Abstract: RAVE - "Research at alpha ventus" coordinates different projects connected to the German offshore test site "alpha ventus". One of these projects is GIGAWIND alpha ventus taking the OWEC support structures into focus. The main objectives in this field of structural design are foremost the reduction of both material and personal costs. This endeavour primarily requires a holistic view on the design process encompassing the following design aspects: Load modelling - analysis of multidirectional wave loads for the estimation of optimized sea state coefficients and correlation with wind loads. Fatigue - varying influence of manufacturing aspects represented by large safety factors. Corrosion - corrosion protection for offshore steel structures. Monitoring - reliable load monitoring at global and local components of the structure. Scour - development of new scour protection systems and local scour monitoring. Foundation - modelling of the load-carrying behaviour of driven offshore piles. Validation - Automated validation of general structural models. With the integration of separate computational tools into an easy operable simulation and design package with common interfaces the efforts focusing on the design process will be minimised. Overall objective of the project is to conceptualize and develop a holistic design concept for OWEC support structures, which is achieved in a modular approach in order that updated routines and further extensions can be easily implemented.
