Hybrid AUV/ROV for Survey and Inspection

The Modus hybrid is one of the first autonomous underwater vehicles (AUVs) to feature the capabilities and characteristics of a remotely operated vehicle (ROV). Modus Seabed Intervention has completed system integration and trialling of one of the subsea industries first commercially available hybrid unmanned underwater vehicles, thus driving performance, quality and cost-effective delivery of survey and inspection projects in the offshore, defence and oceanographic sectors. Working in partnership with Saab Dynamics for over three years, global subsea service provider Modus has developed the Saab Sabretooth specification for greater endurance and speed and is also developing advanced sensor payload packages and...

Oceanology International to have Three Points of Focus

When Oi08 opens at the ExCeL centre in London’s Docklands on 11 March, the exhibition and its accompanying conference will focus on the three important issues that have begun to dominate thinking in ocean science and technology: climate change, meeting future energy demands, and ensuring environmental and civil security. These have become interconnected issues, with expertise now moving freely between each of these apparently specialised sectors.<P> With a 3-day conference accompan­ying this major exhibition, it is almost inevitable that public concerns about climate change will attract considerable interest. The role of the oceans in global warming is likely to take... (read more)

Acoustically Aided INS and Lidar

Fast 3D Subsea Mobile Mapping and Contactless Metrology
Aerial mobile mapping using Lidar and GNSS-aided inertial navigation has revolutionised the efficiency of land and shallow-water bathymetric surveying. Now, fast ultra‑high resolution subsea mobile mapping is approaching. Millimetre-resolution Lidar sensors have emerged in parallel with major advances in tightly integrated subsea inertial navigation. Wideband Doppler velocity navigation (DVL), Long BaseLine (LBL) observations, Simultaneous Localisation And Mapping (SLAM), automatic calibration and forwards-backwards post-processing, join with Acoustically Aided INS (AAINS) to provide robust dynamic sub‑millimetre relative accuracy and centimetric-level accuracy over wide areas. Successful deepwater ROV trials in the Monterey Canyon, California, USA, have demonstrated the extremely efficient dynamic future of... (read more)

Teledyne ADCP in Action

More than 200 ADCP (Acoustic Doppler Current Profiler) experts came together at the Teledyne ADCP in Action conference in San Diego. By bringing these experts together, Teledyne has established a venue where scientists, engineers, developers, etc. can share their thoughts on different ADCP solutions thereby encouraging the ADCP industry to meet each other, exchange thoughts and ideas, learn the ADCP implementations and above all the face behind the instrument.   The conference was divided into paper sessions by users and co-sponsors and afternoon workshop sessions on more in-depth explanations of the ADCP technology and how the different ADCP products can...

How a Hydrographic and Ocean Technology Provider Organizes Interactive Presentations

What kinds of webinars appeal to the ocean technology community in these extraordinary times? Hydrographic and ocean technology provider Nortek has learnt that interactive digital events with an emphasis on learning and practical examples have a massive appeal. The Norway-based company has recently launched a live webinar series with over 20 classes and interactive presentations. These are tailor-made for people working with ocean technology, such as oceanography, subsea navigation, marine navigation and ocean surveying. The educational webinar series covers everything from real-time data collection near the coast to using acoustic Doppler current profilers (ADCPs) to estimate suspended sediment properly and how to get accurate...

Subsea vehicles equipped with Sonardyne navigation technology

Oceaneering International Inc. has ordered hybrid navigation systems from underwater technology specialist Sonardyne Inc. for its subsea resident vehicles Freedom and E-ROV. The two resident vehicle systems are to be fitted with Sonardyne’s SPRINT-Nav an all-in-one navigational instrument. SPRINT-Nav combines a SPRINT INS sensor, Syrinx 600 kHz DVL (Doppler velocity log) and a high accuracy intelligent pressure sensor in a single unit, making it one of the smallest and highest performing combined inertial navigation instruments on the market. Maintenance Free-deployments Oceaneering’s E-ROV has already proven the ability for battery powered remotely operated vehicles (ROVs) working in the oil and gas industry... (read more)

Long-endurance UUV Mission Completed

Bluefin Robotics, (USA), in support of the Naval Research Laboratory (NRL, USA), has successfully completed a long-endurance UUV mission from Boston to New York totalling over 100 hours with NRL's Reliant Heavyweight UUV. The multi-day mission exercised UUV autonomy methods and demonstrated the capability of a high-capacity energy configuration. The test was designed to push the boundaries of traditional UUVs with the objective to uncover the challenges and requirements for significantly extending UUV endurance for new applications. The exercise is part of a series to support NRL's research in UUV-based technology for the US Navy. Reliant is an advanced version... (read more)

Dynamic Laser Scanning Set to Innovate Metrology Techniques

In December 2016, DOF Subsea (DOF) conducted a demonstration of dynamic underwater laser scanning as a replacement for traditional metrology techniques at The Underwater Centre in Fort William, Scotland. The demo showcased 2G Robotics’ and Sonardyne’s complete dynamic survey solution. The solution 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. LBL and Photogrammetry Historically, metrology campaigns using Long BaseLine (LBL) acoustics and photogrammetry have demanded significant vessel and ROV time. Additionally, LBL... (read more)

Hydrographic Society Benelux

Workshop on Technical Developments During ­Europort As a side-event to Europort 2013, the Hydrographic Society Benelux organised a workshop matching the theme of the event ‘Pioneers in Maritime Technology’. The event was opened by Oystein Aasbo of Kongsberg Maritime Norway, giving a fascinating insight into new operational features of AUVs and what the future might bring. He predicted that some tasks such as Inspection, Maintenance and Repair, and positioning seismic bottom nodes, now often carried out using ROVs, could be performed by AUVs. He also showed the new Kongsberg Munin AUV and its features. Martin de Kievit of Trimble, the... (read more)
