Paper highlights how integrating structural steelwork and plant layout design can reduce project cost, risk and delivery time Aveva released ‘Bolting it all together,’ the latest in its series of business papers, which discusses how integrating structural steelwork and plant layout design can reduce project cost, risk and delivery time. The paper explores the considerable business advantage that EPCs and Shipbuilders, working on plant/offshore projects, can gain by using a specialized steelwork application that can be used efficiently within a plant design solution to support close, collaborative working through an entire design and construction project. “Steelwork often accounts for a disproportionate level of project risk, rework, and overruns in cost and delivery,” said Bruce Douglas, Senior Vice-President, EDS Strategy and Marketing, Aveva.  “It is common industry practice to subcontract steel detailing and fabrication to specialized companies, with most plant design solutions not extending to the steelwork design/fabricate/construct workflow. Communication links are therefore stretched in a process that demands close collaboration, resulting in general project inefficiency that can lead to costly rework and program overruns.” The business paper demonstrates the need for EPCs and Shipbuilders to consider solutions that enable the development of steelwork design concurrently with the rest of the layout

Macro Sensors Gauge Tank Volume Changes

This diagram shows the LVDT level sensor attached to the side of a tank using a flat-hook assembly. The high-permeability core follows the position of the stainless-steel float. The LVDT electronics sense the core position using magnetic induction. Output is a 4 to 20-mA instrumentation current loop corresponding to the position of the core in the LVDT body.

Configured with a float, Macro Sensors HSIR Series LVDT Linear Position Transmitters are serving as level sensors to measure liquid level changes from a few inches to several feet in gauging tank level volumes. In this LVDT level sensor configuration
