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 are 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 hydrographic 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)

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)

Colombian Naval Academy Certifies Category “A” Hydrographers for the First Time

The Colombian Navy has successfully concluded its first category “A” hydrography course. This course, which was recognized by IBSC in 2018, was completed by 15 naval officers at the “Almirante Padilla” Naval Academy (ENAP). This means that the institution is now able to provide hydrography training for personnel in Colombia, to the high standards established by the IHO for the exercise of their role in the national hydrographic service, within the national maritime authority (DIMAR). Previously, personnel received category “A” hydrography training in other countries such as the United States or Chile. The certification ceremony was presided by the Rear... (read more)

Subsea Autonomy is Moving Beyond Waypoints

Underwater an AUV Must Rely Upon its Own Sensor Network
The AUV has been the tool of choice for shallow-water MCM and EOD operations for a number of years. The coverage by popular news channels of unfortunate events, such as the MH370 tragedy, has also shown that the AUV has undisputedly become the tool of choice to carry out salvage operations at extreme depths. The AUV has no physical link to the surface and the majority of missions are still pre-programmed by a human, which can be time consuming and error prone. Missions are normally a sequence of defined waypoints where the AUV may be required to carry out certain... (read more)

Mapping Underwater Terrain with Bathymetric Lidar

Two Similar Projects in Different Parts of the World
High-resolution bathymetric surveys support aquaculture research and increase navigational safety. In a case study, Tim Webster reports how this is done at Cape John Peninsula in Canada. In the second one, Carol Lockhart describes the project in the Kingdom of Tonga, a Polynesian archipelago comprising 169 islands that stretches across approximately 800 kilometres in the South Pacific Ocean. Measuring water depth for nautical purposes dates back to ancient civilisations. As technology has evolved through the centuries, besides ship-based echo-sounding, remote monitoring and mapping of water bodies has become increasingly available via Lidar bathymetric surveys conducted by airborne systems. New coastal... (read more)

Hydrographic Education During a Lockdown

Experiences in the Netherlands
On 12 March, the Dutch government decided to ‘lockdown’ all activities involving multiple persons, including education. That decision immediately affected the hydrographic institutions in the Netherlands. The Netherlands has an active four-year Cat A course in Ocean Technology at the NHL Stenden University of Applied Sciences – Maritime Institute Willem Barentsz (MIWB), and a 3+3 month Cat B course at Skilltrade. Both had to cope with the lockdown in different ways due to their different set-ups and student populations. Organizational Situation After Lockdown Although education is not a ‘contact’ profession in the strict sense (or at least it shouldn’t be),... (read more)
