An Integrated Dynamic Analysis Method for Simulating Installation of a Single Blade for Wind Turbines
Zhao, Yuna; Cheng, Zhengshun; Sandvik, Peter Christian; Gao, Zhen; Moan, Torgeir (Journal article; Peer reviewed, 2018)Installation of blades for wind turbines is challenging due to large lifting height and high precision. Assessment of blade dynamic responses during installation needs advanced simulation tools which are limited at present. ... -
Design, Modelling and Analysis of a Large Floating Dock for Spar Floating Wind Turbine Installation
Jiang, Zhiyu; Yttervik, Rune; Gao, Zhen; Sandvik, Peter Christian (Peer reviewed; Journal article, 2020)Installation of floating wind turbines at the offshore site is a challenging task. A significant part of the time efficiency and costs are related to the installation methods which are sensitive to weather conditions. This ... -
Dynamic response analysis of a catamaran installation vessel during the positioning of a wind turbine assembly onto a spar foundation
Jiang, Zhiyu; Li, Lin; Gao, Zhen; Halse, Karl Henning; Sandvik, Peter Christian (Journal article; Peer reviewed, 2018)Installation of floating wind turbines is a challenging task. The time and costs are closely related to the installation method chosen. This paper investigates the performance of an efficient installation concept – a ... -
Mating Control of a Wind Turbine Tower-Nacelle-Rotor Assembly for a Catamaran Installation Vessel
Jiang, Zhiyu; Ren, Zhengru; Gao, Zhen; Sandvik, Peter Christian; Halse, Karl Henning; Skjetne, Roger (Chapter, 2018)The assembly and installation costs of an offshore wind farm can approach 20% of the capital expenditures; therefore, time efficient installation methods are needed for installing offshore wind turbines. This study ... -
Numerical Modelling and Analysis of the Dynamic Motion Response of an Offshore Wind Turbine Blade during Installation by a Jack-Up Crane Vessel
Zhao, Yuna; Cheng, Zhengshun; Sandvik, Peter Christian; Gao, Zhen; Moan, Torgeir; van Buren, Eric (Journal article; Peer reviewed, 2018)Jack-up crane vessels are commonly used to install offshore wind turbine blades and other components. A jack-up crane vessel is subjected to wind and wave loads, which cause motion at crane tip. Excessive motion at crane ... -
Numerical Modelling and Dynamic Analysis of Offshore Wind Turbine Blade Installation
Zhao, Yuna (Doctoral theses at NTNU;2019:190, Doctoral thesis, 2019)Installing offshore wind turbine blades is very challenging and risky due to large lifting height and high required installation precision. Offshore single blade installation is frequently adopted because of small deck ... -
Numerical study on the feasibility of offshore single blade installation by floating crane vessels
Zhao, Yuna; Cheng, Zhengshun; Gao, Zhen; Sandvik, Peter Christian; Moan, Torgeir (Journal article; Peer reviewed, 2019)Compared with jack-up crane vessels that are now widely used in offshore wind turbine installation, floating crane vessels are more flexible with respect to working water depth and are much faster in relocation. They are ...
