Dual Head Ultra-High Resolution Broadband Multibeam Echosounder System

US Army Corps of Engineers San Francisco District (USACE SPN), San Francisco, CA

Part 1

PROJECT INFORMATION

1.1 Description of Requirement: The Contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items and non-personal services necessary to provide a Dual Head Ultra-High Resolution Broadband Multibeam Echo Sounder system for USACE

SPN in Sausalito, CA.

1.2 Place of Performance: The manufacturing of multibeam system shall be at manufacturer’s plant and delivered to Sausalito, California.

1.3 Scope: The scope of this requirement is to provide a Dual Head Ultra-High Resolution

Broadband Multibeam Echosounder system. The system shall meet the following requirements:

1.3.1 Dual Head Ultra-High Resolution Broadband Multibeam Echo Sounder:

Sonar Heads & Mounting Brackets: The system will have two sonar heads with the capability of being reconfigured to operate with only one sonar head. The system shall have two sonar head mounting brackets, one for using two sonar heads and one for operating with one sonar head.

Input Voltage: The system voltage input shall be 100-230VAV 50/60Hz.

Wet-end Cable: The system transducer/receiver cable lengths shall be 10 meters.

System Head Weight: The system head weight shall not exceed 16 kg.

Transmitting Frequency: The system shall have the capability of user selected frequencies between 200 kHz and 400 kHz in 10 kHz intervals.

Across Track Beam Width: The system shall have across track beam width of no more than 0.5 degree at 400 kHz and 1 degree at 200 kHz.

Along Track Beam Width: The system shall have along track beam width of no more than 1 degree at 400 kHz and no more than 2 degree at 200 kHz.

Number of Beams: The system shall have user selectable beams between 20 and 1024.

Swath Coverage: The system shall have a max swath coverage of at least 220 degrees.

Typical Depth: The system shall have a typical depth of 0.5-180 meters @ 400 kHz and 0.5- 375 meters @ 200 kHz.

Max Depth: The system shall have a max depth of 300 meters @ 400 kHz and 575 meters @ 200 kHz.

Ping Rate (Range Dependent): The system shall have a user selectable ping rate of up to 50 pings per second.

Pulse Length: The system shall have user selectable pulse lengths of 15µsec to 10 msec.

Gates: The system shall have fixed depth and adaptive gates for noise reduction.

Swath Steering: The system shall have the ability to electronically steer swath up to 85 degrees port and starboard.

Tilt Head: The system software shall have the ability to adjust for tilt.

Depth Resolution: The system shall have at minimum 6mm or better depth resolution.

On The Fly Adjustments: The system shall have the ability to adjust all settings on the fly.

Continuous Wave & Frequency Modulation: The system shall be capable of operating in continuous wave or frequency modulation mode.

Hypack Integration: The system shall be capable of interfacing and be compatible with Hypack

2016 or newer for collection and processing data.

Independent Steerable High Density Swath Sector: The system shall have the ability to form an independent steerable high density swath sector within the full swath.

Outputs: The system shall output bathymetry, sidescan, snippets backscatter, full water column backscatter, compressed water column backscatter and normalized backscatter.

User Interface: The system shall be able to display bathymetry, sidescan and backscatter views simultaneously, and display real-time imagery during data collection, with adequate resolution and on-screen history to aid in search, location, identification and recovery applications.

Test Environment: The system shall have a build-in test environment.

Modular Configuration: The system shall have a modular configuration with separate serviceable projector, receiver, inertia unit, and processing units.

Quality Filters and Flags: The system shall employ quality filters and quality flags.

Inertia System: The system shall have inertia system integrated into the topside processing unit, with the sensors mounted at the sonar head(s). All cables provided. The inertia system shall have a roll/pitch accuracy of 0.01 degrees, heading accuracy of 0.010 degrees, heave accuracy of

5cm/5%, true heave accuracy of 2cm/2%. Inertia system data file outputs must be compatible with

POSPac version 8.0 or newer. Software license(s) and/or dongle key must be included.

Windows Compatible Computer: The system shall include a rack mountable windows compatible computer with Windows 10 Professional pre-installed, Intel I7 or comparable processor, 32 gigabytes of DDR RAM memory or better, and at least 1 terabyte solid state hard drive(s).
