Autonomous Survey Technology: Cutting the Umbilical
approach optimizes efficiency and coordination in offshore operations.”Ocean Infinity has already entered the offshore wind geotechnical market with its newly developed autonomous cone penetration test (CPT) device, Infinity CPT 250. Last year, for the Ossian wind farm, deep push seabed CPTs, seabed seismic CPTs and vibrocore operations were carried out remotely using over-the-horizon commands sent via a remote-control system.Recent advancements in AI and in low orbit, low latency satellite communications which have greatly enhanced remote control solutions and real-time data transfer have made

metals treatment, surface mount electronics production, a large and flexible manufacturing area and various environmental and functional testing apparatus, all of which are required to turn raw materials into completed nodes.“We have been developing the enabling technologies for semi-permanent seabed seismic and subsidence monitoring nodes for over a decade and are therefore naturally delighted that they will soon be used in the world’s first large scale field wide test.“Our sincere thanks go to our research partners in Shell, Petrobras and SENAI CIMATEC for supporting this program since

mechanisms and an auto-navigation system, the ship can conduct geophysical explorations in oceans, polar regions, and continental shelves, such as marine energy resource analysis and fault examinations.The new vessel can deploy up to eight seismic streamers, each up to 6 kilometres long. It also has seabed seismic exploration and high-resolution 4D monitoring capabilities. It can accommodate 50 crew members and travel up to 36,000 kilometres at 15 knots (28 kilometres per hour), enabling coverage of both poles.According to South Korean Trade, Industry and Energy Vice Minister Namho Choe, efficient utilization
CGG's Sercel Sells 12000 Seabed Nodes to China's BGP
in the Middle East. Impressed by the outstanding performance of the GPR300, the crew expects a further improvement in productivity," Sercel said, without disclosing the financial details of the deal."Now deploying a total of 30,000 GPR300 nodes, the operation is considered the largest seabed seismic exploration project to date," Sercel said.Liu HaiBo, BGP Offshore President, said: “First results have clearly shown the GPR300’s efficiency in the shallow water environment and its added value for high-precision subsurface imaging. For these reasons, it seemed obvious
Sourcing Seismic with Subsea Swarms
, from how the data is gathered to how it’s processed, helping to reduce uncertainty for oil and gas explorers and increase understanding of how reservoirs are performing through field life.Today, seismic streamer spreads cover thousands of square miles, there’s automated cable-based seabed seismic-node deployment and the world’s biggest super computers churn the data.But now one of the latest innovations looks close to hitting the open seas. UK-based Blue Ocean Seismic Services, which only launched in 2019, just before the Coronavirus pandemic struck, has its goal set on commercializing

to complete the qualification programme, which is expected by the end of next year (2020). After that, the company is targeting operations in the sea and it’s looking for pilot projects to perform in 2021.An iDROP in the oceanAnother Norwegian technology firm, iDROP, is planning to disrupt the seabed seismic technology market with its autonomous Oceanid nodes. iDROP’s system is based on individual cylindrical sensor nodes (named after Greek sea nymphs) that are dropfall deployed, using gravity and ballast shift for propulsion and position control, to land at specific pre-planned positions

activity in the deep ocean. Wave Gliders are replacing ships to collect critical seismic data from seabed sensors to provide real time seismic alerts for advance warning of tsunamis. Scripps is taking it one step further to utilize the towing capability of the Wave Glider to place long duration seabed seismic nodes in the deep ocean instead of utilizing large ships for deployment. This greatly reduces the costs and risks are greatly reduced while enabling a new ability to autonomously place and monitor deep ocean seabed sensors. What are some of the critical design tenants for autonomous
Norway, Russia to Swap Seismic Data in Oil Search
, it allows us to achieve a better understanding of the regional geological conditions on both sides of the demarcation line and, not least, of geological structures that span across the line," said NPD assistant director of exploration, Stig-Morten Knutsen. The oil and gas industry uses seabed seismic data to help determine where to drill for petroleum reservoirs. The agreement between the NPD and Russian petroleum authorities (Rosnedra) entails that both countries will exchange about the same volume of data from the Barents Sea. In May, Norway awarded 10 new licences in
