About the seminar
Over 60 Chinese surveyors, engineers and survey managers attended a GeoSwath
product seminar in Qingdao, Shandong Province, China 11th to 13th March 2009. The
attendees came from all over China to learn about the capabilities of the GeoSwath
wide swath bathymetry and side-scan sonar from GeoAcoustics Ltd of Great Yarmouth,
UK - A Kongsberg Maritime company. Live demonstrations were followed by lectures
on the sonar theory and best survey practice and expert tips were given on processing
survey data using the GeoSwath Plus software.
The Qingdao seminar was organised by Mike Zang of China-ORES Ltd, GeoAcoustics'
agent in China, and lectures were given by Dr. Tom Hiller, Product Manager at GeoAcoustics
Ltd. China-ORES Ltd of Qingdao is headed by Professor Tang Bao Jue. Professor Tang
was awarded GeoAcoustics' top agent prize in both 2007 and 2008.
The seminar included data collection using a local boat in Jaiazhou Bay. The
survey area varied between 3m and 25m depth and demonstrated the GeoSwath's wide
swath capability in shallow water environments. Clients could also see the advantages
of the simultaneous bathymetry and side scan data collected by the GeoSwath. A day
in the classroom covering the GeoSwath interferometric sonar theory was followed
by live processing and calibration of the collected data and a master class on survey
practice. Mike did a great job doing a live translation of the lectures for the
GeoSwath in China
More than 25 GeoSwath systems are now operational in China. These are working
on projects such as river navigation, coastal mapping, dredge works, port surveys,
marine construction and dam monitoring. An example of the GeoSwath's success in
China is its use in national hydrographic mapping projects: recently the State Ocean
Administration (SOA) East Sea Branch in Shanghai celebrated passing 75,000 line-km
of GeoSwath survey for China's National Project 908, a major national coastal and
environmental mapping initiative. SOA East Sea Branch now operates two GeoSwath
systems out of Shanghai, while China's National Marine Environmental Monitoring
Centre in Dalian is approaching 50,000 line-km completed with their GeoSwath sonars.
