Cover Story: As foundations represent approximately 35% of the total cost of an offshore wind project, it is essential that they receive special attention. There are different types of foundations, being the most common ones: steel monopiles, gravity-based structures (GBS), tripods, and jackets. Although GBS has not been widely used until now, there is research that has highlighted its advantages over other types of foundation. The offshore wind industry is trying to introduce improvements so as to turn GBS into a competitive foundation alternative, suitable for the widest ranges of water depth. The present article deals with GBS foundations. It begins with the current state of the field; it presents a classification of GBS foundations, as well as some reflections on future GBS alternatives.
