Phoenix International Holdings, Inc., (Phoenix) announced the successful search and recovery of components of a Coast Guard MH-65 helicopter lost off the coast of Honolulu, Hawaii in a water depth of 1,571 feet.
Given the small size of the parts critical to the loss investigation team, Phoenix personnel first conducted a bathymetric survey of the crash area and then performed a high resolution side scan sonar search. Targets of interest were then explored, mapped, and video documented using the US Navy's Deep Drone Remotely Operated Vehicle (ROV), an 8,000 ft. depth capable system. Deep Drone was subsequently used to rig and recover the main rotor and gearbox of the helicopter. Numerous smaller items of interest were picked up using the ROV's manipulators and placed in a salvage basket for recovery to the surface.
The search and recovery operation was conducted under the guidance of the Navy's Office of the Supervisor of Salvage and Diving (SUPSALV). Divers from Mobile Diving and Salvage Unit One assisted in the recovery operation by wrapping a salvage net around the rotor and gearbox to prevent the loss of any small parts as the assembly was lifted though the sea-air interface. USNS Salvor (T-ARS 52) supported both phases of the successful operation.
