the smarts it’s been developing for the Sabertooth for new electric vehicles.Another firm looking to enter the resident vehicle space is UK-based subsea machinery firm SMD. During Offshore Europe, it launched its Quantum EV ROV. While the Quantum EV ROV made the headlines, what SMD launched was a technology suite, rather than a single ROV, based on an open-electric framework for whatever shape vehicle is required and that can be adapted for a variety of tethered or untethered operations.Mark Collins, SMD’s Director for Remote and Autonomous Technologies, says four years’ work has gone

years. Microfluidic systems require less power, reagent, time, and human involvement than conventional instruments, making them ideal for long term deployments. These concepts are being employed to eDNA by the Sieben Lab at Dalhousie University in Nova Scotia. Their "Inlaid Optical Celltm" technology is a patent-pending approach that enables miniaturized optical spectroscopy on ultra-small amounts of fluid, less than a few microliters. Conserving reagent usage per measurement minimizes the volume of onboard chemicals and waste storage leading to smaller sensors.  These inlaid cells are

, we can now offer a comprehensive suite of autonomous underwater vehicle systems that address our customers’ needs. While this is a perfect complement to our existing UUV business, more importantly, it brings together brilliant and talented people who are at the leading edge of unmanned systems technology.”Duane Fotheringham, who previously served as Hydroid’s president and chairman of the board, will serve as president of Unmanned Systems, reporting to Green. Fotheringham joined Hydroid in 2008 as the vice president of operations and was responsible for the research and development

center, says it started with a group interest in microbial oceanography – the study of the smallest organisms in the ocean, including understanding how and why harmful algae blooms form. Dr Birch spoke about the work and its results at the National Oceanography Centre’s Marine Autonomy and Technology Showcase (MATS) event in Southampton, late last year. The result is an Environmental Sample Processor (ESP), a compact robotic system that filters a water sample and then processes the biomass to create analysable samples.A long-range autonomous underwater vehicle carrying an ESP is recovered to

Unique Group Signs Exclusive Agreement with OTAQ Offshore

Unique Group has signed an exclusive rental agreement with UK-based OTAQ Offshore to represent the latter’s technology and products across the Middle East, APAC and the Americas.  The agreement will see Unique Group represent a number of industry-renowned technologies, including the OceanSENSE and DragonFish solutions. Deployed in the dual roles of subsea leak and cement returns detection, OceanSENSE is recognized as the industry standard and has been deployed successfully on over 1000 offshore projects globally. Proven to work efficiently in the offshore environment, the DragonFish’s

Ransomware: The IT Danger on the Horizon

have loosely heard of it, but the broader implications haven’t yet penetrated the public consciousness. In different industries, that general lack of awareness could be a big problem—and the maritime sector is a good example.Ransomware hits at the confluence of two critical trends in modern technology: the ever-increasing integration of IT systems into daily life, and the interconnectedness of those IT systems. In its 2019 report “Evasive Threats, Pervasive Effects,”  Trend Micro recorded a 77% uptick in ransomware attacks between the second half of 2018 and the first half of

Copenhagen Subsea Debuts the Gorilla ROV

Copenhagen Subsea launched a new powerful Remotely Operated Vehicle (ROV), specifically developed for the offshore industry. The ROV is based on Copenhagen Subsea’s rim-driven thruster technology and is designed to be robust and reliable in challenging environments – qualities which inspired us to name it the Gorilla.In fact, reliability has been first and foremost throughout the design and development of the Gorilla. By basing the ROV on industrial components, Copenhagen Subsea was seeking to ensue the utmost operational reliability.The Gorilla is equipped as standard with an intelligent
