INTACT SHIP SURVIVABILITY IN EXTREME WAVES: NEW CRITERIA FROM A RESEARCH AN NAVY PERSPECTIVE

This paper describes a joint navy research project on dynamic stability of intact ships. The main objective is the development of stability criteria that reflect the dynamic influence of waves on the safety against capsizing of intact frigates. A sound understanding of the physics involved and a practical ship motion simulation tool are essential elements in the approach taken. The first part of the paper provides an overview of the project approach and results, comprising a framework for developing dynamic stability criteria, physical aspects of waves and capsizing, and practical design and operational guidelines for frigates. The new guidelines applying particular to astern sea conditions, which are typically not covered by existing criteria; this can have an important bearing on modern hull forms. From a navy perspective, the following issues related to dynamic stability are addressed in the second part of the paper: 1) implementation of operational guidelines aboard navy ships, 2) the role of probabilistic methods related to capsizing of intact ships, and 3) evaluation of new design concepts in operational and extreme conditions.
