Requirement Analysis on Lightweight CAD Models in Ship PLM Environment and Its Application Examples

Abstract: Introduction of PLM in domestic shipyards is being retarded as ship PLM has yet to firm up return of investment and process integration. To implement a ship PLM system, it is required to share ship CAD model data in various design and manufacturing environments. Lightweight CAD models provide a promising solution for sharing CAD models in the product life cycle, which can expedite implementation of ship PLM in domestic shipyards in the near future. Compared to proprietary CAD models, it is easy for lightweight… Show more

“…Crane accidents are caused mainly by inferences and collisions that occur frequently due to the complexity of the work site, including the target block, equipment, and previously erected blocks when block erection operation or block turnover operation is performed using a crane in the shipbuilding process (Cha et al, 2009). Human accidents or problematic situations can occur if an inspection of the block erection process is not performed correctly in advance, which may lead to the necessity of cutting the interference member while the crane is holding a block (Cheon et al, 2013). The shipbuilding industry and researchers have used various methods, such as limitations on multi-level subcontracting, installation of crane collision prevention sensors, strengthening equipment management and field management supervision, and simulations, to prevent such problems (Cha et al, 2012;Hwang, 2013;MOEL, 2018).…”
