Steel Division
Whether in the Gulf of Mexico, in the North Sea or the Arctic, our thermomechanically rolled structural steels for the offshore industry are used worldwide. We deliver high-quality offshore structural steels for fixed and floating offshore platforms according to offshore standards EN 10225 (including NORSOK) and API as well as to a variety of other international standards and specifications.
Our offshore plates for the oil & gas industry are used worldwide under the harshest conditions. Living continuous development of new products to meet more stringent requirements, we are able to provide prequalified arctic steel for extremely low temperatures. Using toughcore® TMCP plates with extreme high toughness, you are able to increase the level of safety for your offshore structure up to 140 mm thickness.
Larger monopiles require higher unit weights in cylindrical and tapered pipe lengths. We achieve these weights by welding together two to three plates and call the new unit an XL plate. This highly efficient and innovative welding technique utilizes a four-wire submerged arc welding system capable of producing up to 60-ton unit weights.
These heavy units meet the growing requirements of offshore wind parks.
As structures and machines become larger, the stresses in the components increase. High-strength steels with minimum yield strengths of 700 MPa or even higher up to 1100 MPa are capable of supporting these higher stresses and simultaneously lead to a decrease in the weight of structural members.
Thermomechanically rolled high-strength fine-grained steels combine excellent toughness with a very low carbon content and the low carbon equivalent and for an optimized weldability.
Our shipbuilding steel plates in normal and high-strength grades are used in offshore applications, platform superstructures and for special ships in the oil and gas industries, such as floating production storage and offloading vessels (FPSO) and even stainless steel clad plates for icebreakers.
We offer a wide range of dimensions and grades with best workability for ship manufacture, especially for welding: steel grades up to FH 36 and plates up to 140 mm thick and 3,950 mm wide. High-strength shipbuilding plates are certified e.g. by ABS in FQ70 up to 101.6 mm (4").
In addition to supplying heavy plates, heads and cones, we produce specific pressed parts for the offshore industry. In a specially designed production process, we manufacture high-strength hot-formed components called chords for jack-up rigs. Additionally we offer extremely thick plates for gear racks.
