In 2007 Smit Engineering as a subcontractor of MTHøjgaard pile drove and drilled 60 foundations for the Robin Rigg Offshore Wind Farm, located Solway Firth between Galloway and Cumbrian coasts in the Irish sea.
Construction is completed in September 2009. The foundations have been successfully installed from the jack-up barge Lisa A.
During this job DDC was standby with the Wirth PBA 815 with drill bit 2750 mm diameter. This PBA 815 is hydraulically driven by a Power pack and works with the reverse air lift drilling principal.
