In December 2016 at The Underwater Centre in Fort William, Scotland, DOF Subsea (DOF) conducted a demonstration of dynamic underwater laser scanning as a replacement for traditional metrology techniques using 2G Robotics’ and Sonardyne’s complete dynamic survey solution. The demo showcased the complete dynamic survey solution, which integrates 2G Robotics’ underwater laser scanner, the ULS-500 PRO, with Sonardyne’s inertial navigation sensor, SPRINT; Syrinx DVL and 6G acoustics. Seatronics, channel partner for 2G Robotics and provider of Sonardyne rental equipment, provided sensors and project/technician support. Historically, metrology campaigns using Long BaseLine (LBL) acoustics and photogrammetry have demanded significant vessel and ROV time. Additionally, LBL requires physical interaction with the subsea assets and photogrammetry is unable to provide real-time results. The goal of the demo was to quantify the reduction in operational time and increased accuracy of dynamic laser scanning for subsea metrology.

Like many organisations, subsea technology company Sonardyne Inc., uses trade shows to launch new products, speak to users about their requirements and identify industry trends. And whilst conversations first held at events regularly lead to a purchase decision, it can be weeks or months later before an order is actually placed. But that wasn’t the case during the recent Underwater Intervention show in New Orleans when equipment rental company Survey Equipment Services (SES) of Houston, placed an order during the show for a Sonardyne Mini-Ranger 2 USBL tracking system and multiple Nano transponders. SES’s clients regularly carry out inspection projects using divers working from small boats and barges. Sonardyne’s Mini-Ranger 2 USBL and Nano technology is perfectly suited to these short duration projects; it’s quick to install and easy to use, meaning that tracking underwater targets begin in just a few simple steps.

University of Hawaii researchers partner with Schmidt Ocean Institute to map 11,000 square kilometers of the ocean floor, creating detailed images of major seamounts. HONOLULU, HAWAII – In a recent research expedition sponsored by Schmidt Ocean Institute (SOI) and led by University of Hawaii scientist Dr. John R. Smith, over 11,000 square kilometers of the ocean floor were mapped in high-resolution for the first time. Smith, working with Jonathan Tree, University of Hawaii, and Joyce Miller, used multibeam sonar on SOI’s research vessel Falkor to generate detailed maps of portions of the remote Johnston Atoll Unit (JAU) of the Pacific Remote Islands Marine National Monument (PRIMNM).

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.

Teledyne Gavia, manufacturer of the Gavia Autonomous Underwater Vehicle (AUV), announced the release of a new Side Scan/Bathymetry module that incorporates Klein Marine Systems’ new UUV-3500 high-resolution side scan sonar with optional bathymetry sonar. The system is another high quality option for customers interested in utilizing the Gavia AUV for geophysical survey, cable and pipeline survey, environmental survey, and under ice survey, as well as Mine Countermeasures (MCM), Rapid Environmental Assessment (REA), and Intelligence, Surveillance, and Reconnaissance (ISR) surveys.

Sonardyne Inc., Houston, today announced it has supplied acoustically-aided inertial navigation technology to offshore engineering, procurement, construction and installation company, McDermott International, Inc., for its Lay Vessel 108 (LV 108). The Ranger 2 Pro DP-INS system, the highest specification available from Sonardyne, is being used to support touchdown monitoring surveys of submarine cables, umbilicals and pipelines and as an independent position reference for the LV 108’s Kongsberg dynamic positioning (DP) system.

A major metrology campaign conducted off the coast of Western Australia has been completed in just 26 hours thanks to the time saving features offered by specialist survey software supplied by subsea technology company Sonardyne International Ltd, UK. The project was led by global offshore construction company, EMAS CHIYODA Subsea (ECS), who was contracted by Apache Energy to install infrastructure at the Julimar natural gas field. The scope of work included installation of two manifolds, connected by five 30 metre vertical spools and five 80 metre horizontal spools

Brazil’s most advanced ROV support vessel (RSV), the Fugro Aquarius, has specified acoustic positioning technology supplied by Sonardyne Brasil Ltda., to support its subsea inspection, repair and maintenance activities in the region. Already delivered and fully commissioned, the Ranger 2 Ultra-Short BaseLine (USBL) system is being used to track the precise position of the vessel’s Work-class ROVs in water depths of upto 3,000 metres. It is also providing the vessel’s dynamic positioning (DP) system with position reference data to allow it to remain on-location whilst survey operations are underway.

Hydrographic survey and diving equipment specialists, Unique Group, has selected subsea vehicle positioning and navigation technology from Sonardyne International Ltd, to add to its expanding equipment rental pool.

Maritime security company, Sonardyne International Ltd., UK, has announced that it has supplied forward-looking sonar technology to MARSS Group of Monaco for a 120 metre-plus private vessel that was recently delivered to its new owner in Europe. The NOAS (Navigation and Obstacle Avoidance Sonar) system was specified for the unnamed vessel to allow it to explore remote, poorly charted places with the assurance that potentially hazardous underwater obstacles can be identified and avoided. The contract also included the supply of Sonardyne’s market-leading diver detection sonar, Sentinel. This complements the NOAS installation to enable the detection of underwater intruders approaching the vessel when stationary.

Equipment that simulates acoustic positioning operations on dynamically positioned (DP) rigs and ships, has been supplied by Sonardyne Brasil Ltda. to vessel control and automation company, GE Power Conversion for their new training school in Macaé.
