Updates from SIEMENS



Training facilities around the globe
SIEMENS – Siemens has a total of four global wind service training facilities in Denmark, Germany, the UK and the U.S. for the special training of offshore service technicians. All four locations have received certification from the Global Wind Organization (GWO) for their offshore safety training. These facilities are equipped with full-size turbine components, climbing towers, classrooms, and other apparatus needed to mimic real-live conditions. This gives each Siemens technician the hands-on training to be prepared for later deployment.

It takes a special kind of individual to perform offshore wind service. The job requires advanced technical and classroom training and expertise as well as comprehensive safety training. This requires superior physical endurance and stamina, since they must be prepared for conditions that can change at a moment’s notice. The sea can be as unpredictable as the skies, and everyone has to be prepared. You cannot afford to be afraid of heights or be prone to seasickness. more> http://tinyurl.com/ow7rv9u

SPACE WATCH (history) · Shuttle and Station · 360° Virtual Tour

View from Space Shuttle Atlantis
NASA – STS110-E-5918 (17 April 2002) — This is one a series of digital still images of the International Space Station (ISS) recorded by the STS-110 crew members on board the Space Shuttle Atlantis following the undocking of the two spacecraft some 247 statute miles above the North Atlantic. Atlantis pulled away from the complex at 1:31 p.m. (CDT). After more than a week of joint operations between the shuttle and station crews, astronaut Stephen N. Frick, pilot, backed Atlantis away to a distance of about 400 feet in front of the station, where he began a 1 1/4 lap flyaround of the ISS, newly equipped with the 27,000 pound S0 (S-zero) truss, visible in this series of images. S0 is the first segment of a truss structure which will ultimately expand the station to the length of a football field.

View from Space Shuttle Endeavour
STS111-373-001 (15 June 2002) — Backdropped by the blackness of space and a blue and white Earth, the International Space Station (ISS) is now separated from the Space Shuttle Endeavour following the undocking of the two spacecraft over western Kazakhstan. Endeavour pulled away from the complex at 9:32 a.m. (CDT) on June 15, 2002.

STS111-708-057 (15 June 2002) — Backdropped by the blackness of space, this close-up view of the International Space Station (ISS) was photographed by a crewmember on board the Space Shuttle Endeavour following the undocking of the two spacecraft over western Kazakhstan. Endeavour pulled away from the complex at 9:32 a.m. (CDT) on June 15, 2002. The S0 (S-zero) Truss with the newly added Mobile Base System (MBS) is visible center frame.

New fatigue model could lead to more durable, efficient ships


R&D – Heikki Remes at the Aalto University School of Engineering, Department of Applied Mechanics, has developed a model making it possible to determine how fatigue sets in with various welded steel materials. The model allows for the development of lighter structures, and as a consequence, more energy-efficient ships.

At present the fatigue measurements used by classification societies are based on the average quality of the weld. The same design guideline is used both with traditional and more advanced structures. With the models that have been developed, it is possible to consider the difference between traditional and advanced structural joints and the impact on fatigue resistance. more> http://tinyurl.com/b4a58ub

View from Space Shuttle Endeavour
NASA – STS108-E-5635 (15 December 2001) — As seen in an overall view from a digital still camera aimed through a window on Endeavour’s aft flight deck, the International Space Station (ISS), now staffed with its fourth three-person crew, is backdropped against dark space. The scene was photographed during a fly-around survey by the shuttle following undocking.

STS110-E-6006 (17 April 2002) — The International Space Station (ISS), newly equipped with the 27,000 pound S0 (S-zero) truss, was photographed with a digital still camera by one of the astronauts on board the Space Shuttle Atlantis. Seen just above center frame, S0 is the first segment of a truss structure which will ultimately expand the station to the length of a football field. Atlantis pulled away from the complex at 1:31 p.m. (CDT) as the two spacecraft flew some 247 statute miles above Earth. After more than a week of joint operations between the shuttle and station crews, astronaut Stephen N. Frick, pilot, backed Atlantis away to a distance of about 400 feet in front of the station, where he began a 1 1/4 lap flyaround of the ISS.

Road to Nowhere: Federal Transportation Infrastructure Policy


INFOGRAPHIC

By Edward Alden – Transportation infrastructure is one of the pillars of a modern competitive economy. It allows people to travel to and from work easily every day. It permits goods to move quickly from U.S. factories to international markets, or from coastal ports to American retail shops, boosting productivity. It lets us hop in the car, or on a train or plane to escape for the weekend or a longer holiday, improving our quality of life and making the United States a more attractive place to live.

Americans understood this once upon a time, building the most impressive network of roads and airports in the world, as well as a solid freight rail system. But for far too long we have been living on that inheritance. more> more> http://tinyurl.com/bs9pf5h
