Ocean Autonomy: Norway to the Fore

Marine autonomous systems working independently and in connected systems are fast becoming a growth sector within the ocean industry space, including the oil and gas industry.The emergence of new marine autonomous systems appears to be a weekly occurrence. As costs have reduced in numerous areas, from sensors to satellites, some of these systems are also coming within the grasps of ordinary citizens, as well as ocean scientists, looking to unlock the secrets of the deep.Part of the drive for these systems, in the oil and gas industry at least, is to reduce use of manned surface vessels, which are

The World’s Largest Ocean Garbage Patch is Growing Rapidly

The world’s largest heap of ocean garbage is growing at an alarming rate.   The 600,000-square-mile collection of ocean plastic and trash floating halfway between California and Hawaii known as the Great Pacific Garbage Patch now contains four to 16 times more plastic than previously estimated, with pollution levels increasing exponentially, new analysis reveals.   It’s estimated some 1.8 trillion pieces of plastic weighing 80,000 metric tons are currently afloat in the area, and it is rapidly getting worse, according to a study published Thursday in the peer-reviewed journal

Around the World in 49 Days

, Coville reduced the previous record for solo global circumnavigation by eight days. That record had stood for 12 years. In fact, Coville had previously made three unsuccessful attempts to break it. For two weeks, Coville’s route headed south from France down the Atlantic and far into the Southern Ocean. There he picked up strong winds called the Roaring Forties. In less than three weeks, Coville sailed clockwise around Antarctica keeping the Indian Ocean and Pacific Ocean à gauche. After 32 days of sailing, Coville finally turned north into the Atlantic, headed to his homeland and the finish

Parallel Events Add Depth to Oceanology International

A series of complementary showcases are set to make 2018’s Oceanology International the most comprehensive forum in the event’s 49 year history.   The Oceanology International 2018 exhibition and conference, will runs from March 13 to 15 at ExCel, London, as organizer Reed Exhibitions looks to expand the event’s remit. The 24th edition of this biennial global forum will spotlight technological developments including robotics, advanced sensor technology and autonomous systems. The conference program, meanwhile, will include 11 free-to-attend technical tracks, all chaired by

Valeport MIDAS SVX2 Selected by Saab Kockums

Oceanographic, hydrographic and hydrometric instrumentation manufacturer Valeport said it has secured a contract to supply four customized MIDAS SVX2 probes to Saab Kockums.   The MIDAS SVX2 is an advanced probe, combining sound velocity with salinity and density technologies to provide a versatile instrument which delivers superior data profiles. The MIDAS SVX2 was selected for its commercial off the shelf (COTS) status which contributed to project cost and lead time efficiency, Valeport said.   Swedish manufacturer Saab Kockums develops naval technology to design, build and maintain

Hydrographic Survey Vessel Converted for Autonomous Ops

ASV Global said it has converted a 26ft hydrographic survey launch to enable it to operate autonomously using the ASView control system, while maintaining its ability to operate in a conventional manned mode. The launch, which is part of the Canadian Coast Guard’s (CCG) fleet dedicated to the survey operations of the Canadian Hydrographic Service (CHS), will be used as a test platform for unmanned survey work.   This delivery to the CHS marks ASV Global’s 10th unmanned conversion of a customer vessel using the ASView system.   ASView enables the launch to follow planned

K-MATE Autonomy Controller Put to the Test

Supported by KONGSBERG experts and technology, the GEBCO-NF Alumni Team, one of 19 semi-finalist teams competing in the $7 million Shell Ocean Discovery XPRIZE competition, has completed technology readiness tests of its unique unmanned surface vessel (USV) / autonomous underwater vessel (AUV) concept and associated combination of communications hardware and software to process and transmit data remotely. The test event was held on the fjord outside KONGSBERG’s factory in Horten, Norway on Thursday, November 23.   All Shell Ocean Discovery XPRIZE teams will hold testing site visits around

Researchers Set out to Study the Southern Ocean

A team from Newcastle University has arrived in Antarctica this week as part of a major new research project to measure the rate of uptake of heat and CO2 in the Southern Ocean.   Dr. Miguel Morales Maqueda, Alicia Mountford and Liam Rogerson from Newcastle University have joined the ORCHESTRA research project (Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports) to carry out sea surface measurements using a Wave Glider.   Fitted with a GBS antennae – a highly accurate GPS system – the glider will survey the ocean surface, measuring properties such as

Kraken Sets out to Advance Offshore Digitalization

Oil and gas companies are no stranger to big data, technology and digital innovation, but Canada based marine technology company Kraken Robotics Inc. believes the industry has yet to take full advantage of the opportunities that derive from using big data and robotic technology in a meaningful way. A single drilling rig can generate terabytes of data every day, yet only a small fraction of it is used for decision-making, it said.   Now, under a contract recently awarded to Kraken subsidiary, Kraken Robotic Systems Inc., the company will develop underwater sensors and robotics in order to

Unique Tech Helps Monitor Underwater Volcano

 Helping the Spanish Institute of Oceanography (IEO) and both Canarian Universities to closely monitor the underwater volcano Tagoro off the coast of El Hierro Island in the Canary archipelago, RTsys has designed a combined seismic and acoustic system especially for the project.   RTsys designed a system combining three geophones – two pointing horizontally and one vertically – to measure ground movement in the area. A hydrophone was added to record the noise caused by the ground or by bubbles in the water formed by vibrations.    Submerged in October 2016, the
