DAVI Monopiles - Fixed-Bottom Foundations

Monopiles are foundation structures that typically have a diameter ranging from 7 to 15 metres (23’ to 50’); they are made of steel, using plate up to 4 or 4,5 metres (13’ or 15’) width and thicknesses varying between 50 and 170 millimetres (2" to 7"). Monopiles sections are cylindrical and conical in shape. Their maximum length can reach between 80 and 120 metres (262’ and 394’); they weigh between 3,000 and 4,000 tons. Monopiles are designed to be driven into the seabed and provide support for wind turbine towers. They are used in water depths ranging from 50 to 60 metres (164’ to 196’). The angle of conicity, which is the tapering of the conical part of the structure, varies between 10 and 16 degrees.
