    Regardless of the size or complexity – Aibel has the answer


Aibel has developed unique expertise in the development, design, construction and engineering of process modules for jack-up rigs.

MOPUD illustrasjon 2

MOPUD stands for mobile production unit with drilling. The concept involves modification of a jack-up drilling rig through the installation of a production module that allows the rig to be used for both drilling and production. The concept is flexible and is therefore relevant to both newbuilds and upgrades to old rigs.

Ideal concept for marginal fields
With the process module designed by Aibel, a rig can also carry out the processing of the oil. When production in the field is complete, it is easier to close down the wells and leave the field.

Tried and tested concept
In 2007, Aibel supplied a process module to the Mærsk Inspirer jack-up platform in the Volve field. Since then, the platform has had high regularity and production from the field has exceeded all expectations.

Unique expertise
There are restrictions concerning weight and space on board. This makes the design and construction work especially challenging. Aibel has optimised the design through multiple studies and the solution has been adapted for different rig sizes and classes.
