In the Vessel shape section it is possible to select the vessel shape or to get the vessel
shape from a file.
Vessel shape The vessel shapes supported are ship, rig and jackup.
From file Input of vessel shape from file, see separate section.
Vessel opacity A percentage scaling of the opacity of the vessel shape on the
screen.
In the Navigation ref. point (NRP) section, the distance between AP and NRP is
defined.
AP to NRP The distance from AP to NRP [m]. The Navigation Reference
Point location (NRP) is the reference point for all measurements
in the system. The recommended used NRP is the vessel CG or
rotation centre.
4.4.1.2 Vessel shape
For later configuration of sensor and monitoring point locations on the vessel, it is an
advantage that the vessel is of the same shape as the vessel where the system is
installed. The background vessel is scaled on the screen to be equal to the installed
vessel. By moving the PC mouse around on the vessel, the coordinates (x,y,z) will be
shown in full scale. For later configuration of sensors and monitoring points, just place
the PC mouse on the screen on the spot where the sensor or monitoring point is wanted
and the coordinates for this point are then automatically defined.
It is possible to select a pre-defined shape of the vessel, which is ship, rig or jackup, or
to define the shape from
File as a User Bitmap or User Text with 2D description of the
vessel.
To input Vessel shape from file as user text, proceed as follows:
1 When generating the vessel image from file, the following data format and
structure is to be used:
-
The vessel data have to be in an ASCII file generated by Excel, Notepad
or similar tools.
-
The file head includes LOA, Overall width, Overall height and Aft to AP
data in metres.
-
Profile data in X and Z coordinates in metres. The first coordinate has to
be for AP and start with 0.00 and the last coordinate has also to be AP
end with 0.00.
-
The top view data in X and Y coordinates in metres. The first coordinate
has to be for the aftermost point on the vessel and on the centre line. The
last coordinate has to be the foremost point on the vessel and on the
centre line. Only data for the starboard side of the vessel should be input
since a vessel is symmetric along the centre line.
