• Engineer and check Air-Cooled Heat Exchanges, which include bundles, plenums, recirculation units, steam coils, header walkways, caged ladders, maintenance platforms, spanning beams and pipe-rack support structures.• Author of CALQLYS (pronounced Calculus). An engineering software application designed to streamline the engineering design and detailing processes from start to finish. This application significantly reduced engineering cost, time and improves manufacturing efficiency. Includes sales cost estimating, thermal design calculations, all engineering design calculations, automatic AutoCAD drawing capabilities, and an engineering resource SQL server database. • Author of a next generation software application that automatically generates Autodesk Inventor 3D air-cooled heat exchanges and their linked 2D details drawings and BOM’s. Flat patterns are automatically generated for CNC programming and BOM’s are exported to a database application for accounting cost analysis, inventory and purchasing. • Review customer specifications.• Provide CALQLYS stress calculations for plug box and cover plate headers, tubes, steam coils and manifold piping. Also included are, nozzle load calculations, swage calculations, and von Mises pipe to header calculations.• Train new engineering personnel.• Working knowledge of ASME, Section VIII, Division I code for air-cooled heat exchangers.• Working knowledge of all API Standard 661, up to the 7th Edition, July 2013. • Working knowledge of TEMA “C” and TEMA “R” requirements for air-cooled heat exchangers.• Working knowledge of AISC and OSHA requirements for structural design.• Working knowledge of Mathcad.• Working knowledge of Sequel Server 2016 (or SQL) database.• Working knowledge of Visual Studio 2019, C# and VB.Net. (class files and API development)• Working knowledge of Java Eclipse. • Provide ANSYS FEA 3D static analysis for determining the limitations of nozzle reinforcement for job specific header designs.
