20 -- DOPPLER SONAR VELOCITY LOG (DSVL) SOL N00024-99-R-4052 POC Chris Hannah, SEA 024, Contract Specialist, (703) 602-0200 DOPPLER SONAR VELOCITY LOG (DSVL) SPEED SENSOR, SOLICITATION N00024-99-R-4052. The Naval Sea Systems Command (NAVSEA) is conducting a market survey to identify any alternate source manufacturers, in addition to the presently qualified manufacturer -- Sperry Marine, Inc. for a DSVL. Our intent is to procure and qualify for competition a modified Commercial Off-the-Shelf (COTS) system or Non-Developmental Item (NDI) to satisfy the requirements defined in SHIPS-D-6000 (Prime Item Product Function Specification for the AN/WQN-2 Doppler Sonar Velocity Log). Specific requirements which must be satisfied include those concerning transducer dimensions, accuracy, and operating frequency. The DSVL is planned for installation on both submarines and surface ships to replace the present Electromagnetic Log (EMLOG) system. It is planned to award the successful offeror a contract to provide a minimum of two systems with at least one set of spares. These systems will be utilized to verify that the manufacturer's design and fabrication is in compliance with SHIPS-D-6000 through laboratory/simulation qualification/performance/environmental and at-sea testing. The contractor will be required to perform qualification testing and support the Government Development Test (DT)/Operational Test (OT) program which must be completed by December 2000. We then plan to issue a competitive RFP for a base year with two option years with an estimated total of at least 30 systems per year, depending on the funding received. Follow-on competitive contracts will continue the fleet's conversion to DSVL, currently estimated to be 217 systems to supplement the above effort (90 systems) and those systems delivered under a Sperry Marine, Inc. sole source contract. Companies sufficiently advanced in DSVL technology so as to be capable of meeting the timeframe requirements and interested in receiving a copy of the unclassified performance specification should submit their request in writing; separate arrangements will be established for review of classified information. Responses should be received at the Naval Sea Systems Command, Attention: Chris Hannah, SEA 02423H by 15 December 1998. Posted 11/30/98 (W-SN275436). (0334)
