Case studies

Firewater on accommodation platform
A customer who delivers floating accommodation platforms needed help reviewing the design of their firewater system. The fire water system fulfills an extremely important task in the safety of the work on the platform and the system's function must therefore be ensured for all possible structural loads to which the system may be exposed.
Analyzes and structural loads
In the assignment, analyzes and pipe calculations have been performed on the fire water system in the software Peps/Pipestress and EditPipe. The structural loads considered in the calculations are pressure and temperature as well as loads from snow, wind, explosions and seismic loads. The results from the calculations are evaluated against current criteria for process pipes according to the standard ASME B31.3.
Customer benefit
With this assignment, we have helped the customer design a pipe system that is well adapted to the present structural loads and that meets the standard requirements regarding structural integrity. With approved calculations, the fire water system has now been installed on the housing modules and delivered to the buyer.
Calculations were made with Peps (Pipestress) och EditPipe
Design code:
ASME B31.3 (The American Society of Mechanical Engineers)
Project start:
Uniso was a part of the project during 2017
