Fugro’s ROV Survey and Monitoring Help Install World’s Longest Subsea Interconnector

Fugro has completed a contract for Nexans to provide remotely operated vehicle (ROV) survey and monitoring support services to lay the North Sea Link cable through a mountain and along a lakebed in Norway. National Grid NSN Link and Statnett are building an electricity interconnector between Kvilldal in Norway and Blyth in the UK which, on completion, will be the longest subsea interconnector in the world. Fugro’s innovative survey and monitoring solutions supported the installation of two cables through the mountain between Hylsfjorden and Lake Suldalsvatnet, and along the lakebed at a depth of 210m. Real-time monitoring and near-real-time processing... (read more)

Beagle Gulf Hydrographic Survey in Full Swing

Precision Hydrographic Services (PHS) has recently been contracted by the Australian Hydrographic Office (AHO) to undertake a hydrographic survey in Beagle Gulf, located in the Northern Territory of Australia, to determine the local bathymetry for navigational purposes. The hydrographic survey is taking place between the beginning of July 2020 and the end of August 2020, with two survey vessels, the Limitless and PHS Zephyr, both displaying flags (India over Romeo – conducting survey operations) while undertaking survey. The survey will be measuring oceanographic parameters including currents, tides and wave height in the immediate area, with oceanographic measurements recorded by utilizing... (read more)

Submerged Munitions, No Hazard Left Undetected

Minimum Requirements for Munitions Detection at Sea
Munitions in the sea pose a risk to the sustainable development of the ocean economy. In particular, they remain a global challenge during the construction of wind parks, pipelines and other infrastructure. To ensure high-quality performance during the execution of the necessary maritime munitions detection and clearance operations, industry experts and scientists from Germany have defined a set of requirements. These are particularly important in the detection phase which requires the attention of hydrographical surveyors. Safe access to large areas of the seafloor is a prerequisite for offshore economic development. However, this ability has been compromised by the presence of... (read more)

Sonardyne Underwater Positioning to Support Fugro’s Offshore Wind Operations in North America

Leading geo-data specialist Fugro has chosen underwater positioning technology from Sonardyne for its upcoming offshore wind farm projects in North America. The company has ordered three Sonardyne Mini-Ranger 2 Ultra-Short BaseLine (USBL) underwater positioning systems to support shallow water site characterisation surveys, and a standard Ranger 2 for positioning geotechnical boreholes that will influence turbine foundation design and installation. In addition, Fugro has also ordered Wideband Sub-Mini 6+ (WSM 6+) and Nano transponders to fit to the underwater equipment it will be tracking with its new USBLs, including side-scan sonars and transverse gradiometer systems.  Very shallow and high-elevation tracking Mini-Ranger...

Mapping Submarine Groundwater Discharge with Thermal Infrared Imaging

Using Cutting-edge Technology and High-resolution UAS
Submarine groundwater discharge (SGD) is a significant part of the water cycle that delivers anthropogenically derived and naturally occurring nutrients to coastal waters. As part of the drive to develop methods to prevent the degradation of coastal water quality, research conducted at the University of North Carolina Wilmington attempts to address the ambiguity associated with SGD point source locations. This case study outlines how cutting-edge high-resolution unmanned aerial system (UAS) thermal infrared (TIR) imaging methods have been coupled with the newest technology for continuous and autonomous SGD monitoring. Submarine groundwater discharge – the process in which groundwater flows down-gradient through... (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)

Mariscope Unveils Rescue and Support ROV with Full Integration

Mariscope Meerestechnik has added another new model to its fleet. The Commander MK III Rescue is an ROV with features that stand out in a vehicle of this class. This ROV serves as an example of how Mariscope customizes a model and executes system integration, according to the specific needs of its clients. The first Commander MK III Rescue vehicle has been installed on board the shadow boat HODOR as the rescue unit for the SEAmagine Aurora 3 manned submarine, which this vessel carries and operates. Like the Aurora, this ROV has a working depth of 1,000 metres, thus guaranteeing support... (read more)
