Boundary layer stability
FINO1 measurement campaign (OBLEX-F1)
Christian Michelsen Research AS (CMR)
In order to close existing gaps between the requirements and the observation data, the Norwegian Center for Offshore Wind Energy (NORCOWE) is conducting a measurement campaign in the FINO1 area from May 2015 to June 2016. The campaign is being implemented by Christian Michelsen Research AS (CMR) and the University of Bergen in collaboration with Research at Alpha Ventus (RAVE), R & D Center FH Kiel GmbH as platform operator, Fraunhofer IWES and the Center for Wind Energy Research of the Universities of Oldenburg, Hannover and Bremen (ForWind) as a research partner.
Above all, the aim is to test different types of sensors and technical equipment and to gain more experience in offshore wind. For this purpose, measurement campaigns will be carried out in the areas of atmospheric measurements, air-water interaction, oceanographic turbulence, buoy operation and sediment movement.

One of the main tasks of the campaign is to obtain unique data sets to study boundary layer stability under undisturbed offshore conditions. Measurements of wind, temperature and humidity profiles in the atmospheric boundary layer up to a height of 1,000 meters are performed using remote sensing technology. During the campaign, as many weather variations and different wave patterns as possible should be covered.
NORCOWE plans to install two lidar scanning systems and a microwave radiometer on FINO1 to study the atmospheric stability around the Alpha Ventus wind farm and the interaction of the wind turbines with the atmosphere and each other. The LIDARs provide data on the wind speed in front of, inside and behind the wind farm up to several kilometers high, while the microwave radiometer creates temperature and humidity profiles up to a height of 1,000 meters. In addition to the meteorological measurements, oceanographic instruments are mounted on two bases - a submerged buoy and an autonomous SailBuoy - and deployed near FINO1 for a shorter period of time. This instrumentation monitors wave statistics, surface currents and turbulence in the upper oceanic mixed layer. The collection of these data is indispensable for the estimation of turbine tower loads and scouring. In addition, these data are crucial for the study of air-sea exchange processes that affect the structure of the wind profile and atmospheric stability.
