1. A method of repositioning a floating offshore wind turbine located at a current offshore position and having rotor blades rotating in a rotor blade plane, the method comprising:
measuring a first value of a variability of a load related to a first location at the wind turbine;
measuring a second value of a variability of a load related to a second location at the wind turbine;
comparing the first value with the second value; and
moving the wind turbine along a direction depending on the comparison;
wherein comparing the first value with the second value comprises assessing whether an absolute value of a difference between the first value and the second value is greater than a threshold; and moving the wind turbine comprises to move the wind turbine only if the absolute value of the difference is greater than the threshold.
