OBJECTIVE: Develop a new threshold velocity detector that identifies two or more distinct velocities, uses little to no power, and reduces corrosion potential compared to the legacy device.
DESCRIPTION: The current threshold velocity detector system is manufactured primarily from aluminum and a custom rubber to allow for operation. This system experiences corrosion due to the direct interface with a sea-water environment and the mechanical design. This incurs a significant rework and life cycle cost. Some areas for improvement for the current system that could increase the performance and maintainability include:
Prototypes will be tested by the contractor and the Navy to meet the requirements of the detector and the program safety requirements.
Replacement of the current inventory of the legacy detectors will also be considered as the program is expected to remain in-service for at least 30 more years. This system could also be used to increase the information in future systems fed into the program and allow for better understanding of the current designs. This will provide opportunities for a lower cost design/simpler design that will relate to a smaller failure pool at the maintenance facilities and reduced downtime for current assets. Preventing corrosion will reduce the costs associated with rework and repairs during these maintenance actions.
The current leading technologies in the velocity detector industry include Coriolis, Differential Pressure, Magnetic, Multiphase, Turbine, Ultrasonic, and Flow velocity detectors. As this situation would support sea-water applications, gas measuring devices such as Vortex and differential pressure meters would likely not fit the application. There are other options in the industry and while these are the leaders in technology, other velocity detectors will be considered. Even using the backbone of a COTS unit, it will require significant R&D effort in order to successfully fulfill this application.
Work produced in Phase II may become classified. Note: The prospective contractor(s) must be U.S. Owned and Operated with no Foreign Influence as defined by DOD 5220.22-M, National Industrial Security Program Operating Manual, unless acceptable mitigating procedures can and have been implemented and approved by the Defense Counterintelligence and Security Agency (DCSA), formerly the Defense Security Service (DSS). The selected contractor must be able to acquire and maintain a secret level facility and Personnel Security Clearances, in order to perform on advanced phases of this contract as set forth by DCSA and NAVSEA in order to gain access to classified information pertaining to the national defense of the United States and its allies; this will be an inherent requirement. The selected company will be required to safeguard classified material IAW DoD 5220.22-M during the advance phases of this contract.
PHASE I: Develop a concept for a threshold velocity detector, which will be considered for feasibility of manufacturing and ease of installation into the current operation. Design approaches will be developed that will allow all requirements to be met and discussed with the Government. Technology improvements and risk reduction of the aluminum mechanical components to indirect or more corrosive inhibitive materials interfaces will be another focal area of this phase. Upon selecting an approach, a concept will be defined and developed into a buildable design. Analysis will be performed on the concept to determine the feasibility of the concept to meet requirements. Manufacturing processes required to manufacture a threshold velocity detector will be investigated and defined. A cost analysis will be performed to document the total life cycle cost of a new threshold velocity detector in comparison to the legacy design. The Phase I Option, if exercised, will include the initial design specifications and capabilities description to build a prototype solution in Phase II.
PHASE II: Manufacture several prototype detectors utilizing the design and manufacturing processed defined in Phase I. These prototypes will be tested to meet the requirements of the detector and the program safety requirements. The testing will be conducted by the contractor and the Navy. When Navy specific assets are required for testing, the Navy will provide the assets or conduct the test for the contractor. In the event of any test failures, conduct root cause investigations and implement corrective actions as needed. Upon successful validation of the prototypes, the prototypes will be delivered to the Government for the completion of program integration testing and in-water testing.
It is probable that the work under this effort will be classified under Phase II (see Description section for details).
PHASE III DUAL USE APPLICATIONS: Support the Navy in transitioning the threshold velocity detector to Navy use through system integration and qualification testing. Upon completion of a successful Phase II and program integration testing, finalize the design and manufacturing processes into final production drawings that are representative of the end item as tested. Production drawings will be provided to the Government. Document and provide to the Government assembly & disassembly procedures, inspection procedures, maintenance procedures, and repair procedures that will be used to support threshold velocity detectors for the duration of their service life. Once this new detector design is qualified and determined to have cost benefits, and/or performance improvement the new detector will be cut into production. Replacement of the current inventory of the legacy detectors will also be considered as the program is expected to remain in-service for at least 30 more years. Commercial application of this technology can be in any system where a threshold velocity is required to initiate a safety intervention or sequential operation.
