Italian transmission system operator Terna has launched the Gavia autonomous underwater vehicle (AUV) as part of a partnership with US startup Terradepth. The program aims to advance marine geophysical surveys to facilitate the development and safety of seabed infrastructure. Terna technicians tested the performance of the Gavia drone while conducting geophysical surveys near Casamicciola Terme. The partnership can test innovative technologies, such as subsea drones, which can complement traditional subsea inspection tools. Italy's National Grid development plan includes large-scale submarine infrastructure projects.
Marlink has upgraded its smart hybrid VSAT installation on PGS Ramform Hyperion to provide higher uplink speeds for offshore geophysical data transmission. The upgrade allows for GEO VSAT in excess of 250 Mbps, enabling instant data transfer from the ship to its landside headquarters. The upgrade reflects the high value of survey 3D, high-density 3D or 4D seafloor imaging generated by the vessel. Instant data transfer is transformative for PGS’s ability to quickly move large amounts of seismic data to the cloud.
The U.S. Department of Energy (DOE) has selected 10 ocean energy-related research projects to receive $1.3 million in funding. These projects will gain access to testing expertise, numerical modeling, laboratory testing, tank/tank testing and expertise within the TEAMER facility network. Applications for RFTS 12 are now open and the TEAMER program aims to accelerate the viability of marine renewable energy by providing the best facilities and expertise.
The Viking Link, the world's longest land and submarine power interconnector, is operational and carries electricity between the UK and Denmark. The $2.15 billion project, a joint venture between National Grid and Danish system operator Energinet, will connect Bicker Fen substation in Lincolnshire to Revsing substation in southern Jutland. The line will be able to carry enough electricity for up to 2.5 million British homes, saving British consumers more than £632 million ($500 million) cumulatively over the next decade thanks to cheaper power imported from Denmark. Construction began in 2019 and took more than 4 million man-hours.
TechnipFMC has been awarded a “significant” integrated engineering, procurement, construction and installation (iEPCI) contract by Petrobras for the delivery of the Mero 3 HISEP project in Brazil’s pre-salt fields. The contract covers the design, engineering, fabrication and installation of subsea equipment, including manifolds, pipelines, umbilicals, distribution and field service life. The contract is worth more than $1 billion and complies with research and development guidelines set by Petrobras. TechnipFMC has advanced the qualification of the core technologies required to fully subsea deliver the HISEP process, including gas separation systems and dense gas pumps.
Tracerco has secured a million-dollar contract in the Gulf of Mexico to deploy its pipeline inspection technology Discovery on multiple oil and gas platforms. The project is part of an agreement between three major U.S. oil and gas companies that operate different risers on multiple platforms. Developed using subsea CT scanning technology to provide critical flow assurance and integrity data without coating removal, Discovery is already in use on more than 100 oil and gas assets around the world.
