Automated Target Recognition Options for Gavia Vehicles

Teledyne Gavia, a global leader in the manufacture of autonomous underwater vehicles (AUVs), has introduced Charles River Analytics’ AutoTRap Onboard AI-based object detection software as a new capability onboard their Gavia marine vehicles. As underwater operations become more complex and dangerous, AI technology has emerged as the clear solution for delivering the consistent and accurate results that have proven elusive until now, due to the challenges of ever-changing marine environments. The new partnership with Teledyne Gavia expands the boundaries for underwater unmanned sonar operation. Now, operators can acquire Teledyne Gavia’s best-in-class unmanned underwater vehicles with AutoTRap Onboard software inside. “AutoTRap... (read more)

Valeport Launches New Sensors for Subsea Survey and ROV/AUV Operations

Valeport, a leading manufacturer of oceanographic and hydrographic instrumentation, has further expanded its portfolio’s capability with the launch of two new sensors for ROVs/AUVs and subsea surveys. Valeport has launched the new miniIPS2 and new uvSVX, which both offer operationally specific interchangeable pressure transducers that deliver enhanced accuracy for specific depth ranges. These field-swappable sensor heads make it easy for users to select the correct pressure range for their work and offer increased accuracy at any depth, alongside streamlining benefits to users who previously required different instruments for shallow and deep water.  Interchangeable Pressure Module The smart miniIPS2 underwater pressure...

The IBCAO 4.0 Bathymetric Chart: New Depth Map of the Arctic Ocean

Scientists from the University of New Hampshire (UNH) and around the globe have published the most detailed map to date of the Arctic Ocean seafloor, which they hope will provide a glimpse of the geologic features that could affect global climate, the melting behaviours of the Arctic ice sheets, and ultimately sea-level rise. Using all available depth data, including new state-of-the-art multibeam sonar technology, and sometimes surveying areas never before explored by ship, the new compilation now has approximately 19.8% of the Arctic Ocean seafloor mapped, representing a 13% increase from the previous chart compiled in 2012. This improvement is the result... (read more)

iSURVEY Helps Identify North Sea Shipwreck

During a recent offshore power cable cut and seal project on the Olympic Taurus, iSURVEY were part of the team tasked with identifying a shipwreck found three years previously during a routine inspection of the Skagerrak power cable. The wreck lies 13 nautical miles from Kristiansand in southern Norway, and was investigated using an ROV-mounted multibeam echosounder. Following the survey, it was determined that the wreck was that of the long-lost German warship Karlsruhe, famous for leading the assault on Kristiansand during the invasion of Norway in 1940. Until this discovery, Karlsruhe had remained the last World War Two German warship whose... (read more)

Veripos Launches SPAN GNSS+INS for Hydrographic Survey Applications

Veripos has introduced SPAN GNSS+INS technology from NovAtel, also part of Hexagon, into the offshore oil and gas marine market. NovAtel and its SPAN technology have accelerated developments in GNSS positioning, sensor fusion and inertial navigation systems for over 15 years. Now, Veripos brings this proven technology to the marine market to optimize your positioning solution with GNSS and inertial measurement units (IMUs) to provide heading, attitude and heave measurements on the open water.  Through deep coupling, SPAN technology fuses measurements from the GNSS receiver and the IMU together to calculate robust and reliable position, heading, velocity attitude and heave....

Teledyne CARIS AI Software Contributes to Successful UTAS USV Mission

Teledyne CARIS, a Teledyne Technologies company, was an integral part of the illustrious team involved in the ground-breaking uncrewed offshore survey mission in the Atlantic Ocean. Teledyne CARIS’ Mira AI and CARIS Onboard software were present on the vessel to enable autonomous survey and real-time processing operations. The mission’s Uncrewed Surface Vehicle (USV) built by SEA-KIT mapped over 1,000 sq. kms of the ocean floor in 22 days, while being continuously monitored via satellite communications at its Remote Operations Centre in Essex, United Kingdom. A specialized team comprised of the GEBCO-Nippon Foundation Alumni Team operated the survey equipment and provided... (read more)

Applied Acoustics Launches Pyxis Integrated Inertial USBL System

Applied Acoustic Engineering (AAE) has announced the launch of its next-generation USBL system, Pyxis USBL. Taking its name from the constellation Pyxis Nautica – the mariner’s compass – Pyxis USBL combines the best of AAE’s subsea acoustic tracking technology with a highly advanced inertial navigation system (INS) from a respected name in the industry, to create a state-of-the-art, inertially aided Ultra Short Baseline system capable of accurate subsea tracking with survey-grade performance. The combination of AAE’s Sigma 2 acoustic protocols and SBG Systems' high-precision Navsight Apogee Marine INS brings together two leading names in the field of marine technology, resulting...

Fugro’s Bathymetric Lidar Improves Hydrographic Data Collection in Australia and Pacific Region

Fugro has successfully trialled a major upgrade to its Fugro LADS airborne lidar bathymetry (ALB) system. The enhanced LADS HD+ technology was developed in Fugro’s laser laboratory in Adelaide, Australia, and is a sophisticated hydrographic mapping system that accurately measures water depth in both the marine and coastal zone environments. The new advances to the system have doubled the laser speed and the swath width and improved the object detection of the system, greatly increasing data collection efficiency for nautical charting. The system builds on the proven Australian-developed LADS technology and has been designed for safe, high-speed and cost-effective surveys... (read more)

Saab Seaeye Panther Selected for Pipeline Inspection in Gulf of Mexico

For pipeline inspection in the Gulf of Mexico, global maritime, survey and ROV services operator ACSM chose an electric Saab Seaeye Panther XT robotic vehicle over other ROV vehicle alternatives. The Panther inspected 261 pipelines totalling 2,340km in four fields in the Gulf of Mexico (GOM), at depths ranging from 15 to 130 metres, in a less than 10-month project duration. ACSM chose the electric Saab Seaeye Panther because it can perform the full scope of work needed, yet is far smaller than hydraulic equivalents. Considerable savings come from deploying the 700kg Panther system rather than the much heavier hydraulic... (read more)

Sentinel-2 Coastal Charting Worldwide

The Hydrographers’ Final Search for an Effective SDB System
It is widely and wrongly assumed that the world’s coastal regions have been surveyed in detail by modern techniques and that the resulting nautical charts are an accurate reflection of the nature of the seabed. This optimistic approach is not shared by the world’s hydrographic offices or the International Hydrographic Organization (IHO). Hydrographers have a saying: “the world is fully charted, it’s a shame that so little is surveyed”, and one could add, looking at venerable charts, so poorly surveyed. Hydrographic offices and the IHO have been looking for years to find an affordable method to fill the coastal gaps in... (read more)
