Lynx Motor Shock Tests. This project has been
cancelled at the request of the vendor. Due to heavy workload for commercial customers,
NASA and the Department of Energy, a shock hardened motor could not be prepared in the
near future. The current commercial motor has been tested to NASA vibration specifications
and has passed, but there was some questions regarding the ability of the commercial
bearings and encoder to withstand the impact of a 400 pound hammer dropped from a height
of five feet. Rather than risk the motor's reputation, the company has elected to conduct
shock testing when it becomes necessary to construct a device that would require these
Heat Exchanger Descaler. All portions of this project are now complete. The
in-situ method has been validated for safety and has been used onboard ship. SIMAs on both
coasts have been, or are being trained in the procedure. It has been formally approved for
shipboard use by trained shore-based personnel.
Bilge Paint Qualification. USS DETROIT has been prepared and painted with Alocit
and EuroNavy paints in the main machinery space and a shaft alley. CES, Inc, SURFLANT and
NAVSEA will observe the condition of the spaces over an extended period of time. This
project is complete from the MTTC perspective.
Topside Connector Corrosion Protection. Rayvolve is currently undergoing
strenuous laboratory testing. NAVSEA has waived two tests that were considered to be
unreasonable. Testing to date has been very successful and based on these results, NAVSEA
has directed that massive shipboard testing program be conducted. The current plans are to
install over 4,000 Rayvolve covers on 19 or more ships.
K-Flex ECO Insulation. At-sea testing on USS RUSHMORE is complete. Samples of
the insulation that were subjected to temperatures in the 230-250 deg F. range exhibited
some hardening. At the request of NAVSEA, MTTC modified the contract to include laboratory
thermal conductivity testing of the sections. The preliminary test reports indicate that
there is no measurable increase in thermal conductivity. However, it has also been found
that the hardening is progressive in the I.D. in the very hot pipe applications. The O.D.
was still flexible. These tests are now complete. NAVSEA will make a judgement on fleet
suitability after reviewing the test reports. The MTTC portion of this contract is
Remote Valve Actuators. In January 2000, a "slimline" Tri-Tec actuator
was installed on USS G WASHINGTON. Underway testing was conducted during pre-deployment
workups. This actuator was removed from WASHINGTON in July. It had exhibited a tendency to
over-torque and overheat plus other problems. These conditions resulted in significant
downtime and maintenance actions. The Tri-Tec was replaced with a current actuator for its
upcoming deployment. At the request of NAVSEA, the Rosenblatt (AMSEC) contract was
modified to add a slimline Limitorque model. MTTC will procure an MX-5 model and
Limitorque will lend the Navy an MX-10 model for testing. These devices are expected to be
delivered in late August. A test ship has not formally been identified. It is understood
that AIRLANT will also be testing a Target Rock actuator on USS TRUMAN.
ECOTherm High Temperature Insulation. Test sections were installed on USS BOXER
in April 2000. Ease and cleanliness of installation was immediately noted. The sections
were not sheathed in order to observe the effects of normal shipboard operations on the
fibrous material. A mid-test inspection will be conducted in September 2000 and the final
inspection/replacement will occur after BOXER returns from deployment in 2001. The
installation will be observed during an extended at-sea period. The original project was
approved incrementally at $80K for FY 00 and $55K in FY 01. The FY 00 contract was signed
for $75K. However, it appears that the CaSi re-installation will increase to $60K. The
total is still within the approved limits.
Distiller Anti-Scale. NAVSSES has proposed a 2-year project which would require
funding that extends into FY 02. MTTC will award a contract when FY 00 funding becomes
available. SSES and NAVSEA have provided all required documentation.
Anti-Sweat Paint. There was a delay in developing a Statement of Work as a
result of personnel changes at GeoCenters. In late May, MTTC received a proposal which
appeared to conform to NAVSEA direction. Because the project will take approximately 6
months, MTTC will award a contract when FY 00 funding becomes available.
Stratica Flooring. MTTC issued a contract to CES, Inc. on May 30, 2000. The
project is expected to complete by 30 September 2000.
