“…USVs can be either remotly operated via data-link, pre-programmed or autnomous. USVs can carry any number of sensors or instruments -and be used for a wide arrange of purposes (Rumson, 2021;Zhang et al, 2019). In the context of this study, USVs are imagined as a replacement for survey vessels employed in regional survey of deep-sea mineral prospecting.…”

In the spring of 2023, the subsea industry in Norway is gearing up for an opening of the Norwegian continental shelf (NCS) for deep-sea mineral exploration and extraction. Existing research indicates that the profitability of deep-sea mining with today's technology heavily depends on high ore grades. This study explores the potential for emerging techno-operational concepts for exploration to affect the profitability of Seafloor Massive Sulfides (SMS) Industry on the NCS. By way of computer simulation, the study analyzes technologies currently, or soon, poised to enter the subsea market, with regard to their advantage or disadvantage for the SMS industry on the NCS. The study indicates that there is significant advantage in developing geophysical sampling technology for assessing mineral resources and some advantage in developing unmanned surface vessels for regional surveys. It further indicates that developing fleet operated autonomous underwater vehicle concepts for high-resolution surveys is not only moot, but possibly counterproductive. The study thereby contributes techno-operational insight for a budding industry currently looking for technology to improve commercial prospects.

This paper proposes a new lightweight, low cost, and high performance detection method of pipeline defects through compact off-axis magnetization and sensing. By deploying the magnetic sensor below the edge of the tiny magnet instead of its center, high magnetic sensitivity of defect detection can be achieved while magnetic sensing saturation can be avoided. It is experimentally demonstrated that both the sensitivity and effective lift-off value of defect detections are significantly enhanced. For various defects of different sizes and shapes, the sensitivity of the proposed scheme is mostly enhanced by 2-12 times and sometimes up to 20 times, compared with passive magnetic detection; the effective lift-off values are as high as 6 mm-13 mm, which exceeds conventional magnetic detection methods and is also much larger than the thickness of the protective polyurethane layer on the probe required by a field pipeline detector. In addition, speed independence as for the detected magnetic characteristics makes the proposed probe particularly suitable for the pipeline detector whose moving speed is unstable. Finally, its capacity of detecting a real oil-stealing hole is experimentally demonstrated.

“…Одной из практически важных проблем применения АНПА является инспекция объектов подводной промышленной инфраструктуры, включая подводные трубопроводы, коммуникации, подводные добычные комплексы и др. В [1] дается обзор по проблеме инспекции подводных объектов и обосновывается необходимость разработки новых технологий на базе использования АНПА. Выполнение инспекционной миссии требует высокой точности навигации АНПА относительно инспектируемых объектов, что необходимо для детального осмотра запланированных элементов этих объектов.…”

Inspection of underwater industrial infrastructure facilities using autonomous uninhabited underwater vehicles (AUVs) requires high accuracy of AUV navigation relative to the objects being inspected. Along with traditional navigation aids based on the inertial navigation system and sonars, technologies based on video information processing are being actively developed today. Methods based on visual odometry can provide higher navigation accuracy in conditions of local maneuvering at small distances to objects. However, during long-term movements of the AUV, such methods tend to accumulate errors in the calculation of the trajectory. Therefore, this paper proposes a navigation method that can significantly improve the accuracy of AUV movement in the coordinate space of the inspected object due to the generation and use of a virtual network of coordinate reference to an underwater object.
