Assessment of operational limits : Effects of uncertainties in sea state description
Li, Lin; Haver, Sverre Kristian; Berlin, Nikita (Peer reviewed; Journal article, 2021-02)For operations dominated by waves, operational limits are normally expressed in terms of allowable sea state parameters, such as the significant wave height (Hs) and spectral peak period (Tp). The allowable sea states need ... -
Comparative study of five commonly used gravity type fish cages under pure current conditions
Cheng, Hui; Li, Lin; Ong, Muk Chen (Peer reviewed; Journal article, 2022-04)Gravity type fish cages have been commonly used in marine aquaculture for years. However, only limited research efforts have been made to assess the influences of different design parameters on the structural responses of ... -
Development of a coupling algorithm for fluid-structure interaction analysis of submerged aquaculture nets
Cheng, Hui; Ong, Muk Chen; Li, Lin; Chen, Hao (Peer reviewed; Journal article, 2021-12)A coupling algorithm between two open-source numerical toolboxes, i.e., OpenFOAM and Code_Aster, is implemented for fluid-structure interaction analysis of submerged nets. This algorithm is developed to handle the wake ... -
Dynamic Analysis and Extreme Response Evaluation of Lifting Operation of the Offshore Wind Turbine Jacket Foundation Using a Floating Crane Vessel
Chen, Mingsheng; Yuan, Guibo; Li, Chun Bao; Zhang, Xianxiong; Li, Lin (Peer reviewed; Journal article, 2022)The jacket is the most widely-used fixed foundation for offshore wind turbines due to its superior strength and low installation cost in relatively deep waters. Floating crane vessels are commonly used to install jacket ... -
Dynamic Analysis of Splash-zone Crossing Operation for a Subsea Template
Amer, Adham M.; Li, Lin; Zhu, Xinying (Peer reviewed; Journal article, 2022)Subsea templates are steel structures used to support subsea well components. Normally, offshore crane vessels are employed to install them to the target location on the seabed. Crossing the splash-zone during the lowering ... -
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. The time and costs are closely related to the installation method chosen. This paper investigates the performance of an efficient installation concept – a ... -
Effects of mooring line breakage on dynamic responses of grid moored fish farms under pure current conditions
Cheng, Hui; Li, Lin; Ong, Muk Chen; Aarsæther, Karl Gunnar; Sim, Jaesub (Peer reviewed; Journal article, 2021)Due to the lack of sheltered area, Norwegian fish farms are expanding to more exposed and remote sites. The severe environmental conditions in exposed sites can increase the risk of structural failure during aquaculture ... -
Feasibility Study of a Novel Open Ocean Aquaculture Ship Integrating with a Wind Turbine and an Internal Turret Mooring System
Liu, Hanyu; Chen, Mingsheng; Han, Zhaolong; Zhou, Hao; Li, Lin (Peer reviewed; Journal article, 2022)Marine aquaculture has been expanded into more remote areas due to the increasing demand for high value-added fish products, bringing more challenges in fuel supply and mooring safety to open ocean aquaculture farms. ... -
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 modelling of hydrodynamic responses of Ocean Farm 1 in waves and current and validation against model test measurements
Jin, Jingzhe; Su, Biao; Dou, Rui; Luan, Chenyu; Li, Lin; Nygaard, Ivar; Fonseca, Nuno; Gao, Zhen (Peer reviewed; Journal article, 2021)With the continuous growing of the aquaculture industry and increasingly limited fish farming sites at close to shore areas both in Norway and worldwide, there is a need to develop fish farms suitable for aquaculture ... -
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 ... -
