Abstract: The present invention relates to a control system and a corresponding method suitable for controlling a gangway structure gangway, crane or similar suitable for transferring personnel or goods to or from a floating structure such as a sea vessel relative to a fixed or moving landing point. The system including global position measurement of the position of the floating structure and the position of the landing point, and thus a first relative position between the floating structure and the landing point, and a control unit configured to move the gangway relative to the landing point. The system also includes a local position measurement unit positioned at or in relation to the distal end of the gangway being configured to measure a second relative position between the landing point and the gangway distal end, the local position measurement unit being connected to the control system unit so as to communicate the second relative position to the control system unit.

Abstract: A gangway includes a distal end on which an end effector unit is attached. The end effector unit has an outer surface at least a certain portion of which is adapted to be in contact with an installation, wherein a movement of a rotatable element in the end effector unit corresponds to a movement of the distal end with respect to a reference point on the installation when the end effector unit is in contact with the installation, the movement of the distal end being at least along one of the axes related to the installation. A method for repositioning a gangway to a desired position on an installation or a target structure. A vessel or a watercraft includes the gangway and an installation includes the gangway. A computer software product implements method steps herein disclosed.
