Sefine Shipyard Turkey: Ship Repair, New Builds & Conversions

Aframax-size tankers, hybrid ferries, methanol-ready vessels—few shipyards in the region can handle all three under one roof. Sefine Shipyard Turkey does.

Based in Yalova, Sefine Shipyard is one of Turkey’s most capable yards for newbuilding, ship repair, conversion, and heavy steel fabrication. Its dock capacity, environmental retrofit expertise, and experience with complex turnkey projects make it a practical choice for owners operating in Europe, the Mediterranean, and beyond.

About Sefine Shipyard Turkey

Sefine Shipyard operates in Altınova, Yalova—Turkey’s main hub for large commercial shipyards. The yard is known for handling technically demanding projects rather than volume production, with a focus on ferries, offshore vessels, cargo ships, and large-scale repair work.

What sets Sefine apart is dock flexibility. The shipyard can repair vessels up to 90,000 DWT in its Post‑Panamax graving dock and up to 120,000 DWT in its Aframax floating dock. Together with additional lifting capacity, this allows simultaneous dry-docking of large vessels—something that reduces waiting time during busy repair seasons.

Newbuilding Know‑How That Goes Beyond Standard Designs

Sefine Shipyard builds a wide range of vessels, often tailored to specific operational routes and regulatory regimes:

• General cargo vessels
• Double‑ended car and passenger ferries
• Offshore support vessels
• Search and rescue boats
• AHTs and tugboats
• Live fish carriers

In recent projects, the yard has increasingly focused on hybrid, LNG‑ready, and methanol‑ready designs, aligning with tightening European emission rules and operator demand for fuel flexibility.

Activities Of Sefine Shipyard Turkey

NEW BUILDING

Sefine Shipyard has delivered vessels to operators in Northern Europe, the Baltic, and the Mediterranean. The yard is particularly well known for turnkey ferry projects, where hull construction, outfitting, testing, and delivery are handled under a single contract.

Today, newbuilding activity continues with:

• Hybrid and battery‑assisted ferries
• Offshore support vessels with low‑emission propulsion
• Specialized cargo vessels, including live fish carriers

Ship Repair

Ship repair remains one of Sefine’s strongest segments. The yard operates a large Aframax floating dock measuring approximately 282 m × 47 m with a 40,000‑ton lifting capacity, one of the largest in Turkey.

This infrastructure allows Sefine to handle:

• Aframax tankers
• Mini‑cape bulk carriers
• Container vessels up to around 10,000 TEU
• Gas carriers and Ro‑Ro vessels
• Cruise ships and passenger vessels

Maximum docking capacity: 120,000 DWT

Full‑Spectrum Ship Repair

Combined with its 90,000 DWT graving dock and additional heavy‑lift infrastructure, Sefine can manage parallel repair campaigns on multiple large vessels. Typical scopes include steel renewal, propulsion work, BWTS and scrubber retrofits, and life‑extension projects.

Insider tip: booking slots well ahead of peak survey seasons (spring and autumn) significantly reduces idle time and cost exposure.
