IMO second generation intact stability criteria on PCTC’s

Abstract

This thesis studies the new second generation intact stability criteria, which is the upcoming criteria, through an example ship. Deltamarin Ltd wants to find out what it takes from the design process of the ship when these new criteria become mandatory. At this moment PCTC’s (pure car and truck carriers) are a big part of Deltamarin Ltd’s projects. For that reason Deltamarin Ltd wants to know, in which kind of way these new stability criteria will affect the design process of the ship. This thesis aims to illuminate the effect these new criteria will have on the stability calculation of the ship.

A stability calculation model from a basic design project have been created for this thesis. Loading conditions have been created in the model and based on those an analysis of the criteria and their effects on the design process have been made. In this thesis refinements of the new criteria have been made on top of the criteria currently in use. The criteria were calculated with eight loading conditions. Due to confidentiality not all loading conditions can be presented. The goal has been to examine whether or not this example project complies with these new criteria and apply the results to Deltamarin Ltd’s disposal.

The thesis concludes that only few criteria was not met. Judging by this conclusion Deltamarin Ltd is well prepared for future guideline changes and with some optimization to the design process, will achieve the requirements presented in the second generation intact stability criteria. Since the new criteria are additions to the current requlations, it is simple for Deltamarin Ltd to start using the new criteria.
