L03 - OC4 Jacket |
|
OC4 (Offshore Code Comparison Collaboration Continuation) is a code-to-code verification project operated under the IEA (International Energy Agency) Wind Task 30 and coordinated by NREL (National Renewable Energy Laboratory). In Phase I of OC4, participants used an assortment of simulation codes to perform a coupled simulation of a 5-MW wind turbine installed on a jacket support structure in 50 m of water. Code predictions were compared from load case simulations selected to test different model features. Although Flexcom was not officially represented in OC4, the software has been retrospectively benchmarked against OC4 results, as NREL and the IEA have kindly made all data from the project publicly available.
The Results section presents a brief summary of a code-to-code comparison of simulation models built using Flexcom and other software tools. Full details of the numerical models and the benchmarking exercise may be found in the technical paper (Connolly & O'Mahony, 2021). Consistent with the copyright agreement, the authors hereby acknowledge ISOPE as the original publisher and copyright holder.
The overall layout of this example is as follows:
•Introduction gives an overview of the OC4 jacket, the load cases simulated, and the project participants and software tools.
•Model Summary describes the Flexcom model in detail.
•Results from Flexcom are presented alongside results from the software tools used in OC4.
