Our Added Value

For over 50 years

involved from conceptual to detailed design and execution, the DORIS group has striven to make projects more profitable, delivered earlier and safer.


  • We challenge to optimize CAPEX and OPEX
  • We deliver on time, and challenge to optimize the schedule for earlier production
  • We analyze early and mitigate the risks early, to make projects more profitable and safer.

Because we are independent

  • and we design facilities which are adapted to client needs. We do not sell a particular product or a particular vessel. But, as we are in a central position in the industry, we know the latest technologies and the capacities of each option
  • The DORIS group has developed the “Fit-For-Purpose” methodology, providing considerable CAPEX reductions while ensuring safe and reliable developments.

Our employees have, on average, been in the company for 15 years. Therefore

  • they are fully committed to DORIS success, and so fully committed to client success
  • This allows a strong reactivity and a collaborative spirit
  • Our teams have cumulated an incomparable experience
