Reducing Total Ownership Cost: Designing Inside-Out of the Hull

摘要

It cakes a lot of engineering to go successfully through the development process from a ship concept to the delivery of a "full-up" warship. The Navy has experimented with many ways to do this both effectively and efficiently. In terms of effectiveness (i.e., does the ship do what it is supposed to do?) the Navy has been reasonably successful. However, in terms of efficiency (i.e., are the ships efficient to produce and own?) there is much room for improvement. Being able to efficiently produce and own a warship must be addressed during the earliest stages of design. A number of improvements to early stage ship design capabilities are being developed in order to make the process more effective and efficient. This paper addresses the critical stage of the Design-Build-Own process of initially sizing the hull during concept design. The author proposes the methodology of "Designing Inside-Out of the Hull" combined with the development and use of more physics-based design tools during concept and preliminary design.
