Offshore Modeling Needs Workshop

International Energy Agency Task 23
Offshore Wind Energy Technology and Deployment

Subtask 2 - Technical Research for Deeper Water
January 13–14, 2005
Risø, Danish National Laboratory
Roskilde, Denmark

The kick-off meeting for IEA Task 23 on Offshore Wind Energy Technology and Development subtask 2 – Technical Research for Deeper Water the committee discussed the need for offshore model improvements for all water depths. The committee decided to initiate a task to define coupled turbine/substructure dynamic modelling needs and a plan for collaboration on this effort.

Some of the topics discussed were:
1) Define the capabilities and limitations of current offshore modelling state of the art. This would include the wind turbine and oil & gas industry.
2) Define and plan a coupled code verification exercise and code to code comparison.
3) Assess the requirements for test data to validate codes.
4) Assess the impact/sensitivity of wave loading on deep water platforms.
5) Consider extreme breaking waves, ice loading, and wave grouping in deep water.
6) Define hybrid model testing and validation effort.
