What Istanbul Shipyard does

Istanbul Shipyard (İstanbul Denizcilik A.Ş.) is a Turkish shipbuilding and ship repair company established in 2003 and headquartered in Tuzla, Istanbul. Operating as a wholly-owned subsidiary of SNR Holding, the shipyard serves government defense agencies, coast guards, and commercial shipping companies with new vessel construction, repair and maintenance, conversion, and design services. The facility spans 51,000 m² with 14,400 m² of enclosed workshop space, 6 building berths, 3 piers, and 2 floating docks providing 11,000 tons of combined lifting capacity. Headcount is reported in the 11-50 range, and the asset base supports simultaneous work on up to 13-14 vessels and an annual steel throughput of 25,500 tons.

The product portfolio spans naval and commercial segments. Naval offerings include four in-house fast patrol boat designs (SNR-15, SNR-17, SNR-24, SNR-42), the MOSHIP submarine rescue mother ship (90.8m) certified to both NATO NSRS and US SRDRS standards, the SNR-KURYED rescue and towing ship, hydrographic survey vessels, and the SAR35 modernization program for the Turkish Coast Guard. Commercial offerings include oil and chemical tankers, stainless steel tankers, offshore structures, ROV support ships, and the SNR-SEISMIC seismic research vessel with diesel-electric propulsion and azipull thrusters. Underpinning the portfolio is an in-house design and engineering office staffed by naval architects and 10+ year-experienced designers, alongside a propeller research and development branch established in 2011 focused on fixed-pitch and controllable pitch propeller (CPP) design and production — positioning the shipyard as one of the first Turkish groups with a sole CPP focus. Operations are governed by ISO 9001, ISO 14001, ISO 45001, and OHSAS 18001 certifications, IACS membership, and class society approvals from DNV, GL, ABS, and Bureau Veritas.

Revenue is generated entirely through project-based B2B contracts with no publicly disclosed pricing. The most visible customers are the Turkish Ministry of Defence (naval vessels, including submarine rescue ships and fast patrol craft), the Turkish Coast Guard Command (SAR35 modernization), and a portfolio of international marine transporters and oil companies served through newbuild, repair, drydocking, and conversion services. Recent strategic wins include an STM-led contract for the first Turkish National Fast Attack Craft (keel laid October 27, 2025) and shipbuilding cooperation agreements signed with Malaysia in December 2019. Distribution occurs exclusively through direct enterprise sales, with demand generation supported by a multilingual corporate website, YouTube and Vimeo video content of vessel sea trials, press coverage, and participation in international defense exhibitions.
