FEED (Front End Engineering Design) Part 1

 FEED (Front End Engineering Design) Part 1

FEED (Front End Engineering Design) means Basic Engineering which is conducted after completion of Conceptual Design or Feasibility Study. At this stage, before start of EPC (Engineering, Procurement and Construction), various studies take place to figure out technical issues and estimate rough investment cost. This work is normally contracted to EPC contractors, as an optional contract or through bidding. The product of the activity is called “FEED Package” which amounts up to dozens of files and will be the basis of bidding for EPC Contract.
It is important to reflect client’s intentions and project specific requirements in to the FEED Package without fail, in order to avoid significant change during EPC Phase. The FEED Work takes about 1 year in case of a large-sized project such an LNG plant. As it is essential to maintain close communication with client, it is a common practice that client stations at Contractor’s office during the work execution

Types of FEED is a light, normal and extended FEED based on engineering deliverables and their depth and details depend on the client's demand.
