Input information 
Output information 
3.2 Determine maximum 
transverse deviations 
3.2.1 Record input data 
• Set track, i.e. way points, joining 
polygon as well as planned ma 
noeuvre at course changing 
points (turning radius) 
• Manoeuvring capabilities 
• Dimensions and “safety re 
quirement’ of ship 
• Traffic restrictions along the set 
track (eg TSSs) 
• Draught/water depth 
• Hydrographic data (current 
conditions) 
• Passage distances to be ob 
served 
• Accuracy of the sensor technol 
ogy available 
• Collection of the necessary input data for determining 
the maximum transverse deviation 
3.2.2 Evaluate data 
• Output information from 3.2.1 
• Maximum transverse deviation for each track section, 
defined width of ‘track confinement" 
3.2.3 Provide set data 
• Output information from 3.2,2 
• Representation of the maximum transverse deviations, 
calculated on the set track, for the user 
• Storage of the maximum transverse deviation for fur 
ther processing 
4. Determine manoeu 
vring limits 
4.1 Establish maximum 
ROT 
4.1.1 Record input data 
• Manoeuvring capabilities 
• Load/stability 
• Set speeds 
• Set track and transverse devia 
tions 
• Necessary influencing parameters for determining the 
maximum ROT 
4.1.2 Evaluate data 
• Output information from 4.1.1 
• Maximum value for ROT, differentiated under certain 
circumstances according to track sections 
4.1.3 Provide set data 
• Output information from 4.1.2 
• Representation of maximum ROT for the user 
• Storage of ROT for further processing
