10.7. Optimization considerations

The tower is a relatively low-technology component that can also be modularized depending on the application. Offshore tower and SbS make up a significant portion of the OWT's total installed cost; therefore they lend themselves to be one of the best candidates for component optimization. The taper of a typical offshore tower, for example, favors an optimal distribution of the wall thickness as the diameter increases, while still retaining a required stiffness level. On land, the maximum outer diameter (OD) at the base of the tower is constrained by transportation considerations. Offshore, stiffness and buckling strength requirements may demand even larger diameters than onshore, but the transportation constraints ...
