The Front CoverA large number of new offshore wind farm projects are planned, and their construction will raise many difficulties. Until now, only a handful of real offshore projects have been completed but experience gained during their construction has already indicated that offshore building activities will have their own specific challenges. On page 7 you will find an article from Ecofys about this topic. (Copyright Belwind/Ecofys) Publisher's NoteFeatures

The Front CoverOn the frontcover is shown the Northstar modular tower; this is a tower that, once installed, looks just like the conventional cousin from which it has evolved. The tower is a modular, field-assembled panel design. With this design, tower panels can be added to increase the tower diameter and height. On page 7 you will find the article about the concept.

The Front CoverA technical concept that is being studied by more and more companies is floating wind turbines. In a recent announcement, AREVA Multibrid and SWAY (Norway) said that they have gone into partnership in order to develop deep-water floating wind turbine solutions. The difference from other concepts is that the turbine will be adapted to enable downwind turbine operation on SWAY’s tower solution. (image courtesy Sway) Publisher's NoteFeatures

The Front CoverLeviathan Energy has demonstrated that it can improve the power output of large wind turbines by over 40%, and at times of slow wind by over 100%. Leviathan Energy claims to achieve this surprising result without even touching the turbine. It uses algorithms to design a large structure, called the Wind Energizer, which alters the air circulation before it reaches the turbine. On page 7 you will find the articles about the Wind Energizer. Publisher's NoteFeatures

The Front CoverIn April 2009, offshore work started on the Rødsand 2 wind farm, in the south of Denmark. A concrete gravity-based foundation is to be used. A new method for the preparation of gravel beds has been developed. The seabed has been prepared by removing the soft top sediment and the square screeding frame is then placed in the pit (Figure 4). Gravel stone is placed inside the frame, and the hydraulic levelling of the gravel bed and all other operations are then carried out through remote control by staff in a follower vessel.

The Front CoverThe designers of tall buildings are showing an increasing interest in reducing the environmental impact of the construction and operation of their buildings. One such example is the Discovery Tower, which is currently under construction in Houston, Texas. The photograph on the cover shows the 1:300 scale model installed in an atmospheric boundary layer wind. Publisher's NoteFeatures

The Front CoverOver the last five years we have published several articles about lidar and sodar for wind measurements. Five years ago just a few people anticipated that lidar remote sensing systems would become so useful to the wind-power industry in such a short time. In this issue on page 7 we publish an article about the WindCube developed by Leosphere from France. Publisher's NoteFeatures

The Front CoverWind energy is providing the world’s fastest growing power source for electricity generation. It is clean, indefinitely renewable and abundant; however, it is also intermittent, and it is this intermittent nature that brings with it the biggest challenges for successfully integrating wind energy into the power grid. On page 7 you will find an article about capacitive and inductive compensation for reliable integration to resolve this problem Publisher's NoteFeatures
