PLANT transferred with no human interaction. Aker Kvaerner expects this feature to be a major timesaver. In fact, with 2,000 to 3,000 document transfers a month, the company estimates it will save about 50 hours of labor each month. PROJECT OVERVIEW Plant Wansley Units 1–2 FGD Addition Organization Southern Company-Birmingham Contracts (Data sources) Default information structure for all contracts. BE Awards Category Plant Structural Analysis, Design, and Documentation Project Objective Retroﬁt two coal-ﬁred boiler units with scrubbers to reduce sulfur oxide emissions from the Plant Wansley steam plant Document creation/import Wizard Document creation/import Wizard (Plants, Oilrigs) Each facility with it’s own CAD configuration Facilities Project Identification Each facility can have multiple M&M projects (Data collected from Engineering register) Technical document- & equipment register (Meta data sent to PW) Engineering register v ProjectWise interface in distributed projects Aker Kvaerner is continually updating its engineering environment with new functionality and additional customer sites. The next phase in the project will add several international sites. “The ProjectWise-based integration has already proved successful in not only managing the complexities of the data integration and workﬂow, but also in simplifying the administration and support of the systems and data,” concluded Turner. reaction removes sulfur oxides from the ﬂue gas. In this process, gypsum is formed as a by-product. The cleaned ﬂue gas is then sent to the atmosphere through a new stack. Additional components are also required to dewater the gypsum. Fitting scrubbers into an existing plant layout is no small feat. A typical ductwork cross section is 28-feet-wide by 39-feet-tall, elevated 60 feet above grade. In all, the Plant Wansley FGD project requires 2,800 feet of ductwork and 5,400 tons of structural steel to hold the ductwork in place, as well as several tanks and auxiliary equipment including centrifugal booster fans, oxidation air blowers, and pumps. Detail design of the FGD addition began in the fall of 2004. To achieve signiﬁcant savings through volume procurement of materials, the design schedule was compressed to combine the structural steel and ductwork bid packages with another on-going scrubber project. Modeling large structures BE Award Winner Committed to Cleaner Air Flue gas desulfurization project contributes to a cleaner environment The project team used Bentley products to meet the time constraints and develop a project plan that would keep the coal-ﬁred units running at all times, except for scheduled outages. “The tight integration S ince the early 1990s, Southern Company has made an important effort to retroﬁt environmental controls at aging power plants, and the energy company is investing considerable resources to lower emissions of sulfur dioxide, nitrogen oxides, and mercury. Retroﬁtting existing coal-ﬁred units with scrubbers reduces sulfur dioxide emissions signiﬁcantly, enabling these plants to meet the more stringent regulatory requirements of the Clean Air Act. The Flue Gas Desulfurization (FGD) project at Plant Wansley, located near Carrollton, Georgia, is one such initiative. Plant Wansley has two coal-ﬁred units and two combined-cycle natural gas-ﬁred units. Adding scrubbers to the two coal-ﬁred units requires constructing ductwork to carry ﬂue gas from the existing stacks to a jet bubbling reactor, where limestone slurry is injected and a chemical v Southern Company performed structural analysis of the ductwork and structural steel in a single combined model, then extracted the drawings for fabrication and construction 40 BE MAGAZINE | Volume 4, Issue 4
