| Comments: | Seismic software was taking GGA stamp number as time. Shot was dropped circa record 905, and a missed shot resulted in an increase of pressure to 150 bar. Time stamps went back to UTC time withhout interference, somewhere around the time the shot was dropped. Firing system resolved itself without interference. QinSY also had a PPS symchoroinisation error at the same time, which may have resulted in a lost or poor trigger signal. QinSY reported a "no time tags received" from the POSMV at 0225:15. The initial error of reading fix number as time was noticed at 0227. This error was intermittent throughout the line. |
