Why are offshore turbines bigger than onshore ones? 🌊 It's not just about stronger winds. Planning, logistics and site constraints play just as big a role. On land, the limitations start before the turbine even arrives. Nacelles, blades and tower sections travel by road, so every bridge, tunnel, roundabout and overpass caps how large a single piece can be. Cranes and the ground itself add another constraint, as there's only so much weight they can lift and support. Building an offshore-scale turbine on land is often simply impossible. At sea, the constraints are different: ▪︎ Components are shipped directly from port by vessel, allowing for far larger parts. ▪︎ Stronger, steadier winds reward bigger rotors with higher yield. ▪︎ There are fewer height, noise and setback constraints, and more space to build at scale. Larger offshore turbines are not about size for its own sake. They are the result of different logistics, engineering limits and site conditions.
