Subsea pipeline leak inspection by autonomous underwater vehicle
, 2021Faced with the difficulty in finding and locating leakage points of submarine pipelines timely as well as the high cost of pipeline routine inspection, a scheme using autonomous underwater vehicle (AUV) equipped with multibeam echo sounder (MBES) and ...

Applied Ocean Research, 2021
In this paper, a composite learning tracking control scheme is developed for underactuated autonomous underwater vehicles (AUVs) in the presence of unknown dynamics and time-varying disturbances. Line-of-sight (LOS) tracking control is employed to handle

IEEE Transactions on Circuits and Systems - II - Express Briefs, 2021
A line-of-sight (LOS) guidance law with an explicit model predictive control (MPC) is proposed for an underactuated autonomous underwater vehicle (AUV). The derived LOS law is based on quaternion angles thus avoids the problem of singularity inherited in

Cable Route Surveys Utilizing Autonomous Underwater Vehicles (AUVs)
Marine Technology Society Journal, 2000Detailed geophysical surveys are required in both deep and shallow water to avoid potential hazards and to provide for the installation and safety of fiber optic telecommunication cables. Unfortunately, data obtained in potential burial zones with existing technology are slow and often data accuracy may be questionable.

Energy systems for FAU AUVs [autonomous underwater vehicles]
Proceedings of the 2002 Workshop on Autonomous Underwater Vehicles, 2002., 2003The AUV research program at Florida Atlantic University (USA) has focused its design efforts on battery powered AUVs, developing both the battery packs and power distribution systems that provide a robust energy system for the AUV. This paper focuses on the development of our energy systems on their 3 AUVs (Ocean Voyager II, Ocean Explorer and Morpheus)

Hydrothermal exploration using Autonomous Underwater Vehicles (AUVs)
10th International Congress of the Brazilian Geophysical Society & EXPOGEF 2007, Rio de Janeiro, Brazil, 19-23 November 2007, 2007Thirty years after the first discovery of seafloor hydrothermal venting no more than 90% of the global mid-ocean ridge crest has been investigated for seafloor hydrothermal venting. Until recently entire ocean basins had remained unexamined. What was needed was a new, more efficient mode of exploration that could not only detect for the presence of ...

Alister – Rapid Environment Assessment AUV (Autonomous Underwater Vehicle)
2010ECA is mainly known worldwide for its successful PAP family (mine disposal systems). In the late 1970s, ECA designed the first operational AUV, named EPAULARD for IFREMER. Using its know-how gained over the years in designing and building various types of free swimming and inspection underwater vehicles, ECA decided in spring 2003 to develop the A3000,
