This paper presents an active control dedicated to the positioning of vertical offshore structures. The trajectory planning and the closed loop system use a convenient model given by the Bernoulli's historical cable equation, completed with a damping factor, that linearly depends on the structure speed. Its solution is directly used in the control design, providing an extension to previous works on control of heavy chains and offshore structures.
