 Forensic Engineering

Tools of engineering to find the cause of the failure or accident is forensic engineering

  • System Failures

  • Accident Reconstruction

  • Laboratory Testing

  • Finite Element Analysis / FEA

  • Simulation of Failure

  • Material Failure Analysis

  • Expert Witness

  • Second Opinion / Independent Third Party

 Accident Investigation

Accident investigations for property damage, injuries, and fatalities, including the effects on business interruption and extra expense

  • Public and Private Sector

  • Self Insured Corporations

  • Insurance Captives

  • Investigation for Reinsurance Companies

  • Corporate Legal Counsel

  • Public Legal Counsel

  • Insurance Claims

  • Insurance Subrogation

Our forensic engineering and accident investigations affords you the information you need to find the causes of your failure or accident.  You can have the features of our mechanical event simulator where the failed part is deformed until breakage or damage by using our time elapsed finite element analysis (FEA) graphics.  This excellent tool proves your position and clearly shows the engineering truth of the failure.

Question: If you have an accident like an explosion or equipment damage can you afford a recurrence?

If you or your client has had any of the following accidents or failures with the following equipment call us...we can help you.

Boiler: Watertube, Firetube, Cast Iron, Electric Steam Generator

Furnaces: Ovens, Boilers, Fluidized Bed, Kilns, Condensing Furnaces

Pressure Vessel: Air, Vacuum, Process, Chemical, Steam, Water, Condensate

Piping and Pipe

Aboveground Storage Tank / AST:  Water, Chemical, Petroleum, Fuel Oil

Machinery: Water and Steam Turbines, Presses, Rotating

Electric: Transformers, Electric Distribution Equipment, Generators, Motors

Our staff will get to the cause of the failure or accident by using analytical charting tools to help reconstruct the accident.  Accident reconstruction can help you understand the evidence when there is a complex chain of events that cloud the truth. 

Insurance employed accident investigators for claims handle many claims in a day and may not give your accident the detail needed to bring the engineering truth out.  Question: Can you afford that?

AIS specializes in accident investigations to expert witnessing from furnace explosions and boiler steam explosions to wreckage and electric arcing damage to equipment failures and claims investigations on-

  • Steam Explosions

  • Furnace Explosions

  • Condensate Explosion

  • Water Hammer

  • Tanks Ruptures

  • Piping accidents

  • Turbine Wrecks

  • Press Failures

  • Arcing Damage

  • Electrical Insulation Failures

Explosion of Pressure Vessel by Gas: TNT Equivalent [kg]

The results are approximate and only based on gases in a pressure vessel and NOT a mixture of liquids.  A Forensic Investigation or Engineer needs to be consulted in all cases.  This is for information only.

 

Operating Pressure, MAWP

or Test Pressure
MPa

Convert psi to Pa

Example:

150 psi x 0.00689= 1.03MPa

Volume of Pressure Vessel


m3

Convert cubic Feet to m3

Example

150ft x  0.02831 = 4.2365 m3

Atmospheric Pressure outside Pressure Vessel

MPa

Ratio of Specific Heat or Gas inside of Pressure Vessel


 

Specific Heat Ratios

H2 = 1.41

CH4 = 1.31

O2 = 1.40

N2 = 1.40

Propane= 1.31

Steam = 1.33

Acetylene = 1.24

Natural Gas = 1.27

Butane = 1.09

TNT [kg]

TNT [pounds]
