MTS Appoints Dr. Josh Kohut as VP

Irene. Josh’s glider was used to identify the previously unrecognized rapid mixing and extreme cooling response of the coastal ocean that then fed back on Irene’s intensity.The discovery was published in Nature Communications and was fundamental to establishing the US Hurricane Glider Sentinel Program in 2018.Since 2010, Josh has been an author on nine peer-reviewed publications in the MTS Journal. He has been the faculty advisor to the Rutgers MTS student section since 2013 and is the founding Director of the MTS Glider Technology Camp at Rutgers.Kohut will take over the position of

Sonardyne Demos New Tech at ANTX

Sonardyne Inc. will present its advanced unmanned underwater vehicle (UUV) tracking results at the Advanced Naval Technology Exercise (ANTX) this week in Newport, RI.The event’s attendees will be shown the results of recent trials which tested Sonardyne’s Sentinel Intruder Detection Sonar (IDS) against elite US Navy divers and small UUVs. Specifically, the strength of Sentinel IDS’ combined active and passive intruder detection sonar for ship and harbor security, against even the smallest UUVs, will be demonstrated.  Since its introduction, Sentinel has been used in critical

regarded choice for positioning, tracking and autonomous monitoring applications. New ‘plus’ hardware, supported by Wideband 3 digital signal architecture, further strengthens the investment case.Increasingly, Sonardyne is helping ocean space users to monitor and protect their assets. With Sentinel, underwater intruder detection is provided, while Sentry is helping operators to detect oil or gas seeps from subsea assets and reservoirs. Sentry can also spot leaks from emergent CO2 storage sites. Meanwhile, Sonardyne’s Solstice multi-aperture sonar also offers high definition imaging mission

must be inspected; however, this is neither continuous nor frequent, and there is currently no obligation to inspect abandoned wells. In both cases, industry lacks a standard approach at this stage in a well’s lifecycle to integrity monitoring and environmental liability.The new project involving Sentinel Subsea, Heriot-Watt University and the Oil & Gas Innovation Center will address this challenge by building upon a concept conceived by Sentinel Subsea to develop an environmentally benign tracer compound (known as SWIFT), that will be pumped into a well before it is sealed. If the well leaks

Revolutionizing Decom Environmental Monitoring

Sentinel Subsea has created a new well integrity monitoring system, has had its technology tipped to become ubiquitous within the global decommissioning industry.Long-term well integrity verification specialist, Sentinel Subsea – which is being supported to accelerate its commercialization by the Scottish Enterprise High Growth Ventures team – also announced it is working toward its first offshore field trials with a large independent U.K. operator.Taking place during Q2 2019, the trials will see deployment of the technology in the North Sea.
