Topsides
The DORIS group has a long standing experience in designing topsides for all series and sizes of fixed or floating platforms, from the lightest wellhead platform with no processing to the largest drilling and production platform with complete rig package, full processing, all utilities and high POB accommodation.
Topsides with gross dry weight as high as 25,000 t and to be installed by floatover have been designed from conceptual to detail engineering.
Multidisciplinary teams have to be mobilized when designing topsides including HSE, Process, Structure, ICSS, Instrumentation and Control, Telecom, Electrical, PVV (Piping, Valves and Vessels), Mechanical (static and rotating equipment), Layout, HVAC, Architectural and Corrosion specialists.
The DORIS group benefits of a strong know-how and expertise in each of these disciplines, which are enhanced by an accurate and up-to-date knowledge of suppliers markets and a very good understanding of fabrication yards practices and constraints. The ability of our engineers to work together within multidisciplinary teams, with very close interaction and coordination between the different disciplines, is also key.
This enables the DORIS group to maintain a high efficiency and successfully perform schedule and cost constrained projects.
