Unmanned Technology Narrows Data Gap of the World’s Most Sediment-laden River

With a total length of 5,464km, the Yellow River is the second-longest river in China. Its middle section runs through the Loess Plateau, where it picks up sand and dust, making it the most sediment-laden river in the world. Yellow River runs through nine Chinese cities and affects the daily lives of tens of thousands of people who live alongside the river. To better protect the ecology of the watershed, monitoring changes in the underwater terrain and studying the pattern of river evolution can provide important data to support river management and flood control. However, technical limitations and harsh environmental... (read more)

New Subsea Survey Collaboration Completes First Joint Project

An up-and-coming name in the subsea sector has successfully collaborated with a leading provider of data collection to complete their first joint project in the south Caribbean Sea. Sulmara Subsea recently joined forces with XOCEAN to deliver a seabed survey off the coast of Aruba on behalf of SeaDrill using an XO-450 Unmanned Surface Vessel (USV). Operating 15km off Barcadera Port on the Western side of Aruba, the USV completed the 26km2 seafloor survey in 70m of water using high resolution multibeam. The objectives were to identify any seafloor features and classify the seabed to allow moorings to be safely... (read more)

New Robotic Survey Techniques to Monitor Changes in the Port

Hayle Harbour Authority has partnered with Unmanned Survey Solutions (USS) to help with the development of robotic vessels in performing hydrographic surveys in Hayle Harbour, Cornwall, England.  The aim is to monitor the effects of dredging, sluicing and periodic natural changes to the depths of the harbour in fulfilment of its conservancy requirements, and ensure safe operation to harbour users. Unmanned Survey Solutions (USS) are based on North Quay, Hayle. They design, build and operate Unmanned Surface Vessels (USVs) or ‘robotic boats’ and are often out testing new systems in local waters with permission from the Harbour Authority. During these...

Using the Apache Unmanned Survey Vessel

Techniques in Bathymetric Survey
This paper explores the various features of the Apache USV series for efficient seafloor-level mapping. The CHCNAV hydrographic survey software is used for data recording and analysis. It provides results in the form of 3D models of the ground, contours and depth. (This story is brought to you by CHCNAV) Bathymetry is the study and mapping of the seabed or lake bed. It consists of obtaining measurements of the depth of the ocean or lakes and is equivalent to the mapping of the Earth’s topography. In general, only limited information is known about the seabed and lake beds. Existing maps... (read more)

AutoNaut USV Maps North Sea Soundscape during Lockdown

AutoNaut has played a vital role in enabling the Flanders Marine Institute (VLIZ) to seize upon the quiet of lockdown to map the underwater soundscape of the Belgian section of the North Sea. Using its near silent AutoNaut USV research vessel Adhemar, VLIZ has been able to record current noise levels, which it will compare with the marine soundscape once normal sea traffic and marine activities recommence. This will help to determine the impact of man-made noise on natural sea life and the marine environment, building a picture of the marine soundscape in conditions that may never again be possible. Following... (read more)

First Fully-autonomous Shallow Water Survey

Geodata specialist Fugro has completed the Middle East’s first fully autonomous geophysical shallow-water route survey. Controlled from their remote operations centre in Abu Dhabi, an unmanned surface vessel (USV) captured a full range of geophysical data across a survey area of some 40km out from the coast of Abu Dhabi to support a client’s critical project, entirely remotely. The results of the fully autonomous geophysical shallow-water route survey comprised conductivity, temperature, depth and salinity (CTDS) profiles, bathymetry data, seabed imaging, sub-bottom profiles, and ferrous object detection such as pipes, etc. The efficiency gains and material reductions from using Fugro’s remote...

Using Unmanned Surface Vehicles for Bathymetric Dam Imaging

A North American Case Study with Wide-ranging Applications
Inspection of dams is a high-risk task for divers because of strong currents and eddies. The use of emerging technologies such as unmanned surface vehicles equipped with echosounders and sonars can lower those risks. Such systems can perform subsurface dam inspections quickly and effectively without putting humans at risk, as this US case study shows. Overused roads, outdated railway systems, brittle power grids, crumbling bridges and suchlike all take a toll on the economy and, tragically, sometimes even lead to loss of life. Failing infrastructure is an issue for most countries, and likely more so in developed nations that still... (read more)

Fugro Starts NOAA Project to Update Florida’s Nautical Charts

Fugro has begun work on its first task order under a recently awarded multi-year hydrographic services contract with the US National Oceanic and Atmospheric Administration (NOAA). Located off the north-west coast of Florida, the project involves the acquisition of high-resolution bathymetry data over four sites totalling approximately 1,475 km2. Deliverables will be issued to NOAA by December and they will use this information to update charted depths and features in the region, many of which predate the 1950s. To streamline the data collection, Fugro will deploy its new FAS-900 unmanned surface vessel (USV) as a force multiplier on the project.... (read more)

Joining Forces to Create a Communication System for USVs

SEA-KIT International, a provider of hi-tech solutions for the maritime and research industries, is joining forces with Essex academics to create a secure and intelligent communication system for the control of unmanned surface vessels (USVs). Essex (UK)-based SEA-KIT has won funding as part of a Knowledge Transfer Partnership (KTP) by the UK government’s innovation agency, Innovate UK. The funding will help SEA-KIT to commercialize its USV offer by building bespoke vessels for its clients in the offshore energy sector who conduct surveys for offshore wind and oil and gas infrastructure.

Enhancing Port and Harbour Security with Unmanned Surface Vehicles

As readers of Hydro International know, the world’s ports and harbours are crucial to global trade. From Singapore to Antwerp, to Shanghai, to Rotterdam, to Los Angeles to other mega-ports and hundreds of other smaller ports, these crucial nodes are critical to world trade. A disaster like a fire, explosion, or a major oil spill could close one of these ports for an indefinite time. The secondary effects of such a catastrophe could include releasing a huge amount of pollution into rivers and oceans.
