Operating AUVs in Shallow Water: Considerations
Positioning: • USBL? • GPS? • Inertial? Attitude, Swell and Currents: • Heave and roll in swell and wave action • Algorithms to reduce impact of swell on data • High current reduces operational window Portability and Robustness: • Launch and Recovery in shallow water • Smaller vehicles affected more by wave action • Reliability of data collection KM’s AUVs can operate in 5-10 m of water, but careful planning is required

AUVs and Risk Management: Will I Get It Back?
Risk Factors: • Mission profile • Hazards • Reliability • Human error • Risk Mitigation and Mission Management • What happens if something goes wrong?
Fully Autonomous: No interaction from operator • Pre-defined mission plan • No position updates • No supervision of payload sensors
Semi-Autonomous: Occasional Updates • Predefined mission plan • Occasional position updates using HiPAP or UTP • Occasional communication with vehicle for status • No supervision of payload data
Supervised: Most common commercial mode • Predefined mission plan can be amended during
survey • Regular position updates • Real-time data for QC sent to operator • Can change payload sensor settings on the fly • Vehicle sends status, pipeline track points etc.
