4.10.3 Pipe Route Creation
Figure 4-69
Pipe route creation parameters
From the found pipe parts a pipe route can be generated.
Maximum pipe parts used in routing
Maximum valid pipe parts that will pass to the pipe routing.
When a patch (25 pings) is processed several pipe parts are tracked,
qualified and filtered. When for example 6 valid pipe parts are detected
in a patch and ‘Maximum pipe parts used in routing’ is set to 3 only the
best three pipe parts are passed to the pipe routing computation.
Join segments test
When the distance between two pipe routes is shorter than the
‘Gap
length’ the two pipe routes will become one pipe route.
4.10.4 Pipe Steering
Figure 4-70
Pipe steering parameters
At the start the
Steering mode
has to be set,
Horizontal
or
Flex
steering.
The settings for the steering will not be changed during the time of the
Steering delay
. This delay is defined as the number of patches of 25
pings. At the moment the size of the patch cannot be modified. For
instance, if the ‘Steering delay’ is set on 5 then the SeaBat UI will wait
until the 5*25 pings is surveyed before, if necessary, the settings for the
horizontal or flex steering are changed.
The setting for the steering is changed by the SeaBat UI when the
difference (in degrees) between the horizontal steering or angle of the flex
steering and the angle of the detected pipe in PDS2000 is more than the
Steering difference
.
When more pipes or pipe parts are detected the SeaBat UI will take an
average of the pipe (parts) positions to calculate a steering angle. The
pipe with the best quality of detections will have a bigger weight in the
average calculation. With this situation it is possible that the steering is
not always on the main pipe which has to be tracked.
When horizontal steering is selected the SeaBat UI will change the
horizon steering in the RESON SeaBat 7k sonar when the SeaBat UI
calculates that it is needed.
The Flex mode has to be
selected in the RESON
SeaBat 7k, before the flex
steering can work.
When flex steering is selected the SeaBat UI will change the angle of the
center beam of the flex mode in the RESON SeaBat 7k sonar when the
SeaBat UI calculates that it is needed. The width of the flex mode and the
settings of the flex mode will not be changed.
