Abstract
The potential for mass reduction of monopiles in offshore windfarms using current design practice is investigated. Optimisation by sensitivity analysis is carried out for the following important parameters: wall thickness distribution between tower and monopile, soil stiffness, damping ratio and layout of structural details. The obtainable weight savings on steel up to 10-20%, compared with current practice.
