GEMAK – The leading shipyard in Turkey is building an impressive portfolio of Greek clients
Gemak was established in 1969 by Naval Architect Mr. Ismet Uner as a small yard in “Golden Horn” in The Bosporus, Istanbul. All facilities were transferred to Tuzla bay at the Sea of Marmaras in 1981, which was designated as a ship repair and ship building area by the Turkish government. Following a demand-oriented investment policy, supported by the realistic vision of its founder, Gemak has become the leading shipyard in ship repair and conversion in Turkey. In 2000, Gemak acquired TGE Shipyard and entered the new building segment. By accomplishing the construction of a graving dock, TGE started to provide repair services, in addition to new building works. After completing the last new building project in 2011, TGE has become a pure ship repair facility. In 2005, in order to increase the capacity of TGE steel & pipe construction, pre-fabrication workshops were relocated to nearby Gebze. In Mr. Birol Uner, the Group’s CEO
2008, NETA Pipe & Steel Construction Industry S.A. was established as an independent firm in Gebze, providing services to Gemak Group
Mr. Murat Cengiz, GEMAK’s Marketing Manager, Shiprepairs
