Using this technique, wind turbines are assembled and pre‐commissioned in nearby place and after that a complete and integrated turbine which includes a rotor, tower and foundation is installed in a single offshore operation (IRENA 2016). Thus, using this technique most of the offshore installation operations can be put to an end. With the help of customized vessels or tugboats, the combined turbine foundation is taken to the wind farm site. Use of this technology in the floating foundation technique will further make the usage of the latter more promising. As far as fixed foundations are concerned, use of gravity‐based foundations that can be floated out and sunk at the site is more useful. Installation cost as well as the exposure to health and safety risks decreases by these innovative techniques. Projected commercialization of this technique is by 2025 with more advances in technology to fulfil the requirement of large turbines.
