Structures that are powered by Tekla

Structures that are powered by TeklaTekla Structures enables an integrated structural design and detailing process that go to make it the ideal solution for the plant industryUsed worldwide by leading firms for the power generation and industrial process facilities, Tekla Structures enables an integrated structural design and detailing process that drives reduced project delivery times with improved quality, for significant cost savings on projects of any size, regardless of complexity. Tekla models can be shared with major plant design systems such as PDS, PDMS, SmartPlant 3D, during the FEED, detailed design phases, and continued downstream for the creation of steel fabrication deliverables as well as concrete/rebar detailing.Benefits of Tekla Structures technology

Model structural steel including connections, ductwork and access equipment
Model concrete, including rebar and embeds
Coordination of structural design with piping and mechanical systemsWorking with structural analysis programmes such as STAAD.Pro, GT-Strudl, SAP2000, etc.
Creating high quality 2D drawings that update as the model changesGenerating accurate, detailed BOM’s
Supplying an accurate model to fabricator or rebar detailer, ready for shop detailing and manufacturing
Allows the project owner to have full control of the project progress.
According to the company, Tekla Structures is being used by Alstom Power, Atomic Energy of Canada, Bechtel, Black & Veatch, CB&I, Foster Wheeler, Hitachi Power, McDermott, Dow Chemical, Saipem, Shaw Power, SNC Lavalin, Westinghouse, L&T MHI.A few projectsSuper Thermal Power Plant, Nigrie, Madhya pradeshLarsen & Toubro (L&T), a technology-driven engineering and construction organisation, bagged a contract from Jaiprakash Power Ventures (JPVL), a power vehicle of Jaypee Group, for the supply and erection of the boiler and steam turbine and generator (STG) islands for the two 660 MW Jaypee Nigrie Super Thermal Power Project. The part of the contract for the boiler island has been given to L&T-MHI Boilers (LMBPL).Jaypee Nigrie super thermal power project comprising two 660 MW super-critical unit will be set up by JPVL at a site in Nigrie village, Singrauli district in Madhya Pradesh. L&T MHI has done the model-based integration from conceptual design to structural engineering up till fabrication. This boiler structure comprises of  steam/water cooled furnaces with separators, water wall headers, Super heater and re-heater system, spring loaded safety valves, attemperator system for super heater and re-heater system, economiser system, tri-sector type regenerative air heaters, steam coil air pre-heaters (scaph), integral piping, air & gas ducts, buck stays & tie bars, soot blowers, raw coal bunkers and supports & chutes, pulverisers, fuel piping, flash tanks, garbage chutes, cable trays, roofings, side claddings, galleries, walkways, platforms, and all other auxiliaries and equipment etc.From this detailed boiler structure of approximately 15,000 MT almost 20,000 part drawings and 13,000 assembly drawings were extracted during detailed engineering stage. This model involves all the complexities with respect to layout, interfaces with all piping and ducting equipment/system as well as their operation and maintenance requirement.B K Chaurasia, Structural Head (L&T MHI) mentioned that by adopting Tekla structures there were huge productivity gains and reduction of engineering time cycle. He further cited that Tekla Structures has also helped them in eliminating duplication of efforts at various stages of analysis, design and detailing and thereby achieving complete freedom from risks of errors, misinterpretation and rework due to the errors slipping to the construction site. Thermal Power Station, WaiGaoQiao, ChinaAlstom Power Boiler became familiar with Tekla during the Wai GaoQiao coal power station project in China. Until then, the company had been using other plant design and engineering software and knew little about the finer details of modelling with Tekla Structures. A subcontractor involved in this project had been among Tekla’s customers for some time. As a result of this collaboration, it became necessary to confront the issue of data compatibility between Tekla Structures and the software that Alstom was using. The flexibility of Tekla Structures was used to maximum effect, ensuring seamless cooperation which led to the entire project being concluded successfully and on time.Intergraph software was used to plan the systems, and external 2D software was used to handle the parts for the basic engineering. Workflow inconsistencies initially led to the parts being rejected in the planning process, which Tekla Structures managed to deal with later on. In this project, the ability to import microstation format (DGN) reference models and to carry out high quality importing and exporting of object-oriented SDNF files was of great help. This was a decisive advantage for planning and modelling extensions to the existing construction. In conclusion, this kind of data compatibility guarantees success in international projects. After the work on the Chinese coal power station project was successfully completed, the modelling licences were transferred to Germany and have since been used by the company in Stuttgart.To know more about Tekla Structures solution for plant industry:Contact: info.india@tekla.comTele: +91-22-61387777
