Rough conditions, high construction costsOffshore wind turbines are invariably installed in areas with high winds, often combined with rough sea conditions. All the materials and solutions deployed must therefore be of the highest quality, robust and able to withstand extreme weather.
Improving durability even in harsh environmental conditionsOffshore structures require materials that can withstand harsh environmental conditions such as high corrosion, variable temperatures and fierce storms. Everything from frame structures to boat landings and service decks must demonstrate exceptional durability and strength.
Tubes for installation as well as for windmillsInstalling wind turbines and rotors at more than 100 m height above sea level and in ever-increasing sizes and water depths is particularly challenging. It primarily uses jack-up barges which feature legs to lift themselves from the seabed, and cranes capable of lifting hundreds of tons.
Supporting the market around the worldNumerous Vallourec customers around the world are already reaping the benefits of its robust and long-lasting steel tubes for their offshore wind installations. And now, we are even supplying equipment to support the development of the rapidly emerging floating wind market. Equinor’s Hywind Tampen 88-MW floating wind power project, for example, is helping the sector take a huge leap forward, and Vallourec’s seamless hot formed hollow sections are playing a part. Hywind Tampen is intended to provide electricity for the Snorre and Gullfaks offshore field operations in the Norwegian North Sea, and will be the world’s first floating wind farm to power offshore oil and gas platforms.
Auxence Gros-BorotAuxence Gros-Borot joined Vallourec in 2018 as Marketing Manager for Renewables, assuming the role of Strategic Marketing Manager for the company's ETO (Energy Transition Opportunities) organization in 2020. A graduate of the prestigious engineering school Mines ParisTech, he began his career in offshore wind as a marketing analyst at AREVA Wind. This role, which he performed for 5 years, also covered the Group's other renewable and decarbonized energies: biomass, energy storage, concentrated solar power and the back-end nuclear cycle. Auxence has also worked in a consulting role on power-to-gas hydrogen projects.
Stephan ScherfStephan Scherf is a civil and welding engineer, who joined Vallourec in 2011. After working as Technical Sales and Product/Project Manager for Offshore Construction Projects Worldwide, in 2018 he joined the EA Industry Sales Department as Sales Manager and Team Leader of Global On- and Offshore Construction Projects. His role is to enhance Vallourec's Offshore Wind business, developing new contacts and synergies to promote new innovative products and solutions.
