Wind Chill Analysis
The purpose of Wind Chill Index (WCI) analysis is to evaluate the Wind Chill Index (WCI) for outdoor working areas, which must fulfil applicable requirements for operation.
The CFD tool FLACS is used in these analyses, where a 3D model of the installation is made and ventilations simulations are run for relevant wind conditions. The simulation results are combined with probabilities of the wind conditions in order to evaluate fulfilment of requirements (e.g. not to exceed WCI = 1000 W/m2 in more than 2% of the time). WCI analysis is input to outdoor operation analysis.
Pecentage of wind chill above 1000 W/m2 for a horizontal plane of an offshore platform (NORSOK requirement is 2%)
