In collaboration with international contractors and partners, we have developed the ASSIST (Advanced Subsea Intervention Support & Technology) pipeline repair system. Featuring large bespoke equipment, this unique system features first of its kind technology for this region.
Introducing ASSIST
Rapid Mobilization
Swift mobilization from its purpose built facility at KEZAD to Khalifa Port
Cost Reduction
Asset Risk Reduction
Subsea Pipeline Management
Pioneering Technology
Gas Supply Recovery
Creating Value & Impact
ASSIST is poised to have a strong, positive impact on the oil and gas industry and the region across three key areas:
Asset Integrity
The subsea repair helps reduce pipeline exposure to seawater, protects onshore assets and eliminates the risk of leaks (by returning the pipeline back to its original state).
Technical Innovation
The diverless subsea launcher & receiver design already covers 36-inch and 48-inch pipes but can be replicated for smaller sizes, significantly reducing the investment required.
Competence Development
ASSIST has brought together many industry subsea expert companies and operations ensuring the development and retention of subsea repair competence and expertise for the local market.
