Offshore wind: One-stop Power Conversion

With the United States and China about to start their respective offshore wind build-ups, grid operators wondering about the efficiency of their turbines or the emissions-areas compliance of their wind-service vessels will be warmed to know there’s someone they can talk to. Yaskawa’s The Switch — a Japanese industrial giant’s European environmental tech business — is offering one-stop wind-energy shopping. As with shipping, you can order permanent magnet generators, drives and converters for your wind turbines. Take heart. The lingo is the same. Yaskawa’s The

U.S. Military Trials Swarmdiver

UUV Aquabotix Ltd (ASX:UUV)  was awarded an approximate $150,000 contract for the purchase of its SwarmDiver system along with training and test support for the United States Military.This hardware and services sale will enable necessary government evaluation activities for the Military’s consideration of operational use of the product in theater.This award represents the fourth (4th) order placed by the United States Armed Forces related to the SwarmDiver family of vehicles since the product’s launch in April 2018.

Unheard Underwater: Covert Communications

subsea and remain covert. This is great news for a new generation of submariners and new unmanned underwater vehicle (UUV) concepts.Unmanned vehicles as a force multiplier for submarines are not a new idea. In 1997, the National Research Council published Volume 6 of the “Technology for the United States Navy and Marine Corps, 2000-2035”. In this document, the authors detail how AUV/UUV systems will be used in support of operations and cite secure communication links as a requirement to make this vision happen. BlueComm 200 UV can provide this link, securely and covertly.With BlueComm 200

AIS Data: History & Future

, for governments to get involved.  They started installing shore-based receivers to monitor AIS transmissions from approaching ships, out to a point just beyond the horizon.  Those governments could also monitor ships in harbors and transiting off the coast or on inland waterways.  The United States incorporated this data into its maritime security or maritime domain awareness programs.  Governments also utilize the data to analyze marine casualties and to determine waterway usage.  A large amount of AIS data is collected by governments around the world, which share much of that

Deconstruction work on the old bridge continues.Business Challenge: The retired Tappan Zee Bridge opened in 1955, and served more than

Export Licensing: Tips U.S. Exporters Shouldn’t Overlook

. A license may also be required because of the end use or end user. Items not licensed by BIS may still require a license from other agencies, including the State Department for defense articles and services subject to the International Traffic in Arms Regulations which are listed on the United States Munitions List (USML). When it comes to determining whether your export might need a license, there are a few sometimes overlooked aspects that U.S. businesses should be aware of before they export. After reading, go to our video web page to find out more about export licensing.• Don'

These companies utilize a varying degree of equipment from sonar systems to underwater metal detectors.Marine Diving Service, which provides marine diving services to customers on the east coast of the United States, utilizes JW Fishers’ Pulse 8X in its daily operations. Marine Diving Service's salvage track record includes everything from small objects to big vessels, and even a historic tug boat engine.In a recent search, Captain and diver Zdenek Ulman used the Pulse 8X to locate and retrieve

Ocean, Munk’s team transmitted low-frequency underwater acoustic signals. The location had been chosen because the sound waves could travel on direct paths to listening stations in both the Pacific and Atlantic oceans. The premise was validated as stations from Bermuda to New Zealand to the United States West Coast all received the signal. The time the signal took to travel was a function of the temperature of the water it traveled through.After being widowed by wife Judith in 2006, Munk found love again. In 2009, he met Mary Coakley, chair of the Friends of La Jolla Shores organization, and

Agency-Energy (ARPA-E) program, Aerodynamic Turbines, Lighter and Afloat, with Nautical Technologies and Integrated Servo-control (ATLANTIS). ATLANTIS projects will develop new technologies for floating, offshore wind turbines (FOWTs) using the discipline of control co-design (CCD).“The United States has 13,000 miles of shoreline, which is a huge opportunity to lead the world in capitalizing offshore wind,” said U.S. Secretary of Energy Rick Perry in a press release. “The ATLANTIS projects will help advance American offshore wind production and the accompanying job, manufacturing
