Long Tunnel Inspection

Despite a number of corners and turns, Atlantas Marine has been able to penetrate 1500 meters into a tunnel with a diameter of only four meters using a custom-built long-umbilical remotely-operated vehicle developed by Ocean Modules.

The ROV system conists of standardised V8 ROV and surface unit components connected by a 2100 meter umbilical tether cable with a motorised tether management and cable counter system.

The entire survey was documented with the aid of two cameras, a profiler and SPOT.ON, a patented survey management software for one-touch data acquisition and automatic reporting.
