Fugro Begins Extensive Site Characterization for ScottishPower Renewables’ East Anglia Hub

Fugro has begun the geophysical survey phase of a large multidisciplinary site investigation contract worth around GBP55 million for ScottishPower Renewables’ (SPR’s) East Anglia Hub project. The phased site investigations are scheduled to finish at the end of 2021 and support the development of wind farms in the UK southern North Sea over an area of more than 800 square kilometres. The results from Fugro’s site characterization will feed into SPR’s ground models for the East Anglia Hub and support seabed mobility assessment, foundation design and cable-route engineering. Operating from dedicated geophysical survey vessels, the Fugro team began the UXO... (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)

Dutch Flood Defence, the Natural Way

When the Dutch government and research institutions wanted to monitor how waves and currents would affect the pioneering use of artificial sand banks to protect a levee in a non-tidal freshwater system, Nortek was selected to supply key measuring instruments and set up the data telemetry system. The Houtribdijk is a 25km-long levee, or dike, separating two large artificial lakes, the IJsselmeer and the Markermeer. The lakes and accompanying levees protect the Netherlands from the forces of the North Sea’s extreme weather events, and from flooding from inland freshwater river systems. After years of exposure to the elements, the Houtribdijk... (read more)

ASL Environmental Sciences Assists with Oceanographic Data Collection for Labrador Marine Research and Monitoring

In a collaborative effort with the Nunatsiavut government and Dalhousie University to measure ice, water current and other physical and biological properties of the marine environment, ASL Environmental Sciences Inc. contributed a prototype Log Ice Profiling Sonar (LogIPS). On 15 February, the sonar was deployed on a taut-line mooring in the waters off Nain, Nunatsiavut, Labrador, Canada. The mooring also contained an acoustic doppler current profiler (ADCP), as well as data loggers for chlorophyll, turbidity, temperature-salinity and dissolved oxygen. The mooring was deployed through a hole cut in the sea ice, with an open-water recovery planned for later this year. The... (read more)

How a Hydrographic and Ocean Technology Provider Organizes Interactive Presentations

What kinds of webinars appeal to the ocean technology community in these extraordinary times? Hydrographic and ocean technology provider Nortek has learnt that interactive digital events with an emphasis on learning and practical examples have a massive appeal. The Norway-based company has recently launched a live webinar series with over 20 classes and interactive presentations. These are tailor-made for people working with ocean technology, such as oceanography, subsea navigation, marine navigation and ocean surveying. The educational webinar series covers everything from real-time data collection near the coast to using acoustic Doppler current profilers (ADCPs) to estimate suspended sediment properly and how to get accurate...

Securing Offshore Oil and Gas Infrastructure with USVs

Employing commercial-off-the-shelf USVs that can be rapidly reconfigured with a diverse range of sensors can enhance the ability to deliver energy to America and the world. This is a win-win for the energy industry, says George Caldorisi when he describes the securing of oil and gas infrastructure with Unmanned Surface Vehicles. While the exigencies of climate change have led to major strides in the development and deployment of renewable energy sources such as solar, wind and others, the world’s energy needs will continue to be met primarily by oil and natural gas for the foreseeable future. As readers of Hydro International are well aware, the strategic implications of the United States’ transition from energy dependence to energy independence to becoming a net oil and gas exporter are being felt worldwide. While some saw this sea change coming, most did not, and the community of nations is still coming to grips with... (read more)

Hydrographic and Geophysical Surveys in Celtic Sea and Atlantic Ocean

Hydrographic and geophysical survey operations will be undertaken by INFOMAR in the Celtic Sea and the Atlantic Ocean between April and October this year, according to a recent marine notice from the Irish Department of Transport, Tourism and Sport. INFOMAR is a joint programme between Geological Survey Ireland and the Marine Institute, surveying unmapped marine territory and creating a range of integrated mapping products of the physical, chemical and biological features of the seabed. Covering some 125,000 sq. km of underwater territory, INFOMAR will produce integrated mapping products covering the physical, chemical and biological features of the seabed. Both Irish Marine Institute vessels,... (read more)

UTEC Completes Survey Subcontract for McDermott in the Middle East

UTEC, a global surveying company in the Acteon subsea services group, completed consecutive as-built and post-construction anchor debris clearance surveys using remotely operated vehicles (ROV) for McDermott International. The company mobilized a DP2 offshore support vessel in early December 2019 with work- and observation-class ROVs and a nearshore survey workboat for the as-built campaign. The anchor debris clearance campaign used the same vessel with a sub-bottom profiler, a side-scan sonar, a multibeam echosounder and a magnetometer. Geophysical Survey in Shallow Waters  “We are delighted to have completed these surveys,” said Nadir Rahmatullah, UTEC commercial director for Asia Pacific and the Middle East.... (read more)

A view of hydrographic technology and the market for 2020
In the last decade, there has been a steady march towards the automation of hydrographic data collection. Jim Gardiner, a research scientist at Valeport, views the technical and commercial challenges in hydrographic operations. In the last decade, there has been a steady march towards the automation of hydrographic data collection. Jim Gardiner, a research scientist at Valeport, views the technical and commercial challenges in hydrographic operations. In terms of multibeam technology, we’ve seen continual advancements from the main players such as Teledyne Reson, Kongsberg, R2Sonic and the emergence of Norbit. Alongside this, there has been a steady improvement in GPS, inertial positioning systems and acquisition/processing software. As the capability of these systems has improved, it has placed a focus on the importance of accurate and reliable sound velocity data. To achieve accurate bathymetry,... (read more)
