Polyamide and floating wind turbine moorings

Among the options being explored for the mooring of future floating wind turbines is a semi-tensioned configuration with polyamide lines to dampen the dynamics transmitted to the float and reduce the footprint on the ground. As little is known about the long-term behaviour of this type of synthetic fibre, qualifying it for an operating life of 20 to 25 years is a major challenge. To meet this need expressed by the sector, the MONAMOOR project was launched in 2020 to gain a better understanding of the ageing mechanisms of these synthetic fibres, design and adapt modelling tools, and test monitoring instruments for the long-term behaviour and the reliability of this type of moorings.

This project is coming to an end, so a final webinar was held on 30 November 2023.

The detailed programme was as below:
