<p class="MsoNormal">Minutes for the ES Division Coordination Meeting
held on
Tuesday, January 25, 2011, at 10:30 am, in the LL CB conference room.
Attending were Lew Serna, Guy Stanzione, Ramon Gutierrez, Chuck
Thompson, Jon
Thunborg, Bob Broilo, Brent Avery and Charley Chavez. <br>
<br>
BUDGET —FY 2011 M&S budget is $17K less than FY2010. Travel is also
cut by
$7K.<span style=""> </span><span style=""> </span>Budget reports are
issued.<span style=""> </span><span style=""> </span>Remember
to charge to the correct VLA (533XXX.XXX) or VLBA (633XXX.XXX) account
when writing
your PO’s. <span style=""> </span>Antenna Mechanics should use VLBA
administrative account 633100.4626 for tools to stock the SC
maintenance
container (Bin), not to exceed $7K.</p>
<p class="MsoNormal">VLBA –MK Elevation bearing grease samples for the
“EL
synchro side” bearing still show metal particles. Fewer metal flakes
showing in
the monthly samples reported thus far probably due to flushing out of
the
bearing with grease. FD Elevation bearing Encoder side was showing
metal
particles as well. <br>
<br>
The VLBA C-Band project is funded. Antenna Mechanic and Mechanical
engineering
effort is expected to install the new feeds. The prototype will be
installed in
PT by June of 2011. Other installations will occur between June 2011
and June
2012. </p>
<p class="MsoNormal">Tentative FY 2011 TT Visits are to NL
(4/12/2011-4/18/2011),
OV with C-band horn (6/6/2011-6/12/2011, SC with C-Band upgrade
(10/17/2011-10/31/2011)
and PT(schedule on double maintenance days). <span style=""> </span>Tentative
FY 2012 trips are KP, MK & LA. </p>
<p class="MsoNormal"><br>
Foundation repairs were conducted last summer. The Rail joints were
found to be
cracking. Bob replaced most of the joints at NL and replaced bad ones
at HN. An
engineering effort to improve the rail joints is underway and will be
tried at
PT. <br>
<br>
KP will require one each wheel assembly to be replaced. A short shaft
should be
used on the spare wheel since it will fit assemblies at all sites. <span
style=""> </span>The spare will be complete as soon as the hub
is in place.<br style="">

<p class="MsoNormal">Repair of the St. Croix Subreflector is in
progress. <br>
<br>
MK dish panels that were damaged will need to be repaired for spares. <span
style=""> </span>Brent will try and locate 1/16” aluminum
sheeting on surplus for material to repair panels.<br>
<br>
SC TT Bin will need an inspection and certification before it can be
shipped to
SC. <span style=""> </span>Brent will contact Malloy to set up
a date for inspection.<br>
<br>
AZ BEARINGS – An order for 6 new bearings has been placed with delivery
expected early in 2011. An inspection trip is scheduled for Matt in
January. The
new bearings should be shipped by the end of next week.<span style="">
</span>We have one spare bearing on hand usable as
the emergency spare. Older grease samples show that antennas 25, 10 and
20, are
candidates for scheduled bearing changes. Antenna 25 is scheduled to
get a new AZ
bearing on 8/25/2011. An estimated three weeks in the AAB are required
before a
bearing change can occur. Parts from the bearings removed from antennas
are
needed for measuring and fitting of new parts and should be stored
until they
are scheduled to be shipped for repair. Fourteen bearings have been
replaced to
date. It is desirable to send bearings for refurbishment after about 3
bearings
are available to send. <br>
<br>
PROJECTS: <br>
CONTROL BUILDING STAIRWAYS—The CB balcony stairways will be replaced
with an
improved design conforming to ADA. A new concrete landing will have to
be
poured at the base of the eastern stairway and the steps replaced. The
“western” stairway repairs are complete. The eastern stairway is
barricaded to
prevent its use. Work on the eastern stairway will begin soon. <span
style=""> </span>It may cost approximately $5K to complete. <br>
<br>
ST Croix PAINT—a crew was sent to St. Croix in April 2010 to continue
brush
painting the areas where bleed through is evident. All new paint is
holding up
well. A follow up painting program at SC would cost around $17K per
visit. The
site techs are doing some painting spot repairs until enough yearly
funds are
made available for regular follow up painting trip. Some touch up and
corrosion
repairs will be done during the SC TT trip this year if possible.<span
style=""> </span>Need to have more paint delivered to prepare
for this.<br>
<br>
VLA ANTENNA FOUNDATION MOVEMENT— Problems with north arm antenna
foundation
movement needs to be investigated. It appears that the two rearward
station
pillars have been slowly separating over the years at CN5, CN6, CN7 and
BN5
with BN5 being the worst. They have separated far enough in about 33
years that
1 bolt (one on a reward pad) can no longer be used to secure the
antenna pad to
the foundation pillar. Modification of the CN5, CN6, and CN7and BN5
plates are
complete and the plates are reinstalled. This will solve the immediate
problem
of setting down antennas on these foundations. <br>
<br>
If the pillars are moving apart it is felt that there may be no
practical way
of preventing the movement. It is believed that if this is the case it
would be
more desirable/practical to build an additional foundation next to the
bad
ones. Another option is that if the pillar movement is very slow it may
be adequate
to modify/redesign the mounting plates in order to make up and correct
for the
movement. In any case it would be desirable to get inspection of the
foundations and a recommendation for action. A cost estimate for an
inspection
has been requested to an outside firm. <br>
<br>
Markers have been set for taking measurements to try and see which
pillars are
actually moving and at what rate. No change has been observed between
loaded
and unloaded measurements thus far. Recent Measurements taken continue
to show
no movement. <span style=""> </span>No measurements done in the
last couple of months.<br>
<br>
GENERATOR REPAIRS— Minor leaks were noticed at the engine rear seals
and it is
desirable to install a better fuel filtering system. This work would
cost
around $12K and has been put on the funding wish list. <br>
<br>
HOT WATER LOOP. A project is submitted to install a hot water loop
using
Correlator waste heat: The difference between the summer load and
winter load
is mostly due to heating (at least 300kW). However, even during the
coldest
mornings the cooling tower is ventilating correlator waste heat into
the
atmosphere. We already use some of the heat in the Control Building,
but by
extending the hot water loop to other buildings, we may be able to
reduce our
power demand. The WIDAR correlator will have an even higher heat output
to work
with. <br>
<br>
This project mainly consists of burying a hot water loop and using heat
exchangers similar to what many complexes of buildings use. Payback on
this
project could be as quick as 1 year. Bob Broilo will investigate and
provide
further information. This project has the potential to save $250K/year
on our
power bill. <br>
<br>
Fuel System—Diesel Tank / The diesel tank containment is upgraded to
meet state
regulations. <span style=""> </span>Outstanding items: finish
O&M plan, set up annual certified pressure tests, paint fuel lines
and
receive regulatory required training for owners/operators. </p>
<p class="MsoNormal">Modifications and upgrades to the fuel dispensing
system are
recommended.<span style=""> </span>Monitoring and removal of
dispensing pumps requiring Breakaway valves and solenoids installed by
certified installers is necessary.<br style="">
<!--[if !supportLineBreakNewLine]--><br style="">
<!--[endif]--></p>
<p class="MsoNormal">Fire Alarm upgrade- The site fire alarm is in need
for
upgrade.<span style=""> </span>It is desirable to replace the
Simplex system with a system that includes audible alarms at all
buildings and area
alarm reporting to operations.<span style=""> </span>Upgrade
would cost around $30K.</p>
<p class="MsoNormal">VLA FRM’s- After removal and inspection of the
troublesome FRM
on antenna 24 it was determined that the FRMs are in good shape.<span
style=""> </span>So far it does not seem necessary to remove
the FRMs from the antennas to perform overhaul maintenance on them.<span
style=""> </span>It may be desirable to remove and inspect a
second troublesome FRM and do another inspection; perhaps Antenna 28 to
make
sure it is not required.<span style=""> </span>Two new steel
gears to replace aluminum gears that wear are going to be stocked in
the warehouse.<br>
<br>
EVLA; <br>
Civil—SEC has installed a new 3MW utility Transformer (on 10/22/10)
since the VLA
site Utility Transformer and Generator Transformers will be marginal
once the
EVLA full load is on line. The re-closure remains to be installed at a
later
date as scheduled by SEC. Bob has ordered and received a 3MW
transformer to
replace the 2MW Generator transformer which was damaged and needs
repairs done.
<span style=""> </span>This generator is tentatively scheduled
to be installed later this year<br>
<br>
Weather station tower- ES Division has funds to install the weather
station
tower along with fiber and power. The site is selected and the tower
Installation
to occur by March- April of 2011.<span style=""> </span>Instrumentation
will be installed by the Electronics Division with ES help.<br>
<br>
EVLA Antennas— Dry air system needs to be installed. Most dry air parts
are ordered
and production design is in progress. <span style=""></span>In
late April, another 4th compressor retrofit (1 week) is scheduled
involving
moving an antenna to MP, Electrical and cryo efforts.<br>
<br>
SAFETY REPORT: </p>
<p class="MsoNormal">Reminder to all personnel to fill out accident
report sheets
as soon as possible after an accident.<span style="">
</span>Copies should be sent to all parties noted on the forms within
24 hours
