Conceptual & FEED

Conceptual & FEED Engineering

Conceptual and FEED are the phases when the most value can be brought to a project



Major cost optimisations can be achieved during these phases.


This is why the DORIS group strives to understand client’s needs. Our teams work in a partnership mode from the start of the project.


The DORIS group has developed the “Fit-For-Purpose” methodology and tools, which provides considerable CAPEX reductions. This methodology has already provided major CAPEX reductions to several of our clients.




During Conceptual and FEED, construction, installation, operations and maintenance are to be included in the design to ensure proper operations by the client during asset life.

From Conceptual and FEED phases, The DORIS group teams design the facilities ensuring that each phase of the development will be achieved safely.
