DigiHydro

Offentlig prosjektsammendrag

Our intention of the DigiHydro project is to connect two essential early design disciplines and by this help Naval Architects to save time and have better data consistency. The geometrical definition of hull shapes and the subdivision into tanks and compartments is a design process relevant for many design disciplines. Ship stability calculation is a required process for designing and building a vessel that is often performed with specific niche software packages such as NAPA. To perform ship stability calculation the same geometrical definition is required as in the design discipline. Today this is resulting in two geometrical definitions of the same shape: In the CAD software and the stability package. The user needs to define the same shape twice in the different software and [in event of change] ensure consistency between the two geometrical definitions. NAPA stability calculation is not supporting any of the industry default exchange formats for geometry such as STEP, JT, IGES, or similar in a way that tank definitions can be exchanged efficiently between state-of-the-art CAD systems [such as Siemens NX] and NAPA. With DigiHydro we started to build an interface for exchanging tank geometry from the native NX geometry definition into the native NAPA geometry definition. We also interface related metadata. We intend to ensure data consistency between all design disciplines by avoiding any manual assignment or creation of data more than once in the definition of the vessel's digital twin.
