The index-based inherent safety assessment method is preferable in comparing alternative chemical process routes due to its ability to be used in the early process design stage with limited details availability of the route assessed. However, the current index-based inherent safety assessment methods available have the shortcoming of subjective scaling. The Numerical Descriptive Inherent Safety Technique (NuDIST) is an inherent safety assessment method for the research and development design stage that overcomes the shortcoming of subjective scaling by incorporating logistic functions in its scoring assignment. The aim of this paper is to verify the NuDIST method in comparison with the Prototype Index for Inherent Safety (PIIS) and Inherent Safety Index (ISI) in terms of subjective scaling elimination. The inter-boundary case subjective scaling is considered solved if the scores difference between sub-edge boundaries is small while the intra-boundary case subjective scaling is considered solved if every value in a range has different scores.  The results of the subjective scaling elimination test agree that NuDIST eliminates the shortcomings of subjective scaling with positive results for both inter-boundary and intra-boundary.

The author proposed the Vortex-induced Motion (VIM) simulation method of a semi-submersible type offshore floating structure using the wake oscillator model based on the potential theory and model test data. This method is easy to use for the time-domain simulation of the VIM amplitude, that is in-line, transverse and yaw motions, of the semi-submersible floater in case of being demented mooring safety assessment of that. The simulation method presented in this paper was modified the single circular floater simulation method with the wake oscillator model for a semi-submersible floater. Some empirical parameters, obtained from the systematic model tests used many semi-submersible floaters, are only decided from external form of the semi-submersible floaters, that is the column / lower hull ratio etc. This simulation method is able to indicate general VIM trend and to be used for the assessment of mooring lines safety in the design stage. Using the VIM amplitude simulation, fatigue damage of mooring lines on one sample semi-submersible floater was investigated as an example.
