Measuring 3D with fields at the speed of light!

摘要

To analyse the dynamic behaviour of ships, platforms and wind turbines, accurate monitoring of the environmental conditions is essential. The deployment of offshore wind turbines with hub heights of up to 130 m, the development of wind assisted propulsion and the operation of high windage vessels such as container vessels and cruise ships in confined waters, regmre detailed information about the wind field over large areas and heights climbing to 300 m. In particular, the vertical profile of the wind speed and direction has to be taken into account. Additionally, the impact of large buildings, offshore platforms and other vessels, which may divert, shield and reflect the wind, is relevant. For the behaviour of vessels in dynamic mooring and structural analysis, the variations of the wind speed and direction in time also have to be considered. Assumptions used in marine engineering methods such as the use of standard wind profiles and spectra are outdated.
