Subsea Mining: The Next Big Thing for UUVs

underwater vehicles (AUVs), remotely operated vehicles (ROVs) and new “drones” called HROV, DART or TURTLE. Among the indicators is the involvement of mining companies, governments, rich subsea players and the Dutch dredging community. New vehicles are being developed from Hungary to Hawaii, although Portugal, it seems, is at the forefront of new-vessel commercialization.Apart from dredging up gold and diamonds nearshore, underwater mining is about two activities: tapping the leftover mineral deposits in about 3,000 flooded and abandoned European mines and, more pertinently, mining

In the networks of this heavyweight science network, the limitations of AUVs are acutely known, and researchers from Hawaii to Hong Kong will attest, that it is harder to communicate with AUVs than it is with space probes and their “infrastructure of Deep Space Network for spacecraft.” While “power is an important shortcoming”, too, it’s the communications problem that keeps this triad of

points in Tonga: Neiafu, Nukualofa and Pangai. SubCom maintains these two cables in addition to 31 other systems as part of the SPMMA, which was signed in 2017. The agreement covers the South Pacific region from Singapore in the west to Tahiti in the east and from the southernmost point of New Zealand to Hawaii.SubCom Reliance is part of the company’s world-class fleet, purpose-built for cable deployment and maintenance. The ship was on standby in the South Pacific at a port in Apia, Samoa. SubCom’s highly trained crew of experienced merchant mariners, submersible engineers, and cable operations

Downed Fighter Jet Recovered off Hawaii

A remotely operated underwater vehicle (ROV) was recently used to help locate a downed fighter jet off Hawaii.The privately owned Hawker Hunter aircraft crashed on December 12, 2018 while participating in the Hawaii Air National Guard sponsored training exercise Sentry Aloha. The pilot ejected before the crash and was rescued by the Coast Guard with the assistance of nearby good Samaritans, but the plane was sent crashing into the ocean.The aicraft hit the water about 1 mile south of Honolulu in an area with many small boats. The number of boats in the area meant there were many cellphone videos

Vryhof Reports New Contracts

.The company will supply geotechnical expertise and drag embedment anchors to mooring specialists SOFEC for use in an oil and gas project, offshore Malaysia.Another Vryhof company, Moorlink, a provider of connectors and mobile and permanent mooring solutions, has secured a renewables contract in Hawaii, where its swivels will be put to use in extreme conditions. The new deal highlights Moorlink’s commitment to the emerging renewables marine energy market and its ability to customize innovative and cost efficient solutions for pressurized budgets made possible through more than 20 years expertise

Ocean Cleanup Device Malfunctions

A first-of-its-kind floating ocean cleanup system deployed to collect plastic pollution from the Great Pacific Garbage Patch has been taken out of service early after it broke apart while operating halfway between Hawaii and California.The wind- and wave-propelled cleanup system, launched from San Francisco in September by Dutch nonprofit The Ocean Cleanup, consists of a 600-meter-long U-shaped floating barrier with a three-meter skirt below that glides at the ocean surface to collect plastic and funnel all debris at its center.Operations have been put on hold after an 18-meter section separated from

They devised the LADCP method and processing (https://goo.gl/1TGXBn). Key input came from staff at the University of Hawaii and Lamont Doherty Geological Observatory in USA and IFM Kiel in Germany.Lowered ADCP MethodDeep current profiling measures below the acoustic range of ship-mounted profilers.

The OE Buoy is Taking Shape

constructing a marine hydrokinetic convertor called the OE Buoy for U.S. and Irish based wave-power pioneer Ocean Energy. Once completed in spring 2019, the 125 feet long, 68 feet tall, and 59 feet wide wave device will be towed to the U.S. Navy Wave Energy Test Site on the windward coast of O’ahu, Hawaii.The private sector project is supported by the U.S. and Irish governments and their agencies as part of an agreement committing both governments to collaborating on marine hydrokinetic technologies.The 125-foot OE Buoy has a potential rated capacity of up to 1.25 MW in electrical power production

The Ocean Cleanup Kicks Off

A first-of-its-kind floating ocean cleanup system is undergoing a final round of testing before it begins removing plastic pollution from the Great Pacific Garbage Patch halfway between Hawaii and California.The system developed by the Dutch nonprofit The Ocean Cleanup was launched from San Francisco Bay on September 8 and towed 350 nautical miles by the vessel Maersk Launcher to an offshore test site. System 001 will now undergo two weeks of trials before continuing its journey to start collecting debris at the world’s largest accumulation of ocean plastic some 1,200 nautical miles off the

Drone Boats to Face-Off in Global RobotX Challenge

Challenge will battle for cash prizes and bragging rights by completing a series of tasks to demonstrate navigation and control; obstacle detection and avoidance; station keeping and docking; and observation, identification and reporting of a specified target.The competition, set to take place in Oahu, Hawaii from December 8-15, will include students from 13 universities representing Australia, China, Japan, Singapore, Taiwan and the U.S.The purpose of the challenge is to foster innovation as students develop their skills in systems engineering and autonomous command and control, while collaborating with

Remote Monitoring System Delivered for The Ocean Cleanup

The primary goal of the Pacific trials is to confirm the performance of the cleanup system in a fully operational configuration, before commencing The Ocean Cleanup’s large-scale cleaning plans in the Great Pacific Garbage Patch.During the upcoming trials, Seatools&rsquo
