RV "KRONPRINS HAAKON": POWER REQUIREMENTS, FOR UPS <back to main page>
INTRODUCTION
This is an estimate of power requirement of seismic equipment in "IKT CENTRAL" (7th deck), during 2D seismic data collection, in relation to UPS dimensioning.
POWER REQUIREMENTS
| SYSTEM
| REPRESENTATIVE BRAND/MODEL
| DOC
| POWER CONSUMPTION
| HOW CERTAIN?
|
| Airgun control system
| Teledyne Real Time Systems
"HotShot"
| -
|
| (From markings above power connector]
|
| Streamer depth control ("Birds")
| ION GEO DigiBird
| -
|
- Laptop (in "IKT-central" 7th deck): 50 W
- "Birds" are powered by their own batteries
| Fair estimate
|
| Streamer
| Geometrics
GeoEel Digital Streamer
| Data sheet
|
- 0.6W/channel * 240 channels = 144 W
| Value from data sheet.
|
| Seismic recording
| Geometrics CNT-2 controller + laptop
| -
|
- CNT-2 Controller: 10 W
- Laptop: 50 W
| Fair estimate
|
| Magnetometer
| Geometrics G-882
| Link
|
- Towfish with sensor: 24-32Vdc supply, 0.5A (stable) => 15 W
- Power supply, own consumption: 5 W
| Fairly good estimate
|
| Gravity meter
| L&R sensor, ZLS electronics
| Link
|
- Laptop (in "IKT-central" 7th deck): 50 W
- Graviy meter proper (separate room 2nd deck): 400 W
| Accurate estimate
|
| TOTAL POWER CONSUMPTION (adding numbers in yellow):
| 230+50+144+10+50+15+5+50 = 554 W
