Petkim Quay No. 2 Strengthening Project, Construction, Installation, Implementation, and Berth-Front Dredging Works

Quay 2, originally constructed in the 1970s and having reached the end of its economic service life, was completely demolished and replaced with a modern piled quay structure with high load-bearing capacity. Within the scope of the project, the existing block-type quay was dismantled, dredging works were carried out in front of the quay, and a new piled quay with an approximate length of 445 meters was constructed to enable the safe berthing of larger and higher-tonnage vessels.

To achieve the required operational depth in front of the quay, seabed dredging was performed down to the –12.00 m level, and the dredged material was transported to approved disposal areas.

As part of the load-bearing system of the new quay structure, steel pipe piles with a diameter of Ø1016 mm, a wall thickness of 16 mm, and manufactured in S355JR grade were driven from land. Accordingly, the quay substructure was formed using a total of 473 steel pipe piles, comprising:

208 piles with a diameter of 914 mm and a length of 28 m, and
265 piles with a diameter of 1016 mm and a length of 32.5 m.

The load-bearing capacities of the piles were verified through PDA (Dynamic Load), Compression, Tension, and Lateral Load Tests.

Within the scope of the superstructure works, high-strength marine concrete (C35) was used for the construction of capping beams, gravity blocks, anchorage systems, and precast elements. In addition, each pile was filled with C35 concrete to enhance structural integrity and durability. Bored pile works were also carried out as part of the project.

To maximize the safety and efficiency of port operations:

Quick Release Hook systems were supplied, installed, and commissioned, and
100-ton capacity bollards and fenders were installed.

In line with long-term durability and sustainability objectives, cathodic protection systems were applied to the steel piles, and concrete surfaces were impregnated with water-repellent materials. In the backland area, 30 cm thick, helicopter-finished C30 concrete pavement works were completed.
