Offshore Structures
Wind loads affect offshore structures during construction, towing, and in service. They are a significant design factor, especially in the case of large compliant platforms such as guyed towers and tension leg platforms. This chapter contains information on wind loads on offshore structures of various types and on the treatment of dynamic effects on compliant structures. It briefly reviews a number of wind tunnel tests conducted for semisubmersible units and for a large guyed tower platform. Compliant offshore platforms are designed to experience significant motions under load. An advantage of compliance is that the forces of inertia due to the motion of the platform tend to counteract the external loads. Unlike wave motions, wind speed fluctuations in the atmospheric boundary layer are characterized by broadband spectra. For this reason, it has been surmised that wind‐induced dynamic amplification effects on compliant structures are significant.
