Ocean Noise: Pile Driving Triggers Alarm Responses in Squid

them the ability to create extraordinary camouflage, enabling them to blend into the background and avoid becoming a meal.Jones and his colleagues in the Sensory Ecology and Bioacoustics Lab at WHOI exposed longfin squid (Doryteuthis pealeii) to pile driving sounds originally recorded near the construction site of the Block Island Wind Farm in Rhode Island. The squid exhibited the same types of natural alarm and defense behaviors when they were exposed to the noises, but it’s what they did next that surprised the researcher team.“The alarm behaviors occurred within the first several noise

Trimble Marine Construction Software for Positioning

for pre-/post-dredge surveys to identify high and low spots, calculate progress volumes and send grid model updates to both the office and the dredge vessel. Supporting a wide range of sensors, it can also be used for simple navigation tasks like tug, workboat or barge positioning at the dredge/construction site. Trimble Marine Construction Software for Positioning supports subscription electronic charts, open-source charts and Automatic Identification Systems (AIS) for improved safety and navigation in congested waterways, use it to accurately and efficiently place Aid to Navigation (ATON) buoys and

4G mast, by pulling a fiber cable from their existing network of subsea fiber cables and then beaming communication service during field construction phase when communication isn’t otherwise available,” says Hjetland. The floating structure will also house solar panels. The specific construction site has yet to be decided – it could be oil and gas or renewables.“It could also be a platform for flying drones from for wind farm blade inspection,” he adds, “or at coastal fish farms. For oil and gas, standalone power and communications can offer charging power and control

Kvaerner to Study Floating Wind Structures

concrete substructures for offshore wind turbines can be designed and constructed for the planned Hywind Tampen project in the North Sea.The objectives of the front-end engineering and design (FEED) assignment are to further mature the design of the concrete substructures, to identify appropriate construction site(s), and to develop a plan for construction, method and cost for production of 11 floating concrete substructures, Kvaerner said.“Another important part of the FEED contract is to establish an improvement agenda that targets cost and schedule drivers with the purpose of establishing the

Explosives Cleared from Baltic Sea Wind Farm Site

Remaining munitions from World War I, World War II and the Cold War have been removed from the site of the future Arkona offshore wind farm in the German Baltic Sea, allowing installations to begin securely in 2017 as planned.   The construction site, with an area of 39 square kilometers halfway between the island of Rügen and the Danish island of Bornholm, is now completely free of explosive ordnance, E.ON announced.    The operation to clear the site of explosives took four months in all and started with an examination of the seabed. State-of-the-art cameras and sonars

astronaut. But that all changed when he was introduced to archaeology and history at age 10.   Just four years later, growing up near the Santa Teresa foothills in San Jose, California (now famed as “Silicon Valley”), the 14-year-old with a love of the past talked his way onto a construction site where bulldozers were unearthing the burials and artifacts of the Ohlone people who had lived thousands of years ago in the area.   The outline of golden-stained ribs and the curve of a skull protruded, fossil-like, from the sidewall of a trench, he remembers, tantalizingly called him

James Fisher Secures £25 Mln Wind Farm Project

farm some 27 kilometers off the coast of Suffolk, U.K.   The contract, worth in excess of £25 million, means that James Fisher will be responsible for providing key elements of marine services and support to the Galloper team during the construction phase of the wind farm including; construction site set-up, marine co-ordination, OWMS marine management system, crew transfer vessels, vessel refueling and emergency response services. The contract also includes provision of ad-hoc support arrangements for diving services, operation of remotely operated vehicles (ROVs), and unexploded ordnance

Brazil FPSO Shifts to Field Location

production targets forecast in the 2013-2017 Business and Management Plan. This vessel was converted into an FPSO (Floating Production, Storage and Offloading) from the tanker BW Nisa at the Cosco Shipyard in China, with the latter stages of construction carried out at the QUIP/Honorio Bicalho construction site in Rio Grande (RS). The services were carried out by the Quip consortium (Queiroz Galvão, UTC, Iesa and Camargo Correa) and BW Offshore and employed about 1,500 workers at peak construction.

. To enable early detection of a potential threat, it was important to perform geological mapping of the initial conditions of the river bottom, and proceed with regular monitoring missions to track the changes that might occur during the construction period. Hydrographic survey operations at the construction site were carried out with the EvoLogics Sonobot - a light unmanned surface vehicle for bathymetry and seafloor imaging in harbors and inland waters. Equipped with an accurate DGPS with RTK, it provided positioning data with centimeter accuracy. The Sonobot’s single-beam echo sounder, based
