Advances in AUV Pipeline Inspection

April 28, 2014 via - Ocean News & Technology

There is a growing need for advancement in Autonomous Underwater Vehicle (AUV) technology and capabilities to perform effective deepwater pipeline inspections, allowing operators to take full advantage of the efficiencies to be gained through the use of autonomous inspection systems. Oil & Gas (O&G) companies are proactively developing new specifications for AUV pipeline inspection surveys that will necessitate AUV suppliers and survey service operators to enhance their existing capabilities. These advancements will provide superior data quality and result in improved integrity management of subsea pipeline assets while also reducing the dependency on expensive surface vessels.

Robotic submarines make waves in the oil and gas sector

April 15, 2014 via - The Engineer

AUVs are now relatively widely used by both the oceanographic research community and the defence sector, where their ability to quietly operate for long periods deep beneath the surface and to return detailed data from the seabed, makes them ideal for a range of applications. But now, dramatic mprovements in capability, coupled with our insatiable demand for energy, are driving a growing use of the technology in the offshore energy industry.

The trend was one of the key talking points at London’s recent Oceanology International conference (March 2014), where manufacturers, survey companies and energy firms all pointed to the growing use of AUVs for a range of subsea survey and inspection tasks. Indeed, Tom Hiller, a senior engineer from Teledyne Gavia — one of the leading AUV manufacturers — told The Engineer that operators are now even beginning to specify AUV solutions in contracts.

The technology certainly has some compelling advantages: AUVs are faster than the remotely operated tethered vehicles (ROVs) that are widely used in the offshore sector. And, because they’re able to operate autonomously under their own power, are less of a drain on resources: operators can put them in the water, leave them, and go off and do something else. But it’s the quality of the data they can gather that’s really driving their use. Able to fly metres above the seabed — or close to subsea installations — AUVs enable operators to rapidly deploy a range of high-frequency sonar systems and cameras to gather detailed subsea data.

What’s more, the technology also enables operators to access areas that are off-limits to other equipment, an attractive capability for an industry that’s moving into ever-more remote environments.

Bowen AD,Nereid UI: Under Ice Light Tethered ROV, Oceanology 2014, Mar 11 12013

March 11, 2014 via - Oceanology 2014

The Woods Hole Oceanographic Institution has been awarded funds by the National Science Foundation to develop a tethered robotic underwater vehicle for under-ice exploration by 2014. By employing a novel light-weight tether for data-only communications, the vehicle will provide the U.S. Polar Research Community with a capability to tele-operate, under direct real-time human supervision, a remotely-controlled inspection and survey vehicle under fixed ice at ranges up to 20 km distant from a support ship or other deployment site. Physical tethering of an underwater robot is required to provide low-latency, high bandwidth control and real-time data return. The vehicle will enable exploration and detailed exploration in under-ice environments through the use of high-definition video coupled to a suite of chemical and biological sensors. Long-range light-fiber tether technology provides the high bandwidth link necessary for real-time control under the direction of the science party which AUVs cannot meet.
