The challenges faced by the offshore industry are typified by extreme working locations subject to arctic temperatures and enormous mechanical and dynamic loads. The demands made on the design and materials selected for drilling rigs and wind turbines are also correspondingly high. Sif Group B.V., of the Netherlands, is one of the most important fabricators of steel tubular elements for the construction of oil and gas platforms and the foundations of offshore wind farms. The company has for decades used heavy plates sourced from Dillinger. This also applies, for example, to the jacket structure for the Edvard Grieg oil and gas platform and to the monopiles for the 150 wind turbines that make up Gemini, one of the world's largest offshore wind farms. For these projects alone, Sif used more than 100,000 tonnes of Dillinger steel, primarily thermomechanically (TM) rolled plates.
