Offshore plates

Applications under the harshest conditions

We deliver high-quality offshore structural steels and thermomechanically rolled shipbuilding plates for drilling platforms, oil platforms and jack-up rigs. These steels are also used in foundations for offshore wind parks and floating production storage and offloading vessels (FPSOs). In addition, we are in a position to produce chords for the feet of jack-up rigs. We supply pre-qualified materials with plate thicknesses of up to 80 mm and CTOD values down to -40 °C for applications in arctic regions (arctic steel). Our thermomechanically rolled offshore plates are characterized by a high degree of toughness and excellent weldability. The low degree of cold cracking and high degree of toughness in the welding seam make it possible for us to guarantee the highest safety standards in welded structures.
