In this position, you will take charge of both basic and detailed engineering strategies while managing external engineering firms and internal teams. You will also be responsible for creating engineering packages for piping and static equipment that meet construction needs.
Your Key Responsibilities
Perform thorough flexibility and computational pipe stress analysis utilizing Caesar II across various piping systems.
Design and assess pressure vessels according to ASME Section VIII Div 1 & 2, employing PV Elite or Compress software.
Provide detailed revisions on piping diagrams and isometrics to guide piping and structural design efforts.
Specify pipe guides, anchors, supports, and alternative materials or vendors to align with project timelines.
Review and assure the quality of 3D design work (Revit, Plant3D, CADWORX) by the Process Design Team, incorporating pipe stress and pressure vessel analysis feedback.
Develop bills of material for supports, guides, anchors, stops, flex joints, and expansion joints for procurement purposes.
Conduct dynamic analyses, including slug flow, water hammer, and flange leakage checks, utilizing Caesar II.
Execute Finite Element Analysis (FEA) for critical vessel junctions using FE Pipe or Nozzle Pro.
Communicate the implications of stress and vessel analysis on design and escalate any concerns related to schedule or material lead times.
Act as the Subject Matter Expert in piping and pressure vessel design, ensuring compliance with ASME and ASTM codes.
Mentor and guide junior engineers and high-value engineering partners.
