ITTC has an important role as a cooperation platform for all towing tank organizations. It gives SSPA, as an active member, an opportunity to influence the worldwide shipping community. At the ITTC’s 28th full conference, the Seakeeping Committee presented a recommended procedure for determining fw, that is largely based on work by our experts. A new Specialist Committee on Combined CFD/EFD methods was decided. The chairman is one of SSPA’s experts.
