Ground Investigation at Port Talbot

Causeway Geotech have recently completed extensive onshore and nearshore ground investigation works at Port Talbot in South Wales. These works will inform the geotechnical design of a proposed new green energy hub for our valued client, Associated British Ports. Both our jack-up barges were equipped with dual purpose roto-sonic drilling rigs from Royal Eijkelkamp to successfully achieve excellent production for the marine campaign. Our team completed works ahead of the programme in a challenging and extensive scope. Despite the difficult ground conditions, the progress and quality of information returned were a testament to our approach. The combination of using optimum drilling methods, the most suitable rigs, and the highly skilled and trained ground investigation drillers helped in this regard. Working in collaboration with ABP and their design team, Mott MacDonald, the onshore works saw us agree scope adjustments on a proactive basis, replacing cable percussion boreholes with sonic drilling to overcome the challenges presented by the extremely dense anthropogenic strata. Having deployed two roto-sonic drilling rigs from our own land drilling fleet we were supported by an additional two from our trusted supply chain partners. This approach afforded the project team the benefit of applying the correct techniques to retrieve the best quality data while not compromising the overall programme.
