AUV Tracking System Tested in Loch Ness

A collaborative research project called Autonomous Surface and Sub-surface Survey System (ASSSS) aims to deliver an integrated system to provide a means of conducting low cost, shore based, full water column marine surveys using multiple unmanned systems. The project, part funded by Innovate UK, hopes to encourage wider adoption of unmanned systems.The project is being led by a U.K. based developer of unmanned and autonomous marine systems, ASV Global. It combines the advantages of autonomous underwater vehicles (AUVs) and autonomous surface vehicles (ASVs) to further data gathering opportunities.

Reducing Aquaculture Die-offs in Real-time

In 2017, Atlantic Sapphire lost 250 tonnes of salmon in a mass die-off due to hydrogen sulfide poisoning from accumulated organic matter, an all-too-common problem in aquaculture with significant economic losses.Growing salmon in land-based tanks in which water is continuously circulated (Recirculating Aquaculture Systems, RAS) means low waste discharge and high-levels of water re-use, but also sporadic toxic microorganism outbreaks that cause costly mass fish stock die-offs.FluoRAS, Horizon 2020 COLUMBUS and  EMFF ECO-AQUA are putting in place aquaculture trials of a fluorometer sensor system

MG3 & Satellite Derived Bathymetry

Operation of marine survey vessels in shallow-water coastal environments is a dangerous endeavor. A subsurface obstruction can tear a multi-beam sonar from its tow cable, resulting in loss of the expensive device and potential delay in the expedition. Lost equipment, however, is a minor inconvenience compared to the equally real possibility of the ship running aground in poorly charted waters, endangering the safety of its crew and incurring millions of dollars in damage.For this reason, survey vessel operators invest considerable time and money to minimize the risk involved in each voyage. They are

Self-compensating Magnetometer for Gavia AUV

SCM will still work as the compensation coefficients are calculated at the beginning of each mission.”OFG said its SCM systems are being used for AUVs around world on various applications ranging from geological mapping, mine-countermeasures, and vessel signatures, to unexploded ordnance (UXO) and marine archaeology.Equipping the Gavia with the OFG SCM system for AUVs enables the collection of real-time compensated data that removes the magnetic signature of the AUV ensuring that the ambient field is being measured rather than the AUV itself. Combining the compensated three-vector magnetic data of

InterMoor Unveils New Acoustic Release Mooring Connectors

other connectors on the market can only disengage at a portion of their load rating.The new device was designed using the proven platform of sister company SRP’s Rocksteady mooring connector and its secondary actuated release system, with a control system developed in conjunction with Teledyne Marine. The advanced control system uses military-grade, high-fidelity Teledyne Benthos acoustic modems, and implements domain key authorization, unique addressing, network relay and frequency hopping techniques, ensuring the mooring connectors are never affected by obstructions or conflicting noise.The

stem to stern, throughout all five of its decks. It received new cleaner and more efficient diesel engines, the latest navigation and ship-positioning systems, as well as sophisticated sonar, allowing it to map the ocean floor in sharper detail and even differentiate between species of fish and other marine life.The Thompson's laboratories were updated to include advanced IT infrastructure to better support scientific data collection and analysis at sea, while also enabling improved real-time communications with shore. Several critical sensor systems also were replaced, providing upgraded scientific

stable but maneuverable mini ROV on the market. Since this kit has been in the works since before the BlueROV2 was launched, every ROV in the wild already has the necessary mounting holes for the upgrade. Kits are $599 and are shipping with a two week lead time.(As published in the April 2018 edition of Marine Technology Reporter

University of Limerick Buys ROV for Renewables Research

for the offshore renewables industry. The ROV is equipped to a high specification with precision positioning and navigation systems, camera and lighting systems and sonars. The systems will be used as a test bed for research to develop capabilities for inspection, maintenance and repair work on Marine Renewable Energy (MRE) infrastructure in the challenging strong wave and current conditions at MRE test-sites and offshore MRE sites in Ireland and further afield. The ROV system is home ported at Limerick Docks in the Republic of Ireland.University of Limerick President, Dr. Des Fitzgerald, stated
