Newest NGO at IMO, ITTC supports DE in revising the HSC Code

ITTC’s assistance had been requested by IMO for the revision of the High-Speed Craft Code, in particular the Interim Guidelines for the conduct of high-speed craft model tests. The model test guidelines have been reviewed by ITTC’s Stability in Waves Specialist Committee; a proposal with revised guidelines by ITTC was submitted to DE49 (paper DE 49/5/2). ITTC was officially granted the NGO status by IMO in November 2005. The proposed model test guidelines and their inclusion in the amended 2000 HSC Code were accepted by the Sub-Committee at DE49 with due gratitude to ITTC. This was a typical area in which ITTC can provide unique expertise to IMO, and it is anticipated that ITTC will be able to provide more constructive support in the future in its capacity as NGO.
