Design Workflow within AVEVA NET AVEVA Plant solutions support the entire plant lifecycle from design to procurement and construction: AVEVA PDMS enables 3D design collaboration across multiple disciplines; AVEVA VPE manages P& ID diagram data and process equipment; AVEVA VPRM manages project resources and materials; and AVEVA NET provides a comprehensive platform for information management. AVEVA NET has the capability to manage 3D models, ISO drawings, P& ID diagrams, floor plans, and many other types of plant information and data. With the use of KKS coding, 3D models, ISO drawings and P& ID diagrams are connected, to facilitate the search and review of information. Such detailed information proves advantageous to Owner Operators after handover. During the design stage, PDMS models are regularly updated into AVEVA NET. ISO and P& ID diagrams are also imported into AVEVA NET with data import tools. There are many review stages throughout the plant design process, from initial setup to initial design, accreditation by professional bodies, composite review, command map, command map professional review, command map composite plan review, construction drawing design review, and beyond. There are also many parts to each stage. For example, in the piping design stage, the equipment model must be drawn according to the information provided by the supplier, followed by the modelling of piping layout, stress calculations, and so on. With so many processes involved, it is necessary to introduce design workflows that segregate the various parts of the design stage, in order to better utilise, and benefit from, the application of AVEVA NET. AVEVA NET can then support the design workflows which need information contained within the 3D models imported from AVEVA PDMS. A basic workflow within AVEVA NET, showing a linear process.

AVEVA NET - wherever you are in the lifecycle Construction businesses and Owner Operators alike benefit from AVEVA NET's ability to help manage quality, validation, risk, time and cost. AVEVA NET delivers proven gains in: . integrated project management . handover and commissioning . operational readiness . operations maintenance and reliability . plant engineering . health, safety and environmental compliance. AVEVA NET is about supporting excellence in information management at any point in the lifecycle - not just in the design and construction phases. Page 22| AVEVA PIPELINE | 2010 Issue 2

Multi- disciplinary collaborative design At the AVEVA Symposium of Integrated Plant Engineering System in 2009, Shanxi Electric Power Exploration & Design Institute gave a presentation on multi- disciplinary collaborative design. Case studies on two projects were presented: a 2 × 600MW plant project in Huozhou, and a 2 x 300MW plant project in Linfen. Shanxi selected AVEVA PDMS in 2000 for a host of reasons: it provided comprehensive database support, sound engineering data management, a unified design workflow control, and professional support from AVEVA. The application also facilitated the exchange and management of information, presenting a platform where designers and personnel could to work together even though they were separated physically, and by departments and disciplines. The collaboration that took place across the various disciplines involved those in the boiler, hydraulics, electrical, thermal, coal, HVAC, chemical, ash removal and other divisions. Through this collaboration and the use of AVEVA PDMS, the benefits Shanxi reported were: . 20- 30% reduction in design time . zero clashes . 10- 30% reduction in time for design modification . improvement in project productivity and material utilisation . reduction in material wastage through improved design . tool for project management support . easy access to operation and maintenance data. Using AVEVA PDMS within the two projects, complete and accurate digital information models of the projects were obtained. These asset- oriented and integrated models will benefit Shanxi, as they contain a collection of historical data and documents to support and manage the full lifecycle of the plants. AVEVA NET in modelling The company received an EPC contract for 2 × 330MW flue gas desulphurisation engineering projects at the Liupanshan power plant. Using AVEVA NET, simulation of the construction could be demonstrated, as well as simulation of the maintenance process. The operation carried out in AVEVA Review could be replicated in AVEVA NET. The following figures indicate the plant tour at two different time points. 3D Model within AVEVA NET - the level of detail is well suited to users' needs.

It can also be used in modelling, to simulate maintenance works, which is particularly useful for Owner Operators, enabling new employees to understand the construction and operations processes of the plants. Furthermore, AVEVA NET is open- sourced, enabling customisation to fit the needs of the organisation. AVEVA PIPELINE | 2010 Issue 2 | Page 23
