QYSEA and Water Linked, two of the undoubtedly most exciting underwater technology companies at the moment, have partnered up to equip QYSEA’s Remotely Operated Vehicles (ROV) with cutting edge underwater positioning sensors. The Water Linked A50 Doppler Velocity Log (DVL), the world’s smallest DVL, will be the standard fit for QYSEA’s FIFISH V6 EXPERT, PRO V6 PLUS and PRO W6 ROVs moving forward; an addition that is welcomed by a market demanding increased vehiclecapabilities.

Norwegian researchers are working on projects that are providing the groundwork for a revolution in aquaculture. As a small part of this revolution, Nortek’s DVL is helping to bring autonomous navigation to ROVs used in Norwegian fish farms.

Underwater technology provider Sonardyne International Ltd. has announced important new additions to its 2020 product line-up, all designed to play a role in delivering users’ data from the seabed to the shore.

Teledyne RD Instruments (TRDI) announces the launch of its new next-generation Doppler Velocity Log (DVL), the Tasman DVL. In 1995, Teledyne RDI designed and manufactured the industry’s first DVL, the Workhorse Navigator. The Navigator remains the gold standard, with thousands of units delivered globally to provide precision, onboard navigation for subsea and surface vehicles.

Innova AS, a specialist subsea engineering and technology company based in Norway, has selected acoustic and inertial navigation technology from Sonardyne International Ltd., for two new in-field resident ROVs (Remotely Operated Vehicles) being built in the country. 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 which is taking place this week in Geilo, Norway (8th-10th February). The two ROVs are being built by IKM Technology, this time for delivery to IKM Subsea, who has contracted Innova to supply various on-board sensors, including the navigation system, as part of the vehicle’s development programme.

The whole offshore industry was impatiently waiting for it: specifically designed for ROV navigation, ROVINS NANO provides highly accurate positioning at all depths, including for Middle Water Station Keeping. With now a full range of subsea inertial navigation systems, from ROV navigation to offshore survey, iXBlue can help you everywhere you need it under the sea.
