In partnership with Marine Sampling Holland and Wiertsema & Partners, we have broadened our portfolio of HeatFlow measurements. The well proven technology of in-situ measurements of thermal conductivity, thermal diffusivity, and thermal capacity can now be used onshore at practically unlimited depth. Using the drilling technology of Wiertsema & Partners, the system can be brought down to the desired depth and measure these thermal parameters up to 5m downwards. This unique method was used at three locations onshore Eemshaven in order to determine the thermal properties of the sediments at absolute depths of 3-7 m. The results will be used for a safe planning of a power cable crossing.
