Swells Neutralised During Offshore Maintenance

17.02.2005


In future, the maintenance of, for example, wind turbines at sea, will be made easier and safer by a Delft invention, the ‘Ampelmann’, which compensated for swells at sea. Tests with scale models have shown that by mounting the working platform of maintenance ships on an Ampelmann, the platform will remain still and work can take place more efficiently. On Friday 18 February at TU Delft, the invention will be demonstrated to representatives of the Ministry of Economic Affairs, the director of Shell Nederland, the chairman of the TU Delft Executive Board and other governmental, scientific and industrial representatives.



The Ampelmann uses the same technology applied in flight simulators, a mechanical system with six large hydraulic cylinders. By accurately measuring the movement of the ship, and controlling the cylinders accordingly, the platform can be held in a fixed position relative to the object being worked on. This also makes it possible to safely board the structure with a simple bridge. This makes such off-shore structures far more accessible for maintenance crews. Currently, it is impossible to work on off-shore wind turbines 20 percent of the time, due to swells at sea. Using the Ampelmann, this could be reduced to around seven percent. Improving maintenance can increase production and efficiency.

At the European Wind Energy Conference in 2004, PhD student Jan van der Tempel won first prize for this idea in a field of 300 international entrants. "In Europe, about fifty wind parks have been planned, each with 30 to 300 turbines. Moreover, world wide there are seven thousand offshore production units that could benefit from this technology. There is therefore a great interest in the concept." Van der Tempel will soon start his own company, which will develop a prototype of the system in 2006. The patent remains in the hands of TU Delft.

Im Focus: Basel Physicists Develop Efficient Method of Signal Transmission from Nanocomponents

Physicists have developed an innovative method that could enable the efficient use of nanocomponents in electronic circuits. To achieve this, they have developed a layout in which a nanocomponent is connected to two electrical conductors, which uncouple the electrical signal in a highly efficient manner. The scientists at the Department of Physics and the Swiss Nanoscience Institute at the University of Basel have published their results in the scientific journal “Nature Communications” together with their colleagues from ETH Zurich.

Electronic components are becoming smaller and smaller. Components measuring just a few nanometers – the size of around ten atoms – are already being produced...

  • Milestone on the road to operating emission-free ferries

The world's first electrical car and passenger ferry powered by batteries has entered service in Norway. The ferry only uses 150 kWh per route, which...

Im Focus: Into the ice – RV Polarstern opens the arctic season by setting course for Spitsbergen

On Tuesday, 19 May 2015 the research icebreaker Polarstern will leave its home port in Bremerhaven, setting a course for the Arctic. Led by Dr Ilka Peeken from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) a team of 53 researchers from 11 countries will investigate the effects of climate change in the Arctic, from the surface ice floes down to the seafloor.

RV Polarstern will enter the sea-ice zone north of Spitsbergen. Covering two shallow regions on their way to deeper waters, the scientists on board will focus...

Im Focus: Gel filled with nanosponges cleans up MRSA infections

Nanoengineers at the University of California, San Diego developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA (methicillin-resistant Staphylococcus aureus), an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA - without the use of antibiotics. The researchers recently published their findings online in Advanced Materials.

To make the nanosponge-hydrogel, the team mixed nanosponges, which are nanoparticles that absorb dangerous toxins produced by MRSA, E. coli and other...
