(continued) Jim illustrated Atkins' experience with some interesting project case studies, citing the Abu Tubul gas processing plant in Oman as a turning point in the software the company used. The whole job was supposed to be executed in PDMS, but after the client fast-tracked the project, Atkins decided to extract the information from the 3D model to generate the drawings in AutoCAD, to produce the Bills of Materials and 2D drawings more quickly than using PDMS Draft. However, there was a caveat. 'The minute you break its link from a model, a drawing becomes useless,' Jim explained. 'The data can't be updated. The problem with the previous software was that as we updated the design drawings, it wasn't being reflected in the 3D model design. The model and the drawings continued to diverge as successive modifications compounded previous inconsistencies. It took a lot more effort to deliver a satisfactory result and we had to go back to basics to create robust Quality Assurance and Quality Control processes,' continued Jim. 'It meant rewriting many of our procedures around PDMS.' Apache Energy project Learning from the experiences of the Abu Tubul project, Atkins decided to put PDMS more at the centre of its engineering. The use of AutoCAD was abandoned and drawings were generated directly from PDMS instead. At around the same time, Atkins was awarded the Varanus Island Compression Project (VICP) for Apache Energy. It was a complex greenfield project, but with a lot of brownfield tie-ins and a demanding 14-week design schedule. This highly collaborative, 8,500-man-hour project involved all engineering disciplines, as well as the client, at each step of the design process. Modular design enabled Atkins to run multiple teams in tandem to fast-track the work. As a result, they were able to deliver the completed design in just 13 weeks. The core communication tool was the 3D PDMS model. 'Not only did the level of detail and refinement of the model astonish the client,' Jim said, 'but our management were very supportive of the value PDMS gave to this process. And because AVEVA had supported us closely throughout, it was also recognised that they were a good partner to work with.' AVEVA E3D shaves 40% off delivery times The Abu Tubul project had shown the importance of generating all design deliverables directly from the 3D model, so Jim's interest was piqued by a demonstration of AVEVA E3D's Draw module, which enables the rapid generation of 2D deliverables. 'It looked easy to use,' he said, 'so we trialled AVEVA E3D. We found that getting drawings out in this way would reduce the delivery time of structural drawings by 40%. That's a lot; 40% saves a lot of money, especially if you're looking at massive projects such as the Apache Energy project.' In addition to the challenge of creating fast and accurate deliverables, the majority of Atkins' projects are brownfield ones with difficult access conditions and often inaccurate or incomplete as-built information available. Traditional surveying techniques can be slow and costly. 3D laser scanning offers a much quicker, cheaper and more efficient alternative; large areas can be accurately scanned in a very short time. Getting the survey data still remains a critical-path activity, but AVEVA E3D's point cloud integration can dramatically shorten it. 'Instead of waiting weeks for the information we need, we can get it in two days,' Jim enthused. 'BubbleViewâ„¢ enables you to rapidly check the 3D design model against the scan to detect clashes. It's very neat. It's very quick.' (continues) AVEVA World Magazine 2015 | Issue 1 p12
