24AVEVA World Magazine 2011|Issue 2First implementation of AVEVA PDMS in SwedenAt SIT's head office we met Björn Malm, Manager, Layout Department, Håkan Arvidsson, PDMS Administrator, Layout Department, and Olof Ekelund, PLR System, CAD IT Department. They explained that PDMS has been in use at Finspång since the late 1980s and that it was, in fact, the first implementation of PDMS in Sweden. They told us, 'We recognise AVEVA as a solid company which, for many years, has delivered reliable engineering tools which directly support our engineering disciplines. AVEVA has also provided very good product support and service, helping us to integrate and optimise our environment.'SIT now uses PDMS for the detail engineering of combined heat and power (CHP) plants and all associated and ancillary systems to the gas and steam turbines. Fabrication of the plant is often managed by a local contractor. Besides the fabrication information, SIT also delivers the 3D PDMS model of the plant to the fabrication site. More than 65 engineers at their office are experienced users of PDMS, which is currently being used for one cogeneration plant project in Bulgaria, one in Nigeria, and three in Belarus. 10-15 projects are in progress with PDMS for steam turbine plants, and about 40 for gas turbine plants.Turnkey plantsOne example of a turnkey CHP plant designed using PDMS is the Rya CHP plant for Göteborg Energi in Gothenburg, Sweden, which now produces around 30% of the city's electric power and district heating. At this plant, three 45 MW industrial gas turbines are each connected to a supplementary-fired heat recovery steam generator (HRSG). These three boilers feed a 137 MW steam turbine, and two district heating condensers, connected after the steam turbine exhaust, supply hot water to the city's district heating system.SIT designed and delivered the whole plant, including manufacturing the turbines in SIT's workshops in Finspång.SI TSiemens Industrial Turbomachinery AB (SIT) designs and delivers power units ranging from individual steam and gas turbines up to and including complete turnkey power plants for the production of electricity, steam and heat. SIT specialises in industrial-sized units, typically powered by steam turbines from 60-250 MW, and gas turbines from 15-50 MW.SIT is a long-established AVEVA PDMS and AVEVA Global user. When we visited them, they had recently extended their use of AVEVA Plant products by implementing AVEVA Schematic 3D Integrator and AVEVA Schematic Model Manager. They did this so that they could integrate their existing Comos P&ID with the PDMS 3D model, to further enhance their engineering performance.SIT, with more than 2,600 employees, is head-quartered in Finspång, Sweden, which is often described as the cradle of Swedish industry. There were ironworks there as early as 1496, and the manufacture of cannon started in the 1600s. During the 1700s and 1800s, Finspång became one of the biggest cannon makers in the world. A steam turbine company was established there in 1913, and it was this company which, in 2003, became Siemens Industrial Turbomachinery AB. SIT is now part of the Siemens Energy Oil & Gas segment, which also uses PDMS at multiple locations in Germany and in the Czech Republic.Siemens Energy is a leading supplier of a wide range of products, solutions and services for power generation, transmission and distribution worldwide.From left, Olof Ekelund, Björn Malm and Håkan Arvidsson.Magnus Feldt Industry Marketing Manager, AVEVAexpands use of plant design technology

AVEVA World Magazine 2011|Issue 225SIT is expandingWorld population is growing, and more people are moving to the cities. This results in increasing energy use and an unprecedented growth in the global demand for energy. Thanks to a very high level of activity and several new projects, SIT continues to expand and will be hiring a significant number of new staff over the next three years.Increased use of AVEVA GlobalWhen subcontractors are engaged in a project, AVEVA Global, a solution for multi-site concurrent working, has enabled SIT's engineers to successfully share the 3D model and the design information with the engineers at the subcontractors' sites. SIT expects the use of AVEVA Global to increase for future projects involving more subcontractors.Big savings expected from PDMS 12 and the AVEVA Mechanical Equipment InterfaceThe detailed designs of the specialist equipment used in a power plant, (e.g. the turbines), are typically carried out using a mechanical CAD system. However, 3D representations of this equipment, including the spatial geometry and connection points, also need to be available in PDMS for the teams carrying out the layout and detail design of the plant. In the past, re-creating these equipment designs inside PDMS has involved a lot of extra work. The new AVEVA Mechanical Equipment Interface will allow these Mechanical CAD models to be directly imported, and SIT will soon be upgrading to PDMS 12 to allow them to make use of the new interface.AVEVA technology integrates Comos P&ID and PDMSSIT's recent implementation of AVEVA Schematic 3D Integrator and AVEVA Schematic Model Manager means that they can integrate Comos P&ID with the PDMS 3D model. After a lengthy evaluation process, SIT selected the AVEVA solution as the best technical offering available for their work process. They were particularly impressed with the topology and connectivity checking available with this solution.Björn Malm, Håkan Arvidsson and Olof Ekelun told us, 'To be able to check the sequence, connectivity, tag and attribute data between the P&ID and the 3D model will raise the quality of the design at all stages of our projects. This will lead to fewer design iterations and fewer late changes, reducing rework and cost, and shortening schedules.'The complete solution is now fully configured and ready for first production use on a new cogeneration plant project starting in September 2011.AVEVA PDMS model of the Rya CHP plant.
