Simrad Echo sounder transducers

TRANSDUCER LOCATION

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 h eavy seas the uppermost 5 to 10 metres may be air-ﬁlled, with the highest concentrations near the surface. Air bubbles absorb and reﬂect the sound energy, and may in worst cases block the sound transmission totally. Therefore, mount the transducer at a deep position on the hull.

Consider the situation when the vessel is unloaded, and when it is pitching in heavy seas.

WARNING The transducer must never be lifted free of the

water surface.

Not only will the sound transmission be blocked, but the transducer may be damaged by slamming against the sea surface.

Another reason to go deep is cavitation in front of high power transducers. Cavitation is the formation of small bubbles in the water due to the resulting local pressure becoming negative during parts of the acoustic pressure cycles. The cavitation threshold increases with the hydrostatic pressure.

Vessel heave

Heave is the up and down movement of the vessel. It disturbs the echo traces in the echogram, so that a ﬂat bottom is displayed as a wave. A transducer location in the middle of the vessel minimises the inﬂuence of vessel roll a nd pitch.

Noise from protruding objects on the hull

Objects protruding from the hull, such as zinc anodes, sonar transducers or even the vessel’s keel, generate turbulence and ﬂow noise. Also holes and pipe outlets are noise sources. They may act as resonant cavities amplifying the ﬂow noise at certain frequencies. Do not place an echo sounder transducer in the vicinity of such objects, and especially not close behind them.

For the same reason, it is very important that the hull area around the transducer face is as smooth and level as possible. Even traces of sealing compound, sharp edges, protruding bolts or bolt holes without ﬁlling compound will create noise.

6

851-160164/H

Boundary water layer

When the vessel forces its way through the sea, the friction between the hull and the water creates a boundary layer. The thickness of the boundary layer depends upon vessel speed and the roughness of the hull. Objects protruding from the hull, and dents in the hull, disturb the ﬂow and increase the thickness of the boundary layer. The ﬂow in this boundary layer may be laminar or turbulent. A laminar ﬂow is a nicely ordered, parallel movement of the water. A turbulent ﬂow has a disorderly pattern, full of eddies. The boundary layer increases in thickness when the ﬂow goes from laminar to turbulent. The ﬁgure below illustrates the boundary layer of a vessel moving through the water.

Transducer location

(CD17004P)

Boundary water layers: (A) = Turbulent ﬂow (B) = Laminar ﬂow (C) = Air bubbles in the water

Furthermore, air bubbles in the sea water are pressed down below the hull and mixed into the boundary layer. The boundary 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. In any case a transducer location in the forward part of the hull is preferred in order to minimise the inﬂuence of the boundary layer.

Propeller noise

The propulsion propeller is the dominant noise source on most ﬁshing vessels, research vessels, merchant vessels and pleasure crafts. The noise is transmitted through the sea water. For this reason, the transducer should be placed far away from the propeller, which means on the fore part of the hull. Positions

BAC

Simrad Echo sounder transducers

outside the direct line of sight from the propeller are favourable. On small vessels with short distances it is advised to mount the transducer on that side of the keel where the propeller blades move upwards, because the propeller cavitation is strongest on the other side. The cavitation starts most easily when the water ﬂows in the same direction as the propeller blade, and that is to some degree the case at that side of the keel where the propeller blades move downwards.

Bow thruster propellers are extremely noisy. When in operation, the noise and cavitation bubbles make the echo 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.

Inclination of the transducer face

Ideally, the transducer face should be mounted in parallel with the sea surface when the vessel is in normal trim, as this will provide the most accurate echo information. However, it is also very important that the w

In order to ensure laminar ﬂow, the transducer face may be tilted slightly upwards in relation to the water ﬂow. This allows the ﬂowing water to meet the face directly, and assures laminar ﬂow. The inclination angle must however be determined carefully. The angle must be small on transducers with narrow beam angles. As a rule of thumb, mount transducers with beam angles smaller than seven degrees with minimum inclination angle. The smaller beam angle your transducer has, the smaller the inclination angle can be.

Ensure that you do not mount the transducer with a negative inclination angle. This may cause turbulence under the transducer face, and reduced echo sounder performance.

ater ﬂow over the transducer face is laminar.

Summary and general recommendation

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.

WAYS OF MOUNTING THE TRANSDUCER

There are many different ways to mount the transducer.

External mounting on page 11 Transducer blister on page 16 Box keel on page 22 Flush mounting in a steel tank on page 24 Acoustic window on page 26 Inside the hull on page 28 Drop keel on page 30 Retractable t ransducer on page 31

851-160164/H

External mounting

Certain transducers have a streamlined housing, and these are designed for installation outside the hull.

These transducers are mainly used on smaller vessels. A location approximately 0.5 m aside from the keel may be adequate for the passage of water between the keel and the transducer. The ﬁgures illustrate external mounting of transducers on steel hulls and on wood or polyester hulls respectively.

Smooth surface

Ensure that the surface of the transducer face, the hull plating and putty around the transducer is as even and smooth as possible. Obstructions on these surfaces will create problems with turbulant ﬂow.

Mounting screws must not be extruding from the transducer, and the space around the screws must be ﬁlled with a compound (C) and/or a locking ring.

Steel hull

A fairing (A), made by the shipyard, is placed between the transducer and the hull. It is required in order to adapt for the deadrise angle of the hull, and it will also house a cable service loop (B). The fairing can be made of wood or steel, and should have the same outline dimensions as the transducer. Remember to create an air outlet (E) on the fairing, and to ﬁll the bolt holes with a ﬁlling compound to ensure a smooth transducer surface.

Hull with ﬂat bottom

If the vessel’s hull is ﬂat you do not need a fairing. The transducer is then be bolted directly to the hull using two bronze or stainless steel bolts (I) and a cable bushing. Note that the cable bushing must be mounted with proper gaskets (4) under and over the hull, as well as sealing c ompound (J) around its body. Also, ﬁll the bolt holes with a ﬁlling compound to ensure a smooth transducer surface.

Toe-in

The primary consideration must be to allow laminar water ﬂow. In most cases t his is achieved by placing the transducer (A) parallel with the keel (C). However, if the transducer is located close to t he bow, the front of the transducer may have a few degrees (5 to 8°) toe-in towards the bow. If you have a planing hull, the toe-in must be 0°.

Transducer blister

With a transducer with circular housing, one recommended installation method is by using a blister. The transducer blister must be designed and manufactured by the installation shipyard to ﬁt the vessel’s size and hull shape.

Mounting and clamping rings

Circular transducers may be provided with mounting and clamping rings, or with drawings to allow for local production of these. The m ounting ring is welded to the hole in the transducer blister, while the clamping ring ﬁts around the edge of the transducer body. Bolts through the clamping ring into the mounting ring w ill then secure the transducer between them. Note that several transducers use direction guides to allow correct mounting.

Smooth surface

Mounting screws or bolts must not be extruding from the transducer blister. Ensure that the surface of the transducer face, the blister, the hull plating and putty around the transducer is as even and smooth as possible. Obstructions on these surfaces will create problems with turbulant ﬂow.

Horizontal support bar

Large diameter transducers must be ﬁtted with a horizontal support bar. This bar can be secured to the mounting ring using threaded rods.

851-160164/H

Ways of mounting the transducer

Example: Large transducer

The illustration below shows a typical transducer blister designed for a large t ransducer. Note that due to the physical size of the t ransducer, a U-shaped support bar (E) is used to support the transducer. The purpose of this support is to prevent the transducer from being pushed up into the blister in heavy seas.

851-160164/H 19

Simrad Echo sounder transducers

Common guidelines

The best performance is obtained with a blister height of 40 cm or more. A streamlined shape and rounded edges reduce the ﬂow noise. A vertical leading edge or front will guide the aerated water t o the sides of the blister. The orientation of the blister should follow the water ﬂow.

The interior of the blister must be ﬁlled with sea water. Use drainage holes in the bottom and an air outlet on the top. The water pressure behind the transducer will then compensate for the outside pressure during vessel movements in rough sea.

Large diameter transducers must be ﬁtted with a horizontal U-shaped support bar. This bar can then be secured to the mounting ring using threaded rods.

The transducer cable penetrates the hull in a stufﬁng tube. Leave an adequate loop of the cable behind the transducer for easy mounting or removal of the transducer.

Toe-in

The primary consideration must be to allow laminar water ﬂow. In most cases this is achieved by designing the blister in parallel with the keel. However, if the blister is located close to the bow, the front of the blister may have a few degrees toe-in towards the bow.

Physical location

The blister is placed on one of the sides of the hull, and the distance from the keel is a trade off between a close distance giving a turbulent ﬂow of water in a narrow passage, and a large distance bringing the transducer higher up a nd also more affected by vessel roll. Normally a distance of approximately 1 m is a good compromise.

851-160164/H

Ways of mounting the transducer

Observe the horizontal and vertical distances (X and Y) between the keel and the transducer blister. On a medium sized vessel, the horizontal distance (X) should be approximately 1 meter. The vertical distance (Y) must in general be as small as possible. This is important to prevent the keel from shadowing the transducer beam in shallow waters.

Box keel

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.

Mounting and clamping rings

Circular transducers may be provided with mounting and clamping rings, or with drawings to allow for local production of these. The mounting ring is welded to the hole in the box keel, while the clamping ring ﬁts around the edge of the transducer body. Bolts through the clamping ring into the mounting r ing will then secure the transducer between them. Note that several transducers use direction guides to allow correct mounting.

Smooth surface

Mounting screws or bolts must not be extruding from the box keel. Ensure that the surface of the transducer face, the box, the hull plating and putty around the transducer is as even and smooth as possible. Obstructions on these surfaces will create problems with turbulant ﬂow.

Horizontal support bar

Large diameter transducers must be ﬁtted with a horizontal support bar. This bar can be secured to the mounting ring using threaded rods.

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 ﬂushmountingonasteelvesselis to weld a steel tank inside the hull, and mount the transducer into this tank.

Mounting and clamping rings

Circular transducers may be provided with mounting and clamping rings, or with drawings to allow for local production of these. The m ounting ring is welded to the hole in the hull plating, while the clamping ring ﬁts around the edge of the transducer body. Bolts through the clamping ring into the mounting r ing will then secure the transducer between them. Note that several transducers use direction guides to allow correct mounting.

Smooth surface

Mounting screws or bolts must not be extruding from the hull plating. Ensure that the surface of the transducer face, the hull plating and putty around the transducer is as even and smooth as possible. Obstructions on these surfaces will create problems with turbulant ﬂow.

Horizontal support bar

Large diameter transducers must be ﬁtted with a horizontal support bar. This bar can be secured to the mounting ring using threaded rods.

Water ﬁlled

As for a blister, the interior of the tank must be ﬁlled with water. This can be accomplished by air release through a steel tube, which is extended either to open air 1.5 m above the water line or to the water outside the hull at a point higher than the tank interior. If the tube is extended to open air, drainage must be provided with leakage at the transducer ﬂange or a separate hole in the tank bottom.

Simrad Echo sounder transducers

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.

Mounting and clamping rings

Circular transducers may be provided with mounting and clamping rings, or with drawings to allow for local production of these. The mounting ring is welded to the hole inside the steel tank, while the clamping ring ﬁts around the edge of the transducer body. Bolts through the clamping ring into the mounting ring w ill then secure the transducer between them. Note that several transducers use direction guides to allow correct mounting.

Smooth surface

Mounting screws or bolts must not be extruding from the acoustic window. Ensure that the surface of the window, the hull plating and putty around the transducer is as even and smooth as possible. Obstructions on these surfaces will create problems with turbulant ﬂow.

Inside the hull

The transducer can also be mounted 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.

Typical values of the two way loss are 3 dB for polyester, 6 dB for a luminium and 10 dB for steel. Hulls made of wood or a sandwich type with foam in the middle, attenuate the sound so much that through hull sounding must be regarded as impossible. The loss varies with the distance between transducer face and the hull. The best result is obtained when the distance is half a wavelength. Consult Simrad for advice. In addition to the loss, the beam pattern is degraded, because a larger area of the hull is set into vibrations.

Mounting and clamping rings

Circular transducers may be provided with mounting and clamping rings, or with drawings to allow for local production of these. The mounting ring is welded to the hole inside the steel tank, while the clamping ring ﬁts around the edge of the transducer body. Bolts through the clamping ring into the mounting ring w ill then secure the transducer between them. Note that several transducers use direction guides to allow correct mounting.

Drop keel

The use of a drop keel with the purpose of stabilising the vessel is well known.

A drop keel is also a superior platform for echo sounder transducers. Such instrument keels have been built, mainly on research vessels, often protruding as far as three meters below the hull. 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.

Retractable transducer

Hull units allowing the transducer to be lowered and hoisted are commonly used for horizontal looking sonars. When not in use, the transducer is retracted i nto a trunk.

The retractable hull unit is more expensive than a blister, but on vessels with a hull where it is difﬁcult or impossible to install a blister, it may still be worth while. The principles of a hull unit with a retractable transducer is shown below.

Vessels without a keel and with a wide, ﬂat bottom is an example where a retractable hull unit can be the only acceptable method for bringing the echo sounder transducer below the boundary layer.

Simrad Echo sounder transducers

CABLE GLANDS

The transducer cable must pass through the hull using approved cable glands for the type of vessel in question.

A steel cable gland is normally used on professional vessels with steel hulls. A bronze cable gland can be delivered as an option for vessels with wood or ﬁbreglass hulls. Vessel not to be classiﬁed can as an option use a cable gland made of plastic.

Note

Simrad strongly recommends that a length of conduit is ﬁtted around transducer cable glands made of steel or bronze and extended over the water-line inside the vessel. This precaution reduces the danger of ﬂooding in the event of gland failure and transducers installed in this manner are also easier to replace.

Some vessels may experience difﬁculties ﬁnding suitable areas of the hull for mounting transducer cable glands due to existing water tanks, concrete ballast or other obstacles. A possible solution in such cases is to run the transducer cables in a steel conduit aft along the hull until a suitable cable gland location is available. The respective cable gland can then be installed as described in the following instructions.

Note

Simrad takes no responsibility for the correct installation of cable glands, associated hull modiﬁcations and/or structural support of transducer cable penetration. These activities are subject to individual approval by the respective classiﬁcation society for the vessel in question.

Order numbers

The cable glands described in this chapter are available as kits from Simrad. Observe the following order numbers.

Simrad Echo sounder transducers

Cable splicing

If you need to cut or lengthen the transducer cable, you must splice it correctly. The cable between the junction box and the transceiver must then be supplied by Simrad, and this must be the same type as used on the transducer(s).

Note

Do not solder the wires together with only electrical tape for insulation, as this will result in electrical noise and reduced operational performance.

To splice the cable, use a metal junction box with EMC cable glands and a terminal block. The terminal block must provide solid fastening of the cable ends as well as sufﬁcient insulation between the wires.

Note

We recommend that the cable screen is connected to the junction box chassis using the EMC cable glands, but if you do this, the junction box chassis m

STEEL CONDUIT

It is strongly recommended to lay a steel conduit from t he transducer’s cable gland to the echo sounder transceiver, and to pull the transducer cable through this conduit. There are two reasons for this.

• 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 will satisfy the EU regulations for EMC interference. Without a steel conduit, there is a risk of reduced echo sounder performance.

The steel conduit must be unbroken and watertight from the transducer to above the water line. From there, the cable can be pulled further, or a junction box can be installed to facilitate further connections. Note that the steel conduit must act as a continuous electrical screen all the way. To ensure proper shielding, the conduit must be electrically connected to the echo sounder transceiver chassis.

Steel conduit

Steel conduit dimensions:

• minimum 35 mm inner diameter

• minimum 6 mm wall thickness (4.5 mm if galvanised)

If two or more transducers are installed close to each other it is possible to pull their cables in the same steel conduit, provided the conduit diameter is increased accordingly. However, for easy replacement it is recommended that each transducer has its own steel conduit.

Simrad Echo sounder transducers

HANDLING AND MAINTENANCE

Note

Do not lift the transducer by the cable. Do not expose the transducer to direct sunlight. Do not expose the transducer to excessive heat.

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 l ist of approved paints.

Note

Arctic tanks have acoustic windows made of polycarbonate. These must neither be painted nor cleaned with chemicals.

During dry docking of the vessel, the transducer face may be cleaned for shells and other marine fouling. Be careful not to make cuts in the transducer face. Use a piece of wood or a very ﬁne grade emery paper.
