Oceaneering Tests AUV on Pipeline Inspection Pilot for TotalEnergies
TotalEnergies and Oceaneering International, Inc. have completed a pipeline inspection industrial pilot using a Freedom™ Autonomous Underwater Vehicle (AUV).The capabilities observed during the pilot delivered on the ambition of TotalEnergies to reduce the environmental impact while assuring the integrity of sub-marine pipelines, contributing to TotalEnergies ambition to be Net Zero by 2050. The application of the technology represents a reduction in time, and emissions, of an estimated 50% compared to existing methods with equivalent quality of the inspection and opportunity to exceed data
Optimizing Cathodic Protection Survey Using Non-contact Sensors
The principle behind sacrificial anodes, which are used to safeguard underwater pipelines and structures from corrosion, is relatively straightforward. Made of alloys like aluminum, Zinc and is some cases Magnesium, the anodes are more reactive in the electrochemical process than the steel used in pipelines and other subsea structures. When connected to a structure, the anodes willingly 'sacrifice' themselves by corroding first, effectively redirecting the corrosion away from the vital structures.The methodology, known as Cathodic Protection (CP), is used on all underwater structures that
DeepOcean Gets Pipelines Inspection Job in North Sea
Ocean services provider DeepOcean has been awarded a contract by Equinor to deliver inspection and survey work on the operator’s pipelines in the North Sea.DeepOcean’s scope of work includes pipeline inspections, seabed mapping, and ad-hoc pipeline survey and light construction work. The agreement, whose value was not disclosed, is valid for 2024.In addition to its extensive infield pipeline networks, Equinor also has operational responsibility for the world's most extensive subsea pipeline system for transportation of gas.The latest contract is an additional award under DeepOcean’
New Tech for Ultrasound Inspection Subsea
FORCE Technology introduced a new generation of its P-Scan ultrasound scanner for subsea inspections. P-Scan 5 is designed to be easier to configure for a wider range of geometries and asset integrity applications, including regular inspection of submerged pipelines, flowlines, subsea templates, manifolds and offshore wind turbine subsea structures.Whether deployed by divers or remotely operated vehicle (ROV), FORCE Technology can now deliver more complete reports on a submerged structure’s condition, based on data acquired by the latest generation phased-array scanning featured in
Oceaneering's Hybrid AUV/ROV Achieves TRL 6 For Pipeline Inspection
said that its Freedom, a hybrid AUV/ROV system, is the result of a long-term collaborative relationship between Oceaneering, TotalEnergies, and Chevron dating back to 2014, with Equinor joining the collaboration in 2019. In 2014, Oceaneering began efforts to optimize the delivery of a pipeline inspection service from an AUV. "The close association between customers TotalEnergies, Chevron, and Equinor, and Oceaneering as developer, has ensured that the specification and requirements of the improved pipeline inspection AUV have been realized within both the hardware design as well
Argeo Taps Eelume 'Snake Robot' for Autonomous Underwater Inspection
Argeo AS selected Eelume’s autonomous ‘snake robot’ to assist in its operations, the first commercial contract for this new tech which was developed with the assistance of Kongsberg Maritime, a majority shareholder in the venture.“We believe that this is just the beginning of a major shift in how the industry conducts underwater operations. There is a need in the market for this type of solution, and we anticipate a significant requirement for more robots of this type in the long term,” says Trond Crantz, CEO, Argeo. “In addition to lowering carbon footprint and
