iXBlue Launches ROVINS NANO

On the evening before the opening of OI 2016, iXBlue literally unveiled the ROVINS NANO. This compact unit provides highly accurate positioning at all depths, including for middle water station keeping. ROVINS NANO has been designed for ROV pilots performing maintenance and construction operations. It offers the unbeatable stability and accuracy of the inertial position, outputting true north, roll, pitch and rotation rates. iXBlue also updated the audience on developments within the company. Where the Doppler Velocity Log (DVL) has limitations, especially when operating in middle water, ROVINS NANO is now there to guarantee optimal navigation safety. According to Paul... (read more)

100 Successful SDM System Installations

Seatronics and Norwegian associates RTS have achieved 100 successful global installations with the Subsea Deflection Monitoring system (SDM). The SDM system aims to reduce the risk associated with both large and small installations. The system has an extensive history of successful operations in comparison to newer alternatives in the market. The SDM is a time-saving monitoring solution used for the deployment and installation of subsea structures. Time-stamped data from pressure and attitude sensors are transmitted through an ROV hot stab connection or an acoustic modem. When installing the structure, the operator has full online feedback of its heading and deflection. The... (read more)

iXBlue to Equip Submarine Programme for Swedish Navy

Saab, Sweden, has entered into a seven-year contract with iXBlue to equip the two type A26 next-generation submarines with MARINS units, including fibre-optic gyroscope technology. Scheduled to be operational in 2024, the A26 is a high-tech submarine with proven modular design. The iXBlue MARINS inertial navigation system enables stealth autonomous navigation, providing very accurate heading, roll, pitch, speed and position, under severe GNSS-denied environment. Built by Saab, it is considered today as the world’s most modern submarine program. As the submarine will be specially built to operate submerged for extended periods, with excellent manoeuvrability in all waters, the inertial equipment... (read more)

Louis Dreyfus TravOcean Orders Two Saab Seaeye Leopards

Specialist submarine cable installation company Louis Dreyfus TravOcean, France, has ordered two Saab Seaeye Leopards for touchdown monitoring and support. The pioneering Leopard work vehicle, with its 11 thrusters and iCON intelligent control system, will provide TravOcean with a stable work platform that is unrivalled amongst ROVs – particularly in strong currents. Greater flight stability under variable loads is delivered by the iCON system - including pitch and roll stabilisation – to give stable flight even with large tools and sensors deployed. ICON independently manages each device on the vehicle, including auto redundancy to keep the ROV working even with multiple equipment... (read more)

Rugged FOG-based INS for Demanding Autonomous Applications

KVH Industries, USA, has introduced the GEO-FOG 3D inertial navigation system (INS) offering roll, pitch, and heading accuracies of .05° for demanding applications in unmanned, autonomous, and manned aerial, ground, marine, and subsurface platforms, such as subsea remotely operated vehicles (ROV) or mining systems. The GEO-FOG 3D is based on the company’s high-performance fibre optic gyro (FOG) technology combined with centimetre-level precision RTK GNSS receivers and advanced sensor fusion algorithms. The result is a solution that continuously provides fast, ultra-accurate position, velocity, and attitude measurements that keep applications operating no matter how challenging the conditions. The core inertial sensor for... (read more)

Plymouth University Receives AutoNaut Vessel

Researchers and students at Plymouth University, UK, will be able to use an advanced autonomous wave-propelled surface vessel thanks to a new deal signed with a leading UK designer. MOST (Autonomous Vessels) Ltd, based in West Sussex and Devon, is to provide one of its AutoNaut craft after entering into a licence agreement with the university through its Marine Institute. The licence includes access to a 3.5m pre-production model, designed to be sent out unmanned into the marine environment and used to conduct research. Propulsion by Pitch and Roll AutoNaut comprises a single hull with four moving hydrofoils that harness wave energy as... (read more)

Will Hydrographic Offices Rise to the Challenge Of Precision Navigation?

As the size and capacity of vessels entering our ports continue to increase, mariners are challenged with navigating in increasingly constrained spaces. Mariners are demanding more accurate and higher resolution data as ports push the limits of their sea room to compete for megacarriers. This demand creates an opportunity for Hydrographic Offices to provide new products for precision navigation. The demand calls out for the standardisation of data formats to enable interoperability. Rear Admiral Gerd Glang, Office of Coast Survey, National Oceanic and Atmospheric Administration, USA. For NOAA’s Office of Coast Survey, building a product that provides decision-making tools necessary... (read more)

Kongsberg Adds Hydrographic Equipment to Portfolio

The EA440 singlebeam echosounder is developed for hydrographic use in shallow to medium-depth waters. It supports portable and hull-mounted sidescan and sub-bottom light for shallow waters. Kongsberg Maritime has also presented the portable acoustic positioning system ┬ÁPAP (MicroPAP) for tracking ROVs, tow fish, divers and other subsea objects. With the EA440, users can cover several applications with a single system. Instead of running separate systems with syn­chronisation issues the EA440 can cover different applications simultaneously. Individual transducer channels may also be reprogrammed to use different frequency band. Up to eight high-power transceivers can operate simultaneously from the EA440 echo sounder.... (read more)

Planet Ocean to Distribute Seastick

Planet Ocean has announced its partnership with Italian autonomous underwater vehicle manufacturer GABRI covering the UK and Ireland. The GABRI Seastick AUV incorporates several features that set it apart as an AUV and it can also be used with a tether turning it into a powerful remotely operated vehicle. The all-plastic construction gives it an extremely low magnetic signature. Together with the traditional forward dive controls and stern rudders the SEASTICK incorporates two, variable pitch thrusters using low power, silent, frictionless, magnetic induction motors which allow hovering and vertical movement in the water column. Fully customisable payload drawers and choice... (read more)
