- Description
- THIS SYNOPSIS/SOLICITATION IS AMENDED TO DELETE THE SMALL BUSINESS SET-ASIDE. THE CLOSING DATE IS REVISED TO 4:00 P.M. DECEMBER 22, 2006. THIS IS A COMBINED SYNOPSIS/SOLICITATION FOR COMMERCIAL ITEMS PREPARED IN ACCORDANCE WITH THE FORMAT IN FAR SUBPART 12.6, AS SUPPLEMENTED WITH ADDITIONAL INFORMATION INCLUDED IN THIS NOTICE. THIS ANNOUNCEMENT CONSTITUTES THE ONLY SOLICITATION; QUOTES ARE BEING REQUESTED AND A WRITTEN SOLICITATION WILL NOT BE ISSUED. The Request for Quotation (RFQ) number is EA1330-07-RQ-0074. The U.S. Dept. of Commerce, Mission Support Division, Norfolk, Virginia has a requirement to purchase the following equipment: (1) 25,854 ft. of Electromechanical Cable in accordance with the following specifications: NOAA Electromechanical Cable Requirements Introduction: The Office of Marine and Aviation Operations Center, Atlantic and Pacific, uses electromechanical cable to lower various scientific instruments over the side of their oceangoing research vessels. The cables support the instruments and provide the means for electrical signals to pass between the instruments and the vessel. It is typically called "CTD wire". The following specifications describe in general terms the significant characteristics the cable design must have. No priority is implied by the order given. General: An electromechanical cable is required to lower various scientific instruments over the side of an oceangoing research vessel. The cable shall be capable of safely lowering an instrument to 6,000?m water depth in the dynamic environment caused by ship and wave motion, and lowering/raising speeds of 70 m/min. Multiple conductors are required for the real time transmission of electrical data and control signals and for redundancy. The cable shall be capable of being stored under tension for long periods of time on single drum winches to multiple layers. Resistance to crushing is desirable. It is expected that payloads will frequently produce loading of the cable (both static + dynamic) approaching 50% of rated breaking strength (RBS). The cable will be used with LEBUS grooved drum shell. The cable must be compatible with existing LEBUS grooved shells for a Markey DESH-5, 38" width drum. As listed below: Winch (Manufacturer) Model No. Drum Width Pitch Number of Grooves Markey DESH-5 38? 0.329004 115.5 38? 0.3 116.5 38? 0.323404 117.5 38? 0.3 118.5 24? 24? DESH-3 24? 73.5 24? 74 COM-7 DUSH-3 After manufacture of the cable, a piece, approximately 30 meters in length will be sent by the manufacturer to Markey for determination of what Lebus will be necessary for the cable to be used on the Markey winches above. The report from Markey detailing the recommended Lebus for the Markey winches showing the airgap for various pitch Lebuses and the loading/stretch data used to determine the airgap will be provided to the purchaser before the cable is shipped. This report shall no more than $500 to the price of the cable. Characteristics: 1) Maximum strength attainable -- identified as the best possible ratio of strength to weight. The ability of a cable to "survive" under extreme conditions is a function of its Rated or Ultimate Breaking Strain. 2) Highest elastic limit attainable -- identified as the best possible ratio of elastic limit to weight. This characteristic controls the mix of payload size, wire out, wire speed and environmental conditions at which the cable can operate with safety. This applies to both strength and electrical components of the cable. 3) High rotational stability -- identified as a minimal amount of axial rotation under loads cyclically varying from 0% to 45% of RBS. Low rotation is considered necessary to avoid looping/hockling the cable on bottom contact or "Zero" tension conditions and to prevent excessive spinning of lowered instruments. (A 'trade off' with item 15) 4) High degree of armor stress balance -- identified as the absence or near absence of variations to the relative loading on inner and outer armors that produce strength degradation when one end of the cable is free to rotate. 5) Minimum service life of 5 years -- the useful life in "normal" service assuming reasonable care and proper handling. 6) Cable shall be capable of operating at: >30% RBS for 90% of expected life. >40% RBS for 70% of expected life. 7) The cable shall be able to withstand occasional loading to 50% RBS without significant reduction in strength or change in electrical characteristics. 8) The armor shall be galvanized. 9) The cable shall have a finished O.D. of 8.1788 mm (0.322"). 10) The cable shall be in two unbroken lengths of 7,800 m (without splices). 11) The cable shall be capable of operation with single drum winch systems where the cable is stored under tension. 12) The cable shall be able to operate continuously (useful life) over sheaves not less than (NLT) 40 times the cable diameter without degradation in strength. 13) The cable must be capable of withstanding repeated flexures over sheaves at the nominal working loads given in item 6 without degradation in strength or change in electrical characteristics. 14) The cable shall be capable of withstanding cyclical loading in tension as results from ship motion without degradation in strength or change in electrical characteristics. 15) The cable shall exhibit the best possible resistance to abrasion, both internal and external, consistent with the need for high rotational stability. (A 'trade off' with Item 3) 16) The cable shall exhibit the best possible resistance to corrosion, particularly crevice corrosion and hydrogen imbrittlement. 17) The cable shall not unlay when cut, i.e. it must be well preformed. 18) The cable shall be lubricated for abrasion and corrosion protection. The lubricant should not extrude in use and be of non-petroleum base. 19) The cable shall have multiple electrical conductors capable of efficient transmission of low power signals at frequencies < 20 kHz. Cable design should be optimized to permit simultaneous transmission of 5 kHz and 10 kHz signals in a single conductor to armor circuit. Performance Specifications: 1) Finished Diameter: - The finished diameter shall be 8.1788 mm (0.322") at a loading of 15% of RBS. The diameter shall be uniform over the length of the cable with tolerances of (?0.0508 mm (0.002") and +0.076 mm (0.003")). 2) Working Diameter: - The change in cable diameter due to a change in cable loading shall not exceed 2% of the finish diameter. At a loading of 50% RBS the cable diameter shall not be less than 8.03 mm (0.316)". 3) Rotation: - The finished cable should not rotate about its axis more than 65 degrees per meter at 40% of RBS. It is recognized that this requirement may not be met given the specified outer armor wire size and minimum sheave diameter. 4) Rated Breaking Strength: - > 4500 Kg (10000 lbs) with one end free to rotate. 5) Flexure Tolerance: - Withstand > 50,000 flexure cycles over sheaves 40 times wire O.D. at 35-40% of RBS without failure of individual wires or degradation of electrical performance.
