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

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

US Senators from 12 States Seek Offshore Drilling Exemptions like Florida's

Twenty-two Democratic U.S. senators from 12 states on Thursday joined the chorus of local representatives seeking exemptions from Interior Secretary Ryan Zinke's newly proposed offshore drilling plan, after his surprise move on Tuesday to shield Florida.   Zinke surprised lawmakers, governors, and industry groups on Tuesday night by announcing that Florida would be removed from the Interior Department's proposal to open up over 90 percent of federal waters to oil and gas leasing.   Zinke had met in Tallahasee with Republican Governor Rick Scott who told the Interior chief that drilling

Scientists Study Largest Underwater Volcanic Eruption

In July 2012, airline passengers flying over the Southwest Pacific Ocean spotted a large and unusual object floating on the water’s surface.    That object, which turned out to be a giant raft of pumice, was evidence that an underwater volcanic eruption had occurred. And as the raft continued to grow to roughly the size of Philadelphia, scientists observed that the eruption was extraordinarily large.   The eruption had occurred at the Havre volcano northeast of New Zealand, and was the largest to take place underwater in the past century.   “We knew it was a

A proposed leasing plan unveiled last week aims to open up all U.S. coasts to drillers over the next five years. Alaska and Maine are the only two U.S. states whose governors have expressed support for the plan.   The governors of

US Rivers Getting Saltier, Drinking Water at Risk -Study

U.S. rivers and streams have become saltier and more alkaline over the last 50 years, posing risks to drinking water by damaging pipelines and other infrastructure, according to a study released on Monday.   As municipal workers dump salt on roads to combat ice and farmers put fertilizer on fields, the runoff has made U.S. waterways saltier and more alkaline, according to the study, which examined decades of data recorded from 232 U.S. Geological Survey monitoring sites.   Salt can also be released by floods that reach sewage systems and spill the contamination into waterways, as well as

When the researchers took density of snow into account, they found that ice shelves lost about five times more ice by submarine melting than they gained from new surface snowpack.   “Many people look at this ice-shelf data and will fit a straight line to the data, but we're looking at all the wiggles that go into that linear fit, and trying to understand the processes causing them,” said Fricker, who was

Trump Aims to Open Nearly All US Offshore to Oil Drilling

The Trump administration on Thursday proposed opening nearly all U.S. offshore waters to oil and gas drilling, a move aimed at boosting domestic energy production that sparked protests from coastal states, environmentalists and the tourism industry.   The effort to open previously off-limits acreage in the Atlantic, Arctic and Pacific oceans comes less than eight years after BP Plc's Deepwater Horizon oil spill in the Gulf of Mexico - the largest in American history. The disaster caused billions of dollars in economic damage and led former President Barack Obama's to increase regulation of the

In step with our Annual Planner, MTR’s energy reporter in Oslo, William Stoichevski, puts on his red, white and blue game face to report on the largest untapped market for offshore wind power in the world.    Block Island — U.S.-based Deepwater Wind’s five-turbine, 30-MW wind park —  was the first. It showed what was possible, what might not have been optimal and how long it all takes. Since then, incentives for onshore-wind have been curbed, while a tax credit for

New C-DRONE for Undisturbed Wave Spectrum Measurements

this problem, MARIN evaluated airborne drones for the measurement of wave characteristics. Airborne drones have become widely available over the past few years, have increasing reliability and have lowered in price. However, for wave elevation measurements under strong, gusty wind conditions in a harsh marine environment their applicability and reliability is limited. Moreover, commercial deployment of flying drones requires expensive certification and training. This led us to develop the C-DRONE: an autonomous/remote operated vehicle which can be deployed and retrieved using a rope and hook to measure

In late 2017, four 250kW-rated T2 bi-directional turbines were deployed in the Minas Passage within the bay.

New Remotely Operated Hydrographic Survey Boat

Teledyne Oceanscience has introduced a new remotely operated hydrographic survey boat suited for inland waters such as streams, rivers and lakes.   The new trimaran style Z-Boat 1250 is “sturdy enough for tough terrain but light enough to be one person portable,” according to Teledyne. The vehicle has a lightweight hull manufactured from acrylonitrile butadiene styrene (ABS) plastic, and is IP67 rated, which makes it well suited to survey in most water conditions. The vehicle weighs in at less than 50 pounds, including all instrumentation. A collapsible sliding crossbar makes the

Six AUVs Dive Simultaneously at 5,000+ Meter Depths

A fleet of autonomous underwater vehicles (AUV) recently launched during a survey mission in the North Atlantic have completed the deepest known commercial dive performed by multiple AUVs simultaneously.   The mission, carried out by seafloor monitoring, mapping and exploration firm Ocean Infinity, saw six Kongsberg HUGIN AUVs descend to ocean depths greater than 5,200 meters, reportedly a world’s first for this type of vehicle.   The 6,000m rated vehicles were launched on October 18, each with an independent mission that surpassed water depths of 5,200 meters, collecting MBES data

New Program Sets Out to Limit Drones’ Impact of Wildlife

minimize or eliminate resource disturbance issues due to scientific or recreational drone operations.   “Inexpensive, off-the-shelf drones have the potential to revolutionize biological monitoring and inspire a whole new generation to research, explore and photograph our ocean coastlines and marine environment,” said Matt Pickett, Director of Oceans Unmanned, “but they also pose a challenge to wildlife, as previously inaccessible habitats are exposed to new disturbances. ECO-Drone will engage and educate the user community to ensure all wildlife and their habitats are respected

Earliest Known Marine Navigation Tool Found

State-of-the-art laser scanning technology has helped researchers to confirm that an artifact recovered from the wreck of a sunken 15th century ship in the Indian Ocean is the earliest known marine navigation tool.   When the Blue Water Recovery team found the object in 2014, they believed it was an astrolabe used by mariners to measure the altitude of the sun during voyages, but they were not certain as there were no visible navigational markings.   The team approached Professor Williams, who conducts high-tech scanning analyses in his laboratory at WMG University of Warwick in the U.K.
