Client: ALUMINIUM BAHRAIN (ALBA)
Consultant: FATA SPA
Project Overview:
The ALBA Port Upgrade project heralds a new era of efficiency and capacity enhancement at the esteemed Aluminum Bahrain (ALBA) Port. Under the astute consultancy of FATA SPA, this initiative focuses on the construction of cutting-edge alumina and calcined coke silos, revolutionizing storage capabilities and bolstering operational resilience.
Project Description:
Alumina Silo:
- Construction of a state-of-the-art Alumina Silo with a remarkable 50,000-ton capacity, featuring dimensions of 42 meters in diameter and 43 meters in height.
- The silo’s foundation, supported by 227 meticulously installed 1.0-meter diameter piles, spans an expansive area of 1878 square meters, boasting a robust 1.4-meter-thick pile cap.
- Impeccable craftsmanship is evidenced by the installation of 860 tons of reinforcement steel and the pouring of 2470 cubic meters of high-strength concrete for the foundation.
- Utilizing the slipform method, a formidable 500mm thick silo wall, standing at a towering 42 meters in height, was meticulously constructed in a remarkable 23-day period.
- Post-tensioning of the silo wall with 150 tons of strands ensures structural integrity and longevity, with approximately 10,000 meters of post-tensioning ducts employed in the process.
Calcined Coke Silo (CPC):
- The construction of a cutting-edge Calcined Coke Silo boasting a 20,000-ton capacity, featuring dimensions of 30 meters in diameter and 62 meters in height.
- Supported by a robust foundation consisting of 116 1.0-meter diameter piles and a substantial 1.6-meter-thick pile cap spanning 882 square meters.
- A meticulously executed elevated slab, measuring 600mm in thickness and situated 6.00 meters above ground level, is complemented by a second elevated slab, 1850mm thick and positioned 14.00 meters above ground level.
- The slipform construction method facilitated the creation of a formidable 500mm thick silo wall towering at 62.0 meters in height, completed with remarkable efficiency in just 21 days.
Post-tensioning of the CPC Silo wall with 100 tons of strands ensures structural stability, with approximately 7,400 meters of post-tensioning ducts utilized for reinforcement.
