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 ... -
Numerical study on deployment of subsea template using coupled and uncoupled model
Hauge, Nils Olav; Li, Lin (Peer reviewed; Journal article, 2021)This study compares deployment of a subsea template simulated as a coupled model and as an uncoupled model in the time domain simulation software Orcaflex. Defining vessel motion as prescribed simplifies the model and will ... -
Numerical study on splash zone crossing with subsea template and ROV
Hauge, Nils Olav (Master thesis, 2021)External loads on a free-floating vessel affect the vessel responses in waves. DNV’s recommended practice for modeling and analysis of marine operations [1] categorizes lifting of an object above 1-2% of the vessel ... -
Numerical study on structural responses of gravity-based fish cages
Sim, Jaesub (Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020)The location of a fish farm is moving towards more exposed locations due to spatial and environmental concerns. As the fish farm moves to open seas, the structure of the fish farm would undergo increased environmental loads ... -
Numerical study on the deployment of a subsea template
Amer, Adham (Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-06-30)Subsea templates are normally transported to the installation site on the deck of a crane vessel. After being lifted off from the deck, the template is 1) over-boarded from the initial location to the target position by the ... -
Optimization of Spar-Buoy Foundation for Offshore Wind Turbines Using Open-Source Programs
Vika, Torstein Bakkan (Master thesis, 2021)Low carbon and renewable energy are paramount to tackle climate change and supply the increasing energy demand in a sustainable way. In recent years, the offshore wind industry has attracted growing attention for its ... -
Statistical Modeling and Applications of Joint Distributions for Significant Wave Height, Spectral Peak Period, and Peak Direction of Propagation: A Case Study in the Norwegian Sea
Serta, Clarissa Pires Vieira; Haver, Sverre Kristian; Li, Lin (Peer reviewed; Journal article, 2023)The estimation of long-term extreme response is a crucial task in the design of marine structures. The target extreme responses are typically defined by annual exceedance probabilities of 10-2 and 10-4. Various approaches ... -
Typical hydrodynamic models for aquaculture nets: A comparative study under pure current conditions
Cheng, Hui; Li, Lin; Aarsæther, Karl Gunnar; Ong, Muk Chen (Peer reviewed; Journal article, 2020-03)The net is regarded as the most critical component in marine aquaculture facilities as it is the only barrier which protects the environment from fish escapes. Accurate predictions of the net cage deformation and drag force ...
