New Techniques for Bridge and Structure Inspection

Mon, 29 Sep 2014 11:27:45 GMT

“Combining Scanning Sonar, Laser Scanning and Mobile Mapping to Provide New Techniques for Bridge and Structure Inspection.”

By Tom Card, LandScope Engineering Ltd

Summary of paper:
With regards to bridges and other underwater structures, owners, operators and the civils industry are continually challenged to understand the structure and condition of assets below the water line. New techniques in 3D sonar are now enabling high resolution, high accuracy point clouds to be collected underwater. This presentation will discuss the challenges faced in designing data collection programmes, understand the value of combining such with traditional laser scan (LiDAR) point clouds and appreciate the advantages of this rich resource over more traditional underwater inspection techniques.

The benefits of online analysis of sound speed profiles during data acquisition

Mon, 06 Jan 2014 15:35:04 GMT

By Hydrographic surveyor - Morten Sølvsteen, Danish Geodata Agency

Presentation outline

The two major uses of the ”skeleton”

1) Line planning
Line planning for more efficient surveys.

2) On-line analysis of sound speed profiles during data acquisition
A method for analyzing overlapping areas in multibeam echosounder surveys is introduced. The method requires that the velocity of sound at the transducer is monitored during the survey.

The method applies the principle of least squares to determine the vertical offset and the bias of the swaths caused by insufficient knowledge of the velocity of sound in the water column below the transducer.

This presentation was given at the Teledyne RESON Underwater Technology Seminar in Copenhagen 2013.

Video paper: Pipeline surveying from a surface vessel in the Caspian sea

Mon, 25 Nov 2013 12:49:39 GMT

Surface Vessel Based Multibeam Pipeline Inspection

In a special collaboration between BP, Fugro Caspian and Teledyne RESON an unconventional approach was used to survey pipelines in the Caspian Sea. A vessel was outfitted with two pole mounts each equipped with a SeaBat 7125 SV2 using FP3. Teledyne PDS software was used to automatically detect and track the pipes in real time. A total of 710 km pipe was surveyed in just seven days. This presentation outlines the advanced technologies that were involved to collect such high resolution pipeline data.

Surveying in the most remote place in the world, Antarctica

Fri, 01 Nov 2013 14:41:45 GMT

Navigation data is poorly available in Antarctica. If navigational data is available it often dates back to the early 1900s with many lead line surveys. An initiative was undertaken by Stephen Wilkins of Xplore Expeditions to collect bathymetry with a multibeam SeaBat 7125-SV2 survey system making use of the sailing vessel Xplore. Together with Yoann Boulaire from SHOM, France and Fernando Landeta, hydrographic technician from Skyring Marine Chile, an IHO qualified survey was performed in Antarctica on an expedition sailing yacht.
