Edible Aquatic Robot Could Collect Environmental Data
presence of microorganisms, which could be read after collection or via remote sensing.The work is the latest innovation in the burgeoning field of edible robotics and robotic feeding. The Intelligent Systems Laboratory has previously published several papers on edible devices, including edible soft actuators as food and pet food manipulators, edible control circuits and edible conductive ink for crop growth monitoring.“Although the development of miniature swimming robots for natural environments has progressed rapidly, they are typically made from plastics and include batteries and other electronic
Subsea Digitalization: Remote Control
trees at Equinor’s Fram Sør field, offshore Norway. As part of the agreement, future engineering, procurement and construction will be directly awarded to SLB OneSubsea conditional on a final investment decision. The IoT includes three key digitalization efforts: intelligent sensors and actuators on the equipment (rather than spring-operated on/off systems), connectivity through a secure digital platform and the ability to turn data into decisions via analytics and diagnostics.“The industry needs more data to develop a deeper contextual understanding of equipment performance to safely
Interventek to Supply 20,000 psi Open-Water Well Intervention Valves to Trendsetter Engineering
in an HPHT environment would normally use hydraulic gate valves or rams as a well control solution, but these are slower to operate, much larger and much heavier, Interventek explained.The company said that its "unique" shear and seal mechanism uses separate internal components and rotary actuators to reliably shear through a range of wireline or coil tubing conveyance systems and safely seal the wellbore in a single operation. This also allows size and weight reduction of the assembly while delivering an outstanding pressure rating, the company said
Deep-Sea ROV Mounted Niskin Arrays Contribute to Sediment Plume Monitoring
quality sensors to provide real time data and water samples on demand, in addition to feedback on the system status, enabling user to quantify the sediment plume scale and density. The Niskin bottles are fired independently by a new system designed and developed by OSIL, utilizing addressable solenoid actuators.The innovative software-controlled system allows for a seamless interface with the client vehicle carrying the array, while the thin-walled solenoid housings themselves are oil filled, with a pressure compensation system ensuring that they can accommodate the range of changes in pressure and temperature
Hearing the Light: DAS could Revolutionize Subsea Defense
or destruction of subsea infrastructure – DAS could play a role in the detection, identification, and localization of threats. Although currently optimized for low frequency detection, DAS does have the capability to detect high frequency emissions as well, such as those generated by vehicle actuators and thrusters, as well as underwater navigation, imaging, and communication technologies. A 2020 MIT study found that small AUVs generate intense emissions in the 15-24 kHz range, which can be 10-45 decibels above the ambient background noise.† A typical DVL emits at anywhere from 400-600
Tech File: A Robotic Reach in Offshore Wind
– software and hardware at the heart of the system – that takes in the vessel’s six degrees of movement (via an IMU and GNSS), including up to 3m significant wave height. The Neptune system uses dual, high speed CAN networks for rapid data transfer between sensors, controllers and actuators. This enables full motion compensation and station keeping accuracy.The company has developed a full-scale prototype, first tested onshore in 2017, both on a six degree of freedom ship-motion simulator STL has and on land at STL’s research facility in Cowes on the Isle of Wight, using

Nortek, Strategic Robotic Systems, Blueprint Lab merge to form General Oceans AS
(USA), and Blueprint Lab (Australia) have merged to form a common holding company, General Oceans AS. Together, the three companies have almost 200 employees and operate across all major segments of the ocean technology market. Revenues in 2022 are expected to reach $63 million with focus on vehicles, actuators, and sensors.Each company will retain their brand and maintain their own production, engineering, and sales. General Oceans will provide management services from a base in London, facilitating collaboration between the companies while also being responsible for funding new initiatives and providing
