Unmanned Marine Systems, Squared

Unmanned platforms and underwater vehicles have been providing new ways for ocean scientists to study the ocean in more detail and over longer periods. What happens if one can deploy the other?The advantages of unmanned systems deploying others are multiple, not least in our expansive oceans. Deploying a glider (down to 1,000m) using a wave-propelled unmanned surface vessel (USV) means data can be gathered together over long periods at far flung locations without the need for a crewed research vessel to deploy either system, which can be hard to get slots on, let alone funding.But then, what if you

MIT Studies Underwater Navigation Powered by Sound

New approach could spark an era of battery-free ocean exploration, with applications ranging from marine conservation to aquaculture.GPS isn’t waterproof. The navigation system depends on radio waves, which break down rapidly in liquids, including seawater. To track undersea objects like drones or whales, researchers rely on acoustic signaling. But devices that generate and send sound usually require batteries — bulky, short-lived batteries that need regular changing. Could we do without them?MIT researchers think so. They’ve built a battery-free pinpointing system dubbed Underwater

Partners Team Up to Develop Utility Class ASV

CSA Ocean Sciences Inc. (CSA) and SeaRobotics Corp. (SRC), both based in Stuart, Fla., are working together to jointly develop the next generation utility class autonomous surface vessel (ASV).Based on the fully integrated SR-Surveyor M1.8 ASV, introduced by SRC in 2019, the new utility class ASV will deploy the same fully integrated control, survey, and autonomy systems, providing the market with a fully compatible line of ASVs that are capable of addressing a wide range of tasks – from 1.8 m inshore/nearshore vessels to over 12 m ocean going vessels.The SR-Utility 3.0 and SR-Surveyor M1.

Submersible Linear Position Sensors for Offshore Drilling

NewTek Sensor Solutions offers new, custom designs of Submersible Linear Position Sensors constructed of special alloys with chemical resistance to water in depths exceeding 15,000 ft or more and with external pressures up to 20,000psi.  NewTek Subsea and Marine Sensor designs are used for measuring the strain on mooring chains that keep ships or platforms stationary and monitoring structural movement and elongation of pipelines, derricks and structural components of an oil platform to a fraction of a microstrain. Position measurements ensure the drilling platform doesn’t shift to more than

The French-based company said its naval architects considered operational needs expressed by its customers seeking to invest in systems that will remain technologically superior over the 30 to 40 years of ships’ lifecycles.On the horizon of 2040, in a context of permanent surveillance of oceans, navies will have to navigate in increasingly complex environments. The objectives for submariners will be to operate freely, to share information safely and to be able to act firmly and swiftly, Naval Group expects.With these considerations in mind, the SMX31E has been engineered as a stealthier

Pipeline Inspection with Fast(ER) Results

Finland’s Rocsole is hoping to provide operators with better, faster insight into their pipelines through a new compact inline sensor and a large dose of data analytics. Its inspection tool uses electrical tomography and digital signal processing to measure conductivity and permeability values within a pipeline. These are then analyzed to determine the content – fluid and solid – of pipelines or vessels, such as separators.The technology has had the backing of Shell, who are trialling the Deposition In-Line Inspection (DILI) in a 12 in. water pipeline in Brunei in October to detect
