[Escoordminutes] ES Div. Coordination Meeting Minutes-May

[Lew Serna]

Minutes for the ES Division Coordination Meeting held on Tuesday, May 3, 
2011, at 10:30 am, in the LL CB conference room. Attending were Lew 
Serna, Guy Stanzione, Ramon Gutierrez, James Sullivan, Jon Thunborg, Bob 
Broilo, Brent Avery, Martin Lopez and Paul Savedra.

BUDGET ---FY 2011 M&S budget is $17K less than FY2010. Travel is also 
cut by $7K. Remember to charge to the correct VLA (533XXX.XXX) or VLBA 
(633XXX.XXX) account when writing your PO's.  Antenna Mechanics should 
use VLBA administrative account 633610.4626 for tools to stock the SC 
maintenance container (Bin), not to exceed $7K.  FD elevation bearing 
job is funded.  C Band funding is also available for the FD trip.

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 and will be replaced on 5/17/2011-5/20/2011.

The VLBA C-Band project is underway Antenna Mechanic 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.

FY 2011 TT Visits-- NL is complete, OV with C-band horn 
(6/9/2011-6/15/2011), SC with C-Band upgrade (8/2/2011-8/11/2011) and PT 
(schedule on double maintenance days).  Tentative FY 2012 trips are KP, 
MK & LA.

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 this month.

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.  The spare will be complete as soon as the hub is in place.

Repair of the St. Croix Subreflector is close to completion.

MK dish panels that were damaged will need to be repaired for spares. 
 Brent will try and locate 1/16" aluminum sheeting on surplus for 
material to repair panels.

SC TT Bin is inspected and certified for it shipment to SC.  The Bin 
should be outfitted with tools before being sent in June.


AZ BEARINGS --6 new bearings have been delivered with a total of 7 
bearings on hand. One bearing will be marked 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.   Matt 
Evatt will be trained as a bearing change supervisor.

PROJECTS:
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 stairway 
replaced. The eastern stairway is barricaded to prevent its use. Work on 
the eastern stairway has begun and should be completed in a couple of months

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.  Need to have more paint delivered 
to prepare for this.

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. 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. 
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.  No measurements taken 
in the last couple of months.

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.

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. 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.

Fuel System---Diesel Tank / The diesel tank containment is upgraded to 
meet state regulations.  Outstanding items: finish O&M plan, set up 
annual certified pressure tests, paint fuel lines and receive regulatory 
required training for owners/operators. Modifications and upgrades to 
the fuel dispensing system are recommended.  Monitoring and removal of 
dispensing pumps requiring Breakaway valves and solenoids installed by 
certified installers is necessary. Hand railing also should be installed 
(by NRAO).

Fire Alarm upgrade- The site fire alarm is in need for upgrade.  It is 
desirable to replace the Simplex system with a system that includes 
audible alarms at all buildings and area alarm reporting to operations.  
Upgrade would cost around $30K.  This project is under consideration for 
 next year's "project funding".

VLA FRM's- After removal and inspection of the troublesome FRM on 
antenna 24 it was determined that the FRMs are in good shape.  So far it 
does not seem necessary to remove the FRMs from the antennas to perform 
overhaul maintenance on them.  It may be desirable to remove and inspect 
a second troublesome FRM and do another inspection to be sure removal 
from antennas is not necessary (perhaps Antenna 28).  Thus far two new 
steel gears to replace aluminum gears that wear are going to be stocked 
in the warehouse and replaced as they fail.  This task can be performed 
while the FRM is on the antenna.

Quad Leg Rust---one of Antenna 13's upper quad legs was found to have 
rusted badly and repairs will be made.   A thorough inspection of all 
antennas for this and other structural elements will be made to 
determine future actions.

Asbestos Abatement training---relevant personnel need to attend renewal 
training.

The Tech Services 1mW Transformer and MD panel will be installed later 
this year.

EVLA;
Civil---SEC has installed a new 3MW utility Transformer (on 10/22/10). 
The re-closure (utility breaker) remains to be installed at a later date 
as scheduled by SEC. A 3MW transformer to replace the 2MW Generator 
transformer has been delivered. This transformer junction box was 
damaged and needs repair.  This transformer will be installed later this 
year

Weather station tower- This task is complete.  Instrumentation will be 
installed by the Electronics Division with ES help.

EVLA Antennas--- Dry air system needs to be installed. Three units are 
ready for installation. Most dry air parts are ordered.

 Antenna 5 has received the 4th compressor retrofit (1 week).
