Every Technip Energies engineering project adheres to both our clients’ requirements and our own strong values: quality, compliance and respect for health, safety and environmental concerns."

Alessandra Marrucci, Global Engineering Director

Technip Energies’ engineering capabilities cover engineering studies for pressure vessels, rotating equipment, instrumentation, electrical facilities, computing, piping, civil works, cost control and scheduling for facilities and revamps. All types of engineering studies are fully managed within our company.

We offer our customers further engineering studies based on powerful engineering tools and work processes. Based on the nature of the project, engineering studies will include all or part of the following steps:


Years of experience in engineering innovation




Operating centers

Basic Engineering Design (BED)


The basic engineering design covers:

  • Conceptual process studies (material balances, process flowsheets, etc) and preliminary plot plans
  • Preliminary piping and instrument diagrams
  • Definition and sizing of main equipment resulting in process specifications
  • Specification of effluents.
  • Definition of control and safety devices
  • All the basic studies required to support a basic engineering design package (BEDP) containing all data needed by a competent contractor to perform the detail engineering. These basic engineering studies may consist of consolidating a process package initiated by an external process licensor.

Front End Engineering Design (FEED)


Front End Engineering Design covers mechanical data sheets of the main equipment, starting from the process specifications issued during the BED and incorporating the specific requirements of codes and standards to be applied to the project. It also includes:

  • Thermal rating of heat exchangers
  • Preparation of tender packages for the main equipment
  • Development of process and utility piping and instrument diagrams released for detail engineering
  • Development of detailed plot plans and hazardous areas
  • Elaboration of the main piping, instrument, electrical and civil works layouts
  • All the studies to be performed before ordering the main equipment

Detail engineering

The detail engineering covers:

  • Purchasing of equipment, main and bulk
  • Thermal rating of heat exchangers
  • Development of piping and instrument diagrams released for construction
  • Development of detailed piping drawings, including isometrics and stress calculations
  • Development of detailed drawings related to instrumentation, electrical facilities and civil works
  • Management of vendor drawings
  • Cost and schedule control
  • Start-up procedures
