Abstract:
A method of directing an anchored floating structure, comprising:anchoring the floating structure at a fore end of the floating structure; andadjusting at least one pivotal wind rudder provided at an aft end of the floating structure with respect to the direction of the wind such that the floating structure is directed against the direction of the waves in a stable manner due to force on the floating structure generated by the wind and the at least one wind rudder;wherein said adjusting comprises pivoting said at least one pivotal wind rudder so as to provide a force acting on the floating structure inverse in direction to the sum of forces on the floating structure transverse to the longitudinal centerline of the floating structure due to wind, waves and currents; andwherein said adjusting is carried out to direct the floating structure against the direction of the waves in a stable manner even when the directions of the wind, waves and currents are not the same.
