We would like to wish all customers and friends of FIELAX a reflective Christmas season and all the best for 2021. At the end of the year we are happy to be able to donate again to some organizations:
The research vessel HEINCKE of the Alfred Wegener Institute is regularly sailing the North Sea and the North Atlantic. Temperature and salinity of the surface seawater is measured continuously during these voyages. FIELAX has been processing these data since 2015. So far, more than 220 voyages (incl. reprocessing of voyages since 2009) could be made available via the data repository Pangaea (https://www.pangaea.de/?q=heincke+tsg+). During Read more
In December 2019, a colorful mix of fruit trees was planted on the unpaved part of our yard. In the long term, this initiative aims to provide food, shelter and shade for employees, insects and birds.Only two years later the first harvest can already be looked forward to.
For many years, the thermal conductivities of sediments have been calculated at FIELAX from the data of special temperature measurements. For many applications, however, the thermal diffusivity is also of interest. Together with the University of Bremen it was investigated how the calculation of thermal diffusivity from temperature data in addition to thermal conductivity can be achieved or improved. As a result of this project, which was supported by the European Regional Development Fund (ERDF), a scientific publication was produced, which is available at https://doi.org/10.1007/s13137-021-00183-1.
Since December 2020 and ongoing, FIELAX provides thermal conductivity / thermal resistance measurements for cable routes for three wind zones in the Dutch North Sea to be connected by TenneT (offshore-energy.biz/tennet-picks-next-geosolutions-for-route-surveys-fugro-as-backup/). As a subcontractor to Next Geosolutions (nextgeosolutions.com), FIELAX conducts most of the surveys using our systems in combination with Next's Vibrocorer.
At shallow water depths / tidal flats / onshore, the VibroHeat method is not feasible. We are pleased to offer different adapted deployment methods with different geotechnical equipment in close cooperation with Marine Sampling Holland (marinesamplingholland.nl). Some nearshore and - so far - all onshore tests have been performed with the PushHeat system (a combination of a mini-CPT with a coiled thermal test rod; the picture shows one site on the beach on a stormy day). In 2021, we also expect to deploy downhole technology for onshore locations where a high-resolution TRT profile is required to depths greater than 10 meters. To reach these depths, multiple cycles of drilling/probing will be performed. More information on the methods and additional references can be found at www.fielax.de/en/what-is-heat-flow/.
