, fisheries habitat mapping and burial assessment studies. She is also well suited to perform geotechnical sediment and seabed coring/CPT for wind farm and LNG port facilities, pre/post excavation dredging. The Miss Emma McCall encompasses satellite communications (voice, fax, and email), differential GPS, geophysical survey gear and two A-frames with high-speed winches.The Miss Emma McCall was recently mobilized to Mexico to complete two EPOS projects in Mexico for Total in Blk. 2 (Perdido) and Capricorn Energy Mexico (Cairn Energy) in Blk. 9 (Sureste Basin). The Block 2 EPOS program was in deepwater

SBG Systems Unveils New Line of Miniature Inertial Sensors

in heading (0.2°). With its dual-antenna capability, Ellipse-D provides precise heading in a few seconds, in all dynamic conditions, and even in challenging GNSS conditions. It is also immune to magnetic disturbances. Ellipse-D is quad-constellation, meaning it could use simultaneously satellites from GPS, GLONASS, BEIDOU, and GALILEO for more signal availability in challenging navigation conditions.Designed with high quality industrial-grade components, Ellipse inertial sensors are highly tested and calibrated in dynamic and temperature for a consistent and repeatable behavior in all conditions.

diver/UUV would continue to move into the controlled zone, so then the Stingray net would be deployed, on this occasion from the Port Police Patrol boat. AIS transmitters were used to track ‘friendly’ assets. But, because the update rates during the exercise were slow, ION switched to using GPS tracking, where it was available, through some “on the fly” integration.“There was a silty bottom (in the area) and high turbidity,” said Gentle, “the conditions were challenging. But the system detected real and dummy divers. Atlas Elektronik’s SeaFox was used

VIDEO: Drone Inspects FPSO Tank. It Could Soon Do It On Its Own

modeling and prediction systems, forecasting the ocean’s behavior and currents, and used the TRAPS algorithm to map out strongly attracting regions over the course of the experiment. The researchers let the objects drift freely with the currents for a few hours, and recorded their positions via GPS trackers, before retrieving the objects at the end of the day.“With the GPS trackers, we could see where everything was going, in real-time,” Peacock says. “So we laid out this initial, widespread pattern of the drifters, and saw that, in the end, they converged on these traps.&rdquo

New Drifter Buoy Tracks Water Currents

MetOcean Telematics has developed the STOKES Iridium tracking drifter, a compact drifting buoy designed and tested in technical partnership with Florida State University (FSU) that tracks water currents at the surface.The small light-weight buoy is equipped with Iridium satellite telemetry, GPS positioning and a sea surface temperature sensor. Iridium satellite telemetry enables the buoy to provide vital sensor and geo-positional location data in real time. Iridium also allows the buoy to have bi-directional capabilities. This is a critical ability, for example, if the buoy enters a region of interest
