The repair process had to be carried out under full operating plant conditions.
THE CHALLENGE :
- A blast at the plant had caused extensive damage to the Ammonium Nitro-Phosphate (ANP) and Calcium Ammonium Nitrate (CAN) units. This was affecting production while compromising safety of the staff as well as posing an environmental threat.
THE ODDS :
- The project was under a tight deadline of 45 days in which to repair both units.
OUR RESPONSE :
- We began with a diligent evaluation of the distress in the structure
- We improvised the designing of a retrofit system to reduce the execution period of the project
- The damaged beam column junction was then retrofitted with ample grouting and a fibre wrapping system
