Reaching for the higher winds
The hub heights of onshore wind turbines are shooting up to elevations of 100 metres and more in order to reach more consistent and faster winds and so produce more energy than is available at lower heights. In order to harness this higher grade energy, wind turbine towers must evolve to reach new heights. Many towers, and especially those of 100 metres and more, are nowadays made from concrete. However, this market is being constrained when it comes to increasing tower height because of the limited availability of the powerful cranes needed to erect such tall towers.
Esteyco, from Spain, has now developed a system of constructing very tall towers that avoids the need for these large, ‘heavy-lift’ cranes. The key to the process is the use of high capacity lifting jacks instead of high capacity cranes. According to Esteyco, this system, because it can be easily deployed in a modular form, will have virtually no limitation on the height of the tower or the size of the turbine that can be installed. The reusable hydraulic jacks are easily transported from one tower to another. The company also states that the system can be used both onshore and offshore. On page 6 you can read the full article about the system.
From 15 to 18 September 2015 the HUSUM Wind event is happening again in the German capital of wind energy. For the last 25 years HUSUM Wind has been the leading biennial trade fair for the wind industry. HUSUM Wind is now increasingly focused on the core market of Germany and its neighbouring countries. The exhibition concept is tailored to the needs of all potential participants from SMEs based in North Germany to international turbine manufacturers. In cooperation with Messe Husum, Windtech International is for the second time going to produce the only official daily show publication.
The HUSUM Daily will be prepared and edited by a team from Windtech International in cooperation with staff from HUSUM Wind. Each day we will work on the issue to be published the following morning. If you have editorial material you want considered for publication please make sure that we have it before 1 pm each day.
HUSUM Daily at a glance:
· Four issues printed overnight, one for every day
· Handed out to all attendees
· Will present the latest developments and hottest news
· Outstanding editorial and advertising opportunities for exhibitors
The approximately 20,000 visitors and over 600 exhibitors can expect an exciting programme covering the current challenges facing the wind industry during this year’s event and I hope too see many of you there in person.
Enjoy reading, and see you in Husum,
