Alongside HDI this month for the successful completion of landfall works for the NeuConnect interconnector project. Once connected, this will create the first ever direct power link between Germany and the United Kingdom.
Drilling through essentially silty clay soils, 3 parallel 420-metre-long HDD landfall crossings were completed to house DN400 HDPE ducts where the subsea cables will transition to the onshore underground cables in Kent, England.
HDI commissioned OPTIMUM to support them with the landfall on the UK side both before and during the drilling operations: definition of a geotechnical base model, hydrofracture analysis modelling, as well as validation / adjustment of working methods, drilling tools and risk mitigation procedures. Ballast calculations ahead of time minimised pipe/ground friction, ensuring the integrity and longevity of the installation. OPTIMUM engineers then carried out a G3 mission, monitoring the HDD works both remotely and onsite.
Great to be part of another trenchless first.
