Iridium: The Audacious SatComm Network That (Almost) Couldn't
An audacious satellite communications program launched, nearly failed, and eventually found its orbit, albeit with government help.
Drone Monitoring of Ship Emissions to Begin in EU
Martek's drones will sample gases from vessels' emission plumes using electro-optical, infrared imaging, gas emission and automatic identification system sensors.
Submersible Speedboat Geared to Offshore Inspections
Scubacraft uses proprietary technology that allows it to transform its buoyancy from a floating craft into a streamlined submersible.
Offshore Oil Industry Faces "Perfect Storm"
Increasingly stringent decommissioning regulations are coming into force at the same time that the inventory of structures nearing end-of-life status is getting larger and more complex.
Autonomous Wave Glider Monitors Volcanic Activity
The wave glider consists of a float above water connected by a 5.8m umbilical cable to an underwater glider that propels the vessel.
Irradiation System Kills Invasive Species in Ballast Water
Ballast water may pose serious ecological, economic and health problems due to the marine species it carries.
Digitizing the Global Supply Chain
Few dispute the idea that digital technology can modernize shipping ports and the global supply chain. However, stakeholders first may have to clear some fundamental obstacles.
Grid-Connected In-Stream Tidal Turbine Deployed in Canada
The turbine harnesses only a fraction of the energy potential of the Minas Basin, where the mean spring tidal range is 14.5 meters.
Sulfur Regulations Challenge Refiners and Shipowners
The new limits will affect the largest portion of the approximately 3.9 million barrels per day of global marine fuel use.
New Mic Could Bolster SONAR Applications
Many existing underwater microphones are made from ceramics, which generally absorb and register only about 20% of the low-frequency acoustic waves traveling through water.
Acoustic Buoy Helps Ships Avoid Whales
This new technology can help ships avoid lethal encounters with whales.
Marine Pumped Storage System Undergoes Testing
Pumped storage power plants installed on the seabed can use the high water pressure in very deep water to store electrical energy with the aid of hollow spheres.
Bio-Derived Glue Holds Together Underwater
Mussels secrete a combination of natural liquid superglues and stretchy fibers, called byssal threads, that adhere equally well in saltwater and freshwater.
Significant Economic Losses if River Locks Fail
Barge transportation is of great importance to U.S. agriculture because of its comparatively low transport costs compared to overland modes.
Surfaces Repel Both Water in Oil and Oil in Water
To date, the ability to repel water when covered by oil, and oil when covered by water, has been regarded as contradictory.
Unmanned, Automated Utility Ship to Be Built in 2017
The ship will initially be remotely piloted but will transition to fully automated and ultimately autonomous operations after control algorithms have been developed during the remote piloting phase.
Cyber Security at Marine Ports Is Addressed
Maritime bulk liquid transfers increasingly rely on computers to operate valves and pumps, monitor sensors and perform many other vital safety and security functions.
Drone Launch from AUV Demonstrated
The demonstration showed that an unmanned aircraft, surface vessel and undersea vehicle can communicate and complete a mission cooperatively and autonomously.
"Clever Buoy" Uses Sonar and Software to Warn of Sharks
The system uses multibeam sonar transducers that are mounted on the ocean floor, together with custom detection software, to scan for shark-like objects.
Biomimetic Fin Helps Maimed Sea Turtle
The new flipper design could allow injured turtles to be rehabilitated and live a more normal life.
