DESIGN OF BREAKWATER FOR A NEW MULTI-CARGO PORT IN BLACK SEA

Filyos Port is planned as Turkey’s third largest port for multi-cargo handling including containers, dry bulk and break bulk. It is located at central Black Sea coastline ofthe country, presently a greenfield area with long sandy beach. When completed, it will have total container throughput capacity of 1.5 million TEU’s and 20 millionton bulk cargo. The Port will have a 2,700 meters long main breakwater placed mostly at 10 meters water depth and 1,500 meters long secondary breakwater protecting theberths from harsh Black Sea wave climate. Various armor layer design options with tetrapod, accropode and xbloc units were investigated in the project and the final designwas developed with xblocs, which is also a first application with these units in the country. Construction of the port is presently ongoing and in the first stage breakwater construction is progressing ahead of other activities to provide a sheltered work area for the berth constructions to start. In this paper, basic design criteria employed and mainissues addressed in developing the design of the breakwaters will be discussed.
