Project Overview
APIE's tremie pipe equipment was selected for a $350M marine terminal expansion in the Middle East, requiring the construction of a 1.2km submerged concrete barrier to protect the new terminal structure. The project involved placing 18,500 cubic meters of specialized marine concrete in open water conditions with significant wave action.
Challenge
The contractor needed to maintain continuous concrete flow across the extensive barrier length while overcoming turbulent water conditions that threatened to compromise structural integrity. The tight 18-month timeline required simultaneous operation of multiple tremie systems without interference.
APIE Solution
We engineered a customized tremie pipe system featuring:
-
Modular tremie sections with standardized 260mm diameter for interchangeability
-
Corrosion-resistant coating specifically formulated for saltwater exposure
-
Integrated tremie hopper system with large-capacity receiving chambers
-
Advanced alignment technology for precise placement despite wave action
Results
The specialized tremie pipe system enabled exceptional project performance:
-
Uninterrupted concrete placement for 42 consecutive hours when needed
-
Perfect alignment maintenance of the protective barrier within 0.5° tolerance
-
Zero work stoppages due to equipment failure across the project
-
23% cost savings on labor compared to initial projections
-
Received "Excellence in Engineering" award from the port authority
