    It was 40 years ago, in the time of the international oil crisis, that some of the first initiatives were undertaken by, what the Dutch now would call, ‘goat-hair wool sock men’ taking a look at wind as a source for generating energy. Reason enough for one of these ‘pioneers’, Chris Westra, to organise a day where the […]

    In the previous article we spoke about the importance of accurate wind measurement for an optimum wind farm design. But also underwater there are elements that need to be taken into consideration when designing the foundation and cable structures for each wind turbine. Waves and currents can cause erosion of the seabed around a fixed […]

    The OWI-Lab team attended the EWEA 2013 event in Vienna this month, the largest wind energy conference in Europe. More than 8000 participants and nearly 400 companies attended the conference and exhibition this year. Although 11.000 MW of wind energy capacity was installed last year, the wind industry is in fact facing tough times just […]

    Offshore wind energy continues to experience an increasing share of the electricity generation market in Europe. Both the UK and Germany have set up ambitious goals to further expand their offshore wind energy capacity. Relatively smaller countries such as Belgium for example are also stepping up their offshore capacity and are investing in research projects […]

    An important tool for reducing risks and costs in offshore wind is integrated, intelligent monitoring of the foundation structures. If well implemented an integrated monitoring approach will continuously track the ‘state of health’ of a foundation and identify in a very early stage the onset of structural problems. This allows early, low cost repairs, optimal […]

    There are some blunt facts about wind farm support vessels and some of them do not make pleasant reading. In the past four years there have been many wind farm support vessels built, some for existing companies and some for new companies. At the time they were ordered the prospects looked good with the UK […]

    The interest in structural health monitoring (SHM) in industry has increased significantly in recent years. Failure of a mechanical structure can indeed occur suddenly and provide a lot of damage. With SHM it is possible to follow up (online or offline) defects with permanently attached sensors. Damage to mechanical structures may consist of (small) changes […]
