The invention relates to a system for tracking a position of offshore structures, comprising cameras and a control device, wherein the system is configured to obtain images of the structures, to correlate object features of the structures in the images with corresponding model features in computer models of the structures and to repeatedly determine the position of the structures in order to account for relative movements between a reference and the cameras and/or the structures. The invention further relates to a method for tracking a position of offshore structures using cameras, comprising repeatedly determining the position of the structures, wherein each repetition of determining comprises the steps of obtaining images of the structures, correlating object features with corresponding model features and using the correlated features to determine a relative position of the structures with respect to a reference. The invention further relates to a method for the placement of a first offshore structure on a second offshore structure, comprising repeating the steps of tracking a relative position between the structures and of moving the structures.
