TRT measurements in tidal seas offshore Taiwan for Jan de Nul

In autumn 2018, FIELAX has conducted TRT measurements offshore Taiwan for Jan de Nul. The data will be used to enlarge the knowledge base and optimize the planning for the big offshore wind farms Formosa and Changhua. More information about this project can be found at Jan de Nuls Website (https://www.jandenul.com/en/pressroom/press-releases/another-big-achievement-for-jan-de-nul-in-asia). The measurements were performed with our newly designed tripod for manual installation of a 6m thermal probe. The sensor string is installed by smooth vibration and vertical guiding into the sediment. With this probe, 22 TRT measurements can be determined simultaneously with minimum impact to the sub bottom layers. A heat pulse is released and TRT values are determined by mathematical inversion from the decay of the heat pulse. The result is a depth-resolved TRT profile of the undisturbed sediment with 22 evenly spaced values to a maximum depth of about 5,3m. More information can be found at www.fielax.de/heatflow. The measurements went very well thanks to support and knowledge of Jan de Nul and locals. Read more...

TRT measurements Off-/Near-/Inshore Holland – cooperation with MSH

This autumn, FIELAX has gathered data for two cable route projects with Marine Sampling Holland (www.marinesamplingholland.nl). We have measured a total of more than 100 profiles of temperature and TRT (thermal resistivity) data offshore Holland as well as in the Ijsselmeer. As the requirement was high resulotion profiling to a sub-bottom-depth of >6m, special coiled sensor tubes with a total length of 8m were manufactured. These have been successfully used with the mini-CPT. For some shallow-water locations near the shore, the requirement was the high resulotion profiling down to a sub-bottom-depth of 12m. To reach down to these depths, borehole drilling technology from Wiertsema & Partners (www.wiertsema.nl) was used along with a ‘standard VibroHeat’ sensor string (22 sensors, 3,5m length). Five cycles of boring/probing for each location were performed. The resulting overlapping temperature and TRT data were then used to create a combined 0-12m profile. More information about the method and further references can be found at www.fielax.de/heatflow. Read more...

Thank you for a fabulous OI China 2018! 谢谢!

Together with our exclusive representative in China, 青岛国科 (QDGK, Qingdao GuoKe) we had a great exhibition in 青岛 (Qingdao, China). We built new business contacts, developed new ideas and brought a lot of positive impressions with us. We would like to thank our partners QDGK, the OI China 2018 exhibition team and the funding of European Regional Development Fund: 谢谢! Read more...
