MTTC / Navy Fleet Maintenance Reduction Projects-

Current Status (07/01/02)

Vibracon: A contract has been awarded to NSWC/Philadelphia and shock test planning has commenced. A minimum of two pumps and a compressor will be barge-shock tested using Vibracon chocks as the leveling and hold-down devices.

DDG Valve Actuators: NSWC/Philadelphia has been awarded a contract to conduct at-sea test and evaluation. They are currently interviewing vendors and factory representatives have visited USS ARLEIGH BURKE (DDG-51) to look at the intended test application.

Variable Speed Drive: Upon award of contract to NAVSEA/Philadelphia, they will install VSDs on CVN-68 class ships for operational testing.

Magnetic Couplings: NSWC/Philadelphia has been awarded a contract to evaluate and test potential solutions to the water level indicator problems on fleet units. The ISEA has identified several alternatives and is in the process of obtaining components for testing.

Scullery Dishwashers I: MTTC continues to  provide technical assistance to NAVSEA Philadelphia by employing former General Electric Appliance engineers to analyze the current  problems and provide recommendations. A contract has been awarded to NAVSEA/Philadelphia and analysis of potential solutions has commenced.

Scullery Dishwashers II: This project was approved in January 2002. NAVSEA has provided necessary documentation. Upon award of contract to NAVSEA/Philadelphia, engineering and test efforts will commence. Fleet ships, in three homeports will be used to verify replacement parts in CY 02.

UNREP Phone/Distance Line: The at-sea testing of the hand-held laser rangefinder was conducted on USNS TIPPECANOE on April 22-25, 2002. A final report was issued by MTTC on May 22. Based on the findings and recommendations, NAVSEA has requested that MTTC extend its efforts and conduct at-sea testing of a billboard display that would be used on the replenishment ships. MTTC has agreed and preliminary planning is underway. Laser Atlanta will modify the rangefinders with an inclinometer that will permit the calculation of horizontal range, given slant range. Laser Atlanta will also loan a display to the Navy for further testing.

Distiller Anti-Scale. The Prototype unit is ready for at-sea testing.  Plans to install on a west coast CVN have been delayed because the USS CARL VINSON (CVN-70) (Smart Ship) availability work package has been overloaded.  NSWC/Philadelphia is now looking at the next available ships – USS JOHN C. STENNIS (CVN-74) or USS THEODORE ROOSEVELT in Norfolk.

Vertical Package Conveyors. NSWC/Philadelphia has made great progress in the past quarter. The PLC, Light Curtain, chain auto oiler and variable drive has been installed and programmed. Testing at the land-based test site will begin soon. Installation of the PLC has been accomplished on the USS HARRY S. TRUMAN (CVN-75) (3 conveyors) and is underway on the USS CARL VINSON (CVN-70). Design of the light curtain for combatants has begun.

Composite Connectors. The Navy has received the MTTC–provided wiring harnesses with composite connectors from LiteCom, Inc. After testing on Phalanx CIWS systems, it has been decided not to adopt the concept for fleet-wide application. While there is great potential that may later be realized, the Navy engineers were not comfortable with the lack of solid lock on the bayonet-style device. Further development is anticipated.


CIWS Acutator Cam Pin. Design and drawings are complete. Prototype scoop disc assemblies have been built and will be shipped to the Navy in the next few weeks for on-mount testing.  


Speedwrap Insulation. During the first week of May, BBNT, Inc. conducted a six-month evaluation on the USS THEODORE ROOSEVELT (CVN-71). The sailors especially appreciated the laundry application since it appeared to lower temperatures by at least five degrees F. Flex hoses were noted as an unexpected hand-and-glove application. A 12 month inspection will be conducted in the late fall.  


Laser Induced Surface Improvement (LISI) of LCAC Lift Fan Blades. The contractors, ST2 and the University of Tennessee encountered problems in adjusting the heat balance so the coating would adhere without damaging (annealing) the Aluminum 6061 alloy substrate. The contract expired without delivery of fan blades for at-sea testing. This project has been terminated, however ST2 is continuing work under other funding vehicles. A solution to the problem may still be forthcoming.  


Electrospark Deposition (ESD) In-situ repair of hydraulic rams. Prior to utilization on fleet asset diving plane rods, the ESD process must be formally approved by NAVSEA. It is considered to be a SUBSAFE item. A draft process instruction has been written and is in routing. Comments are already being received. Given the critical nature of the equipment, a quick response is anticipated.


Anti-Sweat Paint: The MTTC-sponsored testing at Naval Research Laboratory has been completed. Based on these results the Navy has decided to conduct additional testing onboard designated ships. This is ongoing and will be completed in 2002.
