SSECTION 1:

OVERVIEW

The EdgeTech 4125 Series Dual-frequency Side Scan Sonar System is a frequency-modulated (FM), dual-frequency, side scan sonar that uses EdgeTech’s proprietary Full Spectrum “chirp” technology to generate high-resolution, side scan imagery at longer ranges than conventional continuous-wave (CW) systems. The system is designed primarily for search and recovery operations, along with surveys in shallow water. The 4125 Series is available in two, dual simultaneous frequency configurations depending on the application: 400/900 kHz and 600/1600 kHz. For shallow water survey applications, the 400/900-kHz frequency set is the best choice, as it provides an ideal combination of range and resolution. For ultra-high resolution imagery at shorter ranges, the 600/1600 kHz set is the recommended choice.

In both configurations, the frequencies are transmitted as linearly-swept, wide-band, high energy acoustic pulses, and the received echoes are processed into high signal-to-noise (SNR) images that can be directly displayed as shades of gray or color on a computer monitor. The SNR images can also be printed on a continuous feed thermal printer, or stored in real time onto a large capacity hard drive and archived onto a DVD.

1.1 4125 Series Applications

Applications for the 4125 Series Dual-frequency Side Scan Sonar System are many, including: x Hydrographic surveys

x Geological surveys x Search and recovery

x Channel conditioning/clearance surveys x Bridge, pier, and harbor wall inspections x Hull inspections

x Port security

(22)

Figure 1-1: Readying the Towfish for Deployment

1 1.2 Main System Components

The 4125 Series Dual-frequency Side Scan Sonar System is composed a 4125-P Portable Topside Processor, a 4125 Tow Vehicle (commonly called a Towfish), and a tow cable. These components are shown in Figure 1 2.

In addition, the tow vehicle is available with or without the additional telemetry option, which enables the use of longer tow cables. Without the additional telemetry option, tow cables up to 150 meters in length can be used. With the additional telemetry option, the system will perform with cable lengths up to 600 meters. Contact EdgeTech Customer Service for the specific cable types.

1.3 4125-P Portable Topside Processor

The 4125-P Portable Topside Processor is shown in Figure 1-2. It provides power and downlink telemetry to the tow vehicle for sonar control and receives uplink side scan data, sensor data, and status information from the tow vehicle for processing, storage, and display.

The topside unit includes a laptop computer with Windows 7 and the EdgeTech DISCOVER 4125 Side Scan Sonar software preinstalled. DISCOVER 4125 provides control, storage, and display of the sonar data. The data can be stored in XTF and JSF formats.

(23)

The 4125-P Portable Topside Processor interfaces with the tow vehicle either over a direct 10/100BaseT connection or, with the additional telemetry option, over a 10BaseT connection that uses very high bit rate digital subscriber line (VDSL) modems. The topside unit also interfaces with a global positioning system (GPS) over a USB to serial or RS-232 serial interface.

The topside processor integrates tow vehicle and DC power supplies, an ETHERNET switch, a wireless router, and, with the additional telemetry option, an VDSL modem, all housed within a single, compact, rugged, water-tight (when closed) Pelican Storm Case. It runs on either AC or DC power, and interfaces with the laptop computer over a wired or wireless 10/100BaseT ETHERNET connection. The computer can be stored inside the enclosure when not in use.

CAUTION!

Never attempt to use the portable topside’s storm case as a shipping container. Doing so could void warranties and/or result in system damage.

1 1.4 Tow Vehicle

The 4125 Tow Vehicle is available with a choice of 400/900 kHz or 600/1600 kHz operating frequencies, and with or without the additional telemetry option. It contains the sonar transducer arrays and the electronics required to transmit and receive the sonar signals; to receive the downlink commands from the topside processor; and to provide the uplink side scan data, sensor data, and status information to the topside processor.

The electronics are contained inside a single, lightweight stainless steel, 200-meter depth-rated housing, comprising the aft section of the tow vehicle. The forward section is flooded and includes both the port and starboard transducer arrays. A single O-ring sealed end cap is attached to each end of the housing to seal it, and the forward end cap contains bulkhead connectors for connecting to the transducer arrays. An adapter cable also connects to this end cap.

The cable snakes through a hole in the transducer array section and includes an inline connector for connecting to the tow cable. The tow vehicle interfaces with the topside processor either over a 10/100BaseT ETHERNET connection, or (with the additional telemetry option only) over a 10BaseT connection that uses VDSL modems in both the tow vehicle and the topside processor.

The tow vehicle is also equipped with four stabilizer fins, a stainless steel nose for hydrodynamic balance, and two convenient carrying handles. A towing arm is rigidly mounted to a tow point on the top of the tow vehicle housing adjacent to the tow cable connector. The tow cable attaches to a shackle on the towing arm.

Additional mounting holes are provided on the tow point should it be necessary to reposition the towing arm forward or aft to adjust the balance of the tow vehicle. The towing arm also includes a safety release

(24)

1-4

mechanism, which causes a shear pin to release the tow point should the tow vehicle hit an obstruction or become snagged. If this happens, the tow vehicle will rotate nose down, and a safety cable, which is attached from the tow point to the rear of the tow vehicle, will pull the tow vehicle over the obstruction or through the snag, stern first.

1 1.5 Tow Cable

The 4125 Series Dual-frequency Side Scan Sonar System includes a 50-meter tow cable, terminated at both ends. The tow cable is used both to connect to the tow vehicle, and to tow it behind the survey vessel. Tow cables are available as either a Kevlar-reinforced six conductor or an RG-58 coax cable, which includes a single conductor and a shield.

The coax cable is used only for systems that include the additional telemetry option. Up to 150 meters of 6 conductor cable or 600 meters of coax cable can be used. Contact EdgeTech Customer Service for available cable lengths other than the supplied 50-meter cable. A cable grip is also included for attaching the tow cable to a shackle on the towing arm of the tow vehicle.

1.6 Optional Equipment

Optional equipment that can be installed and used with a 4125 Series Dual-frequency Side Scan Sonar System includes:

x Additional telemetry (specified when ordering tow vehicle) x Keel Weight Kit (p/n 0008464)

x Depressor Wing Kit (p/n 0007860)

x HullScan Kit, W/O Telemetry (p/n 0008478) x HullScan Kit, W/ Telemetry (p/n 0008477) x Over the Side Mount (p/n 0007633)

1.6.1 Additional Telemetry

The additional telemetry option increases the maximum length tow cable that can be used from 150 meters to 600 meters by using VDSL modems to establish the communications link between the tow vehicle and the topside processor instead of a direct ETHERNET connection. Contact EdgeTech Customer Service for the specific cable types.

1.6.2 Depressor Wing

The Depressor Wing Kit provides a depressor wing (shown in Figure 1-3) that can be attached to the tow vehicle, allowing it to be towed deeper and faster without increasing the length of tow cable in the water. The depressor wing attaches to the top of the tow vehicle and pushes it deeper by exerting a downward force on the tow vehicle as it moves through the water. A safety cable with a shear pin mechanism is attached to prevent loss of the wing should it become snagged.

(27)

1.6.3 Keel Weight

The Keel Weight Kit provides an additional 15 lbs. of weight to the tow vehicle.

1.6.4 HullScan W/O and W/ Telemetry Kits

Two HullScan Kits are available, W/O Telemetry and W/ Telemetry. Each of these kits enables a tow vehicle to be inverted such that the transducer arrays are angled upward instead of downward. In this configuration the tow vehicle can be used to scan the hulls of ships. The HullScan W/O Telemetry kit is for tow vehicles that do not have the additional telemetry option. The HullScan W/ is for those that do.

1.6.5 Over the Side Option

This option allows the towfish to be mounted on a pole for shallow water survey or for vertical imaging. Contact EdgeTech Customer Service for more information.

The main hardware elements in the 4125-P Portable Topside Processor include the following components and circuit boards:

Power board. The Power board inputs +24 VDC on J2 from the 24 VDC Power Supply and

generates the 75 VDC tow vehicle power, which is output on J5 to the Power Separation board, and from this board to the tow vehicle.

The Power board also includes +5, +12, and +15 VDC power supplies. The +5 VDC is output on J3 to the Wireless Bridge/ETHERNET Switch board, and the +12 VDC is output on J6 and J8 to the VDSL Modem board and the fans, respectively. For DC operation, 12–24 VDC is input on J1.

VDSL Modem board. The VDSL Modem board, which is used only with the additional telemetry

option, converts the uplink data VDSL signals received from the tow vehicle and input on P4 from J3 of the Power Separation board into ETHERNET 10/100BaseT signals. These signals are then output on P2 to the Wireless Bridge/ETHERNET Switch board, and from J1 of this board to the laptop computer.

Similarly, the VDSL Modem board converts the downlink ETHERNET 10/100BaseT based command signals from the laptop computer into the VDSL downlink command signals, which are then output on P4 to J3 of the Power Separation board to be combined with 75 VDC tow vehicle power, and transmitted to the tow vehicle.

24 VDC Power Supply. The 24 VDC Power Supply inputs AC power from the AC Line Filter to

generate +24 VDC, which is output to the Power board.

AC Line Filter. The AC Line Filter filters the AC power input and outputs the filtered power to the

24 VDC Power Supply.

Wireless Bridge/ETHERNET Switch. The Wireless Bridge/ETHERNET Switch board connects the

VDSL Modem board, the tow vehicle, and the laptop computer to the same local area network (LAN). This board also enables a wireless connection to the laptop computer.

Power Separation board. With the additional telemetry option only, the Power Separation board

combines downlink command signals and uplink data that are input on J3 from P4 of the VDSL Modem board with 75 VDC tow vehicle power from J5 of the Power board for transmission to the tow vehicle.

If the additional telemetry option is not included, the Power Separation board is used only to route the 75 VDC tow vehicle power to the tow vehicle Commands and data are sent and received, respectively, over a direct ETHERNET connection to the tow vehicle.

SETUP AND ACTIVATION

Setup and test of the EdgeTech 4125 Series Dual-frequency Side Scan Sonar System encompasses unpacking, inspecting, and connecting the system components (including an optional printer); connecting a navigation system if required; activating the system; and verifying operation using the EdgeTech DISCOVER 4125 Side Scan Sonar software. This section provides instructions on how to perform these tasks, along with how to deploy, tow, and recover the tow vehicle.

3.1 Unpacking and Inspection

The tow vehicle is shipped in a foam-lined Pelican Storm Case. The 4125-P Portable Topside Processor is shipped in a cardboard box with its associated cables, including the tow cable, depending on its length. Before unpacking the system components, inspect the shipping containers for any damage. Report any damage to the carrier and to EdgeTech.

If the shipping containers appear free of damage, carefully unpack the components and inspect them for damage as well. Also check the packing list, verifying that all the items on the list are included. Again, if any damage is found, report it to the carrier and to EdgeTech. If any items are missing, immediately contact EdgeTech Customer Service. Do not install or operate any equipment that appears to be damaged. Although the items shipped will vary, depending on the customer requirements, the 4125 Series Dual-frequency Side Scan Sonar System typically includes the items listed below.

x 4125-P Portable Topside Processor x 4125 Tow Vehicle

x Laptop computer

x Laptop computer power supply x 50-meter tow cable

x AC power cable x DC power cable x ETHERNET cable x Software CDs x Spares kit

After unpacking the system components, store the shipping containers, including any packing materials, in a safe place for later use. When transporting or storing the system, pack all items in their original shipping containers in the same manner in which they were originally shipped. Store the system in a dry environment when not in use.

3.2 Power Requirements

The power requirements for the 4125-P Portable Topside Processor are 90–260 VAC, 50/60 Hz or 12–24 VDC.

(44)

3-2

3.2.1 Use of an Uninterrupted Power Supply

The AC power source should be continuously free of high-amplitude, high-frequency transients, as this type of interference could cause degraded performance or damage to the equipment. An uninterruptable power supply (UPS) with power surge protection is recommended for powering the equipment.

However, whether or not a UPS is used, never use an AC power source that also powers electric motors on the survey vessel, such as pumps and winches. In addition, do not use switching type battery chargers or DC to AC converters with square wave outputs.

3.2.2 Changing a Non-US Power Plug

An AC power cord is provided for connecting the Deck Unit to a standard U.S. 3-pronged outlet. For non-U.S. power outlets, modify this cord by cutting off the 3-pronged plug and attaching the appropriate plug. Refer to Table 3-1 for connection information.

3.3 Navigation Interface

The 4125 Series Dual-frequency Side Scan Sonar System accepts all standard National Marine Electronics Association (NEMA) 0183 message sentence formats from a connected global positioning system (GPS) or integrated navigation system.

3.4 Placement of the 4125-P Portable Topside Processor

The 4125-P Portable Topside Processor can be located in a wet environment if the cover is kept closed. Otherwise it should be located and set up in a dry, sheltered area that is protected from weather and water spray, and where the temperature is consistently between 0°C and 40°C (32°F and 104°F). However, avoid areas of direct sunlight, especially in tropical environments, as heat build-up could occur.

(45)

The location should also enable direct communications with the deck crew that is handling the tow vehicle. Secure the topside processor in place, using tie downs if necessary, near the required AC power source.

3 3.5 Topside Controls and Indicators

The 4125-P Portable Topside Processor includes controls and indicators on the side panel as shown in
