N2 - Multiple suction bucket foundations are a promising alternative to common foundations for offshore wind energy converters. Tensile loading of this type of foundation is expected to be crucial in the design process. This paper provides an overview over the existing analytical methods for determining the tensile bearing behaviour, describes their concepts and highlights the specific shortcomings. To evaluate the existing approaches, the results for a reference case are compared to numerical simulations with a mechanical-hydraulical coupled finite element model. It is found that the existing analytical methods are either inaccurate, only calculate the ultimate resistance rather than the load-displacement behaviour or are too complex to handle. Numerical or physical modelling are no factual long-term alternatives to an adequate analytical calculation method. Therefore, the demand for an improved analytical calculation method is evident. The idea and requirements of a new calculation procedure are introduced in this paper.
