On behalf of the Local Organizing Committee of the 7-th International Ship Stability Workshop. I warmly welcome all the participants of the workshop to Shanghai. Ship has been a powerful tool for marine transportation in the human history. With the global development of economics, the amount of marine transportation around the world is even increasing now. Among the various technical aspects in naval architecture, from an academic viewpoint, ship stability possesses its own unique and essential importance. I hope the present Workshop will provide a forum for a clear overview and deep discussions on the recent research progress in tins aspect. I appreciate very much all the kind support and help from the members of Standing Committee of the International Ship Stability Conference and the workshop session organizers. The Workshop would not be so successful without their enthusiasm and continuous efforts. Thanks also to all the authors for their contributions to the Workshop. Shanghai is one of the most advanced cities in China and great development has been achieved in past decade. I hope everybody will enjoy your stay in Shanghai.
