Protection Series – Blast Proof Modules

Protection Series – A module blast shelter

Containerized buildings and enclosures have shown time and again to be an efficient way to reduce time and costs when adding new buildings or facilities into existing onshore process plants and other offshore areas with an explosion risk. This is especially true when there is limited production downtime during yearly maintenance, etc.

The limited window of time to install a fully functional building makes containerized modules a very attractive option in order to resolve this challenge for many clients in a very cost-effective way. 

But can a containerized building withstand blasts and fire in the same way as a site-built concrete building?

Blast resistant module

Over the last 10 years Uniteam has proven that both smaller enclosures and larger Temporary Refuge (TR) buildings can be made out of modular structures, which can be tested and approved ahead of delivery, and with very limited time on site before your building is sealed and production on the plant can start again. The end result is a cost-effective means to protect your workers in dangerous areas by use of a blast-proof Temporary Refuge.

Considering the strength of the blast building

How to consider and evaluate the blast risk situation?

First, you need to evaluate the risk of the potential blast which can occur where the buildings are to be placed, then consider the strength of the building to withstand the potential blast.

Uniteam will calculate the physical conditions of the modules with an FEA analysis, and reinforce and produce the customized modules to be used in each situation. Further on, they are fabricated in our workshop in Oslo, Poland or China, and the blast-resistant modules are ready for sale and delivery to clients all over the world.

Achievable blast pressure

What blast pressure can we achieve with our modules? Uniteam has delivered solutions from 0,1 – 0,8 Bar blast pressure.
