What DİTAŞ Deniz İşletmeciliği ve Tankerciliği A.Ş. does

DİTAŞ Deniz İşletmeciliği ve Tankerciliği A.Ş. is a Turkish maritime services company founded in 1974, operating as a wholly-owned subsidiary of Tüpraş (Türkiye Petrolleri Rafinerileri A.Ş.) within the Koç Holding conglomerate. The company operates one of Turkey's most powerful and youngest Turkish-flagged tanker fleets, consisting of 17 vessels (including MR, Suezmax, Aframax, chemical product, and bitumen tankers) with a total carrying capacity of 712,000 DWT. The company is backed by TSKGV (Turkish Armed Forces Foundation), Tüpraş, and Koç Holding.

The company provides five integrated maritime services: ship management and fleet operations, brokerage (vessel finding for crude oil and petroleum product transportation), agency services (strait and general agency since May 2008), terminal vetting at Tüpraş's İzmit and İzmir refineries, and towage services (operating 13 tugboats performing approximately 3,600 ship maneuvers annually). All services are contracted primarily through direct enterprise relationships with parent company Tüpraş, Turkey's largest industrial company, with revenue generated through managed-services fees, transaction fees, and professional services fees. The underlying technology platform includes methanol-ready vessel engines for low-carbon shipping, scrubber systems for emissions reduction, Ballast Water Treatment Systems (BWTS), and digital fleet monitoring infrastructure.

The company employs approximately 800 personnel across ship, terminal, and office operations, with headquarters in İstanbul (Üsküdar) and operational offices in Kocaeli, İzmir, London, and Saudi Arabia. Ditaş is investing in fleet modernization with vessels equipped with methanol-ready infrastructure, including T.FLORYA and two additional 12,000 DWT chemical tankers under construction at RMK Marine with delivery through 2026. The company maintains international classification certifications, Intertanko Council membership, and alignment with SIRE 2.0 and TMSA standards.
