Applying Side-scan Sonar and an AI-powered Platform for Environmental Protection

Over the past few years, the University of Delaware, USA, has participated in a state programme which supports rescuing abandoned crab pots from the seabed and researches technologies to make the search process more effective. It has developed advanced sonar surveys from a boat with further map storage and processing in SPH Engineering’s ATLAS AI-powered platform. The evaluations proved to be time-effective and more accurate in comparison to the detections of human annotators.  Blue crab fishing is a popular commercial and recreational activity throughout the United States. In order to catch these crabs, people use 'crab pots'. These devices are placed... (read more)

Automatic Calibration for MBES Offsets

A New Way to Monitor Your Data
Currently, calibration of MBES for hydrographic surveys is based on the traditional ‘patch test’ method. This subjective method, although rigorous, has major drawbacks, such as being time-consuming (both data acquisition and processing) and supposing that potential angle misalignments can be considered as uncoupled. A new algorithmic solution, providing an objective and repeatable first step to the automation of the calibration process, is offered through the MSPAC solution. Hydrography is essential in many marine activities: Ensuring navigational safety for nautical charts and dredging. Acquiring accurate knowledge of environmental background for offshore installations and dredging. Modelling the seabed for marine energy prospection.... (read more)

Next Step in Your Hydrographic and Surveying Career

Certification is the next step in your hydrographic and offshore surveying career, according to experienced hydrographic surveyor Bruce Calderbank. The Canadian Hydrographer Certification Scheme (CHCS) is a global scheme just as with the Australasian Hydrographic Surveyor Certification Panel (AHSCP) scheme. The CHCS certifies both hydrographic and offshore surveyors and works in both English and French. Why the ALCS? Over 60% of Canada is made up of offshore land. This land encompasses Canada’s three territories, over 3,100 Indian Reserves, and all of Canada’s National Parks. The Association of Canada Lands Surveyors (ACLS) is responsible for all Canadian land – which includes... (read more)

Fugro Starts Vattenfall Site Investigations at UK Offshore Wind Farms

Fugro has begun a four-month marine site characterisation campaign for Swedish energy group Vattenfall at two major offshore wind development sites located over 40 km off the coast of Norfolk, UK. The resulting Geo-data from Fugro’s geotechnical investigations will feed into the ground model for the Norfolk Vanguard and Norfolk Boreas wind farms, which will have a total installed capacity of 3.6 GW, enough to power more than 3.9 million homes. Working from its dynamically positioned (DP2) geotechnical drill ship Fugro Scout, Fugro is performing surveys and sampling using its proprietary SEACALF Mk V DeepDrive cone penetration testing system at both sites, and will...

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...

This is NOAA’s Plan for Deep Ocean Mapping of US Waters

Identifying and Filling Gaps in Bathymetric Coverage Deeper Than 200m
NOAA is using a systematic approach to map all US waters in support of Seabed 2030 objectives and to contribute to the complete mapping of the world’s oceans in the next ten years. Mapping within US waters is a national goal that will only be accomplished through strong coordination and partnerships with other federal agencies, academia and the private sector. The Nippon Foundation - General Bathymetric Chart of the Oceans (GEBCO) Seabed 2030 project has revitalized international and national interest in ocean floor mapping (Smith, 2018). Across US oceans, coasts, and Great Lakes waters, the National Oceanic and Atmospheric Administration... (read more)

Were Tide Prediction Machines the First Analogue Computers?

In a research paper recently published in History of Geo- and Space Sciences, National Oceanography Centre (NOC) scientist Professor Philip Woodworth describes the history and basic principles of tidal prediction machines. Invented in around 1873, tidal prediction machines were analogue computers that provided an accurate and efficient means of predicting the ocean tide. Professor Woodworth: "Although only around 10% of the tidal prediction machines ever created were in operation at the Liverpool Tidal Institute, this paper demonstrates the central role of this institution, Arthur Doodson, and the UK more generally in this area of tidal science." Captain Scott's Discovery The present-day NOC... (read more)

Fugro's CEO: “Working for a Safer and More Sustainable World”

Interview with Mark Heine
Mark Heine is chairman of the board and CEO of Fugro, with the headquarters in the Netherlands. Fugro is the leading and largest specialised survey company in the world, serving the full lifecycle of assets, and calls itself a Geo-data specialist. For the avid mountaineer Heine, challenges are never too high to take on, not even heading up a multinational in transition, from a company largely dependent on the oil and gas industry to one that wants to co-create a sustainable and liveable world. We talked to Mark Heine about leadership style, strategies for finding new employees, and Seabed 2030. About this ambitious project, Heine says ‘Commercial companies need to work together with NGOs and academia to make this happen.’ Mark Heine is chairman of the board and CEO of Fugro, which is headquartered in the Netherlands.

Shift

We had prepared an extra thick edition of Hydro International for you, full of feature articles, columns, an interview and news from and a preview of Oceanology International 2020. However, this biannual top event for hydrography and oceanography, held at ExCeL in London, which always attracts thousands of people from all corners of the globe to visit the showcase of everything that is new or proven in our industries, has been postponed due to the coronavirus. As our aim is to serve the hydrographic community in the best way we can, we therefore changed – as much as possible –... (read more)
