Numerous studies have determined that one of the major factors affecting global competitiveness in the marine industry is the ability of an organisation to incorporate past experience into future products. Several terms are used to refer to this practice, such as 'data reuse' or 'experienced ship design'. However, regardless of the terminology, the need to adapt past designs to new or changing market demands is paramount to winning new business in today's market and delivering quality products on time and within budget. Data reuse can take many shapes and forms beginning with basic capabilities in the areas of standardisation of individual piece parts, uniformity of parts within an assembly, or symmetrical design consistency about the vessel's centreline. More advanced 'design reuse' capabilities are possible by extending this concept from 'geometric' to 'topological' similarity where some aspect of the design basis is adaptively reapplied from one region of the vessel to another. The authors have been involved with the definition, development, and implementation of functionality in this area for more than three years. In this paper they will present an overview of the major functional areas that can benefit from this capability; compare and contrast the various technical solutions that have been implemented to address these requirements; and discuss in detail the power, flexibility, and potential of a highly advanced 'copy' functionality for similar structure. After briefly discussing the differences between data reuse and design reuse and the means of achieving data reuse and design reuse in the CAD-CAM area today, this paper reviews in detail the concept and implementation of similar copy in SmartMarine 3D. Finally some examples are briefly reviewed of the application of similar copy to design reuse in shipbuilding and offshore.
