NextGeo Concludes Tyrrhenian Link's East Section Survey for Prysmian
all the pre-installation survey tasks for the Tyrrhenian Link East branch on behalf of Prysmian.The works entailed extensive marine detailed geophysical, geotechnical, UXO, archaeological and environmental survey activities along the Terna’s submarine power line connecting the landing points in Sicily and in Campania with two HVDC cables, approximately 485 kilometres long each.Additional survey tasks have been executed in the nearshore sections of the corridor, including boreholes, HDD survey, topography and geoelectrical investigations.Over 400 days of work and numerous ships were used to carry
Italy's TSO Tests Subsea Drone for Marine Geophysical Surveys
Development Director.Italy’s ten-year National Grid Development Plan outlines a significant increase in investment in subsea cables infrastructure, to develop a more efficient and reliable grid.The plan includes large subsea infrastructure projects like the Tyrrhenian Link - connecting Campania, Sicily and Sardinia - the Adriatic Link, between the Italian regions of Marche and Abruzzo - and Elmed, the energy bridge between Italy and Tunisia
Survey Work Starts for Trio of Planned Med Floating Wind Farms
below the surface of the seabed. It will then use its Deepwater Drilling system to collect borehole samples for laboratory testing. Work will take place in water depths of up to 1,600 meters – nearly one mile deep. Building on its ongoing success with another project launched off the coast of Sicily in 2022, Seas will partner with Italian company Argo on a vessel to serve as its base of operations
Renexia, Seas Geosciences Ink Seabed Exploration Deal
turbines at Med Wind, a floating offshore wind farm project in the Mediterranean.Seas will deploy its robotic seafloor drill and cone penetration testing up to 40 meters below the seafloor, in water more than 900 meters deep, to acquire geotechnical information about geohazards at the project site in the Sicily Channel. The work will enable Renexia to define and design the most appropriate seabed anchoring systems for the turbines and ensure maximum attention to the surrounding ecosystem.Med Wind will be built gradually in stages, reaching a full installation of up to 190 turbines capable of generating
Eni Installs "World's First" Inertial Sea Wave Energy Converter Offshore Pantelleria
Italian energy firm Eni said Tuesday it had installed the world's first Inertial Sea Wave Energy Converter (ISWEC) device connected to the electricity grid of an island.The ISWEC is located about 800 meters off the coast of Pantelleria island, in the Strait of Sicily in the Mediterranean Sea, and can reach 260 kilowatts of peak power generation converted from wave energy. "This experimental campaign, conducted under real operating conditions, will lead to useful results for developing the second-generation device currently under study," Eni said.ISWEC was developed by Eni in collabora
Alcatel Submarine Network’s DC/FO Tech together with Equinor ASA wins the 2022 UTC Award
the Barents Sea. Since deployment at Johan Castberg, the technology has also been chosen for several more field developments and projects, including the Breidablikk subsea field development and the Northern Lights CCS project.It is also helping to supporting ocean science, as part of the IDMAR project in Sicily in a 3,500 m deep deployment. Equinor has patent in subsea well concept solutions applying the DC/FO technology.The prize, which is designed to recognize, celebrate and showcase the many outstanding achievements within the global subsea industry, was awarded to joint winners ASN and technology co-develope
Subsea Vehicles: Diving into the Autosub Program
Marine Laboratory (now the Scottish Association of Marine Science), Autosub-1 started doing the science missions it was built for, including herring stock assessments in the North Sea using a fish finding echo sounder, leading to krill assessment work in Antarctica, and a project in the Strait of Sicily, where Autosub-1 got stuck under a ledge and required the help of an ROV to be dislodged.Autosub-2 – a major rebuild of Autosub-1 was launched in 2000. It saw the initial vehicle’s lead-acid car batteries changed out for 5000 D-cells in carbon fiber tubes, helping to extend Autosub-2&rsquo
Ancient Shipwreck Supports Diversity of Underwater Life
researchers report finding an amazing community of 114 species of invertebrates on priceless archeological artifact, including ecological ‘constructors’, ‘binders’, and ‘dwellers’On March 10, 241 BCE, a sea battle took place near the Aegadian Islands off northwestern Sicily. A fleet equipped by the Roman Republic destroyed a fleet from Carthage, ending the First Punic War in Rome’s favor. But scientists have now shown that this destruction and carnage utimately made a a rich flowering of marine life possible.In a recent study in Frontiers in Marine Science, they
MacArtney, INFN to Test Underwater Connectors
MacArtney to supply and test several underwater connectors for INFN - the National Institute for Nuclear Physics.INFN for the IDMAR Research Infrastructure in Sicily supports, among others, the KM3NeT (Cubic Kilometre Neutrino Telescope) infrastructure in the Mediterranean Sea. MacArtney Underwater Technology will be working with INFN for the duration of a system solution project to provide junction box mechanical frames and pressure vessels designed to host OPAs (Optical and Power Assemblies) for the connection of neutrino detection units from the seabed.Connected from the shore station by approximatel
