Project Engineering: Spare Reboiler Installation


A refinery situated in the United Kingdom required a detailed engineering package for a project to install a second reboiler for the existing crude unit naphtha stabiliser.


InSite Technical Services project engineering team executed the detailed engineering from the client’s basis of design, including:

  • Reviewing the sensitive hydraulics of the thermosiphon reboiler.
  • Preparation of the exchanger datasheet.
  • Detailed calculations for piping stress analysis, nozzle loadings, and civil & structural loadings.
  • 3D model, piping isometrics, civil & structural and instrument & electrical drawings.


  • Project deliverables produced to a high standard, minimising contractor Technical Queries or changes during construction.
  • Project design met client schedule.
  • Project communication and understanding maintained with key stakeholders throughout the project to ensure success of construction and operating phases of the project.
