Remotely deployed and operated drone-based sealed tank inspections

A remotely deployed and operated drone-based sealed tank inspector comprises a direct replacement of normal hatch cover which is a sealed hatch cover comprising electrical penetrations, a sealing cable transit, and a predetermined set of eyelets for retention of lifting slings, and is handled using small hoist and parking stand. Drone-based inspections, including ultrasonic (UT) and visual inspections, may be remotely accomplished by deploying the remotely deployed and operated drone-based sealable tank inspector and using it for inspection and testing, including visual inspection, such as those required to be performed inside a sealed, inert-environment tank.
