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.

In the last decades, sea level has been rising continuously – about 3.3 mm per year. For reef islands such as the Maldives or the Marshall Islands a sinister picture is being painted evoking the demise of the island states and their cultures. Are the effects of sea-level rise already noticeable on reef islands? Scientists from the ZMT have now answered this question for the Takuu Atoll, a group of Pacific islands, located northeast of Papua New Guinea.

The ‘Internet of Things’ is growing rapidly. Mobile phones, washing machines and the milk bottle in the fridge: the idea is that minicomputers connected to these will be able to process information, receive and send data. This requires electrical power. Transistors that are capable of switching information with a single electron use far less power than field effect transistors that are commonly used in computers. However, these innovative electronic switches do not yet work at room temperature. Scientists working on the new EU research project ‘Ions4Set’ intend to change this. The program will be launched on February 1. It is coordinated by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR).
