Design of composite material for cost effective large scale production of components for floating offshore structures

Abstract

The design and testing of composite point absorbers under slamming load is the central theme in this paper. The research is situated within the SEEWEC project which was launched at the end of 2005 in the Sixth Framework of the European Union. The SEEWEC stands for the sustainable economically efficient wave energy converter. First, the energy situation in Europe is discussed to explain the objective of these point absorbers within this research. Next, a small filament winding machine has been designed to produce these point absorbers on the laboratory scale. Also, a set-up for laboratory scale slamming tests was designed and built. Several test samples were produced on the winding machine and tested on the slamming set-up. First, a cone was tested as a reference case. Validation of this case followed suit. Next, a deformable and a non-deformable cylinder were compared. Finally, a possible point absorber was tested. Finite element analysis (FEA) calculations were conducted and computational fluid dynamics (CFD) simulations are initiated.
