MTTC / Navy Fleet Maintenance Reduction Projects-

Current Status (05/01/02)

Vibracon: A contract has been awarded to NSWC/Philadelphia and the project will start in May 2002.

DDG Valve Actuators: A contract has been awarded to NSWC/Philadelphia and the project started in late April 2002.

Variable Speed Drive: MTTC has received all necessary Navy documentation. NSWC/Philadelphia has requested that contract discussions be delayed for a short period.

Magnetic Couplings: A contract and funding has been provided to NSWC/CD/Philadelphia. Procurement of the appropriate couplings will commence immediately. Test ships are being identified.

Scullery Dishwashers: MTTC has awarded a contract for Dishwasher I to NSWC/Philadelphia. MTTC has also provided the assistance of three former appliance engineers to assist in problem and solution definition. One of these engineers recently accompanied Navy (NSWC/Philadelphia) technical officials on a trip to San Diego where they observed the dishwashers on five ships. This trip was significant in that it highlighted all of the dishwasher design and maintenance problems, not just a select few. Engineering efforts are continuing.

UNREP Phone/Distance Line: MTTC took the Laser Rangefinder shipset to San Diego for at-sea testing during the week of 22-26 April 2002. USNS TIPPECANOE (T-AO-199) was the test ship. Seven different ships from 5 different ship classes (FFG, DD, DDG, CG and LHD) were serviced by UNREP. The rangefinder was tested in a number of locations and orientations. A quicklook report was immediately issued. A final test report is being written and will be issued in May-June 2002.

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 early 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).

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 (programmable 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) was the test ship during her recent deployment to the Persian Gulf. Now that the ship has returned to the U.S., BBNT will be sending representatives onboard to evaluate the installation.


Laser Induced Surface Improvement (LISI) of LCAC Lift Fan Blades. During processing of the LCAC fan blades, several technical issues arose. ST2 and the University of Tennessee believe that they have solved them by modifying the process. A contract extension has been granted in order to accomodate these changes.


Electrospark Deposition (ESD) In-situ repair of hydraulic rams. The draft process instruction for repair of SSN 688 class steering and diving control rods has been completed and NSWC/Carderock review is underway. A test plate is being prepared for qualifying the ESD procedure for the repair of the control rod.


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.
