Stealthy Submarine Concept Unveiled

include improved stealthiness and endurance. The SMX31E's biomimetic shape and the skin material making it stealthier against active sonar emissions, while high energy capacities and efficient energy management system allow the crew to be submerged for months.Using advanced artificial intelligence technology, this submarine offers maximal connectivity to interact with the rest of the fleet in a distributed underwater network. This new IT design enables the crew to collect and process data efficiently with remote sensors allowing them to master underwater tactical situation.Technical characteristics

large dose of data analytics. Its inspection tool uses electrical tomography and digital signal processing to measure conductivity and permeability values within a pipeline. These are then analyzed to determine the content – fluid and solid – of pipelines or vessels, such as separators.The technology has had the backing of Shell, who are trialling the Deposition In-Line Inspection (DILI) in a 12 in. water pipeline in Brunei in October to detect wax deposits. Planned this December, Rocsole also has a trial set up with Equinor, to inspect the 115 km-long Oseberg pipeline 28 in. export pipeline

to the operators, thus removing the need for acoustic positioning systems and costly mother vessels.Per the project participants, the markers are resistant to marine growth and erosion. Thus they will remain visible to divers and subsea drones throughout the project’s lifespan,“This technology had already proven itself on large structures in the field,” said Jean-Guillaume Besse, Vallourec R&D project leader. “Back in January of this year, we did a first sea trial on much smaller surfaces – down to pipes of 6” in diameter – in the South of France.

In addition to nautical charting, RAMMS has supported offshore wind, coastal management and sea-level rise projects, in line with Fugro’s strategy of expanding into new growth markets related to energy transition and climate impact mitigation. For Lake Huron, the innovative technology will enable efficient and accurate data acquisition, despite multiple site-related challenges, including extensive areas of shallow water, complex coastlines, and relatively sparse coastal infrastructure.“The system’s unique design delivers high resolution data and penetrates to water

With state-of-the-art technology they will investigate the dramatic changes in the polar oceans,” said BAS Director, Professor Dame Jane Francis. “This exciting moment marks a major milestone in the construction as so many people have worked tirelessly over the last four years to bring our new ship to fruition.

The project, launched in 2017, builds on the earlier SeaXerocks system and leverages advances in lighting and higher resolution detector technology to enable 3D imaging capable of mapping the seafloor at millimetric-scale, from up to 10 m altitudes. This enables increased area coverage and safer altitude operation from significantly faster-moving AUVs, potentially enabling data gathering at significantly faster rates than existing technologies

New Lidar Tech Approved for Use by SGRE for Wind Turbine Testing

Siemens Gamesa recently tested a new technology together with ZX Lidars, and based on the results both on the medium range and long range measurements, Siemens Gamesa Renewable Energy (SGRE) approves the use of the nacelle-based Continuous Wave scanning Lidar ‘ZX TM’ from Lidar OEM ZX Lidars for Power Performance Testing.In addition, operational ‘rotor equivalent’ power curves can also be measured with ZX TM’s 50 points around the full rotor swept area, particularly important for turbines with larger rotor diameters offshore and on onshore sites with complex veer or shear

Now that ORV 1 has passed its Sea Acceptance Test (SAT) with flying colours, researchers from the country’s national university can reap the benefits of a highly advanced level of technology that includes no less than three MacArtney MERMAC LARS systems.“Of course, we encountered difficult situations and problems. Whenever this happened, I think of what a Danish engineer, Steen, said to me – ‘Not a problem, always a challenge,’” said Mr Liang Hong-yu,

Offshore Equipment Hydraulic Maintenance Tip-of-the-Day: Fluid Selection

plays a critical role in machine life, and it is easy to take the convenient path, which is use what is already available from other equipment. When matched with the right component, the right fluid will promote uptime, or induce failures and unplanned outages. Understanding the type of hydraulic technology, in conjunction with the proper fluid, will extend life and ensure full efficiency is achieved.Learn more about the importance of offshore equipment hydraulic maintenance during a free webinar entitled: “5 Easy Ways to Ruin Your Offshore Equipment: Lessons Learned in Hydraulic Maintenance
