Three-dimensional modelling software tools enable the creation of a digital replica product—“Digital Twin”—a representative “Virtual Reality” as one prominent trends Industry 4.0. The development Digital Twin can start simultaneously with product, primarily for purpose selecting optimal technical and technological solutions prior to during physical construction, and, ultimately, intention manag...

Original scientific paper Since an evident tendency of the shipbuilding is that the sizes of ships are larger and larger, the dynamic interactions between the propulsion system and ship hull in large scale ships are much severer than those of the small sized ships. Ship hull deformations caused by the action of heavy excited wave forces could affect the vibration characteristics of the propulsi...

BACKGROUND Shipbuilding involves intensive welding activities, and welders are exposed to a variety of metal fumes, including manganese, that may be associated with neurological impairments. This study aimed to characterize total and size-fractionated manganese exposure resulting from welding operations in shipbuilding work areas. METHODS In this study, we characterized manganese-containing p...

During the XVI and XVII centuries the India Route was the longest regular commercial route of its time and connected Lisbon, Portugal, with Goa or Cochin in the Indian subcontinent. However, there is presently very little technical knowledge about the technical characteristics of the different ship types employed in this trade. This paper starts by describing briefly the shipbuilding treatises,...

Within a shipyard, many designers each having their own design objective cooperate in a complex design situation where a variety of software tools run on different hardware platforms. The exchange of design data models among these heterogeneous CAD systems is a difficult task because the systems involved have different data structures optimized for their own functions. CAD geometric models are ...
