MTTC / Navy Fleet Maintenance Projects-

Current Status (01/01/02)

Variable Speed Drive: MTTC has received all necessary Navy documentation and contract discussions are ongoing with NSWC/CD/Philadelphia. Funding will be provided as soon aas a contract is finalized.

Magnetic Couplings: MTTC has received all necessary Navy documentation and contract discussions are ongoing with NSWC/CD/Philadelphia. Funding will be provided as soon aas a contract is finalized.

Scullery Dishwashers: MTTC has received all necessary Navy documentation and contract discussions are ongoing with NSWC/CD/Philadelphia. Funding will be provided as soon as a contract is finalized. MTTC sponsored a trip to Philadelphia in November. Three former General Electric Appliance Park Engineers met with Navy engineers and discussed the current dishwasher issues and provided some initial feedback. The GE group is continuing to analyze the machines and components and feels that viable solutions are readily available.

UNREP Phone/Distance Line: Following a competitive procurement, MTTC has signed a contract with AtlantaLaser, Inc. to provide two bridge kits, each containing a laser rangefinder and radio transceivers. Kit delivery is expected in January/February 2002 with at-sea testing to follow in the San Diego OpArea.

ECOTherm High Temperature Insulation. All shipboard testing has been completed and final laboratory tests should be completed in the near future. A test report is being written and will be used by NAVSEA for a determination regarding fleet use.

Distiller Anti-Scale. The final Chemical Injection pump design has been completed and test/ship installation prototypes are being fabricated. EMI testing is scheduled for January 2002. Shock and vibration testing is scheduled for February 2002. BUMED approvals for ship testing has been provided. Shipboard installation will commence in April 2002 on USS CARL VINSON (CVN-70).

Boat Davit Improvements. New brake lining materials have been identified and parts lists are being updated to include them for shipboard use. New brake adjustment procedures have been develped and applicable technical manuals are being revised to incorporate these procedures. The Navy drawings are being revised to include the use of corrosion resistant materials in various troublesome davit locations. The effort has been expanded to include analysis of problems arising in the new COTS davits which are being installed on the DDG-51 class ships. The fleet should start seeing significant improvements in this machinery in the very near future.

Vertical Package Conveyors. Prototype safety light curtains have been developed and are now installed on several aircraft carriers for evaluation. NSWC/Philadelphia has ordered the PLCs (programmaable logic computers) and other hardware for prototype development and testing. PLC programming and wiring diagrams are being developed.

Composite Connectors. Keyway fit problems have been solved by the manufacturer and replacement wiring harnesses have been received by the Inservice Engineering Agent (ISEA) at NSWC/Port Hueneme/Louisville. On-mount testing will commence when a test system can be dedicated.


CIWS Acutator Cam Pin. General Dynamics Armament Division has been awarded a contract to redesign the cam pin and associated parts and to produce several sets for system testing. This effort should be completed by the end of FY-02.


Speedwrap Insulation. USS THEODORE ROOSEVELT (CVN-71) has received the test sections and has installed them onboard for evaluation. The evaluation period will run throughout the current deployment to the Persian Gulf.


Laser Induced Surface Improvement (LISI) of LCAC Lift Fan Blades. LISI coated test samples were recently successfully tested in the wind tunnel at the University of Cincinnati. The Navy has provided ST2 with LCAC fan paddles that will be coated at the University of Tennessee, Knoxville. Coated paddles will be delivered to the Navy in January, 2002 for installation in February 2002. The test LCAC is scheduled to deploy in March 2002, during which operational testing will be conducted and evaluated.


Electrospark Deposition (ESD) In-situ repair of hydraulic rams. NSWC Carderock is currently conducting Monel 400 on Monel K500 substrate testing in order to optimize system parameters. A SSN-688 class diving and control hydraulic rod has been recieved in the laboratory. This rod will be repaired in December 2001-January 2002. If successful, another test, onboard a submarine (in-situ) will be conducted.


Anti-Sweat Paint: While the MTTC/ONR laboratory testing did not substantiate the claims of the latex/ceramic paint, the Navy has decided to supplement these tests with instrumented shipboard tests to confirm the tests and claims. These real-world tests will be conducted in the near future.
