![]() Errors can be systematic, positioningor acoustic related and require the application of various algorithmsand filters to resolve. The data gathered needs to be processed with specialised software,which is used to remove errors, geo-reference the measurements andto generate outputs for reporting. Currentprofilers are used to determine the ROVs position in the water columnand telemetry systems, such as ultra-short baseline (USBL), use phasedifferencing to position the ROV in relation to the ship’s GPS system.These sensory inputs combined with video cameras have provideddetailed insight into the condition and situation of the pipeline overmany years. Pipe trackers are essential tools for locating buried pipes. This is a valuabletool to help determine if the pipe is spanning the seafloor rather thansitting on it. ![]() ![]() Multi-beam sonar systems are commonly mounted on ROVs to mapthe pipe in the context of the surrounding seafloor. ROVs are maintained andoperated by a ROV crew which typically consists of five or six peopleand are equipped with a variety of sensors to accurately position andinspect the pipe. Pipeline inspection surveys have been traditionally performed byRemotely Operated Vehicles (ROVs) which are connected to themother ship by an umbilical cable.
