Moorings Fact Sheet

Moorings

Floating offshore renewable energy systems have several advantages: higher wind and wave resources, technically unlimited water depth, better adaptability to soil types… However, they must limit their dynamics for a number of reasons:

  • efficiency (e.g., reduction in wind turbine performance if the floating structure movements are too severe),
  • safety (e.g., disruption of vessel traffic),
  • robustness and technical and economic viability (e.g., pulling out the export electric cable, overdesigning costs).

Developing reliable and robust mooring lines is therefore essential. To do this, two criteria must be taken into account: limiting the amplitude of the forces and resisting maximum loads over the life of a farm. France Énergies Marines developed this Fact Sheet to describe the different moorings systems used for offshore renewable energy systems, and compare their advantages and limitations.
