This Vast Animal Migration is a Critical Part of Earth’s Climate System

Every night, under the cover of darkness, countless small sea creatures – from squid to krill – swim from the ocean depths to near the surface to feed. This vast animal migration – the largest on the planet and a critical part of Earth’s climate system – has been observed globally for the first time thanks to unexpected use of a space-based laser. Researchers observed this vertical migration pattern using the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO) satellite – a joint venture between NASA and the French space agency, Centre National d'Etudes Spatiales – that launched in 2006....

How to Carry Out an Asset Inspection Survey

Bibby HydroMap, a UK-based company, has successfully completed an asset inspection survey of several bridges and the Weaver Sailing Club along the River Weaver in Cheshire (UK). This was an opportunity to demonstrate its marine 3D imaging capabilities in a highly dynamic and fast-flowing environment. The River Weaver is a marine connection between a number of businesses along the river and the Manchester Ship Canal and, ultimately, the Irish Sea, the integrity of which is paramount to their commercial operations. Locate Any Obstructions to Navigation The aim of the survey was to assess the condition of the bridges which span the... (read more)

Scanning Sonar for Poor Visibility Underwater Environments

US-based Blue Robotics is launching the Ping360 Scanning Sonar, which offers small ROVs the ability to navigate in low visibility water conditions. The Ping360 is a mechanical scanning sonar – it uses a small acoustic transducer mounted on a motor that rotates it in one-degree increments. As it rotates, it transmits and receives acoustic pulses to build a 360-degree image of the surroundings. This is similar to laser scanners and LIDARs used for ground robotics and autonomous cars, but using sound waves instead of light. Maximum Water Depth of 300 Metres When mounted on a remotely operated underwater vehicle (ROV),... (read more)

WASSP Technology Utilised by US University Students

Oceanography students at the University of Rhode Island have been busy utilising the latest in WASSP Multibeam technology as part of their research studies. The students, who are specialising in marine robotics, remote sensing and mapping have recently started using a WASSP S3 Multibeam system as part of a project to survey inland ponds and coastal estuaries. They have deployed the WASSP Multibeam system aboard a specially developed autonomous kayak.  WASSP, an acronym for Wide Angle Sonar Seafloor Profiler, is a multibeam sonar system manufactured by ENL Group in New Zealand under ISO9001/2000 certification. Research and development of WASSP commenced in... (read more)

iXblue and 2G Robotics Join Forces

iXblue and 2G Robotics have signed a Memorandum of Understanding (MoU) to offer a new survey skid for Inspection Class ROVs. This all-in-one integrated skid will deliver high accuracy inspection capabilities on small ROVs, enabling survey and inspection on low-cost assets. Using 2G Robotics’ ULS-500 Micro laser scanner and OBSERVER still camera, and iXblue’s Rovins Nano Inertial Navigation System, this new skid will offer a miniaturized laser scanner and navigation package dedicated to small-sized ROVs and AUVs. “The collaboration between 2G and iXblue reflects a shift in the industry to compact and low-cost solutions,” said Chris Gilson, 2G’s Product Development...

Basics of Hydrography and Inspection of Subsea Infrastructures

French positioning and geomatic specialist Geraud Naankeu Wati recently published his first book entitled 'Basics of Hydrography and Inspection of Subsea Infrastructures – Principles and Practice'. After several years of experience in hydrography and inspection of subsea infrastructures, the author noticed that it is important for professionals and orderers to have knowledge of these fields and decided to share his theoretical knowledge and experience of the field in positioning, hydrography, and inspection of subsea. “I wanted to contribute to the training of surveyors and meet the needs in hydrography and inspection of subsea infrastructures. I also intend to help the orderers to... (read more)

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)

Department of Fisheries and Oceans Canada Inspects the High Arctic

The Department of Fisheries and Oceans Canada in Manitoba will use a SEAMOR Marine Remotely Operated Vehicle (ROV) to inspect the High Arctic area which remains frozen year-round. The Chinook ROV will take part in research and evaluating ways to protect this special ecological region. The vehicle will also be used to conduct ecosystem identification and benthic surveys (underwater mapping of the seafloor) and inspection of first-year ice and multi-year ice. Auto-altitude system SEAMOR Marine's Chinook ROV will be equipped with a handheld pendant controller, and a fibre optic tether multiplexer upgrade. These will help control a wide array of...

Advances in High-speed Underwater Remote Vehicles for Subsea Pipeline Inspection

The Benefits and Challenges of the Technological Revolution in the Pipeline Survey Industry
The pipeline survey industry has undergone a technological revolution in the past couple of years, and the consequential benefits and challenges are only just beginning to be fully realized. The cost efficiency of subsea operations has been one of the key focus areas of the offshore energy industry in recent years. This focus, combined with increased growth in the amount of subsea infrastructure now in-situ on the seafloor, has seen a rising need for innovative approaches to subsea asset inspection. These solutions need to be cost-efficient, maintain data quality, and be able to provide a platform that supports future technologies.... (read more)
