Abstract. The global floating offshore wind energy industry is rapidly maturing with several technologies having been installed at pilot and demonstration scales. As the industry progresses to full array-scale deployments, the optimization of marine activities related to installation, operation \& maintenance and decommissioning presents a significant opportunity for cost reduction. This paper reviews the various marine operations challenges towards the commercialisation of floating wind in the context of spar-type, semi-submersible and Tension Leg Platform (TLP) technologies. Knowledge gaps and research trends are identified along with a review of innovations at various stages of development which are intended to widen weather windows, reduce installation costs and improve the health and safety of floating wind related marine operations.

Short summary
Marine operations represent a significant proportion of costs involved in the installation, operation, maintenance and decommissioning phases of a floating wind farm. The floating wind industry is reaching array-scale deployments and it is very important to optimize the various marine operations involved in each of these phases. This paper analyses the various challenges in the path and opportunities for encountering them by the transfer of technical know-how from similar offshore sectors.
