INTRODUCTION

SeaBat 7125 SV2 Operator’s Manual Page 1 June 1, 2012

1 INTRODUCTION

1.1 System Overview

The SeaBat 7125 SV2 (for Surface Vessel) is a high-resolution multibeam sonar system that measures relative water depths over a 140°1 (or 165°) wide swath perpendicular to the vessel's track.

The SeaBat 7125 SV2 is a dual-frequency system designed for convenient installation on small surface vessels. The dual-frequency system provides high-resolution functionality with the 400kHz frequency and long-range functionality with the 200kHz frequency.

SeaBat 7125 SV2 Operator’s Manual Page 2 June 1, 2012

1.2 System Architecture

The SeaBat 7125 SV2 multibeam sonar system consists of a combined sonar interface and processing unit, known as the transceiver, as well as a receiver unit and a projector unit, both with dual-frequency operation. 25 meter cables connect the receiver and projector units to the transceiver. User displays and system control originate within the transceiver.

For details on the various system components, see Appendix C Installation Instructions.

1.3 System Operation

The projector unit of the sonar head assembly transmits a pulse of acoustic energy, which travels through the water and is reflected by the seafloor or any objects in its path.

The reflected signal is received by the receiver unit of the sonar head assembly, digitized by internal electronics, and sent to the topside transceiver for beamforming and

2 It is possible to connect four monitors to the transceiver.

SeaBat 7125 SV2 Operator’s Manual Page 3 June 1, 2012 processing. The transceiver generates the video displayed on the monitor and formats a digital output to be used by a peripheral bathymetric data processing system (or the optional PDS2000 DAC preinstalled on the transceiver) while functioning as the control interface between the operator and the sonar system.

1.4 System Features

The main features of the SeaBat 7125 SV2 system are summarized below. Depending on the feature package purchased3, all features may not be available (see appendix F.2 Feature Packages).

Resolution: Dynamic, focused beamforming maintains ultra-high resolution, even at short ranges. A receiver sample rate of 34kHz provides unprecedented range resolution and complements the narrow beam, thus providing the user with ultimate data quality and resolution.

Fast update: The entire 140° (or 165°) swath is illuminated with a single transmission at an update rate of up to 50Hz (range selection dependent), maintaining 100% bottom coverage, even at high speed.

Depth rating: The SeaBat 7125 SV2 is depth-rated to 50 meters.

Data output: The SeaBat 7125 SV2 exports the standard hydrographic records of bathymetry, side-scan, and snippets as well as water column data and other data for more scientific applications.

Beamforming: The transceiver performs initial signal processing, a combination of time delay and phase rotation beamforming.

Bottom detection: The special bottom detection algorithm uses a combination of center-of-energy and phase-zero crossing algorithms to detect the bottom in each individual beam with the highest possible accuracy.

Uncertainty output: Uncertainty is computed for each sounding and presented graphically on various UI (user interface) displays.

Variable swath coverage: This feature gives the operator control of the swath coverage. It includes swath width settings ranging from 45º to 140º (or 165º) in increments of 5º as well as a choice of beam density mode.

Steerable swath: This feature allows swath to be steered electronically.

Head tilt: This feature makes it possible to operate with a physically rotated sonar head, which allows for very flexible and specialized applications of the SeaBat 7125 SV2.

XYZ offsets: This feature makes it possible to take into account offsets between the projector and receiver, when these two separate units are mounted remotely from each other. This way bathymetric accuracy is maintained.

3 Feature Packages include Standard and Efficiency.

Some features are not available with maintenance releases prior to FP2.

SeaBat 7125 SV2 Operator’s Manual Page 4 June 1, 2012

Auto pilot: This feature allows for automatic update of certain sonar settings.

When Autopilot mode is initiated, the SeaBat analyzes bottom detection data to determine the average bottom depth and maximum usable swath angle, then optimizes the sonar settings accordingly consistent with a user-configurable look-up table.

Operator selectable operating mode: The choice of five different beam modes allows the operator to select a beam mode appropriate to the application thereby optimizing sonar operation. Wide mode yields a swath of 165º, while the other four modes yield a swath of 140º. In addition, Flex mode provides settings for alternative beam distribution.

Beam distribution: The SeaBat 7125 SV2 offers the operator a choice between Minimum Beams (equiangular spacing), Intermediate, and Best Coverage (equidistant spacing) at both the 200kHz and 400kHz frequency. All options are dynamically focused.

On the fly frequency change: The SeaBat 7125 SV2 dual-frequency system may be operated at either frequency without the need to restart the 7k Center.

On the fly beam mode selection: Choice of beam mode (spacing and number of beams) can be done without restarting the 7k Center.

Real-time QC display: The SeaBat 7125 SV2 generates a real-time display with an intensity image on a high resolution 19-inch LCD monitor. Overlaid on this intensity image is the bottom detection display, giving the operator an excellent QC (quality control) tool.

Hardware sync pulse out: A TTL pulse (synchronous with the transmit pulse) is available from the transceiver.

1PPS pulse handling and time stamping: Data time stamping is referenced to an incoming 1PPS and associated time message.

External trigger: The system may be triggered using a standard 7k Center software remote command or by a TTL incoming trigger pulse.

Adaptive gating: Three different gate settings are available for application to the bottom detection process: No Gates, Absolute Gates, and Adaptive Gates.

Beam data recording: The SeaBat 7125 SV2 is capable of producing a stream of beam data that is operator configurable and may be written to either the transceiver local hard drive or an optional external RAID hard disk array.

Data logging software controls recording, playback, and data storage functions.

Built-In Test Environment (BITE): BITE is an integral part of the transceiver, monitoring the status of internal subsystems and the wet-end units.

SAFETY PRECAUTIONS

SeaBat 7125 SV2 Operator’s Manual Page 6 June 1, 2012

2 SAFETY PRECAUTIONS

If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

RESON assumes no liability if this product is operated in an unsafe manner.

2.1 Operator Safety

The SeaBat™ system should be handled with attention to operator safety as well as protection of the hardware components. General precautions include:

DO NOT connect or disconnect cables with the power on.

DO NOT attempt to open and service the projector or receiver units.

DO NOT attempt to open and service the transceiver without specific instructions from RESON.

DO NOT operate the system while divers are in the water and closer than two meters from the projector and receiver units. High-powered ultrasonic energy can be hazardous to human physiology.

For safety reasons the SeaBat™ must be connected to protective earth. The protective earth pin in the mains appliance inlet is the protective conductor terminal of SeaBat™.

This icon on any of the SeaBat components implies hazardous voltage on output connection.

2.2 Equipment Safety

Each SeaBat™ component is sufficiently robust for shipboard storage while in its own transit case or shipping box, which include handles and tie-down rings. Use appropriate discretion in lifting these components, as the cases may be awkward and heavy.

2.2.1 Safe Handling

To ensure safe handling of the equipment:

Inspect each transit case or shipping box for physical damage prior to opening, and each component for physical damage before installation.

Use original shipping boxes to provide adequate packaging and shock absorption when shipping or storing the equipment.

SeaBat 7125 SV2 Operator’s Manual Page 7 June 1, 2012

Do not drop the equipment.

Do not connect or disconnect cables at the rear of the transceiver or from the sonar head assembly while the transceiver is running. This can damage the internal workings.

Do not bend cables beyond the recommended limits.

Do not place the sonar head in an area where the face may be scratched or damaged. If an array must be placed on the ground, it should be placed on a flat surface and covered with a protective padded sheet.

Do not place liquids on or near the equipment.

Ensure that the equipment is properly secured before putting out to sea.

When the sonar head is in air and switched on, the transmit power should be switched off except when performing system checks, where power should be increased to a level which is audible for a short time only on a slow repetition rate (follow instructions in appendix C.7 System Check). A higher setting may damage the transmit array ceramics. The system should only be operated in air for very short periods of time.

Do not exceed operating and storage temperature limits.

CAUTION

Do not operate transmitters in air except during system checks for short durations.

2.2.2 Cleaning and Maintenance

2.2.2.1 Projector and Receiver

The acoustic window molded over the front of the projector and receiver arrays is made of high-density polyurethane. A long range of chemicals will destroy the polyurethane, which include, but are not limited to:

Acids

Automotive brake fluid

Base

Grease

Halogenated hydrocarbons (carbon tetrachloride, trichloroethylene)

Hydraulic fluids

Ketenes (MEK, acetone)

Nitro hydrocarbons (nitrobenzene, aniline)

Oil

Ozone

Petrol

Phosphate ester

SeaBat 7125 SV2 Operator’s Manual Page 8 June 1, 2012

The following recommendations are made to protect the arrays while in use and in storage.

For cleaning, use a mild, nonabrasive soap, fresh lukewarm water, and a soft brush.

Rinse the sonar with fresh water after every use.

Do not clean the array or sonar by using hot or cold pressure washers. The high-velocity water spray will cut through the polyurethane or damage the interface between the polyurethane and the sonar metal housing.

To scrape away marine growth from the arrays, use only a wooden tool.

Do not apply any antifouling paint on the acoustic window unless the type is recommended by RESON. The antifouling paint will affect the acoustic performance. RESON recommends:

o For high-frequency transducers (>100kHz) use International VC 17m.

o For low-frequency transducers (<100kHz) use SigmaGlide.

NOTE

As these products are subject to technical modifications, it is recommended that the most up to date PDS4 and MSDS5 are acquired prior to commencing the coating work.

SeaBat 7125 SV2 Operator’s Manual Page 10 June 1, 2012

2.3 Corrosion Avoidance

It is important that your SeaBat™ system be properly protected from the corrosive effects of the water in which the sonar head is submerged.

Aluminum components of your SeaBat system are not suitable for permanent installations on surface vessels. Aluminum components require regular cleaning with fresh water and sacrificial anodes must be inspected/renewed on a regular basis.

All aluminum housings are provided with zinc alloy sacrificial anodes to protect against galvanic corrosion while immersed in sea water, or with magnesium anodes for use in fresh water.

Take the following precautions to ensure the best usage of your SeaBat system’s sacrificial anodes.

Maintain electrical isolation between the sonar head and the mounting structure.

Do not paint the anodes.

Inspect the anodes periodically for cleanliness and good physical condition.

Tighten or replace loose anodes immediately.

WARNING!

Sacrificial anodes, when new, have a thin coating to prevent them from oxidizing. The first time the anodes come in contact with water the coating will dissolve thereby making the anodes active. If the anodes are removed from the water, even for a short period of time, they will oxidize (in a matter of minutes) forming a layer that must be removed before the anodes and sonar head are placed in the water again.

2.4 Electrical Isolation

Electrical isolation for both titanium and aluminum components may be achieved by using nonconductive bushings, washers, and isolation plates to insulate them from the mounting brackets. Common nonconductive materials include Delrin, G-10/FR4 glass fiber sheets, and high-density polyethylene sheets.

If the sonar head is not isolated from the mounting structure, galvanic corrosion will result in either the housing (aluminum housings) or in the mounting structure itself (titanium housings).

Additionally, an undue amount of stress will be put on the affected sacrificial anodes, causing them to be used very quickly.

Contact RESON for additional information on schemes for electrical isolation.

SeaBat 7125 SV2 Operator’s Manual Page 11 June 1, 2012

2.5 Exposure to Sunlight

Do not allow the projector and receiver arrays to sit in direct sunlight when not in use, but cover the arrays with a bag. In addition to furthering corrosive effects, continued exposure to ultraviolet (UV) rays will damage the polyurethane array face.

2.6 Safe Disposal of Waste (WEEE Directive)

4.2 Configuration Menu Options

The various configuration options available for the SeaBat 7125 SV2 sonar system are shown in the following illustration and are described in detail in the subsections below.

4.2.1 Data Display & Format

The Data Display & Format dialog controls the type of 7k records that are generated and displayed. These selections also determine what data is displayed.

SeaBat 7125 SV2 Operator’s Manual Page 19 June 1, 2012

Water Column Data: Use the radio buttons to select either amplitude only or full beam data for display in the A-scan window to the left of the sonar wedge and for output over the Ethernet broadcast or storage to a Windows file.

o Signal Analysis Mode: Magnitude and phase data are both transmitted to the user interface. This allows for phase data to be analyzed in the A-scan displays. As this option increases the CPU usage for the SeaBat, RESON recommends that this option only be used when inspecting phase data.

o Operator Mode: The SeaBat extracts only the magnitude from the ping data. This data is then compressed to a maximum of 1024 samples. If less than 1024 samples are received in the ping, no compression occurs. This feature improves the performance of the system, but eliminates the ability to inspect the phase data.

General QC Displays: Select additional displays:

o Sidescan: Select the check box to display the Side Scan tab.

Snippets Control: Select the check box to display the Snippets tab.

o Sample Window Maximum: Not available.

4.2.3 Hardware Configuration

The Hardware Configuration dialog controls the one-time transmit array and projector settings. These settings should be set to reflect the initial installation of your system and should not require modification unless the physical installation changes. For details on sonar head installation, see appendix C.6.4 Sonar Head Assembly Orientation.

4.2.3.1 Configuration

Standard SV2 Mounting Bracket:

PN 85160026 (see also appendix E.3 Mounting Bracket):

Preset Configurations:

o Normal: When the receiver is mounted with the connector to the port side, the Configuration selection should be SV2 Bracket (see appendix C.6.4 Sonar Head Assembly Orientation).

SeaBat 7125 SV2 Operator’s Manual Page 26 June 1, 2012 o Reversed: When the receiver is mounted with the connector to the starboard side, the Configuration selection should be Reversed SV2 Bracket (see appendix C.6.4 Sonar Head Assembly Orientation). Note that this normalizes the image only and does not affect data output.

Customer Configuration:

o For nonstandard installations, the XYZ offset of the projector reference point from the receiver reference point must be defined. For details on reference points, see appendix C.6.5 Sonar Reference Point, and Figure 79: Sonar Reference Point Definition, sheet 3.

Incorrect offset settings could severely affect data quality.

4.2.3.2 Head Tilt7

The Head tilt feature allows the user to normalize the display, gates, and bottom detect processing to reflect the physical orientation of the sonar head. Users often tilt head to increase coverage to one side, particularly when surveying harbor walls or other vertical structures.

The angular value is entered in degrees (+ port up/- port down) and must be between - 45° and 45° in increments of 0.5°.

EA beams (Minimum Beams mode) are recommended when using head tilt, as ED beams (Best Coverage mode) are still formed assuming a horizontal seafloor.

For examples on how to use this feature, see section 6.3.3 Head Tilt.

7 Available with the Efficiency feature package (see Table 19).

Not available with maintenance releases prior to FP2.

SeaBat 7125 SV2 Operator’s Manual Page 27 June 1, 2012

4.2.4 Advanced Ping Settings

The Advanced Ping Settings dialog is not configurable. Default settings are Continuous Wave (CW) and Single Ping.

4.2.5 Triggering

The Trigger/PPS Configuration dialog allows the operator to control the pulse length and delay characteristics.

SeaBat 7125 SV2 Operator’s Manual Page 28 June 1, 2012

4.2.5.1 Trigger Input

Active: The Active check box is not selected (inactive) by default. When selected, the ping will occur upon receipt of the input trigger pulse. If the trigger pulse rate exceeds the sonar’s actual maximum ping rate for that range setting, some trigger input pulses may be dropped. Deselecting the check box will return the sonar to ping at the rate dictated by the settings on the Main Sonar Settings tab.

4.2.5.2 Trigger Output

A TTL trigger out pulse, approximately synchronous with the transmit pulse, is available via a BNC connector marked Trig Out on the rear panel of the transceiver (see appendix C.3.3 Transceiver Cable Connections). Figure 4 shows a pulse example.

Figure 4: Example of Trigger Output: Delay = 0, Pulse Width = 1

Active: The Active check box is selected by default. When selected, a pulse will be generated in conjunction with the sonar ping.

Delay: The default setting is 0.00ms. This setting allows the operator to specify how many milliseconds after the sonar ping the output pulse will be sent.

Pulse Length: The default setting is 1.00ms. This setting allows the operator to change the pulse length of the transmitted output signal. For the SeaBat 7125 SV, the pulse length plus the delay must be slightly less than 20ms.

Apply: Click the Apply button to finalize changes.

4.2.5.3 1PPS Polarity

Rising edge: By default, the SeaBat system accepts positively polarized (rising edge) 1PPS pulses to perform accurate time stamping.

SeaBat 7125 SV2 Operator’s Manual Page 29 June 1, 2012

Falling edge: If a negatively polarized (falling edge) 1PPS is used, the Falling edge button in the Trigger/PPS Configuration dialog must be selected to ensure accurate timing.

The 1PPS selection will appear on the sonar image control portion of the Primary Display tab (see also section 5.3.4 1PPS Input Indicator).
