Bauer’s Dive Drill Method Nominated for bauma Innovation Award 2025
Securing the energy supply, protecting the oceans: With the innovative Dive Drill method, Bauer is setting new standards in the construction of offshore foundations. Whether in stormy seas or hard rock, thanks to this ultramodern method and a drilling rig developed in-house, offshore wind parks can be built safely and sustainably even under extreme conditions. The secret? Efficiency, precision and a clear focus on environmental protection. Securely anchored in the ocean This drilling rig specially developed by Bauer is controlled from a vessel. Thanks to low-vibration drilling, the impacts on the sensitive ecosystem are minimal – operating noise is scarcely perceptible even in the immediate vicinity of the drilling location. An additional environmental benefit: Biodegradable fluids are used in the hydraulic circuit. Temporary casings stabilize the borehole while the drilling tool crushes the material and carries it away as a pumpable slurry. Efficiency on the high seas Even when it comes to the energy supply for drilling rigs, Bauer is opening up new avenues: Electrohydraulic drives ensure maximum efficiency with minimum energy consumption and can be used flexibly on stationary or floating platforms. One highlight: To prepare the cement slurry for grouting the foundation elements, seawater was used instead of freshwater, which achieved another considerable reduction in logistics expenditure and made the method even more sustainable. A perfectly coordinated tool to assist the process: the ultramodern batch mixing plants from Bauer Maschinen subsidiary BAUER MAT Slurry Handling Systems. Towards a sustainable future “Our expertise in specialist foundation engineering combined with innovative technologies enables us to implement offshore projects efficiently and sustainably,” explained Harald Heinzelmann, managing director (COO) of Bauer Spezialtiefbau. “With our Dive Drill method, we create the basis for a groundbreaking use of renewable energies – safe, precise and resource-efficient.”
