MTTC / Navy Fleet Maintenance Reduction Projects
Current Status As of 04/01/2003
Carrier Elevator (ACE) Roller Guides: MTTC now has Technical
Direction from the Navy and has commenced its technical search. Penn State
University has been invited to participate. Several potential concepts have
already been identified and are being explored further with the vendors.
Shock Testing has been completed at Hi-Test Laboratories. The Navy has
determined that, initially, the shock will be approved for small applications
such as motors and pumps. To that end, a shock extension letter is being
drafted and will be promulgated in the near future. Additional uses will be
evaluated as they arise.
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.
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
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
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.
Phone/Distance Line: A change to NWP-4 that
would permit the use of laser rangefinders during most UNREPs has been drafted
and is in review. NAVSEA has purchased an updated laser/billboard station that
will be validated at sea when test ships become available.
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.
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.
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.
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.
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.
Joiner Doors: There were an insufficient number of commercial
responses to the NSWC/Philadelphia Sources Sought Announcement, issued
February, 2003. As a result, special electronic inquiries were sent to marine
door manufacturers in Europe. To date, only a few have responded. MTTC and the
Navy are currently discussing future initiatives.
Springs: Gas cylinders have been received by the manufacturer.
Few installation problems have been noted with raised hatches. Because of the
weight and design of the low profile (flush deck) hatch, NSWC/Philadelphia and
the manufacturer are having to modify the gas cylinders and hinge arms to
acount for the period of time when the hatch is opened greater than 90 degrees.
Work is progressing.
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.
