With more than 200 projects successfully completed to date, Sedef Shipyard has been operating under its parent company Turkon Holding since 2000, which belongs to one of the most established families in the Turkish maritime sector.

Turkon Holding has roots dating back to 1954, when Kalkavan Family first started in shipping management. Within the 65 years that has passed since then, the Group has contributed to carrying Turkish shipping industry forward by creating two leading brands: Turkon Line in container transportation, and Sedef Shipyard in shipbuilding.
