Once positioned subsea, the ROV can determine the heading to verify the structure orientation.
After landing, the ROV uses the Bullseye to confirm that the angle of the structure is within acceptable limits.
An optional ROV docking probe interface, compliant with ISO 136288:2002(E), is also available.
