Sercel Launches New Ocean Bottom Node

CGG's equipment business Sercel has launched GPR, a new ocean bottom node (OBN) jointly developed in partnership with BGP and designed to leverage Sercel’s QuietSeis broadband digital sensor technology for reservoir characterization and field development efforts.Sercel and BGP have drawn on their longstanding partnership and complementary seismic expertise and experience to design, develop and deploy GPR. The new node has successfully completed sea trials, and input from BGP from the field has ensured GPR’s performance is precisely tailored to meet today’s industry requirements.

Valeport Sensor Technology for Freedom ROV/AUV

Valeport sensor technology has been selected by Oceaneering International for integration into its subsea Freedom vehicles.  Oceaneering’s next generation hybrid ROV, Freedom, will be fitted with Valeport Bathypack, Altimeter and Hyperion Fluorometer sensors.Having previously supplied many sensors and probes for Oceaneering's ROV ranges, hydrographic and oceanographic instrument designer Valeport worked closely with the company's engineering team to meet challenges in communication and connector requirements. The Valeport sensors in the Midas Bathypack were ethernet enabled to offer

Offshore Survey Vessels: Ready for Faster Sensors

, why take more? The value prop isn’t yet there for mid and offshore surveys.If we’re serious about increasing productivity, there must be a fundamental shift in the overall methodology - one that considers the full spectrum of technical advantages associated with vessel designs, sensor technology, autonomous platforms, power density and machine learning. I’m positive AI and blockchain methodologies fit in there somewhere. When we tackle this problem at LeeWay, we start with three fundamental realities:1.Collecting geophysical data requires a physical object (ship, satellite, AUV


DNVGL: New Mooring Line Solution for Offshore Ops

and costly to maintain, and field experience suggests that they can be prone to failure within the first few years of installation.DNV GL’s Smart Mooring solution can be used instead of replacing failed sensors in brownfield offshore operations, or as a complete alternative to implementing sensor technology in greenfield offshore oil and gas developments.  DNV GL’s experts developed the Smart Mooring solution by training a machine learning model to interpret the response of a vessel’s mooring system to a set of environmental conditions and are then able to determine which mooring

Partners Designing Autonomous Seismic Nodes

Underwater sensor technology company Sonardyne International said it is partnering with Shell Brasil and Brazilian research institute Senai-Cimatec to develop autonomous technology to make the monitoring of Brazil’s deepwater pre-salt oil fields more efficient.The new 4D seismic monitoring system, based on so-called On Demand Ocean Bottom Nodes, is being developed under a National Agency of Petroleum, Natural Gas and Biofuels (ANP) promoted program.According to Sonardyne, the goal is to increase the autonomy of ocean bottom nodes and enable them to be deployed and remain on the seafloor for up

Subsea State? Steady with Waves of Optimism

versus value.Our approach to innovation is key to remaining competitive and ensuring that the costs we’ve managed to get down, stay down without any further erosion of margins. Digitalization is a major factor in this, particularly in areas such as remote operations, condition monitoring, sensor technology, visualization, analytics and robotics.In a nutshell, subsea is about putting things in the underwater environment and making them work. We do this exceptionally well and our ingenuity is world-renowned. We’re already doing some of it digitally but must develop the next wave of digital

This time the survey incorporated the use of methane sensor technology, which have been used on AUVs, but not on underwater gliders before, to give greater detail about the hydrocarbons detected. The Franatech laser methane sensor “high-grades” the information gathered, says Lind. An oxygen sensor was also added.During the 14-day Yampi project, again
