Analysis of spar and semi-submersible floating wind concepts with respect to human exposure to motion during maintenance operations
Kaptan, Mert; Skaare, Bjørn; Jiang, Zhiyu; Ong, Muk Chen (Peer reviewed; Journal article, 2022)Floating offshore wind turbines (FOWTs) are expected to experience onsite maintenances and inspections during their lifetimes. To carry out offshore maintenance activities, a crew will be transferred to an FOWT and spend ... -
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, 2018-05-11)Installation of floating wind turbines is a challenging task.

Metocean conditions at two Norwegian sites for development of offshore wind farms
Cheynet, Etienne; Li, Lin; Jiang, Zhiyu (Peer reviewed; Journal article, 2024)This paper examines metocean data from NORA3, a state-of-the-art wind and wave hindcast dataset for Northern Europe. Two offshore Norwegian areas, Utsira Nord (UN) and Sørlige Nordsjø II (SN2), are investigated. Both areas ... -
Numerical analysis of a vessel-shaped offshore fish farm
Li, Lin; Jiang, Zhiyu; Høiland, Andreas Vangdal; Ong, Muk Chen (Peer reviewed; Journal article, 2018)The aquaculture industry is aiming to move fish farms from nearshore areas to open seas because of many attractive advantages in the open water. However, one major challenge is to design the structure to withstand the ... -
Numerical study of a concept for major repair and replacement of offshore wind turbine blades
Jiang, Zhiyu; Li, Lin; Guachamin-Acero, Wilson (Peer reviewed; Journal article, 2020-03)Repair and replacement of offshore wind turbine blades are necessary for current and future offshore wind turbines. To date, repair activities are often conducted using huge jack-up crane vessels and by applying a reverse ...
