This paper presents a general uncertainty assessment in hydrodynamic testing of a floating wind turbine. A general uncertainty analysis is often carried out when the goal is to assess the sensitivity of the results to uncertainties in the input variables, regardless of whether the uncertainty is of systematic or random nature. The analyses are based on the 12MW INO WINDMOOR semisubmersible floating wind turbine. The assessment is carried out as a numerical study of the WINDMOOR hydrodynamic experiment [1]. A global simulation model of the experimental setup is established in the simulation framework SIMA. The propagation of uncertainty is assessed using two different approaches: The classical Taylor Series Method (TSM) and the Monte Carlo Method (MCM). Specifically, the uncertainties in the mooring system and their effects on the mooring line tension and platform responses are investigated. The assessment is performed for a range of standard uncertainties in the input variables, and the results from the two methods of assessing the uncertainty are compared.
