We are delighted to introduce the brand new Datem Thermal Conductivity Cone for use on Neptune 5000 CPT Systems. The Cone will enable fast, in-situ measurements of thermal conductivity of subsea soils. Typically the system would be used to determine the heat transfer rate through soils around proposed subsea power cable routes. The Thermal Conductivity Cone is built with a combination of Titanium & high performance stainless steel.


It features a 5cm² Cone Penetrometer incorporating an off-axis thermal conductivity probe. This arrangement ensures that the CPT data is still valid and unaffected by the additional thermal conductivity system. Heat is generated by a built-in calibrated variable power heater.


Temperature measurements are taken by a calibrated high-precision sensor and the system provides real-time display of the temperature and initial calculation for thermal conductivity, while recording data for further analysis. CMS-Geotech  will be offering the Thermal Conductivity Sensor in conjunction with our Neptune 5000 CPT System either as a stand alone solution or as part of a complete package of Geotech support services.


The Cone is undergoing sea trials through May and the first systems should be available in the early Autumn.
