The objective of the event is to provide a forum for informal discussions among experts in the field and to disseminate latest results. Younger workers and Ph.D. students are especially encouraged to participate.

The basic concept of keeping all participants in one conference venue combining conference facilities and accommodation allows maximum interaction between participants. NuTTS has maintained an informal workshop character.

NuTTS attends to the following topics for marine structures (ships, propellers, offshore platforms, etc.)

- Nonlinear flows around marine structures (LES, RANSE, Euler with or w/o free surface)
- Free-surface flows around marine structures (3-D ship seakeeping, free-surface viscous flows)
- Fluid-Structure-Interaction
- Related topics (validation experiments, numerical techniques, grid generation, etc)
