The paper presents the design and construction process of a series of four multipurpose ships for SME shipyard with some restrictions in production facilities. This process is based on software that is available free or the some tasks could be subcontracted by SME. The main dimensions are optimized by the system “Expert” and hull forms are generated by PolyCAD. Due to the restriction in the production facilities the ships are with the same breadth and for additional unification the depth is also equal. Three different hull structure topologies are evaluated by MARS2000 software and modeled by AVEVA Marine design software. The analysis includes evaluation of manhours for construction of parallel mid-body of the all variants. The analysis takes into account the restricted preassembly space and human recourse, lifting capacity of building crane, geometry of building slipway etc. Some conclusions for labor intensity and inf luence of series function are made based on the presented data.

In this work it is assumed that the results of the conceptual design are presented in the form of extended structural scheme. The structural scheme allows to be supplemented with information that specifies the important decisions which secure the expected functionality of the product. There is a propounded approach to integrate structural scheme, loaded with additional design information, into CAD model. This approach allows to automatically generate CAD models of parts that include skeleton models and mechanical interfaces as well as CAD model of assembly in finished state. This way more realistic CAD models containing the actual geometric relationships between the components would be created. On the other hand, the decisions taken at the conceptual design stage are automatically transferred to the CAD model, which reduces the treadmill work associated with its creation.
