Damen Starts on Dredging System

Damen began work on the construction of a dredging system for the first Marine Aggregate Dredger (MAD). This vessel, which is being built at Damen Shipyards Galati in Romania for Cemex UK Marine Ltd., is designed to extract sand and gravel from the sea bed at depths of up to -55 meters.According to the builder CEMEX asked Damen to develop a system with no inboard dredge pipework, something which has never been done on a vessel of this size before. The thinking behind this was to avoid the possibility of the abrasive dredged material creating wear holes in the inboard dredge pipework on board

From elephant trunks to octopus legs, nature abounds with tentacles that are adept at precise manipulation.At Kraken Robotics, we wanted to see what nature could teach us about better manipulation methods for launching and recovering marine vehicles and equipment. Inspired by the sophisticated feedback loops and dynamic response times found in creatures such as the elephant, octopus and jellyfish—and even the occasional carnivorous plant—we undertook an 18-month research and development program into biomimetic design.Getting into or out of the water is by far the highest-risk operation for

Operation of marine survey vessels in shallow-water coastal environments is a dangerous endeavor. A subsurface obstruction can tear a multi-beam sonar from its tow cable, resulting in loss of the expensive device and potential delay in the expedition. Lost equipment, however, is a minor inconvenience compared to the equally real possibility of the ship running aground in poorly charted waters, endangering the safety of its crew and incurring millions of dollars in damage.For this reason, survey vessel operators invest considerable time and money to minimize the risk involved in each voyage. They are

The company started as the first pioneer of digital acquisition and processing for geophysical survey, and this innovation and emphasis on research and development (R&D) has characterized the company ever since. Coda Octopus has continued to lead the geophysical

Seatools to Supply Monitoring System for The Ocean Cleanup

Subsea technology company Seatools said it has won a contract to develop and deliver a remote offshore monitoring system that will be used to gain real-time insight into the performance of the first-ever ocean cleanup system.   The contract was awarded by The Ocean Cleanup, a Dutch nonprofit developing advanced technologies to rid the world’s oceans from floating plastic. The group will deploy the system during trials starting later this year on the U.S. West Coast.   “Besides the fact that we thoroughly support this meaningful initiative, the project is compelling from a

Expanded Waterfront for Oi18

for Oceanology International visitors, this year’s dockside and on-water demo programme has been expanded and will now comprise daily demonstrations to offer an even more valuable experience for those attending, whilst allowing exhibitors to share their product’s effectiveness in a marine environment. Exhibitors taking part in demonstrations for the dockside area of Oi18 have been confirmed as Braveheart, Briggs Marine & Environmental Services, CMS-Geotech Ltd, Deep Trekker, iXblue, Nord Slovakia, Norbit, R2Sonic, RTsys, Seafloor Systems, Sonardyne, Sound Metrics Corporation

University of Vienna Acquires New Multibeam Equipment

A project to create 3D models of pile dwellings in Austrian lakes thousands of years ago has resulted in the acquisition by the University of Vienna of a multibeam solution supplied by MacArtney.   The Ludwig Boltzmann Institute for Archaeological Prospection and Virtual Archaeology is a research institute dedicated to the development of new techniques and methodological concepts for landscape archaeology. Its research program combines geophysics, aerial imaging, computer science and geomatics to develop efficient and universally applicable approaches for non-destructive detection, documentation

UKHO Creates High Density ENC of the Bristol Channel

;The Bridge’, this ‘high density’ ENC displays depth contours at one-meter intervals, allowing ECDIS to set safety contours at corresponding levels to support navigation through shallow water.   ECDIS will select safety contours based on a safety contour depth value set by the mariner. As most charts contain depth contours at intervals of 2, 5, 10, 20 and 30 meters, ECDIS will sometimes have to set a safety contour at a deeper interval than the value set by the mariner. As a result of this, ships navigating in shallower areas like ‘The Bridge’ have had to cross the

Tritech Unveils New Multibeam Imaging Sonar

The new 720im sonar from U.K. manufacturer Tritech International Limited is said to be the world’s smallest multibeam imaging sonar.   As the latest addition to Tritech’s Gemini range, the small sized and competitively priced sonar brings multibeam imaging technology to situations not previously possible.   At 500g and 63mm wide, the 720im is significantly smaller than comparable sonars, yet it delivers superior quality sonar imaging from an ultra-compact unit thanks to state-of-the-art microelectronics and proven sonar technology.   “The Gemini 720im has been in

GD Mission Systems: Full-throttle Charge toward Autonomy

Carlo Zaffanella is vice president and general manager of Maritime and Strategic Systems (M&SS) for General Dynamics Mission Systems. The M&SS business includes submarine and surface ship electronic systems integration as well as the design, build and support of a broad array of subsurface, surface, air, airport and strategic subsystems, meaning he is perfectly positioned to lead MTR’s ‘vehicles’ edition, as in 2018 our attention turns from a specific products and systems, to the holistic web of connectivity between subsea, surface, land-, air- and space-based assets.
