Project requirements

Specialist Services received a rental order from a client through Labtech Services Limited, a Specialist Services Company based in Aberdeen. The requirement included four 20ft office units to be converted into two bespoke units: a permit office and a tea shack.


The project was extremely complex in terms of deliverables for this multi-room, joined and pressurised hazardous area certified module.

In line with the client’s requirements and specifications, Specialist Services designed and modified four of their standard 20ft A60 office modules, by combining two 20ft modules as double-wide modular units, constructed to provide the permit office and tea shack. The modifications on the four modules were executed whilst maintaining all of the modules existing ATEX, DNV, A60 and CSC certification.


This was the first order Specialist Services received from the client and they had committed to an extremely short lead time of only 2 weeks. Due to the close coordination between Labtech and Specialist Services projects, engineering and production across all disciplines, the project was seamless in the execution phase and everything was successfully completed on time.
