Sonardyne SPRINT-Nav for Resident ROVs

Innova AS has selected acoustic and inertial navigation technology from Sonardyne International Ltd., for two new in-field resident ROVs (Remotely Operated Vehicles) being built. Each ROV will be installed with a co-housed Sonardyne SPRINT Inertial Navigation System (INS) and Syrinx Doppler Velocity Log (DVLs) to provide tightly coupled navigation data that will support a wide variety of survey and inspection missions in water depths up to 4,000 metres. The contract was announced on the opening day of the Seabed Mapping and Inspection conference taking place in Geilo, Norway from 8-10 February 2017. The two ROVs are being built by IKM... (read more)

ROV Mid-water Station Keeping

An affordable and functional solution for Mid-water Station Keeping (MWSK) has been on the wish list of most ROV operators and manufacturers for some time now; the huge benefits in terms of operational efficiency and the future potential for pre-planned automated missions has made it a case of when, not if.      Against this backdrop and at the request of C-Innovation,CDL and Schilling Robotics engineers started work on a collaborative solutionover twelve months ago, the results of that effort were demonstrated in Marchin the Gulf of Mexico following an extensive period of Factory Acceptance Tests.   Traditional ROV station...

Ultra-compact Teledyne RDI Pathfinder Doppler Velocity Log

Teledyne RD Instruments (TRDI) has launched its ultra-compact 600kHz Pathfinder doppler velocity log (DVL). The Pathfinder provides high-precision onboard navigation for subsea and surface vehicles in a small footprint for the latest generation of small autonomous underwater vehicles (AUVs), remotely operated vehicles (ROVs) and unmanned surface vehicles (USVs). Recently unveiled at the Ocean Business event in Southampton and OTC in Houston, the Pathfinder has immediately drawn intense interest and orders from vehicle manufacturers and users from around the globe. Derived from TRDI’s long-standing, highly reliable DVL technology, the Pathfinder delivers proven technology at a price point, size, and weight that’s... (read more)

Hybrid Underwater Vehicle Combines AUV and ROV Capabilities

The 'Fusion' hybrid underwater vehicle is a real breakthrough. It uniquely combines autonomous underwater vehicle (AUV) and remotely operated vehicle (ROV) capabilities with diver navigation and propulsion into one system, thanks to Nortek’s DVLs. Both the electronics and transducers are smaller and have a better form factor for the Fusion underwater vehicle. The higher frequency for increased accuracy is of huge value for aiding the Fusion’s automated control and navigation system. The added dedicated altimeter provides more accurate altitude directly below the Fusion for better terrain following. Nortek’s 1MHz DVL has a bottom track that ranges from 20cm to 50m... (read more)

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)

ROV DP Capabilities Demonstrated

A recent trials partnership between Sonardyne International, UK, and USA-headquartered Oceaneering International has resulted in the development of a Fly-By-Wire (FBW) system for ROV control in any water depth, allowing the vehicle to hold station indefinitely and navigate to real-world coordinates automatically. A Sonardyne SPRINT system was installed on one of Oceaneering’s Maxximum ROVs and integrated with a Sonardyne Ranger 2 Ultra Short Baseline (USBL) system for acoustic aiding of the Inertial Navigation System (INS). The trials took place in the Gulf of Mexico in water depths of 3,057 metres (10,030 ft) and results showed that continuous hovering of the... (read more)

Collaborating to Make ROVs Small and User-friendly

Putting together a highly specified remotely operated underwater vehicle (ROV) is a complex business, requiring fluid integration of components and software from several different manufacturers. Getting it all to work together takes a high level of collaboration between professionals, located around the world. When VideoRay was designing a subsea vehicle so compact it could be checked in as luggage at the airport, it teamed up with Nortek to keep the size down, while keeping the positioning accuracy high. A case in point is the deployment of Nortek’s DVL1000 Doppler Velocity Log on the Defender models now being produced by Pennsylvania-based... (read more)

SeaPILOT Expanded for Observation-class ROVs

Rowe Technologies, USA, has launched a DVL for the SeaPILOT product line. The SeaPILOT OC (Observation Class) is the result of collaboration with several small ROV manufacturers to provide a compact, high-performance DVL, designed specifically for observation/inspection-class ROVs. The OC is small (5” [127mm] wide x 6” [152mm] tall and 8” [203mm]), light-weight (~1lb [0.45kg] in water), is rated for 300m operating depths, and is available in 1200kHz and 600KHz operating frequencies. To ease integration, the OC supports several input and output data formats and is compatible with a number of third-party control and navigation software packages. (read more)
