Informaatio- ja luonnontieteiden tiedekunta | Bachelor's thesis(2008) Turunen, Tuomas Arvo Ilmari - Kolmiulotteisten mallien hyödyntäminen voimalaitoksen käytössä ja kunnossapidossa
School of Science | Master's thesis(2012) Turunen, Tuomas Arvo IlmariA power plant consists of thousands of components whose location and related documentation is almost impossible to solve without a good knowledge of the plant. A 3D-navigation system represents a power plant by its 3D-model that can have its components linked to other information systems. By this way, besides a component's location, all of its documentation is available while examining the component in its environment. The graphical interface of a navigation system is based on a plant's 3D-model which must, at minimum, have its components identifiable. If no 3D-model of a plant exists, laser scanning and existing drawings can help the modelling work. Because plants keep changing even after their construction, models have to be stored in a maintainable format. In this master's thesis an own navigation system based on Bentley Navigator was built. An extension to Navigator that allowed linking a document management and an asset management system to plant's components, was written using Bentley's C/C~H-application programming interface. Fortum's power plant in Suomenoja was used as a pilot environment where Bentley's ProjectWise stored the i-modelformat 3D-model and other technical documentation while maintenance data was managed by IBM's Maximo. In Suomenoja's pilot test the navigation system's features where considered practical particularly the component searching from a 3D-model. A 3D-model was seen useful also in work planning because it shows the altitude differences of pipes and items underneath insulations. Thus measuring and dismounting at the plant area can be avoided. The comprehensive modelling of the plant and the updating of the P & ID diagrams was seen as the only significant issue. On the other hand, in addition to navigation, a 3D-model would be useful for example in design of new plant systems.
