Project Name: New Container Terminal & Dredging Project in Sudan Port

Host Country: Sudan

Project Duration: January 2007- February 2011

Project Content：

The New Container Terminal & Dredging Project in Sudan Port includes 2 nos. 70,000TEU Container Terminal, terminal apron roads, revetment, dredging, and land reclamation, and a navigation and sightseeing lighthous.

Terminal: the construction length of the whole terminal structure is 861.84m, including 781m for the main terminal, 40.24m for the transition section at the southeast end, and 44.6m for the north end. The South revetment is 1332m long, the North revetment is 87.76m long (connecting the 44.6m-north end), and the road area is 34832.6m2. The terminal is designed as a gravity caisson structure, which is divided into upper and lower layers. A total of 4157 components are required to be prefabricated, including 486 caissons, 246 unloading plates, 446 gratings, and pipe trench covers and sleepers. The weight of each caisson is within 200t; The bottom of the caisson is a riprap of the foundation bed, with a thickness of 2-6m. The top of the caisson is a prefabricated unloading plate and parapet from concrete pouring; Dredged material (coral stone) is dumped and filled behind the caisson as a decompression prism and inverted filter; The rear track adopts a reinforced concrete structure.

Dredging: the total dredging volume is 7.65 million m3. The geology of the foundation trench and the harbor basin is coral reef geology, and the adopted technology is rotary drilling cutter-suction.

Characteristics and Significance of the Project：

1.The application of "Four-New Technology" in the project. It is situated in a desert area with high temperatures and large daily temperature differences, the project approves the mixing of polypropylene fiber into the concrete to prevent or reduce the occurrence of concrete shrinkage cracks. This approval can prevent or reduce the occurrence of shrinkage cracks due to water loss at the plastic stage of the concrete when the deformation modulus is low, and ameliorates the deformation characteristics and toughness of the concrete.

2.Our concrete construction faces a great deal of challenges due to the high temperature and big gap in temperature in Sudan, which is linked to the poor quality of local raw materials. The project department has controlled the concrete quality through raw material control, concrete mix proportion adjustments, polypropylene fiber addition, and other channels. Hence acquired a betterquality at the end of the whole project and the owner being highly praised.

3.Innovation of the project fund mode. The method of deferred payment is endorsed to solve the owner's problems in situations whereby the owner of Sudan Port is short of funds and urgently needs to carry out port construction. On one hand, the completion of the port berth on schedule has expanded the scale and enhanced the profitability of the owner; on the other hand, it has relieved the owner's short-term financial difficulties and strengthened the long-term cooperation between the two parties, thereby laying a foundation for a subsequent continuous contract of Sudan Port projects and a stable market in Sudan Port.

4.Promotion of the engineering application research of coral reef limestone. Based on the project, thorough research, theoretical analysis, indoor and field tests, calculation simulation, and other methods, is systematically carried out to research on the basic physical and mechanical properties of coral reef rock and soil. The effective detection of different reinforcement methods of coral reef rock and soil backfill in the container yard, the optimal design of pavement structure, the settlement characteristics and stability of the gravity structure foundation of the coral reef rock foundation, clarified the physical and mechanical properties of coral reefs in the Red Sea area, thus obtain the design parameters suitable for the red sea coral reef backfill foundation. The project successfully solves some key technical problems in engineering design and construction such as providing relevant design parameters and theoretical basis, saves the project from cost, and has good social and economic benefits.

5.All-round integrated services for the owner. According to the natural coastline of Sudan, the economic development of Sudan, the needs of the owner, and the long-term business layout of the company, merged with other services from financing, consulting, planning, design, construction, and equipment supply to the port operation have formed in the Sudan Port market.

6.The project won the 2010 Quality Engineering Award of CHEC.

7.The project is the largest port project with the most advanced port machinery supporting facilities in Sudan so far and the Berthing Capacity of the terminal increased to 70000 tons. A successful operation of the terminal is of great importance to the port logistics of Sudan and even the whole of northeast Africa, which has effectively increase the import and export trade volume of Sudan Port and is of great importance to the overall development of Sudan's national economy.
