Most innovative technology that uses high-density C02 as a form of blast medium, which eliminates the need for extraction, waste removal, and encapsulation. The process also offers you the opportunity to blast and paint at the same time. Used for removal of heavy corrosion, epoxy coatings, PFP coatings and hard scales and is the world’s first corrosion removal system using dry ice. The world’s first mobile high-density dry ice production system and are pioneers in offshore dry ice blasting projects. Significant savings due to the reduction of site preparation, clean-up costs and waste disposal costs as there is no waste as the ice evaporates. Significant time saving as it takes on 25% of the total time compared to traditional methods (eg. Grit blasting).
Recent tests have achieved the following results, following blasting with our system:
Cleanliness inspection – in line with SA2.5 standard
Profile reading – 70 microns after blasting Cat D corroded surface
Salt readings – 0 after blasting the above
Adhesion tests – readings of 15-27MPa achieved on the above surface after recoating
Generating a new surface profile
DI Global carried out TSA testing with the Shell TRT department.
Tests past which proved the DIG MM system is capable of producing a surface cleanliness & sufficient profiles to pass TSA adhesion and bend tests.
Technology achieves significant savings due to the reduction of site preparation, clean-up costs and waste disposal costs.
SAFETY AND ENVIRONMENT
Technology is safe to use, with reduced hazards to the operator and surrounding environment. The CO2 we use comes from recycled sources.
Our client list includes the following:
• Shell, Total, Valero, Nexen, EnQuest and Brunei LNG
The table below documents a recent case study and the savings that were achieved. The time savings were realised through the lack of encapsulation and clean-up, completing the scope in just under 25% of the time for traditional methods.
