Focus-2 ROTV for Fugro
Fugro Survey Limited will be operating two brand-new, purpose-built Focus-2 ROTV systems for the 2006 acoustic-pipeline inspection season. This new generation of ROTV will be equipped and operated by Fugro to offer the highest definition and most efficient acoustic pipeline inspection service in the North Sea. In addition to providing increased stability (decimetre accuracy in height above seabed, plus superior roll/pitch/yaw control), these latest generation ROTVs use state-of-the-art fibre-optic telemetry for vehicle and sensor communication, resulting in improved data quality and therefore a more precise image of the pipeline. The systems’ increased capacity allows the Focus-2 to carry a broad range of sensor packages of underwater equipment including digital side-scan sonar, multi-beam bathymetry, mechanical forward-looking sonar, mechanical scanning profiling sonar, sub-bottom profiler, fibre-optic gyro and compass. The Focus-2s will be fitted with Edgetech 4200-FS side-scan sonar systems operating at 300 and 600kHz to provide highly resolute data with much improved signal-to-noise ratios. Fully redundant hardware will maximise up time. Typical production rates will be between 140 and 180-line km per day for infield and trunk lines, respectively.
