, or on the seafloor, it provides a measure of the water current. Alternatively, when mounted in a moving platform such as an undersea vehicle the instrument can measure motion relative to the water, or the seafloor. This is known as a Doppler velocity log (DVL). The first patents on the most capable broadband ADCPs were issued in 1997. This capability unleashed the modern era of current measurement. In the decades since, oceanographers and ocean engineers have employed these tools in a variety of configurations and thousands have been delivered. But what have the last few years brought to the field

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.

Knifefish is a critical element of the LCS Mine Countermeasure Mission Package and will reduce risk to Navy personnel and equipment.The Knifefish system, which consists of two unmanned undersea vehicles along with support systems and equipment, uses cutting-edge low-frequency broadband sonar and automated target recognition software technology developed by the Naval Research Laboratory and successfully transitioned to industry. It acts as an off-board sensor while the host ship stays outside the mine field boundaries.Knifefish’s common open systems architecture design and

. “E-ROV is a resident, battery-powered ROV that will go subsea with a surface buoy. It’s a work class electric vehicle with a hydraulic power pack to support its manipulator functions, and it is controlled remotely from our onshore mission support center with communications via the 4G broadband network, using a self-deployed surface buoy,” said McDonald. “We believe (E-ROV) is a significant technological advancement to the next stage of subsea ROV residency. Our next generation of vehicle (the Freedom ROV) will be supported by a docking station at seabed and will have a hybrid

Shearwater Kicks Off Survey for KrisEnergy

upstream oil and gas company KrisEnergy announced the commencement of a 1,200-square-kilometer 3D seismic survey in the offshore Cambodia Block A concession, where the company is developing the Apsara oil field.Shearwater Geoservices' Singapore subsidiary was awarded the turnkey broadband seismic contract, and it has deployed the vessel SW Vespucci for the project.Around 200 square kilometers of the 3D program will be acquired over the Apsara development area to improve imaging of geological faults and sand bodies to aid in the finalization of the design of well trajectories ahead
