The Application of Integrity Monitoring to Offshore Seismic Survey Operations

G. Jeffrey Geier, David Musser and Neil Ackroyd

Abstract:	The paper will first review the use of Tailbuoy Systems for offshore operations, and briefly discuss the application of GPS to Tailbuoy tracking. This discussion will motivate the need for integrity monitoring. The solution method developed for Tailbuoy tracking, involving the direct computation of each buoy’s separation vector, will be described: the computation of both apriori and aposteriorf (i.e., overdetermined) statistics associated with the Tailbuoy solution will also be described. The use of these quality control measures for real time fault detection and isolation, in addition to their use as accuracy measures, will be discussed. Finally, experiences with the system during the at-sea test and operational periods will be reviewed.
