ELASTMOOR - Elastic mooring systems for wave energy converters

The project aims to improve the knowledge of using elastic mooring lines for wave energy applications. It will be achieved by collecting data from (i) laboratory testing of rubber, polyester and nylon lines, and of the coupled system of mooring and floater in an ocean basin test, and (ii) full-scale field tests of Waves4Power’s wave energy converter. A taut spread mooring configuration designed by Seaflex is used by Waves4Power. The results from the laboratory tests will be used for (iii) full-scale field tests of a mooring made of rubber, polyester and nylon lines to be conducted in Portugal, and (iv) the development of constitutive models which will be implemented in an in-house mooring dynamics numerical model. The simulation tool will be used to analyse the durability of mooring systems. Reliability analysis will be used to consider the statistical variability in parameters that have an influence on fatigue life.
