“…However, platform TLP with no tensioned mooring (slack or transitional) will be rejected, considering its own definition, which implies tension. Furthermore, drag embedment anchor does not allow vertical forces and plate anchor does not accept horizontal forces [19].…”

The aim of this article is defining a methodology which allows us to evaluate the main mooring and anchoring costs of floating offshore wind farms. In this sense, costs of most important phases of life cycle will be analysed: manufacturing, installation, exploitation and dismantling. For this purpose several models will be defined taking into account the type of floating offshore wind platform (semisubmersible, Tensioned Leg Platform or spar), mooring disposition (transitional no tensioned, slack no tensioned, tensioned with 90º or tensioned with 45º), mooring material (chain, cable and synthetic fibre) and type of anchor (drag embedment anchor, suction pile, gravity anchor and plate anchor). Finally the proposed method will be applied to know mooring costs of a substructure located in the region of Galicia (North-West of Spain). Results show how each of these costs depend on the model considered, which help investors to decide what the best model is.

Abstract. The main developments in offshore wind power are focused on wind turbines with foundations on seabed. However, there exist important limitations for installing these structures in places with high depth within short distance from the coast.This means that the progress of offshore wind energy around the world is tied to the development of safety and low cost floating platforms for renewable energy offshore devices [ 1 ].Therefore, the first aim of this paper is to know which alternatives exist for a floating offshore wind farm establishment and design parameters are independent or dependent of platform configuration. In order to evaluate each alternative, the request inversion for each configuration has been analyzed.From this point of view, the conclusion is that a string configuration for the electrical network is better than a star configuration. Moreover, an accommodation platform cannot be established due to the fact that it would increase the costs considerably. With regard to maintenance, it would be better to have a proper vessel only if the number of trips is more than three.
