“…One of the aims of the model test is to represent these load effects appropriately in the scaled model tests. This constitutes one of the important steps in the scaled model testing [6], including aspects such as new materials [7], site-specific estimates [8], and future monitoring strategies [9]. The readers are referred to further details of physical modelling in general and its applicability in [6].…”

Offshore wind turbines are a complex, dynamically sensitive structure due to their irregular mass and stiffness distribution, and complexity of the loading conditions they need to withstand. There are other challenges in particular locations such as typhoons, hurricanes, earthquakes, sea-bed currents, and tsunami. Because offshore wind turbines have stringent Serviceability Limit State (SLS) requirements and need to be installed in variable and often complex ground conditions, their foundation design is challenging. Foundation design must be robust due to the enormous cost of retrofitting in a challenging environment should any problem occur during the design lifetime. Traditionally, engineers use conventional types of foundation systems, such as shallow gravity-based foundations (GBF), suction caissons, or slender piles or monopiles, based on prior experience with designing such foundations for the oil and gas industry. For offshore wind turbines, however, new types of foundations are being considered for which neither prior experience nor guidelines exist. One of the major challenges is to develop a method to de-risk the life cycle of offshore wind turbines in diverse metocean and geological conditions. The paper, therefore, has the following aims: (a) provide an overview of the complexities and the common SLS performance requirements for offshore wind turbine; (b) discuss the use of physical modelling for verification and validation of innovative design concepts, taking into account all possible angles to de-risk the project; and (c) provide examples of applications in scaled model tests.

Offshore wind power is increasingly becoming a mainstream energy source, and efforts are underway toward their construction in seismic zones. An offshore wind farm consists of generation assets (turbines) and transmission assets (substations and cables). Wind turbines are dynamically sensitive systems due to the proximity of their resonant frequency to that of loads considered in their analyses. Such farms are considered lifeline systems and need to remain operational even after large earthquakes. This study aims to discuss hazard considerations involved in the resilience assessment of offshore wind farms in seismic regions. The complexity of design increases with larger turbines installed in deeper waters, resulting in different types of foundations. In addition, Tsunami inundation is shown to be an important consideration for nearshore turbines.
