Important As with all other advanced instruments, there are a few important things that you must be aware of.

Before you switch on the EK60

Before you power up the EK60, make sure that the transducer is submerged in water!

Caution

You must never power up the EK60 when the ship is in dry dock. The transducer will be damaged if it transmits in open air.

When the EK60 is not used

When you do not use the EK60, switch off the display and the Processor Unit.

If you know that you will not use the EK60 for a long time, we recommend that you also switch off the transceiver(s). Since each transceiver is not provided with a power switch, you must either disconnect the power cable, or disengage the relevant circuit breaker(s).

When you are docking your vessel

If the transducer is activated when out of water it may be damaged beyond repair. It is therefore very important that the EK60 system remains switched off when the vessel is in dry dock, and that no one tries to use it.

To ensure that this can not happen, disconnect the power supply cable to the either the Processor Unit or the transceiver(s) - or both! You may also remove the circuit breakers on the AC mains supply to the EK60 transceiver(s). Do this before the vessel is placed in the dry dock!

As an extra safety measure, the EK60 is by default powered up with the transmit power disabled.

If something breaks down

If you believe that something has broken down, contact your local dealer. They will be able to assist. A list of all our dealers is provided on our website.

• http://www.simrad.com

If you are unable to contact a dealer, observe the support information in this manual.

When you wish to switch off the EK60

You must NEVER switch off the EK60 by means of the on/off switch on the Processor Unit. You must ALWAYS exit the EK60 program by clicking Exit on the File menu.

http://www.simrad.com

850-164696/B 13

WARNING

If you power down the EK60 by means of the power switch on the Processor Unit you may damage the software program and the interface parameters used to communicate with external devices.

Transducer handling

A transducer must always be handled as a delicate item. Wrongful actions may damage the transducer beyond repair.

Observe these rules:

• Do not activate the transducer when it is out of the water.

• Do not lift the transducer by the cable.

• Do not step on the transducer cable.

• Do not handle the transducer roughly, avoid impacts.

• Do not expose the transducer to direct sunlight or excessive heat.

• Do not use high pressure water, sand blasting, metal tools or strong solvents to clean the transducer face.

Display description A display is a required part of the Simrad EK60 Scientific Echo Sounder system.

Any commercial display can be used with the EK60 Scientific Echo Sounder, provided that the display meets the minimum requirements. If you intend to use many views simultaneously, we suggest that you purchase a large high-resolution display.

Note

The display is not a standard part of the EK60 delivery.

The chosen display must be designed for maritime use, and it must meet the minimum performance specifications. You must also make sure that the chosen display supports the video formats provided by the Processor Unit.

Tip

If you wish to see several EK60 views simultaneously, you may wish to obtain a large display with high resolution. The EK60 software supports all display sizes. The fidelity of your presentations depends on the resolution and quality of the graphic adapter in the computer, as well as the quality of the display.

18 850-164696/B

Processor Unit description The Processor Unit is the computer that controls the EK60 system. It is a vital part of the Scientific Echo Sounder system.

Note

The Processor Unit is not a standard part of the EK60 delivery.

In this publication, the computer is referred to as the Processor Unit.

The operating system must be Microsoft Windows® 7.

The computer must be designed for rugged use, and the construction must be able to withstand the vibrations and movements of a vessel.

The computer must comply to the requirement specifications provided by Microsoft for their operating systems. It must also provide the necessary interface facilities (serial lines and Ethernet connections) that your EK60 will need to communicate with peripheral systems.

A high quality Ethernet adapter is required.

The Ethernet adapter communicating with the General Purpose Transceiver (GPT) must offer a Receive Buffers function. This parameter must be set to its maximum value if more than one General Purpose Transceiver (GPT) is used.

The Processor Unit is normally mounted on the bridge or in a scientific laboratory.

Tip

A suitable computer may be provided with the EK60 system.

The computer is designed for rugged use, and customized by Kongsberg Maritime.

Except from the fans, it contains no moving parts. It is based on a commercial design, but the software and hardware has been specified and assembled by Kongsberg Maritime to suit the EK60 requirements.

It is set up with all necessary software.

The computer holds multiple USB ports for use with future software upgrades.

These USB ports will also allow you to export screen captures and recorded data from the EK60.

Consult your dealer or agent for more information.

850-164696/B 19

Ethernet switch A high capacity Ethernet switch is a key component of the EK60 system.

If you use more than one General Purpose Transceiver (GPT) in your EK60 system, you must use an Ethernet switch to connect each General Purpose Transceiver (GPT) to the Processor Unit.

The Ethernet switch is by default not included in the EK60 delivery, but this is a commercial item that can be purchased locally.

Note

Make sure that your selected switch has a large bandwidth capacity. Minimum 1 Gb (1000BASE-T) is required. You must also make sure that all Ethernet cables are type Cat 5e or better. A slower switch - or low quality cables – will decrease the operational performance of the EK60.

1000BASE-T (also known as IEEE 802.3ab) is a standard for gigabit Ethernet over copper wiring. Each 1000BASE-T network segment can be a maximum length of 100 meters (330 feet), and must use Category 5 cable or better (including Cat 5e and Cat 6).

General Purpose Transceiver (GPT) description The EK60 General Purpose Transceiver (GPT) is provided to transmit the acoustic energy into the water. To do this, the transceiver computes and generates the electric signals sent to the transducer to form a transmission - a 'ping'. After each transmission, it will receive the echoes from the objects in the water column and/or the seabed. These echoes are filtered and amplified, and then converted to digital format.

The EK60 General Purpose Transceiver (GPT) comprises a rugged box providing all necessary transmitter and receiver electronics.

The receiver is designed for low noise, and it can handle input signals spanning a very large instantaneous dynamic amplitude range. All targets are correctly measured and displayed.

A high quality Ethernet cable connects the General Purpose Transceiver (GPT) to the Processor Unit. The distance between the Processor Unit and the transceiver can be extended up to maximum 70 meters. If a longer cable is required, cut it in half, and insert an Ethernet switch to provide buffer amplification.

20 850-164696/B

If more than one General Purpose Transceiver (GPT) is used, a small high capacity Ethernet switch is required to connect the transceivers to the Processor Unit.

In order to avoid electrical noise, certain transceiver configurations are supplied with an external power supply.

Transducers The EK60 Scientific Echo Sounder can be used with all our single beam and split beam transducers.

Kongsberg Maritime can provide a large range of efficient and accurate Simrad transducers for fishery and fishery research applications.

A wide range of operational frequencies is available.

Simrad transducers are designed to work optimally across a large bandwidth and in demanding environments. For scientific echo sounders, we divide the features of the transducers into three main categories; split beam, wideband and depth rated. Several transducers will fit more than one category.

For more information about the transducers provided by Kongsberg Maritime, consult the Simrad website.

Split beam, wideband and depth rated transducers Simrad transducers are designed to work optimally across a large bandwidth and in demanding environments. For scientific echo sounders, we divide the features of the transducers into three main categories; split beam, wideband and depth rated. Several transducers will fit more than one category.

Topics Split beam transducers, page 21

Wideband transducers, page 22

Depth rated transducers, page 22

Physical dimensions versus beam opening, page 23

Split beam transducers A split beam transducer is design to transmit the acoustic pulse using one beam, while receiving the echoes in three or four individual channels.

Variations in phase of the returned echoes enable us to locate the target within the acoustic beam. Once you know the location of a target you can make up for variations in the beam patterns, and in the end you can record calibrated target tracks within the acoustic beam.

Simrad commercialized this technology in the 1980’s. Our split beam echo sounders are now used to record data for marine resource management worldwide.

For more information about the split beam transducers provided by Simrad, consult our website.

The installation of the transducer (or transducers) is not described in detail in this manual. Please refer to the documentation provided with each transducer.

Related topics Transducers, page 20 Additional required items, page 26

Wideband transducers A wideband transducer can transmit and receive on a large frequency range, for example 45 to 90 kHz, 85 to 170 kHz or 150 to 300 kHz. This means you only need three transducers to cover the entire frequency range from 45 to 300 kHz.

In order to design a transducer that is capable of providing this frequency range, composite technology is our preferred production technique. All our wideband transducers are produced using composite material.

When a wideband transducer is combined with a wideband transceiver it is possible to make sweep transmissions. In these, the transmit frequency continuously increases throughout the transmitted pulse. This functionality is often referred to as a "chirp".

It is also possible to transmit on several discrete frequencies, one at a time.

If you are an advanced user, you can define an arbitrary signal, such as a dolphin’s click.

This opens up a whole new world in interpretation of the echo, taking a great step forward towards the goal of providing a species identification echo sounder, or "ecosounder".

For more information about the wideband transducers provided, consult the Simrad website.

• http://www.simrad.com Note

The Simrad EK60 Scientific Echo Sounder does not support wideband transmission and reception.

The installation of the transducer (or transducers) is not described in detail in this manual. Please refer to the documentation provided with each transducer.

Related topics Transducers, page 20 Additional required items, page 26

Depth rated transducers Sometimes collecting data from a vessel simply does not do the job for you. Perhaps you need to place the transducer in deeper waters closer to the target for better resolution.

You must then use a transducer that can handle the increased water pressure.

850-164696/B 23

If it is necessary to place the transducer in deeper waters, you can use a towed body. You can also place the transducer on the seabed for long term collection of data. We have for many years designed and built transducers for deep water applications like this. Our series of 7° depth rated transducers have standard depth rating to 1500 meters. We can also build transducers for greater depths.

For more information about the depth rated transducers provided, consult the Simrad website.

• http://www.simrad.com

The following depth rated transducers are recommended for the Simrad EK60 Scientific Echo Sounder. Note that all these are also split beam transducers. Standard depth rating is 1500 meters. If you need to work on larger depths, feel free to contact us for advice.

Related topics Transducers, page 20 Additional required items, page 26

Physical dimensions versus beam opening The physical dimensions of a transducer can be explained as a function of the beam opening at a given operating frequency.

Traditionally, a 7° opening angle has been the standard for marine surveys. However, for applications where the physical size and weight of the transducer is important, you can reduce the size by allowing a larger opening angle of the acoustic beam.

24 850-164696/B

The effective circular area of the transducer face is calculated from the equation:

=A l 2b

( )2 x p

Where:

• A =effective transducer circular area

• λ =wave length

• ß =beam width in radians (-3 dB points)

The transducer near field is the region right in front of the transducer face, where the sound waves are complicated and does not fall off spherically with range. Targets within the near field will not be detected correctly. The near field is calculated by the equation:

=Near field l A

Parameters from typical scientific transducers are given in the table. The maximum and minimum source level (SL) is calculated from the available power settings on the Simrad EK80 scientific echo sounder.

General safety rules The following safety precautions must be followed at all times during installation and maintenance work.

WARNING

The Simrad EK60 operates on 230 Vac 50/60 Hz. This voltage is lethal!

• You must always switch off all power before installation or maintenance work on the EK60 system.

Use the main circuit breaker, and label the breaker with a warning sign that informs others that maintenance or installation work is in progress on the system.

• For safety reasons, two persons must always be present during troubleshooting with power ON.

• Read and understand the applicable first aid instructions related to electric shock.

• Whenever maintenance is in progress, it is essential that a first aid kit is available, and that all personnel are familiar with the first aid instructions for electrical shock.

Supply power requirements Observe the general requirements related to the supply power.

The supply voltage to the equipment is to be kept within ±10% of the installation’s nominal voltage. Maximum transient voltage variations on the main switchboard’s bus-bars are not to exceed -15% to +20% of the nominal voltage (except under fault conditions).

Uninterrupted Power Supply (UPS) requirements Observe these requirements related to an Uninterrupted Power Supply (UPS).

We recommend that the EK60 system is powered using an Uninterrupted Power Supply (UPS) with sine wave output.

The Uninterrupted Power Supply must have the capacity to independently maintain power to the system for a minimum of 10 minutes. This ensures that the EK60 can be switched off in a controlled manner in the event of a power failure.

Basic wiring requirements Correct wiring is crucial for the operational performance of the EK60.

All cables running between system cabinets located in different rooms and/or on different decks must be supported and protected along their entire lengths using conduits and/or cable trays. Note that the cables must not be installed in the vicinity of high-power supplies and cables, antenna cables or other possible sources of interference.

All transducer cables must be run in steel conduits.

30 850-164696/B

For more detailed information about cables and wiring, refer to the basic cable requirements.

Compass deviation requirements EK60 system units that are installed on the bridge may have an effect on the compass.

Once the installation is complete, the vessel must be swung with the EK60 system in both operative and inoperative modes. The shipowner and captain are responsible for updating the compass deviation table accordingly with regard to the vessel’s national registry and corresponding maritime authority.

Noise sources The operational performance of all hydroacoustic systems depend on the noise conditions.

The vessel’s hull, rudder(s) and propeller(s) must be thoroughly inspected in dry dock prior to installation.

Roughness below the water-line deformities in the shell plating and protruding obstacles can create underwater noise. These sources of turbulence must be smoothed or removed as best as possible. It is especially important that the propeller(s) are not pitted or damaged.

Dry docking requirements Whenever devices for hydroacoustic use are mounted under the vessel’s hull, special considerations must be made prior to dry docking.

Make sure that ample clearance under the transducer(s) and/or protection blister is provided when dry docking the vessel.

Avoid locating supporting blocks or structures in the vicinity of this equipment.

Prior to dry docking, power down all hydro-acoustic systems on the vessel, and label each system accordingly to prevent anyone from powering up the system(s) accidentally.

Remove circuit breakers if necessary.

Classification approval requirements Classification approval is required for the EK60 installation.

The EK60 transducer installation must be approved by Det Norske Veritas (DNV) or another national classification society.

The shipowner and shipyard performing the installation are responsible for obtaining this installation approval.

850-164696/B 31

Network security If a EK60 system is connected to the ship’s local area network, data security is of vital importance.

Equipment manufactured by Kongsberg Maritime are frequently connected to the ship's local area network (LAN). Connecting any computer to a network will always expose the data on that computer to all other computers connected to the same network. Several threats may immediately occur:

• Remote computers can read the data.

• Remote computers can change the data.

• Remote computers can change the behaviour of the computer, for example by installing unwanted software.

Usually, two parameters are used to define the threat level:

1 The likelihood that any remote connection will do any of the above.

2 The damage done if a remote connection succeeds doing this.

Because Kongsberg Maritime has no information regarding the complete system installation on any vessel, we can not estimate the threat level and the need for network security. For this reason, we can not accept responsibility for network security. Systems provided by Kongsberg Maritime are regarded as stand-alone offline systems, even though they may be connected to a network for sensor interfaces and/or data distribution.

Note

No network safety applications are installed on any Kongsberg Maritime computers.

The computers are thus not protected against viruses, malware or unintentional access from external users.

Securing the EK60 system itself has no meaning unless there is a policy in place that secures all computers in the network. This policy must include physical access by trained and trusted users. The customer/end user of the EK60 system will always be in charge of defining and implementing a security policy, and providing the relevant network security applications.

Note

Kongsberg Maritime will not accept any responsibility for errors and/or damages caused by unauthorized use or access to the EK60.

Where to install the transducer

Topics Introduction, page 38

Mount the transducer deep, page 38

Avoid protruding objects, page 39

Stay far away from the propellers, page 39

Choose a position far away from the bow thruster(s), page 39

Summary and general recommendations, page 40

Introduction A single answer to the question “where to install the transducer” cannot be given.

The physical location of the transducer depends on the vessel's design and construction, how the hull is shaped, and how the water runs along the hull. There are however a number of important guidelines, and some of these are even conflicting.

Note

The information here must be considered as general advice. Each EK60 installation must be handled separately depending on the hull design.
