Course description

Teledyne RESON Training
Comprehensive SeaBat / Software / Boat Training (5 days)
Course description
This course covers the full hydrographic workflow from SeaBat
installation and interfacing, to calibration and data collection,
and finally data processing and deliverables. Providing the
theoretical background to the latest multibeam technology, how
it relates to data quality and describes the survey techniques
which ensure optimal performance. Data examples will be
included showing high quality results together with examples of
how operation, integration and environmental issues may
manifest themselves in the final product. A survey vessel will be
outfitted with a Teledyne RESON SeaBat and the latest Feature
Pack for hands-on training including multibeam patch test, data
interfacing, and general survey training. Delegates will be trained
with their preferred software package for hands-on data acquisition and data processing. This 5 day course is well balanced
between classroom theory, hands-on boat training and software
training. All experienced and new SeaBat users are invited to
attend.
Multibeam Sonar Principles
Multibeam terminology; transducer functions; sonar processing functions; geometry; multibeam data rates;
survey coverage; properties of sound in water; survey deliverables.
Multibeam Sonar Technology
Multibeam sonar construction; electronics; understanding the ping cycle; transmit and receive functions;
range and depth resolutions.
Beam forming Principles
Transmit and receive beam-forming principles; beam forming patterns & advanced modes (FlexMode);
beam focussing; bottom detection. How these factors affect data quality.
FM Technology
FM pulse; signal processing; implementation in SeaBats.
Multibeam Data Types
Understanding raw data; beam data (water column backscatter); bathymetry; Snippets backscatter; sidescan backscatter. Applications for each are discussed.
Principles of Operation & Tuning
Tuning a multibeam system for optimal quality of results, discussing the fundamental settings: range;
power; pulse length; gain; filters and how they affect the quality of results. ‘
Multibeam System Integration
Geo-referencing multibeam data: time synchronisation; motion compensation; sensor data rates; installations; reference points; offsets and alignments; tolerances.
Multibeam Calibration Principles
Overview of multibeam applications and use of data types; pipeline surveys, route surveys; integration with
surface laser; installation surveys; monitoring surveys (scouring, catenaries). Forward looking applications:
ROV intervention; leak detection
Survey Quality Standards
Meeting survey specifications; numerical determination of data quality; total propagated uncertainty (TPU);
error sources, data density.
Data Examples
Understanding artefacts and their sources; motion artefacts; installation related artefacts; noise sources;
correctable problems; non-correctable problems.
Multibeam Applications
Overview of multibeam applications and use of data types; pipeline surveys, route surveys; integration with
surface laser; installation surveys; monitoring surveys (scouring, catenaries). Forward looking applications:
ROV intervention; leak detection.
Hands-on Data Acquisition
Live Data Acquisition and system integration with preferred software package (availability may be subject
to change). Project setup; data acquisition displays and QC of data in realtime; point could data; grid data;
online filtering.
Hands-on SeaBat Operation
Using fully equipped Survey Vessel for SeaBat interfacing, operation, sonar maintenance, patch test; data
collection.
Hands-on Data Processing
Data processing with preferred package (availability may be subject to change). E.g. Data cleaning; grid
modelling; CUBE filtering; Backscatter (GeoCoder); data deliverables; import/export sonar and auxiliary
data; SVP processing.
