After the conception design phase and feasibility studies a project enters the engineer phase during which engineering  studies which may include, according to the type of project:

  • process 
  • pressure vessels 
  • rotating equipment 
  • instrumentation 
  • electrical facilities 
  • computing 
  • piping, civil works 
  • cost control and scheduling 

All these types of engineering studies are covered and fully managed within Technip.


According to the nature of a project, engineering studies will includes all or part of the following steps:

Basic Engineering Design (BED) covering:

  • Conceptual process studies (material balances, process flowsheets,…) and preliminary plot plan. 
  • Preliminary Piping and Instrument Diagrams. 
  • Definition and sizing of main equipment resulting in process specifications. 
  • Specification of effluents. 
  • Definition of control and safety devices. 
  • And, generally speaking, 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) covering:

  • 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 in question. 
  • 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. 
  • And, generally speaking, all the studies to be performed before ordering the main equipment. 

Detail Engineering, covering:

  • 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.
