19 -- TOWED BIOASSAYER SYSTEM SOL N62306-98-R-A003 DUE 062698 POC Contract Specialist, N.F. HAIRSTON, (228) 689-8367, M. M. Fletcher, Contracting Officer, (228) 689-8369 The Naval Oceanographic Office is seeking information concerning potential sources, including manufacturers, dealers and/or distributors of currently available commercial off the shelf Towed Bioassayer Systems for undersea operations. Minimum Government requirements for the System are as follws: The System shall consist of a high resolution echo sounder providing real-time volume backscattering strength and single-fish target strength measurements at three frequencies simultaneously whose transducers are mounted in a towbody. The system must be capable of displaying and storing target strength distribution and single-fish target strength distribution electronically to a Government-owned UNIX workstation for examination or processing; acquire, analyze and display three channels of acoustic data simultaneously or any combination of three from transducer/ transceiver sets. For each channel the system will accommodate: volume backscattering strength and single-fish target strength, water column layers, sub-bottom profiling, sound speed profiles, statistical calculations, hard copy output of statistical data, echo integration, bottom detection and noise level detection. System is to be manually operated using interactive, nested, on- screen menus, provide four modes of operation (passive, active, external trigger and test). System shall: provide real-time or color hard copy outputs for each channel, operate 24 hours a day for up to 32 days w/o preventive maintenance or refurbishment; consist of separate shipboard suite and towbody. Sub-system operation: 110-130 VAC, 50/60 HZ, NTE 400 W; function in 10% -- 90% non-reducing relative humidity in a temperature range of 10 deg to 40 deg C; withstand shipboard vibration in moderate to high seas; be rack-mountable in single 19" rack NTE 60" in height, total weight NTE 100 kg. Towbody: designed for data acquisition speeds of 6-8 kts and transiting and maneuvering speeds of 10-12 kts; withstand deployment and retrieval using a winch and U-frame; does not undergo excessive roll pitch and heave at data collection speeds in sea states from 0-4; accommodate up to three downward facing transducers in any combination with balancing system for using one or two; not exceed four meters in length, one meter in diameter, or 400 kg weight fully laden. Written responses are required and should include contractor name, address, phone number, fax number, point of contact, e-mail address, if applicable. Commercial vendors who intend to respond to this notice are to provide at a minimu, two (2) complete sets of brochurs/descriptive literature and price list(s) applicable.
