What are average periods which moorings for fixed structures such as wave devices, must be left for soil/sediment to settle, I have a source stating 1-6 months but no good information to back this up.
I also wonder whether moorings are often installed in the winter when sea conditions are less...
This gives a review of wave device mooring systems, doesnt list them in relation to depth a seabed type, but gives you the key types.
