Hamburg November 2nd 2006, at the Madison Hotel was held the seminar "Torsional Vibration and Shaft Alignment Technical Forum". The organizers of the conference were Mr. Alex Aarvik and Mr. Jo Øvstaas from DNV Software and Geir Dahler and Bjørn Johan Vartdal from DNV Maritime.

The first part of the agenda consisted of a presentation of the new Windows based Nauticus Torsional Vibration tool, which includes capabilities for direct coupled systems, geared/ branched systems and generator sets. A full demonstration of the software tool using typical marine propulsion systems such as electric- and diesel powered propulsion systems as well as geared propulsion systems was given by Jo Øvstaas from DNV Software.

This was followed by Geir Dahler, DNV Maritime, presenting different topics realated to torsional vibrations. First various damage cases which DNV has been involved in lately were discussed, and second a presentation which focused on advanced shafting design, and based on a paper published earlier this year at SNAME (Society of Naval Architects and Marine Engineers), was highlighted.

The last part of the seminar had focus on shaft alignment in the maritime industry. The topic was especially important due to the high number of alignment related damages occurring. Bjørn Johan Vartdal from DNV Maritime demonstrated how it is possible to solve complicated issues with knowledge and a good software tool. He also spoke about DNV’s considerable research on the effect of flexible hulls and propeller loads in order to bridge the gap between shaft alignment theory and reality.
