Barrett explained that the Petrel ROV serves primarily as a camera and survey sensor platform that must maintain a no- touch policy out of respect for the hal- lowed wreck sites it typically explores. “The vehicle system must provide a stable platform with excellent station keeping capabilities for close proximity video work, have a powerful propulsion system to combat currents impacting both the ROV and the entire 6,000 meter umbilical length, provide the operators with outstanding situational awareness

Synchronized pilot and co-pilot chairs allowed vehicle control and navigation to be switched between pilots, complete with touchscreen displays to support si- multaneous operation of lights, cameras, positioning and hydraulics. The system even included an automated ascent and descent for the umbilical winch that en- abled pilots to automatically synchro- nize ROV depths.

“Greensea’s OPENSEA control sys- tem is crucial to our success for extreme deep diving operations. Never before have I experienced an ROV control en- vironment as uni? ed, con? gurable or in- tegrated as this one,” Kraft said.
