Petrobas Awards Fugro Four Multi-Year Contracts
Petrobras has announced tender results awarding Fugro four significant multi-year contracts for the inspection and monitoring of critical subsea infrastructure in Brazil. The contracts, once signed, will commence in the fourth quarter of 2025 and span four years with potential one-year extensions. Each of the four day-rate contracts is assigned to a dedicated vessel—two operated by Fugro and two by partner companies—all of which will be equipped with Fugro’s state-of-the-art remotely operated vehicles (ROVs) for comprehensive and precise inspection and monitoring of subsea assets.
Global Underwater Hub: MoD Must Engage With UK Subsea Industry to Bolster Defense Assets
The Ministry of Defence (MoD) must engage with the UK’s underwater sector to ensure the country is prepared for a potentially “existential” attack on national subsea infrastructure, says Global Underwater Hub (GUH), the leading trade and industry body for the country’s USD$12.24 billion (£9 billion) subsea sector.The call comes following the publication of the UK government’s 2025 Strategic Defence Review. GUH says that the MoD’s outdated procurement mechanisms are being outrun by the rapidly evolving nature of threats facing the country.“Instead of
Norwegian Firms Form Subsea Distribution Alliance
Norwegian firms HTS Dynamics, Connector Subsea Solutions, and TESS Subsea have launched the Subsea Distribution Alliance, targeting complete control and unmatched performance across the entire subsea distribution value chain.The Subsea Distribution Alliance is built to keep subsea infrastructure flowing – from design to delivery.By uniting the product ownership of Connector Subsea Solutions, the manufacturing capabilities of HTS Dynamics, and the distribution expertise of TESS Subsea, the alliance will offer complete subsea solutions through one, streamlined partnership.Collectively, the members

still provide the necessary human and technical capacity for complex, remote missions.”One recent voyage in the Mediterranean, for example, focused on seismic activity and gravity waves within an underwater volcanic caldera. Such missions are crucial for monitoring geohazards that threaten subsea infrastructure, including the world’s expanding network of critical data cables. Another expedition in the mid-Atlantic examined the mechanisms by which carbon is sequestered into the deep ocean—a key process in understanding and mitigating global climate change.“These are not academic
NOC: Natural Disasters Responsible for 25% of Subsea Cable Damage
said Dr. Isobel Yeo, a researcher at NOC and co-lead on the project. “With climate change driving more extreme weather, rising sea levels and sediment-laden river discharges, the frequency and severity of these hazards are expected to grow, amplifying the challenges of maintaining resilient subsea infrastructure.”The vulnerabilities were starkly illustrated by the 2022 Hunga Volcano eruption in Tonga. Underwater density currents generated by the eruption destroyed Tonga’s sole international cable, isolating the nation for weeks and severely hindering emergency response efforts.Similarly
