“…It uses ballast weights in the lower part of the structure, which creates a righting moment and high inertial resistance to pitch and roll [3]. Due to the large draft requirement the floater concept tends to be applied in waters deeper than 90m and can cause some challenges in the installation phase [35]. The The availability of metocean data has also been essential for the selection process.…”

“…The tower and associated costs have been adjusted to each of the FOWT designs.The semi-submersible floating substructure gains stability through distributed buoyancies and uses the weighted water plane area for the righting moment. This tends to lead to a larger surface structure, which involves the use of more material in comparison to other concepts[35]. The concept considered in this study is made of concrete and can be constructed locally worldwide[36].…”

In this paper, a sensitivity analysis is performed on the levelized cost of energy (LCOE) for floating offshore wind farms (FOWFs). The analysis is carried out for three floating wind turbine concepts and three different offshore sites. At first, a methodology is presented for calculating the LCOE for a specific FOWF. Afterwards, the base LCOE values for each of the floating wind turbine concepts and sites are obtained. The sensitivity analysis includes over 325 input parameters that are studied in order to identify the ones that most influence the LCOE. Furthermore, a complementary sensitivity analysis is performed by varying the input parameters based on uncertainty ranges provided by each of the concept designers. This serves to obtain maximum and minimum LCOE variation limits and possible cost reduction potentials. It has been observed that the capital cost related parameters such as turbine, substructure and mooring system manufacturing cost as well as power cable cost are some of the most influencing parameters besides common parameters such as the discount rate and energy losses. The LCOE variation limits obtained in this study vary between 67e/MWh and 135e/MWh among the different concepts and offshore sites including offshore transmission costs.

“…The main components are the dismantling costs of the wind turbine, floating platform, electric system, mooring and anchors. Some anchors, eg: drag-embedded anchors, are easily recoverable, which would save costs and time (González and Diaz-Casas (2016)). There is an additional cost due to the cleaning of the wind farm site which is of environmental concern (Castro-Santos et al (2016)).…”

“…By comparison, the floating wind turbine (FWT) is more mobile and flexible to deploy, easier to dismantle, and more suitable for relatively deeper waters. In addition, the deployment site of FWTs is far away from the coastline, eliminating the harm of noise and electromagnetic waves to the environment [5] . Also, compared to nearshore fixed turbines, a larger capacity of turbine like the 9.5 MW units in Kincardine UK can be installed onto floating structures to harness more power so as to achieve a higher levelized cost of energy (LCOE) [6] .…”

With the increasing demand of energy and the limitation of bottom-fixed wind turbines in moderate and deep waters, floating offshore wind turbines are doomed to be the right technical choice and they are bound to enter a new era of rapid development. The mooring system is a vital system of a floating wind turbine for station-keeping under harsh environmental conditions. In terms of existing floating wind turbine projects, this paper is devoted to discussing the current status of mooring systems and mooring equipment. This paper also presents the mooring analysis methods and points out the technical difficulties and challenges in mooring design, installation, operation and maintenance stages. Finally, the developing trends of the mooring system are summarized, aiming to provide a reference for future mooring research.
