Very large floating structures (VLFS) are more and more employed by a number of countries in creating land space from the ocean. These “swimming islands” are of pontoontype and benefit from high stability, low manufacturing costs, and easy maintenance. Owing to their much larger dimensions in length than in depth, the VLFS are relatively flexible and, thus, VLFS have to be robustly designed against waveinduced deformations and stresses. As such a reliability analysis involves many uncertainties, efficient methods have to be developed that allow for both the modelling of uncertain behaviour and the handling of the computational complexity.
In this project, the main objective focuses on the development and implementation of a prototype for the hydro elastic analysis of VLFS. Therefore, stochastic finite elements are subject of choice for the planned reliability analysis over huge sets of different structural properties, while sophisticated techniques of modern grid computing should tackle the computational problem of such complex parameter studies.
