FORCE Technology hosted the 27th ITTC (International Towing Tank Conference) on 31 August – 5 September this year. The conference is held every three years and primarily contains presentations of the work carried out by the technical committees and decisions about the future work. The program of the evening will contain a summary of one of the activities of ITTC namely development of a new sea trial and tank test procedure which shall be used in the EEDI (Energy Efficiency Design Index) verification procedure valid for all new ships built after 1. January 2013.

The presentations of the evening will be in English

16:30 - 16:45 Introduction to the themes of the evening and general introduction to ITTC
by Aage Damsgaard, secretary of ITTC

16:45 - 17:30 (Including 15 minutes for questions and discussion). Analysis of towing tank tests and trial trip results with a view to determination of EEDI for new ships
by Anton Minchev, senior project manager, FORCE Technology
New ISO standard for analysis of towing tank tests and trial trips results with the view of e.g. determination of reference speed and correction or current.

17:30 - 18:00 EEDI: a verifier's perspective
by John Richards, Senior Ship Propulsion Specialist.
ABS Operational and Environmental Performance, Hamburg

EEDI verification is a formal requirement from IMO. Procedures have been developed by IACS to ensure compliance with the IMO regulations. This presentation will provide an overview of the procedures to be followed by classification societies with focus on: qualification of model basins, model test witnessing, sea trial witnessing and calculation of EEDI. Attention will be paid to relevant ITTC procedures and to the ongoing review process of the ISO 15016:2002 procedures dealing with the conduct and analysis of sea trials.

18:00 - 18:30 Refreshment

18:30 – 19:00 Towing tank’s view on EEDI verification
by Professor Gerhard Strasser, Vienna Model Basin
Concern has been raised over the consistency among towing tanks of the determination of Vref in the EEDI formula. This determination is based on both tank tests and sea trial analyses. Proffessor Strasser will address this and will give a fresh report on the deliberations at the MEPC 67 meeting, which takes place the week before the ITTC meeting in Danish Society for Naval Architecture and Marine Engineering (DSNAME)

19:00 – 19:15 Discussion and round-off
by Aage Damsgaard
