Biggest Piled Breakwater in the World

About The Project

Led by a Limak-Kolin Joint Venture, ARTI Proje prepared the construction designs for Çandarlı Port, Turkey’s biggest port and one of the world’s ten biggest container ports.

With a final capacity of 10 million TEU, Çandarlı Port is an extremely important and at the same time challenging engineering project due to the importance it carries for the regional port sector and the technical difficulties the project involves. Being constructed on an area with challenging soil conditions, the breakwater has been designed as a piled structure.

Our Work Scope

During the design stage of the project, design parameters were determined by conducting detailed physical and numerical model experiments. We also have provided the contractor group with consultancy during the construction stages of the project.

Çandarlı Port is Turkey’s biggest port and among the world’s ten biggest container ports having a maximum capacity of 10 million TEU.

Owner: Republic of Turkey Ministry of Transport and Infrastructure

Contractor: Limak-Kolin JV

Investment: 3.1 billion USD

The completion date for the project is the end of 2013.

Piled Breakwater

The wave protection for the Çandarlı Port is provided with a rubble mound breakwater along the first 500 m and piled breakwater along the 1,200 m after 10 m water depths. The width of the piled breakwater is 16 m. The piles are contiguous in both sea and harbor sides with 12 m center to center. The diameter and the thickness of the piles are 70” and 25 mm respectively.

Rockfill is designed under the piled breakwater to shorten the unsupported length of the structure for serviceability limit values due to unfavorable soil conditions.

Physical Modelling

A physical model study was performed in Middle East Technical University in collaboration with the Contractor, the Ministry of Infrastructure and Transportation. The study aimed to determine the permeability of the piles for different spans and verify the wave loads used in the design.
