POLYAMOOR

Durable and flexible polyamide moorings for marine renewable energies

Duration : 3 years

Project description

Anchoring systems used for floating wind turbines differ significantly from those used in the oil & gas sector due to elevated dynamics in shallow waters. The challenge is to be able to maintain a floating foundation in an extreme environment by limiting the forces transmitted by the mooring lines as well as limiting the maximum offset of the foundation to which the export cable is connected. One envisaged solution is to use nylon mooring lines capable of absorbing the involved forces but whose behavior is highly non-linear and poorly understood in cases of long service life.
POLYAMOOR project proposes to closely characterize the forces and long-term behavior of nylon mooring lines in order to identify their added value and to update certification recommendations.

Objectives

  • Characterizing, modeling and optimizing polyamide fiber anchor lines for the operation of pilot and/or commercial marine renewable energies (MRE) farms
  • Modeling and dimensioning MRE permanent anchoring systems (floating wind turbine or wave motor) based on polyamide cable.
