Design procedures for blast, explosion and fire analysis of offshore structures

Explosions, fires and other accidents are major risks in the offshore industry. Extreme loads arising for structural from accidents create a challenge engineers in the design of safe and weight-efficient structures. The use of design procedures based on state-of-the-art computational technology allows for weight-optimised structural designs that meet defined safety requirements. The finite element method (FEM) and computational fluid dynamics (CFD) as a computational tools has been extensively used in the offshore industry. It has been applied both for global and local simulation to study the behavior of the offshore structures.

The following aspects are normally considered in order to achieve an optimum design for blast-resistant walls and partitions:

  • Definition of design explosion and fire loads
  • Establishment of the behavior of materials to be used for the design for high rate loads
  • Determination of the behavior and strength of walls by means of non-linear FE modelling

FE modelling for offshore structures resistant to explosions and fires

Design procedures for creating offshore structures resistant to explosions and fires are normally based on the selection of design principles such as deterministic, probabilistic and risk-based design.

Methods used in designing structures that are resistant to explosions and fires include simplified methods and non-linear FE modelling and analysis. FE models involve accurate description of modelling techniques including modelling of structures, materials, and fire and explosion loads.

Safety doors must be built to meet OSHA, MSHA, NFPA Standards, FM Global Standards, European ATEX Directives and other many other standards when needed. Our advanced finite element simulation-based design for blast, explosion and fire will help you to satisfy all aspect of regulations in design step.

The Vibration Fatigue simulation predict fatigue in the frequency domain and it is more realistic and efficient than time-domain analysis for many applications with random loading such as wind and wave loads.

Heat Exchangers: Simulation-Based Design for Thermal Performance Optimization

Heat exchanger analysis involves a combination of heat transfer in fluids and solids. The fluid carries energy over large distances, while the solids separate the fluids so that they can exchange energy without mixing. Heat exchangers are involved in a variety of application areas, such as water treatment, resource refinery, nuclear power, food and beverage production, refrigeration, and more.

Blast, Explosion & Fire: Blast Resistance Certification with Protection Against Ballistic Attacks for Windows, Doors, Buildings and Vehicles

Since it is a challenge to validate and optimise protective structures against blast loads using full-scale experimental tests, we have to turn our attention towards advanced numerical tools like the CFD and finite element method.
Contemporary design requirements associated with the protection of life and property often require consideration for blast effects resulting from either accidental or intentional explosions. Proper treatment of blast effects in structural systems requires specialized knowledge ranging from non-linear responses of structures to short-duration dynamic loading. Enteknograte’s Research engineers have extensive training and experience in managing all structural response considerations related to high-energy events, including blast design, explosion effects and mitigation, and finite clement modeling of blast events. Design and validation of structures against blast loads are important for modern society in order to protect and secure its citizen.
