Kongsberg Discovery Announces Echo Sounder Upgrade
the expense and time needed for repeated CTD probes. In addition, improved understanding of sound propagation serves as important input for various acoustic instruments used for water-column object detection.Seabed classification and suspended sediments in water columnThe EK80 is the only calibrated broadband acoustic system that can measure backscatter to provide absolute values across sites and sensor platforms. Serving as a supplement to high-resolution seafloor mapping systems, the EK80 provides valuable information required to classify seafloor composition from acoustic surveys. In addition, recent
Viridien Delivers OBN Solution for North Sea Survey
be deployed on an upcoming seismic survey project in the North Sea.Viriden secured the contract through its Sensing & Monitoring business line, marketed under the Sercel brand, from a major customer, whose name was not disclosed.Sercel GPR nodes feature the QuietSeis MEMS technology, which provides broadband signal sensing capability, fidelity, and ultra-quiet performance, to deliver subsurface imaging.The GPR300 excels in shallow water depths down to 300 meters and has a compact, lightweight design for easy manual handling and simplified deployment and retrieval.“Viridien is totally committed
Kongsberg Discovery Launches HiPOS – HiPAP Positioning Software
essentially splits the workload of Kongsberg Discovery’s HiPAP systems, with the positioning and processing managed onboard the vessel processor, while a client user interface is run remotely over a lower bandwidth VPN connection. The remote connection can be via satellite, 4G, 5G or Maritime broadband radio.The user interface can also be operated directly on the vessel, as in a traditional setup, whilst at the same time having the option for shore-based operators to log in and take over for a shift, or provide expert support.Spencer Collins, Vice President for Sales, Kongsberg Discovery, comments:
The Falmouth Scientific Unveils New Transducers
The Falmouth Scientific announced the release of two new transducers covering bands from 200Hz-2000Hz and 2000Hz-20KHz.The AT-650S-AUV TRIOD Low Frequency (200Hz to +2000Hz) Acoustic Projector. The AT-650S-AUV TRIOD single element projector provides a low frequency broadband sound source for applications including underwater communications, sub-bottom profiling or others in a compact form factor for AUV or other underwater applications. An optional Ultra High Definition Audio Class D Amplifier and Troidal Matching Transformer allows for a line level input powered by 48VDC and as low as 24VDC at a
Kraken Robotics Delivers Minehunting Systems to Royal Danish Navy
in parallel with the MSF-class planned mid-life refit.The Canadian company also integrated the KATFISH system with Saab’s Command and Control (C2) software, providing operators with a seamless experience for mission planning and mission monitoring.The inclusion of Kongsberg’s Maritime Broadband Radio (MBR) enables the complete system to operate remotely, streaming full resolution sonar imagery in real-time at ranges exceeding line of sight.In 2023, Kraken also entered in a seven-year sustainment contract with DALO, with options for two further seven-year extensions, for a total possible
PGS Expands Seismic Survey in Egypt’s West Mediterranean
, expected to enable better understanding of shelfal and transform margin potential at the western extremity of Egypt’s offshore area.EGY24 Nefertiti draws on the expertise of partner the Egyptian Natural Gas Holding Company (EGAS) and the capabilities of PGS’ Ramform fleet and GeoStreamer broadband technology.The survey location is near to the Sidi Barrani-1 well, and target reservoirs in the area are likely to be Sidi Barrani/Alam El Bueib Formation (Barremian age) sandstones and Middle Jurassic Khatatba Formation sandstones within structural traps.The new dataset is relevant for companies
Sercel Extends its OBN Portfolio
CGG announced that Sercel now has a complete portfolio of seabed nodal solutions for all water depths down to 6,000 m to meet growing industry demand for ocean bottom node (OBN) seismic surveys. Based on Sercel’s QuietSeis broadband digital sensor technology, the full OBN portfolio includes the GPR300, the GPR700, the GPR3000 and the MicrOBS.The GPR300 nodal solution was designed for seismic acquisition in shallow water down to 300 meters. Since its launch in 2021, over 50,000 nodes have been deployed in the field.The GPR700 was unveiled this week at the IMAGE 2023 convention in Houston, extending
Harvest, 3D at Depth Team in North Sea Project
;s Harvest Technology Group Limited completed a milestone project in the North Sea, partnering with LiDAR technology provider 3D at Depth to deliver remote metrology services for a global subsea services company. The entire operation was conducted with less than 1Mbs of bandwidth and usedboth 4G (broadband cellular network) and VSAT (two-way satellite) connectivity. “We chose Harvest because the technology provides high-fidelity, two-way audio communications, frame-synchronized video, and optimal bandwidth efficiency. This was essential in providing our remote personnel onshore with the
CGG's Sercel Sells 6000 Seabed Nodes to Sinopec
, the Chinese oil and gas exploration, refining, and distribution company. Over 6,000 nodes will be deployed this month in the Bohai Sea off the east coast of mainland China, CGG said.According to CGG, based on Sercel’s QuietSeis MEMS technology, the GPR300 delivers "unprecedented broadband signal sensing capability and fidelity, and ultra-quiet performance to enable best-in-class subsurface imaging and outperforms conventional OBN equipment. With its compact and lightweight design, the GPR300 is easy to use whatever the deployment mode."Emmanuelle Dubu, Sercel CEO, said: &ldquo
