C-ATLANTIS - WORK LIST OF THINGS THAT NEED TO BE REPAIRED
For May 20, 2015
1. DP system, Glonass DGPS is not working. There is an antenna
on the mast that has been struck by lightning, this needs to be
changed out, It is A UHF antenna according to the antenna plan
drawing. Maybe this has something to do the signal.2. Radar is not
reporting course and speed. Up-date Radars were working after the
tech changed the relay circuit feed on the 23 of April but it has
gone out again. The radars are getting course feed from the gyro
but there is no position and speed input from the GPS. Both Radars,
the Rutter radar, Aptomar, Chart plotter and SSB is not receiving
GPS input. And our SABB R4 main GPS signal quality is poor.3. In
the DP system the wind sensor # 2 is not working. The wind sensor
on the mast is working and the wind sensor monitor in the
wheelhouse is working fine, but in the DP system it is not working.
It seems that it is not getting the signal from the sensor.4. The
current meter cable broke and needs to be repaired. This happen
while servicing the davit and cable.
We need an electrician to re-splice the cable.5. Condenser fan
motor for main A/C has developed what appears to be a bad bearing.
We have isolated the fan motor and are now running on one fan at
reduced A/C capacity. We need this motor replaced and sent in to
office for rebuild. It would be a good idea at this time to replace
both motors since there has been no maintenance that we are aware
of for past three years.6. The MAIN-A/C UNIT (cools the forward
house @ galley, 01, 02 deck air-handlers) now has several problems
(see ITEM 5 above), and has started passing un-expanded refrigerant
to compressor suction-side (flooding-through).This is usually a
result of a bad TXV valve, either its bulb has lost its charge or
the valve seat has become scored and does not close 100%.
Our chiller (immediately behind compressor where the refrigerant
cools the circulated chill-water) also is routinely icing-up inside
the water passages, causing complete blockage of the chill-water
discharge line from the pump. This can be prevented by repairing or
replacing the TXV valve, and any future or further recurrence can
be prevented or greatly reduced by installing a small diameter (3/8
inch or 1/4 inch) copper tubing at the chill-water pump discharge
gauge port that runs up the exhaust stack to the chill-water
head-tank, and then adding several gallons of anti-freeze or glycol
to the water.We also need the refer-techs to take a look at all
alarm/shut-down functions for super-heat, low suction pressure,
high discharge pressure.
If possible, please send the two Romanians that were here on our
vessel (February 25-2015?) recently. They seem smart and capable
and speak English. They are about 40 years old (not the guy who
broke his leg), but we cannot remember their names. We would really
appreciate.7. Fan propeller on condenser fan motor @ compressor
unit in upper engine-room failed (cracked). This fan is on the
walk-in refer-box condenser unit in upper engine-room. Replaced
with undersized fan propeller as temporary solution. Specific
ordering info, sizing, etc., on requisition # 06052015-210853
(BOTTOM ITEM ON PAGE). We found a very good match for this exact
propeller on the McCombs website. We would be very happy to help
with any clarification, ordering help, or additional information.8.
Galley walk-in freezer evaporator is continually icing-up and no
longer transferring heat to refrigerant through evaporator fin
passages. Freezer temperature has slowly climbed so that we had to
de-ice the evaporator two times in past ten days, with it quickly
icing-up again. Need techs to examine system for proper de-icing
function.9. Starter for davit ram system motor was not working and
vendor techs came (22-4-15) and found a faulty CURRENT OVERLOAD
PROTECTOR. They jumped this power-leg so davit would work
temporarily. The techs told Thiago and Tom they would order a new
one and install it at next crew-change. We are due for our PORT
STATE INSPECTION at next crew-change (20-5-15) and will need this
part installed upon arrival in Rio10. The 400 meter boom is not
inflating all the way. In the outermost section of the boom (first
200 meter part of the boom) one section inflates and the other one
next to it is not inflating. Update: 2/5/15 deployed the boom again
and we discovered that one of the air hoses has a leak in the front
section of the boom. At end of drill we opened all dump valves to
deflate boom in the normal manner so we could begin to reel it in.
Normally a great volume of air is discharged through these valves
to deflate boom. Now very little are exits through the dump valves,
as a further indication of problem. This will need to be examined
and fixed next time in port.
