X-Range (Fp3)• X-Range is FM modulation• 20-25% longer range• No loss of range resolution• Noise suppression effect (better Quality data)
![Page 28: Seabat Multibeam systems latest technologies and applications](https://reader038.fdocuments.in/reader038/viewer/2022102610/5569365cd8b42add468b51cb/html5/thumbnails/28.jpg)
PAGE 28
X-Range• Extended range (FM)
• Provides increased range (increasing the energy)
• Transmit a very long pulse (typically 100-1000 times longer
• Using long pulses degrade resolution
• Use pulse compression to regain resolution
• Improved Noise immunity (by pulse compression)
![Page 29: Seabat Multibeam systems latest technologies and applications](https://reader038.fdocuments.in/reader038/viewer/2022102610/5569365cd8b42add468b51cb/html5/thumbnails/29.jpg)

• Tracker in FP4– Constant swath width– Tilted Heads & Dual Heads – It is now possible to disable certain Tracker control settings for
advanced users who wish to remain in control of certain settings

Multi-Detect
![Page 40: Seabat Multibeam systems latest technologies and applications](https://reader038.fdocuments.in/reader038/viewer/2022102610/5569365cd8b42add468b51cb/html5/thumbnails/40.jpg)
PAGE 40
Multi-Detect• Multiple detections within each beam, including the full water
column
• Capture enhanced detail from a single survey line over a complex feature
• Ensure that full detail is captured of any object in the water column
• Up to five detections may occur anywhere within each beam
• Note that Multi-Detect is not equivalent to multiple soundings across a beam footprint on the seabed
![Page 41: Seabat Multibeam systems latest technologies and applications](https://reader038.fdocuments.in/reader038/viewer/2022102610/5569365cd8b42add468b51cb/html5/thumbnails/41.jpg)
PAGE 41
Multi-Detect – An Advanced Tool• The surveyor controls the sensitivity of the Multi-Detect
algorithm using three controls:
• Object Size (Sensitivity): increasing this results in more detections on smaller objects. Decreasing it results in fewer detections and only on larger objects.
• Amplitude Sensitivity: increasing this causes more objects to be detected
• Max Detections: this control is used to limit the number of detections output for each beam to five

Pipe detection in the swath• Detection algorithm initially calculates top of pipe positions• BDA searches for detections in vicinity of pipe• Pipe detection algorithm automatically matches pipe position• Pipe position for next ping is initialised from previous pings• Pipe needs to be found several times at (almost) same position
in swath• Several pipe detections creates a pipe section
![Page 55: Seabat Multibeam systems latest technologies and applications](https://reader038.fdocuments.in/reader038/viewer/2022102610/5569365cd8b42add468b51cb/html5/thumbnails/55.jpg)

5 points output
•Top of pipe – Top of inserted pipe
•Points left/right from pipe– At distance of half diameter from pipe
•Mean Seabed at user defined offset at each side from top of pipe
•Points are defined from the MB data points in the swath (not from DTM)
•The 5 points are exported in 7k record as a 5 points string (ID 2004) •Format available for software packages
![Page 56: Seabat Multibeam systems latest technologies and applications](https://reader038.fdocuments.in/reader038/viewer/2022102610/5569365cd8b42add468b51cb/html5/thumbnails/56.jpg)

Detection of pipe in Swath settings• Diameter of pipe• Maximum Free Span (m) and
detection threshold– Maximum and minimum
distance from seafloor to detect pipe
• Statistic Threshold – Finds standard deviation of an
area around the pipe.– Higher values allow more
deviation
• Filters can be used to omit data with bad quality tests

Pipe steering Steers the swath towards the
pipe. Steers either full swath or
flex part of the swath.
Steering difference– Swath will only steer after a
change larger than the difference set
Steering delay– Difference has to occur at a
number of sequential swaths
![Page 59: Seabat Multibeam systems latest technologies and applications](https://reader038.fdocuments.in/reader038/viewer/2022102610/5569365cd8b42add468b51cb/html5/thumbnails/59.jpg)

What if?• Two or more pipes are followed at the same time?
– More than one pipe can be followed at the same time– Helmsman will show all pipes and select best possible position relative
to multibeam.
• Pipe changes diameter?– The algorithm also allows changes from the diameter
• Pipe is buried under seafloor– The MB system is not able to look beneath the seafloor.– When the pipe shows again it will:
• Continue the pipe when the gap is small enough• Create a new pipenumber when gap is too large
![Page 60: Seabat Multibeam systems latest technologies and applications](https://reader038.fdocuments.in/reader038/viewer/2022102610/5569365cd8b42add468b51cb/html5/thumbnails/60.jpg)
