Scope of the Project: KEPCO Engineering & Construction Company has designed Samcheok Unit 1 and 2 in South Korea, the world’s first 1,000MW Coal Fired Power Plant which has a configuration of combination of two 500MW circulating fluidized bed boilers and one 1,000MW turbine using ultra-supercritical steam condition for the first time in the world.

Considering mountainous and abruptly changing environment of the east coast in Korea, KEPCO E&C arrange plant equipment in a terraced disposition to promote efficiency of the gas emission control system and reduce the amount of civil engineering aiming at building economic and eco-friendly power plants. In addition, indoor coal shed and low–rank coal adoption makes this plant environmentally friendly power plant.

Information Technology: The traditional way to create 3D piping design, integrating cold-state (installed) piping geometry only, results in not detecting clashes which could happen between adjacent components during normal operation. In this project, deflected piping by thermal expansion was generated from AutoPIPE. And it was integrated as well as cold-state (installed) piping and then reviewed in Navigator to detect clashes with adjacent 3D components such as steel structure, cable tray and other Plantspace piping. Consequently, pre-finding and resolving 10+ major clashes that could impact project construction schedule and costs gave project stakeholders great satisfaction.

Reduce time of project delivery: To get greatest design accuracy Microstation, Plantspace Design Series, Navigator and TDVS(Three Dimensional Design Verification System, In-house) were applied. Integrated 3D models were reviewed to detect and resolve clashes. Re-design rate by design error was reduced by 15% compared with precedent project. Drawing extraction was executed after design verification completes so it contributed to nature conservation trend by reducing paper consumption.
