MTTC / Navy Fleet Maintenance Reduction Projects
Current Status As of 03/01/2003

Aircraft Carrier Elevator (ACE) Roller Guides: This new project was approved by the January 31, 2003 Navy Working Group. Efforts will immediately commence after receipt of Navy Technical direction.

Vibracon: Shock testing has been completed at Hi-Test Laboratories. After receipt of the final test report, the Navy will determine the applicability of these devices for shipboard use.

DDG Valve Actuators: USS ARLEIGH BURKE (DDG-51) is the designated test ship. Three actuator models were installed in November-December 2002: Auma, Limitorque and Rotorque. Additionally, Bath Iron Works is installing actuators on two DDGs: Tri-Tec on USS HIGGINS (DDG-76) and Nutorque on USS GONZALEZ (DDG-66). At sea testing has commenced on these installations.

Variable Speed Drive: MTTC has awarded a contract to NAVSSES Philadelphia to develop and produce a VSD in the 18-22 HP/ft(3) power density range that meets military requirements. This effort is expected to take ten months.

Magnetic Couplings: Six couplings have been procured. Two have been installed on elevator hydraulic pumps on USS NIMITZ (CVN-68).Shortly, another coupling will be used on the Air Conditioning Chill Water Pump on a west coast CVN and three more applications on an east coast CVN.

Scullery Dishwashers: MTTC, using experienced commercial appliance engineering expertise, has visited a number of ships to observe the dishwasher in its operational environment and has developed a list of probable fixes for the problems noted. Currently, MTTC is modifying a used dishwasher to evaluate the proposed fixes and make recommendations for a MACHALT kit.

UNREP Phone/Distance Line: The results of Phase II at-sea testing was reported by MTTC in October 2002. NAVSEA is currently moving forward with plans to permit the use of hand-held lasers on maneuvering ships and to develop a robust semi-permanent system for use on MSC ships and CVNs. COMNAVSURFFOR has recently gone on record as strongly supporting this effort and encouraging the expiditious completion of the remaining efforts.

Distiller Anti-Scale: The prototype unit is ready for at-sea testing. Plans to install on a west coast ship 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.

Vertical Package Conveyors: All shore-based testing has been completed at the NSWC/Philadelphia land-based test site. Prototype systems have been installed on USS CARL VINSON (CVN-70) and USS THEODORE ROOSEVELT (CVN 71). Feedback to date has been very positive.

CIWS Acutator Cam Pin: The Navy has completed testing on the cam pin and has approved it, with very minor modification, for retrofit into fleet systems. Fixtures and instructions are being developed by General Dynamics, Burlington VT and will be issues to Navy Intermediate Level Activities (IMAs) this year. The upgrade will be installed when an ammunition handling system is brought in for maintenance at the IMAs.

Speedwrap Insulation: The 12-month inspection onboard the USS THEODORE ROOSEVELT (CVN 71) was conducted on 25 November 2002. As in the May 2002 inspection, results were positive. The pads were holding up very well and the temperature reductions in spaces such as the laundry, dry cleaning space and CPO Berthing were confirmed. As soon as the results are formally reported, NAVSEA will make a utilization determination.

Electrospark Deposition (ESD): NAVSEA comments have been received on the draft instruction. The instruction is being revised. Another qualification plate will then be produced. After the procedure has been proofed, NSWC/Carderock will proceed with repairing the control rod in their lab.

Firezone Joiner Doors: NSWC/Philadelphia has completed a preliminary acceptability criteria and goals document for the doors and components. MTTC and NSWC issued Sources Sought Notices in Commerce Business Daily on February 10, 2003. These notices requested that industry provide availaability information on their products that may meet these criteria. Upon receipt of this information, MTTC and Navy will develop a list of conforming, or nearly-conforming items for analysis and potential testing.

Hatch Gas Springs: The design for the 30 x 60-inch raised watertight hatch has been completed. A contract has been awarded by NSWC/Philadelphia for delivery of appropriate springs and mounting hardware. Upon receopt of these materials, NSWC will install on a test hatch for cyclic testing.

Self-Cleaning Strainer: A test strainer has been procured and shipped to Noise Unlimited Laboratories (NU Labs) in Annandale, NJ. The shock, vibration and EMI test plan is under review by NSWC Philadelphia. Testing will commence in the next few months.
