  2. Saab Sabertooth current functional status • Standard autonomy functions • Obstacle avoidance • WiFi, UHF, RF, Iridium, Acoustic & Optical communication – FSO by default • Passive node/landmark navigation • Station keeping – 6 DOF capability • Sensor reactive control – Sensor makes requests • Sonar homing to structure • Torque tool actuation • Tunnel navigation • Hybrid capability – Able to autonomously switch between AUV & ROV mode • End Goal is Long Term Seafloor Residence 27/7/365

  3. The desire - The challenge - the discussions - the outcome • Desire: A resident AUV / ROV system will provide unprecedented observing capabilities before, during, and after the next eruption and formation of the highly energetic eruptive (mega) plume. • Challenge:. Resident AUV operations at Axial Seamount will require periodic battery recharging and data transfer through a docking station integrated with the existing OOI Cabled Array. Power and communications to the subsea docking station can be provided from the offshore host platform, a shore cable or surface buoy. • Discussion: Saab and the University of Washington opened discussions concerning a Seafloor Resident system for use at Axial Seamount.  Saab brought the opportunity to Modus Seabed Intervention, a subsea contracting specialist who have taken delivery of a Sabertooth this year and are the first company to offer this system into the open market.  The Axial Seamount residency development is now very much considered as a collaborative effort between the parties. • Outcome: Discussions are ongoing between Modus and Saab concerning the possible supply of a pair of 3000 Meter depth rated Sabertooth systems c/w seafloor docking stations, which would be offered to the University of Washington for long term deployment on the Axial Seamount. University of Washington Wins, Saab Wins, Modus Seabed Intervention wins and we all learn.
