UTEC adds to AUV fleetVessel & ROV News // May 2, 2014
UTEC Survey has doubled its AUV fleet to four vehicles in response to what it described as "increasing demand for AUV services."
The company now operates a fleet of four identically equipped 1,000m-rated AUVs.
The company said the fleet "offers clients enhanced subsea positioning, robust operational performance, low logistics designed for dual mode operations utilizing client’s vessels of opportunity, in other words a highly flexible system."
The AUV consist of separate modules, enabling operators to change configuration by adding or removing sensor modules, subject to the requirements of each mission.
Typical missions have included pre-route survey, structure and pipeline inspection, scour monitoring and shallow environmental investigation.
The ability to rapidly reconfigure the AUVs means for example that a mission undertaking seafloor bathymetry can be reconfigured on deck to undertake the next mission with a suite of environmental sensors for locating hydrocarbon seeps or pipeline leak detection.
The AUV's endurance with a full sensor suite is approximately six hours; its low logistics and small backdeck footprint allows for multiple AUVs being deployed at one time providing data acquisition on a 24 hour basis.
Developments and enhancements to standard off the shelf systems include: a sub-bottom profiler module; enhanced surface “DGPS” acquisition; subsea ‘acoustic’ positioning; a ‘magnetometer’ ferrous metal detection module; a seep/leak detection module and photogrammetry capability for subsea structure/pipeline inspection.
