The provision of adequate blast resistant walls is an integral part of the design of many industrial applications such as an offshore topside structure where they are required to protect personnel and safety critical systems from the consequences of an explosion and subsequent fire. Many designs of existing walls prior to the Piper Alpha Tragedy shown below, were firewalls and only considered low blast pressures in locations around the well head. A recent joint industry project has addressed key issues relating to blast loading and fire characteristics which culminated in the full-scale testing of a topside module. This illustrated that pressures of several bar are possible which can result in severe structural damage. As a result, many platforms require retrofitting to provide additional capacity.  Operators
are now required to submit safety cases to the authorities
having jurisdiction and Safety Executive to demonstrate how
major hazards have been identified and reduced to as low as
reasonably practical. The focus of this project was to develop a
novel method to upgrade existing firewalls and blastwalls in
conjunction with key organizations in the offshore industry.DuraSystems engineers wall and barrier systems that provide explosion and blast resistance followed by prolonged fire exposure. Designed specifically to protect personnel and equipment from the effects of explosion, fire, impact, and the effects of smoke and fumes in hazardous environments, such as offshore oil and gas platforms, petrochemical installations, chemical plants, military establishments, and hazardous process plants. Predictive engineering is important. In reality only a limited number of large scale tests can be performed due to the cost and safety implications. The development of efficient simulation tools is a necessity if improved safety is to be maintained. It was important to correctly model the strain rate effect using reliable material data at the weld boundary. DuraSystems has this tool. DuraSystems in conjunction with the Steel
Construction Institute developed a computer program that
provides predictive engineering. The FireBlast system as it is
called, can DuraSystems’ FireBlast program is used to determine the structural requirements for blast walls and partitions. Structures designed by the FireBlast program and DuraSystems’ DuraSteel offers significant protection from hydrocarbon blasts and fires. These walls and barriers are H (hydrocarbon) rated fire rated and can be engineered by the FireBlast program up to 2 bar blast protection.

design blast resistant walls and barriers that resist blasts and
post blast fires. The FireBlast program has been tested on large
scale tests that prove it simulates the effects of blasts and
has achieved Lloyds of London approval. Any wall or barrier
designed by the program will have a Lloyds Register
certification that acknowledges its approval. This approval is
something that very few if any other companies have obtained.
