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.

26AVEVA World Magazine 2011|Issue 2A very wise commentator once wrote that the biggest revenue loss in all plants around the world is human error. This, he said, was not because operators or maintainers make mistakes, but, instead, because they do not have the information to hand to make the right decisions.Such absence of information presents a huge problem in process plant environments. The whole plant lifecycle, from design, to brownfield activity, to shutdown, turns on the availability, exchange and update of all kinds of data and information. Yet many brownfield plants, particularly older ones, are still using non-integrated forms of information. These may be electronic, or simply paper. The barriers to 'converting' to an integrated, digital data set, where the right information is always available in electronic form, are high. The process is slow and costly.Examining the risksYet if you don't have this fully 'digital plant', the accessibility of all your data - 2D and 3D, documents, enterprise, and many more - suffers immensely. In any brownfield environment, there is significant divergence between the as-designed and the as-built plant. If this divergence is tracked, recorded and understood, it presents no danger, but if it is allowed to continue undetected and unexplored, it generates great potential risk. Operational costs increase as operators battle with inaccurate, out of date, or simply unavailable data and records. There is also an increased probability of an incident that could lead to excursions outside of the plant's operational perimeter, and create the potential for injury and fatalities, to both operator and the public. Regrettably, history has given us some powerful examples of this. In one facility, failure to capture and model a one-inch pipe run, and understand the dependencies on it, ultimately led to an incident that resulted in eight days' loss of operations, worth approximately $50m.The reality is that the teams involved in this incident probably did have access to at least some of the information in digital, rather than paper, form. But the real problem was the absence of any integrated digital data structure that could tie all this information together, across the many different applications and databases in which it was stored, and across all the different teams for which it had relevance. In the digital plant, integration is a must-have.
