Mooring line for wind turbine model

[anders.sparen]

Hello,

I am construction a floating wind turbine model which is going to be used in a wave tank experiment this fall. Currently I'm looking for a mooring line for this model.

The line will go from the wind turbin down to the bassin floor, where it will go through a pulley and back up to the surface. Above water it will be connected to a spring system which models the stiffness of the mooring line.

The mooring line has should have the following characteristics:
- Approximately linear relationship between force and elongation in the area 0-50 kg tension.
- Very little or none elongation with time for a given force (low creep?)
- Be able to be bended of in a pulley of unknown size, angle approximately 100 degrees.
- Good against corrosion.

Does anyone have any tips?

I am currently considering:
- monofilament steel wire
- Carbon fiber wire
- Fishing line


Best regards

Specta fibers might work well.

Or maybe a thin wire rope like that sold on fishing tackle shops for leader material.
