Operational Limitations of River-Sea Ships in the Framework of the Second Generation Intact Stability Criteria

Abstract

The paper examines the possibilities for using the Second Generation Intact Stability Criteria (SGISC) framework in stability assessment and calculation of operational limitations of the river-sea ships. The level 2 vulnerability assessment procedures for dead ship condition and excessive accelerations are used to derive the operational limitations of a typical European inland container vessel in the North Sea coastal zone. The results are in good agreement with the operational experience in the designated area, but provide additional insights into safety of river-sea ships that could not have been observed by the classic stability analysis. It is shown that the approach used by the SGISC could be successfully applied to river-sea ships, provided that appropriate modifications of the Criteria are introduced.
