Meeting 1 Washington D.C., USA
October 2004
Kick Off Meeting Coupled turbine/substructure dynamic modeling - A Kick-off meeting was held. Representatives from Denmark, Japan, Norway, the United Kingdom, and the United States attended. The October meeting attracted 32 participants from 8 countries. To maximize the benefit to the research community and to take advantage of experience with current turbine modeling effort in shallow water, it was decided to include both shallow and deep-water modeling.
