CAT 2.11 - Recovering Mary Ann
Search for Amelia Log
Recovering an AUV after a mission can actually be riskier than launching one, but the operation itself is relatively simple. When the AUV team receives confirmation that the vehicle has reached the surface, the ship pulls up alongside the AUV, where a command is sent to release a float from the AUV’s nose. This float drifts away from the vehicle extending a recovery line from the float back to the vehicle. An air-powered cannon is then used to fire a grappling hook across the recovery line and the deck team uses those lines to attach the vehicle to the LARS. The LARS winches the AUV out of the water and into the LARS docking head. The LARS A-frame lowers the AUV back into its cradle on the back deck, where it’s locked down and washed with fresh water. It’s then rolled onto the removable rails back into it’s van, where the team will download the new data, change the batteries, and get it ready for the next mission.
