Engineering

A pioneering spirit

Over decades, DORIS has contributed to resolving the cost reduction and standardization challenges experienced by the global energy industry. As the originator of a fit-for-purpose, safe, and cost-effective engineering approach, DORIS is committed to leading the shift towards cleaner energies by providing innovative solutions.

DORIS is the international leader for delivering high quality engineering to the energy industry. We have been supporting our clients for almost 60 years, from concept to decommissioning phase, for onshore and offshore energy projects.

1

Conceptual
& FEED

Major optimisations in term of cost, safety, or environmental impact can be achieved during these early phases. For this reason, DORIS strives to understand clients’ needs to bring the maximum value possible. Our teams work in a partnership with clients from the start of the project to identify challenges and establish the basis of a smooth and efficient execution.

2

Detail Engineering
& EPCm

DORIS can execute detailed design in continuity of FEED or on a stand-alone basis. We can perform detailed design for Operators or EPC Contractors. Our in-house teams and our global execution centre are capable of mobilizing quickly, creating a strong and integrated team that can flexibly work during the execution phase.

3

Asset Integrity
& Life Extension

We understand our clients’ challenges, from ensuring that assets are fit-for-purpose to the importance of extending assets beyond their design life without compromising safety. DORIS has developed a holistic approach to the asset integrity and life extension process by considering physical degradations, obsolescence as well as human and organisational impacts.

4

Maintenance, Installation Engineering & Construction

From the initial commissioning phase to modification during the operation phase, DORIS guarantees the optimum installation of offshore and subsea assets. We support our clients with survey and associated maintenance program development and execution. With advanced technology, vessels and inspection solutions, DORIS provides adaptable solutions for its clients.

5

Decommissioning

Decommissioning poses operators with several challenges, particularly in terms of cost and environmental safety. These factors are often overlooked or only hastily assessed during the development phase. DORIS draws on its planning, engineering and operational expertise to develop decommissioning plans in a cost-effective manner and to ensure a swift handover with our clients’ operational and decommissioning teams.

6

GHG Reduction

As many of our clients move towards the production or distribution of cleaner energies, DORIS is ideally positioned to provide engineering services and technical solutions to lower the Green House Gas (GHG) emissions of the energy industry. Closed flare, asset electrification, and carbon capture and storage are some of the numerous solutions DORIS has developed for its clients to reduce methane and CO2 emissions.
