Checking the speed/time profile
Functionality level 1
Functionality level 2
Function
input information
Output information
1. Check set speeds
1.1.1 Record data and set
values
• Set speeds along the planned
track
• Load status/stability and ma
noeuvring behaviour of the ship
• Maximum voyage speed/engine
data
• Hydrographic and meteorologi
cal information (currents/ice,
wind/sea swell)
• Local speed restrictions
• Planned speed parameters (set speeds) in
relation to the influencing variables
1.1.2 Compare data and
set values
• Result information from 1.1.1
• For each track section: difference between
possible speed and planned set speed
1.1.3 Assess result of
comparison
• Result information from 1.1.2
• Assessment whether determined difference
from 1.1.2 is “positive” for each track section
(i.e. possible speed > planned set speed)
1.1.4 Provide result of
comparison
• Representation of track sections
for which planned set speed is
too high, and the respective
cause (result of 1.1.3)
• Provision of set/actual deviation, stating the
particular cause
2. Check passage and
arrival times
2.1.1 Record data and set
values
• Set speeds for each track sec
tion
• “Length” of track sections, i.e.
distances between any two way
points
• Set speeds and distances for all track sections,
taking correction information into account
2.1.2 Compare data and
set values
• Result information from 2.1.1
• Statement of compilation of amended values
for set speeds or distances
2.1.3 Assess result of
comparison
• Itemisation of track sections for
which distances or set speeds
have changed
• Decision as to the track sections for which new
calculations should be carried out
