Installation Manual

TECHNICAL NOTE 2
Target installation
Key to the operation of the Radascan system is the correct installation of targets. Please
follow the guidelines given below when installing targets on the rig.
Once the targets are installed, their relative positions can be automatically surveyed by the
system.
Installation tips
• Targets should be placed in positions where the sensor can see them while the vessel is
within the expected working area. Consider vertical position as well as horizontal.
• The sensor beam should not strike a flat target at an angle of more than 45 degrees to the
target surface.
• Targets should be positioned with unequal spacing between them – this helps the system
to distinguish between specific targets. For example, with a typical mooring distance of 40-
80m using three targets, suitable spacings between the targets would be 10m and 20m –
giving a total spread of 30m.
