Abstract: In recent years modern experimental and analytical techniques for estimating wind effects have increasingly been applied to compliant offshore structures. The six papers included in this book are concerned with various aspects and applications of these techniques. Comparisons are reported between aerodynamic forces and moments measured in the wind tunnel and their counterparts as calculated in accordance with rules issued by classification societies, professional associations, or code authorities. It is noted that in most cases these rules yield conservative results, but that this is not always the case. Various methodologies for obtaining and using wind tunnel data are discussed, and techniques are reported for measuring wind and wave effects simultaneously. It is noted that in the present state of the art laboratory tests cannot achieve the combination of large Reynolds numbers (of the order of one million) and small Keulegan-Carpenter numbers (of the order of unity) that is typical of tension leg platform columns. Such tests can therefore provide incorrect estimates of the hydrodynamic damping inherent in full-scale surge motions and, consequently, of the wind-induced dynamic effects on the prototype structure.
