New Navigation Module for Gavia AUV

Teledyne Gavia, manufacturer of the Gavia autonomous underwater vehicle (AUV), said it has released a new navigation module that incorporates iXblue’s new Phins Compact C3 with a Teledyne RDI 1200 kHz Workhorse. The system is another high quality option for customers interested in high accuracy navigation at a competitive market price and in a compact form, Teledyne Gavia said. The Gavia AUV can be utilized in various applications, including geophysical surveys, cable and pipeline surveys, environmental surveys and under ice surveys, as well as Mine Countermeasures (MCM), Rapid Environmental

OSIL Rolls Out ROV/AUV Mounted Sediment Corer

U.K.-based Ocean Scientific International Ltd (OSIL) has introduced a new sediment corer designed to be mounted to the skids of remotely operated vehicles (ROV) or autonomous underwater vehicles (AUV).    The self-contained system will allow sediment samples to be collected during routine ROV operations and can be daisy chained together to allow multiple core assemblies to be installed as one system.  The assemblies are powered and controlled by the customers own skid control unit and have been pressure tested for use in depths of up to 1,200m, with deeper units currently in development

Coda Octopus Rolls Out New Real-time 3D Sonar

less power than that of the Echoscope 3G product line – all without compromising real-time 3D image and mapping fidelity, performance or capability, according to Coda Octopus.   Whereas the third generation was more compatible with the likes of work-class remotely operated underwater vehicles (ROV) and other vessels, Coda said its reengineered and repackaged 4G range expands the industry-leading technology to a broader number of market applications.    “Our real-time 3D sonar technology, which we brought to the market in 2005, is at the heart of Coda’s growth

Real-time Sonar Fit onto US Navy Minehunting AUV

A real-time synthetic aperture sonar (SAS) system has been integrated and tested on board a U.S. Navy autonomous underwater vehicle (AUV) that will perform minehunting duties for the Naval Undersea Warfare Center in Rhode Island.   The AUV, a fully modular REMUS 600 manufactured by Kongsberg Maritime subsidiary Hydroid, was designed through funding from the Office of Naval Research to support Naval operations requiring extended endurance, increased payload capacity and greater operating depth, such as minehunting.   The AquaPix MINSAS SAS, developed by Kraken Robotic Systems Inc.,

fully prepared to investigate a typical deep-sea explosive eruption,” said Adam Soule, WHOI associate scientist and chief scientist for the National Deep Submergence Facility.   “When we looked at the detailed maps from the AUV, we saw all these bumps on the seafloor and I thought the vehicle’s sonar was acting up,” Soule said. “It turned out that each bump was a giant block of pumice, some of them the size of a van. I had never seen anything like it on the seafloor.”   Havre is part of the Kermadec Arc, a chain of volcanoes, some of which reach the surface

ASV’s C-Worker 7 Goes to Work for Subsea 7

A 7-meter autonomous surface vessel (ASV) was recently deployed to support offshore services provider Subsea 7 during pipelay operations off the coast of Egypt.   The C-Worker 7 vehicle manufactured by U.K. firm ASV Global was fitted with a survey suite comprising a multibeam echosounder and side scan sonar in order to carry out touchdown monitoring in support of the pipelay vessel Seven Antares.   A custom payload frame was designed to house the survey suite specified for the mission. The modular frame slotted into the C-Worker 7’s moonpool to mount and deploy the sensors. Extensive

Expedition to Capture First 4K Images of the Titanic

A manned submersible set to survey the RMS Titanic wreck site this summer will be equipped with a range of high-tech underwater imaging equipment that will capture the first ever 4K images of the historic shipwreck. Starting in June 2018, manned submersible services provider OceanGate Inc. will lead a group of scientists, content experts and mission specialists to explore and survey the wreck site in a series of week-long missions from St. John’s, Newfoundland. For the mission, OceanGate's manned submersible Cyclops 2 will be equipped with cameras and lights from Canadian firm SubC Imaging

TechSurge: Advancing Oil Spill Research

The Marine Technology Society (MTS) and the Gulf of Mexico Research Initiative (GoMRI) are collaborating on an upcoming TechSurge event in New Orleans on February 5, 2018 that will focus on the effects of oil spills on the environment and public health. Recent investigations have yielded research results and technological advancements that will improve future studies and impact modeling efforts. The goal of this meeting is to bring together the GoMRI and MTS communities, share research findings, and begin discussions of how the two communities might work together to better prepare for the next oil

Researchers to Laser Scan Titanic Wreckage

A research team armed with the latest in state-of-the-art underwater technology will set out this summer to capture laser data of the RMS Titanic wreckage. The six-week expedition will depart from St. John’s, Newfoundland in June, sending scientists, content experts and mission specialists to explore the historic wreck site aboard OceanGate's manned submersible Cyclops 2, the first to survey the Titanic since 2005. In order to document the present condition of the shipwreck and debris field without physical interaction, the submersible will be equipped with 2G Robotics’ dynamic

Chinese Sub near Disputed Islands Stokes Tension with Japan

Japan’s defense minister criticized China on Monday for sailing an advanced stealthy nuclear submarine close to disputed islands claimed by Japan and China, saying the action had stoked tension.   The submarine, which Japan detected in the East China Sea, was a 110 meter-long Shang-class vessel, which is able to dive deeper and for longer than older boats and is armed with torpedoes and anti-ship missiles, according to Japan’s Ministry of Defence.   “Operating a submerged submarine close to another country’s territory goes against the norms of international rules

This also had to be verified by testing during the development of the clamp as this was a first-of-kind application.   Given the prolonged deployment of the clamp, an additional system was developed to allow the titanium rods to be re-tensioned subsea by a ROV (remotely operated vehicle) if it was observed that the grip on the cable was declining over time.   Performance Testing To test the performance of the clamp ahead of delivery to Subsea 7 (the subsea installation contractor), a specially designed test rig at RED Engineering’s test facility in the North east
