Offshore wind turbines spend their whole lives out at sea, where they face two big challenges: corrosion (metal slowly rusting in seawater) and fatigue (metal weakening from repeated bending and shaking caused by waves and wind). Right now, engineers estimate how long turbine parts will last by using simple “correction factors.” The problem is that these factors come from tests done in perfect laboratory conditions—not in the harsh, constantly changing ocean environment. This project aims to build a computer model that can predict how long welded metal joints in a wind turbine will survive when exposed to both real-world corrosion and real-world repeated loading.
The study looks at:
• how the sea environment accelerates rusting,
• how waves, wind, and turbine motion affect the metal, and
• how welded parts behave differently from regular steel. By understanding how all these pieces interact, the project hopes to help engineers:
• design safer and longer lasting wind turbines, and
• make better decisions in industries that operate in tough, corrosive environments—like offshore energy and marine engineering.
