Abstract

Ships and offshore structures are often built in short series or as individual made-to-order products. The high complexity of the products implies an intensive design and planning process, where many tasks have to be performed in parallel. Often, manufacture of one part of the product is going on at the same time as the detailed design of another. The design process is well supported by computerized tools. 'Design for production' is a well known concept and is often implemented. Computer support for part fabrication exist in most shipyards and is often one of the first applications that are implemented. However, shipbuilding is very much an assembly process where the production engineering is a key function. Computer support for production engineering is an important area for improvement to increase the output of a shipyard. The production engineering starts early with the definition of building strategy and continues with the definition of the assembly structure in parallel with the detailed design. When the production engineering definitions are combined with the information stored in the product model during design, the information needed for assembly parts lists, assembly drawings etc., can be derived from the product model instead of being created manually. 1 The shipbuilding process
