Abstract

Current naval ship design programmes are considered to be inadequately served by the preliminary ship design methodologies used to develop initial design features. This is due to a reliance on numerical design approaches that do not fully reflect the complex nature of the naval ship design problem. A new ''Building Block" design methodology is demonstrated. This methodology uses design descriptions integrating functional, and architectural issues with numerical design descriptions as functional Building Blocks. The Building Block methodology allows designers to undertake decision making during preliminary design with knowledge of all important design issues. The thesis scope includes all commonly encountered naval surface ship requirements for monohulls and also for unconventional hullform types, such as Trimaran. Justification for a new design methodology is presented in Part one of the thesis. General engineering design and specific naval design issues are detailed, leading to a discussion of current design methodologies. Comparison of alternative ship design methodologies highlights the need for an integrated approach based on architecture. The requirement for an architecturally centred design methodology leads to the Building Block design methodology, detailed in Part two. Major surface ship methodology issues are detailed. The concept of the design generator is developed as being that requirement which defines the section of the overall ship design space in which a final design will reside. The discussion considers the application of the new methodology to monohull ships, focusing on an Escort Frigate requirement. The methodology is also applied to amphibious landing ships and small naval vessels, demonstrating the effects of size and operational requirements on applicability. The discussion also demonstrates the application to unconventional craft by development of Trimaran and SWATH designs, noting that the more complex unconventional design problems encountered, benefited from the Building Block methodologies' strengths.
