Vortex Induced Motion (VIM) of a Deep Draft Semi® with four square columns has been observed in model tests and in the field for a prototype configuration. The model test observations were developed into design guidance procedures. Some of the assumptions based on the model test results are validated with the field observations. A quantitative description of the field measurements is presented. A comparison between the field observations and the design guidance is provided.
