 1) All transducer cables must be run in steel conduits. Use flexible conduit closer to the transceiver. 2) Cable shields must be connected to the plug housing. 3) Cable shields must not be connected to ship's ground in the junction box.

Cable layout PC Transceiver to transducer(s) This cable connects the PC Transceiver board to one or tow transducers. The cable must be run in steel conduits. Use a junction box only if required. Note: 1) All transducer cables must be run in steel conduits. Use flexible conduit closer to the transceiver. 2) Cable shields must be connected to the plug housing. 3) Cable shields must not be connected to ship's ground in the junction box.
Simrad EQ60 Basic cabling requirements Cable trays All permanently installed cables associated with the system must be supported and protected along their entire lengths using conduits and/or cable trays. The only exception to this rule is over the final short distance (max. 0.5 metre) as the cables run into the cabinets/units to which they are connected. These short unsupported lengths are to allow the cabinets to move on their shock mounts, and to allow maintenance and replacements.
Cable layout Radio Frequency interference All cables that are to be permanently installed within 9 m (30 ft) of any source of Radio Frequency (RF) interference such as a transmitter aerial system or radio cabin, must, unless shielded by a metal deck or bulkhead, be adequately screened by sheathing, braiding or other suitable material. In such a situation flexible cables should be screened wherever possible.
Simrad EQ60 Metallic casings, pipes and conduits must be grounded, and when fitted with joints these must be mechanically and electrically grounded. Cable connections All cable connections are shown on the applicable cable plan and interconnection diagrams. Where the cable plan shows cable connections outside an equipment box outline, the connections are to be made to a plug or socket which suits the plug or socket on that particular item of equipment.
Cable layout Cable gland assembly procedure Purpose Cable glands are used whenever a cable passes through a water-tight bulkhead or into a cabinet, to seal the opening through which the cable passes and to protect the cable from abrasion on the edges of the hole. Follow the guidelines detailed here when installing cables through cable glands. Note There are many different types of cable gland on the market.
Simrad EQ60 Note The cable’s outer insulation will extend into the cable gland to a point approximately 5 mm outside the outer surface of the cabinet wall into which the cable gland is secured. 4 5 Taking care not to damage the screening, carefully remove the outer insulation from the required cable length. Leaving an appropriate length of the screen exposed from the insulation, cut off the remainder.
Cable layout Figure 10 Multi-diameter modules (example) After the frame has been mounted, the cables can be pulled through, and in most cases the opening will be large enough even to accept the plugs on the cables. Figure 11 Multi-diameter system - Principal procedure Once the cables are through, each cable is secured with a square module, which is adjusted to fit the cable’s outer diameter. 857-164342 / Rev.
Simrad EQ60 When the required number of modules are installed, the assembly is tightened with a compression unit. This system is available with a large number of various modules and compression units, and it will also comply to screening and EMC requirements.

Transducer installation TRANSDUCER INSTALLATION Transducer location General A single answer to the question where to locate the transducer cannot be given. It depends very much on the vessel’s construction. However, there are some important guide lines. Go deep The upper water layers of the sea contain a myriad of small air bubbles created by the breaking waves. In heavy seas the uppermost 5 to 10 metres may be air-filled, with the highest concentrations near the surface.
Simrad EQ60 layer is thin underneath the forward part of the vessel, and increases in thickness as it moves towards aft. If the sides of the hull are steep, some of the air bubbles in the boundary layer may escape to the sea surface along the vessel sides. It is our experience that a wide and flat bottom, with a rising angle less than around 13 degrees, is prone to giving air problems for the transducer.
Transducer installation sounder useless, almost no matter where the transducer is installed. And when not in operation, the tunnel creates turbulence, and if the vessel is pitching, the tunnel may be filled with air or aerated water in the upper position and release this in the lower position. Therefore, an echo sounder transducer should be placed well away from the bow thruster. Vessel heave Heave is the up and down movement of the vessel.
Simrad EQ60 Summary Some of the above guide lines are conflicting, and each case has to be treated individually in order to find the best compromise. Generally the propeller noise is the dominant factor, and a recommended transducer location is in the fore part of the hull, with maximum distance from the bow equal to one third of the total length of the hull at the water line. → See figure 17.
Transducer installation Ways of mounting the transducer Inclination of the transducer face Incline the transducer face approximately 3 degrees, so that the flowing water meets it directly. This assures laminar water flow. Mounting screws should not be extruding from the transducer, and the space around the screws could be filled with a compound or a locking ring. 857-164342 / Rev.

Simrad EQ60 Transducer blister Other transducers are designed for installation into the hull or in a blister. In general, a blister installation is the recommended method. It brings the transducer below the boundary layer. A blister is illustrated below. Cable service loop Air outlet Min.
Transducer installation The transducer cable penetrates the hull in a stuffing tube, see the figure above. Leave an adequate loop of the cable behind the transducer for easy mounting or removal of the transducer. 5-8° Keel Figure 22 Blister toe-in towards the keel Blister (CD3018) (CD1996) Transducer blister Keel Figure 23 Location of blister relative to the keel 857-164342 / Rev.
Simrad EQ60 In a box keel (CD3008) Vessels with a box keel may use this for transducer installation. The box keel is already the deepest part of the vessel. If the box keel is too narrow to accommodate the transducer, it can be widened, either symmetrically or to one side only. In the last case the installation could also be described as a blister merged into the keel. The figure below illustrates a symmetrical box keel installation.
Transducer installation Retractable transducer Retractable hull units are commonly used for horizontal looking sonars. When not in use, the transducer is retracted into a trunk. The retractable hull unit is more expensive than a blister, but on vessels having a hull where it is difficult or impossible to install a blister, it may be worth-while. A retractable hull unit with transducer is shown below.
Simrad EQ60 Centre board The use of a centre board with the purpose of stabilising the vessel is well known. A centre board is also a superior platform for transducers. Such instrument keels have been built, mainly on research vessels, with a length of 3 m, protruding also 3 m below the hull, see the figure below. At that depth, the water is free of air bubbles up to very high sea states. The vessel is then able to perform reliable acoustic measurements in open sea a larger part of the year.
Transducer installation Flush mounting in a steel tank Flush mounting is used on very large vessels with a hull so deep that no air bubbles are found below the hull, and on vessels operating in shallow harbours or waters, where a protruding blister can not be accepted. The standard procedure for flush mounting on a steel vessel is to weld a steel tank inside the hull, and mount the transducer into this tank. As for a blister, the interior of the tank must be filled with water.
Simrad EQ60 Behind a protective acoustic window Vessels operating in arctic waters need special attention on transducer installation. Floating blocks of ice may damage even a flush mounted transducer face. For this situation Simrad offers ‘’arctic tanks’’ in different sizes. The transducer shown in the figure below is mounted inside the tank behind a strong acoustic window which could be made of polycarbonate. The tank is oil filled.
Transducer installation Inside the hull An installation of the transducer inside the hull, and sounding through the hull, requires a good acoustic contact between the transducer face and the hull. Build a tank around the transducer and fill it with a liquid. Oil used in hydraulic systems is a well suited liquid for this purpose. It contains no gas bubbles and is non-corrosive. The tarnsducer can be mounted inside the hull. A substantial loss must be expected when the sound passes through the hull.
Simrad EQ60 Cable in steel conduit It is strongly recommended to lay a steel conduit from the transducer to the echo sounder transceiver, and draw the transducer cable through the conduit. There are two reasons for this procedure. • First, it will make it easier at a later stage to replace the transducer. • Second, noise and interference from other electrical equipment is greatly reduced. With a steel conduit the installation satisfies the EU regulations for EMC interference.
Transducer installation The tube should be unbroken and watertight from the transducer to above the water line. From there, openings or a junction box can be installed to facilitate drawing of the cable, or to add a cable extension. However, the tube should act as a continuous electrical screen all the way and be connected to the transceiver chassis. Tube dimensions: • minimum 35 mm inner diameter • minimum 6 mm wall thickness (4.5 mm if galvanised).
Simrad EQ60 Handling and maintenance Do not lift the transducer by the cable. Some transducers are delivered with a cover plate on the face for protection during transport. Let this plate stay on as long as possible, but do not forget to remove it before the vessel goes into the sea. An anti-fouling paint may be applied to the transducer face. Because some paint types may be aggressive to the polyurethane in the transducer face, please consult Simrad’s list of approved paints on the next page.
Transducer installation Approved anti-fouling paints This is Simrad’s list of approved antifouling paints on polyurethane transducer housing. From Jotun Paints, Sandefjord Norway: • Antifouling Seamate HB 33 • Antifouling Seamate HB 66 • Antifouling Seamate HB 99 • Racing • Non-stop From International Paints: • Intersleek tie coat + 425 FCS - BXA386/BXA390/BXA391 Grey - HKA563/HKA570/HKA571 Yellow Mix BXA386, BXA390 and BXA391 first, then apply.
