Project Number 429
Date of Summary June 10, 2004
Subject Oil Platform Removal Using Engineered Charges:  In Situ Comparison of Engineered and Bulk Explosive Charges
Performing Activity Canadian Commercial Corporation/SNC Technologies Corporation (Subcontractors)
Principal Investigator Pierre Pelletier
Contracting Agency Minerals Management Service
Completion June 2004
Description  
Progress The final report was accepted in June 2004. The general conclusions of this study are that the values of peak overpressure, impulse and energy flux density obtained from both the engineered and the bulk charges generally follow the accepted exponential shape when presented as a function of the distance from the blast charge divided by the cube root of the charge weight. These values are also closer to those computed with the Conner similitude equation than those obtained with the ARA model which can be expected based on the method used to obtain the equations and the conservative assumptions used to develop the ARA model. The limit values of 12 psi for the peak overpressure and 182 dB (re 1 uPa2-sec) for the energy flux density are obtained at half the distance for the 4.05 pounds engineered charge than the 50 pound bulk charge. Additional experiments should be performed to confirm more precisely the results obtained.
