Piping layout integrated in ship design and stability evaluation

Damage stability assessment in ship design is a well-established area of our trade. However, where originally only a limited number of aspects were involved, gradually more details are included. Notably compartment connections by pipes and ducts etcetera. Combined with a high number of damage cases, in practice this results in a set of computations which is not complex as such, yet complicated by its sheer size. Although in the PIAS ship design software suite quite some dedicated tools are available, those have never been designed to support the requirements from today. In this light the software has been extended with a new system to fully define shape and topology of compartments and their connections. This paper reports on the system design, its application in damage scenarios, and on complications.
