碩士 / 國立高雄海洋科技大學 / 輪機工程研究所 / 96 / A pipe route design automation method, called Pipe Trunk Based Pipe Routing Design Method (PTR Method), has been developed to allow new pipes to pass through pipe trunks and connect a pair of source and destination points specified by engineers in the engine room piping system design processes of a ship.
In the PTR Method, a pipe trunk is defined by a line segment with high-bound and low-bound width limits. A spatial, breadth-first search method has been developed to search the pipe trunk paths connecting a pair of source and destination pipe trunks. Pipe sliders are used to book-keeping the existing and new pipes in pipe trunks. Edge-Operators have been developed to determine the geometry of the pipes connecting pipe trunks following shipyard’s pipe design standards. The PDMS input files of the new pipe routes can be generated automatically, and the CAD solid models of the new pipe routes can be added to the engine room model for engineers to select preferred routes.
The application of the PTR Method is for most engine room spaces except the main floor where most pipes are not in pipe trunks. The advantages of using PTR Method include (1) forcing the engine room pipes to be arranged in predefined pipe trunks, (2) generating the CAD solid models of the pipes automatically, (3) reducing the chance to have pipes interfere with other entities, and (4) pipe routes searched are independent of the arrangement of manufacturing blocks of the ship.
