The article presents the TRIPOD method as one of the possible methods used for the analysis of stability accidents of seagoing vessels. The method allows for the identification of hazards and stability accident scenarios. A scenario here is a sequence of events leading to a given accident. Identifying possible stability hazards for a given type of vessel and possible scenarios of potential accidents is the first task of risk analysis in relation to ship stability. The article describes the stability loss accident of the ferry Jan Heweliusz in the port of Ystad. The course of the accident is described by citing the basic events leading to it. A scenario diagram consisting of blocks characteristic of the TRIPOD method and a specification of so-called barriers are also presented.INTRODUCTION 2
Current regulations regarding stability requirements for seagoing vessels are collected in the so-called International Code on Intact Stability (2008 IS Code).
The Code consists of two parts: Part A containing requirements that (since July 2010) have the status of mandatory requirements, and Part B containing recommendations. The stability assessment criteria contained in Part A of the Code were developed over 40 years ago and have been the subject of criticism for many years.
Their primary drawback is that they are prescriptive in nature and do not take into account the complex hydromechanical phenomena accompanying ship rolling in rough seas. From the point of view of ship safety, this is therefore not a satisfactory solution. Since the time of (…)
