A method for coordinating a floating wind turbine installation. The wind turbine installation includes a buoyant body (), a tower () arranged over the buoyant body, a generator () mounted on the tower which is rotatable in relation to the wind direction and fitted with a wind rotor (), and an anchor line arrangement () connected to anchors or anchor points on the sea bed. Static heeling, &#x3c6;, at full wind load on the wind turbine is as low as possible, but preferably less than 8 degrees, and all eigenperiods for the installation are outside the waves' period range. The eigenperiod in pitch, T(roll, T), is preferably less than 80% of the Teigenperiod in heave. Moreover, the ratio between Tand Tis not close to 0.5 or 1.
