About us
Prime Drilling GmbH was founded in 1999 and has specialised in the development and manufacture of modern horizontal drilling rigs (HDD – Horizontal Directional Drilling). At its plant in Wenden in the Sauerland region, this mid-sized family-owned company produces horizontal drilling rigs and components on 4,000 m² of production and 800 m² of office space, including compact drilling rigs, horizontal drilling rigs with pull forces up to 600 t, MDD rigs (Multifunctional Directional Drilling) for coal seam gas degasification, bentonite pump systems and the Prime Pipe Pusher for pipe pull-in with 400 to 1,000 t of pull/push force. Every rig is designed and built to customer requirements; the processes include design, structural steel fabrication, assembly as well as worldwide service, remote maintenance, training and spare parts supply from its own warehouse. In addition to steel, HDPE pipes are also used for pipeline applications. The rigs are deployed on all continents, including Australia, Antarctica, Africa and Brazil. Customers include pipeline contractors and water suppliers; used HDD rigs are also brokered.
