Arctic Steel for Sakhalin II
19 January 2005
Arctic application represents the highest Challenge for today's structural steel plates. Low design temeratures such as -40°C require steels showing good fracture toughness (CTOD) behaviour combined with high strength in higher thicknesses.
In order to meet this new set of steel properties, Dillinger huette developed a S450 Arctic steel which has been supplied more than 10,000 tons to the Sakhalin II project. A S355 variant with equakky low design and testing temperatures was supplied for the piles of the Kashagan Project. The development started some years ago with the delivery of Stell plates showing CTOD values at -20°C for the Canadian Sable project instead of the usually required -10°C for the North Sea.
Dillinger Huette feels best prepared for the new era of arctic energy projects.
Technically details will be published in our new Offshore Letter foreseen to appear in February.
