Service companies operating with ROV’s in lakes or rivers works often in turbid, muddy or polluted waters which makes the use of traditional video cameras impossible and requires acoustic based cameras.
In order to inspect and intervene on immerged structures, the French company Satif Ouvrage d’Art was delivered an ECA GROUP H300 MK2 ROV, equipped with the two acoustic systems, a precise positioning system linked to surface operators by a fibre-optic umbilical cable.
To address the customer's need, ECA Group offered relevant solutions with sophisticated equipment mounted on its Remotely Operated Vehicle H300 range :
- Horizontally - to scan the sea bottom
- Or vertically - to scan a vertical surface
A high resolution imaging sonar
Both sonars are mounted on individual skids that are assembled beneath the ROV, either individually or together, one above the other.
Satif Ouvrage d’Art expressed its satisfaction towards the performances of the delivered system as well as the support provided by ECA GROUP's team.
