Sefine Shipyard

Sefine Shipyard, also known as Sefine Tersanesi, is a Turkish shipbuilding and marine-services facility located in the shipyards area of Altınova in Yalova Province, near the Osman Gazi Bridge. The yard is owned by Sefine Denizcilik Tersanecilik Turizm A.Ş., a company within Koloğlu Holding. It was established in 2005, while shipbuilding operations began in 2008 and construction of a dry dock followed in 2009. The facility combines new-build ship construction with repair, maintenance, conversion, and industrial steel fabrication. Its reported site area is approximately 140,000 square metres and includes a covered steel-sheet processing workshop of almost 11,000 square metres, a 160-by-60-metre shipway, a 240-by-42-metre dry dock, a 200-metre quay, and a 282-by-49-metre floating dock. The yard has stated steel-processing capacity of about 40,000 tonnes per year. Its core workforce has been described as approximately 370 personnel, including around 80 engineers, while the broader workforce can vary from roughly 1,500 to more than 2,000 depending on project activity. Sefine builds a diverse range of vessels rather than focusing on one narrow ship type. Its documented output includes tugboats, fireboats, salvage tugs, passenger and vehicle ferries, icebreakers, liquefied petroleum gas carriers, well-boats for aquaculture, and hybrid-electric ferries. The yard has also constructed vessels for Turkish public-sector maritime authorities and exported ships to customers in Europe. This mix gives the company exposure to public-service shipping, short-sea and ro-ro transport, fisheries and aquaculture logistics, and specialized marine operations. A notable domestic project was the ERV Nene Hatun, delivered in 2015 to Turkey's Directorate General of Coastal Safety as the country's first emergency response vessel. The yard has also built salvage tugs for the same authority. Its export program expanded through ferry projects for Estonia and Norway, including vessels ordered for TS Laevad and Fjord1. Sefine additionally produced the hybrid-electric MF Bastø Electric for Norway, a large ferry designed for zero-emission operation in service, and participated in further hybrid ferry work. Beyond new construction, the shipyard undertakes dry-dock and floating-dock repair work, primarily for domestic vessels, and converts dry-cargo ships into cement carriers. It also fabricates steel components for major infrastructure projects. Its documented industrial work has included parts associated with the Osman Gazi Bridge and the new Istanbul Airport. These capabilities position Sefine as an integrated shipyard serving both maritime and heavy-steel construction markets. By the early 2020s, Sefine had built at least 29 ships over the preceding decade according to the referenced encyclopedia account. Its projects demonstrate a development from a Turkish yard serving domestic and specialized requirements into an exporter capable of delivering ferries, aquaculture vessels, emergency-response ships, and low-emission propulsion platforms for international operators. Publicly available reference material does not establish a separate stock-market listing, a founder, or a current named executive leadership team.

Sefine Shipyard was established in 2005 in Altınova, Yalova Province, one of Turkey's important shipbuilding areas. The business operates through Sefine Denizcilik Tersanecilik Turizm A.Ş. and is associated with Koloğlu Holding. Although the company was established in 2005, shipbuilding at the site began in 2008. In 2009, the yard began constructing a dry dock, expanding its ability to undertake vessel maintenance as well as new construction. The completed facility developed into a multi-purpose shipbuilding and marine-services complex. It covers about 140,000 square metres and includes a covered steel-processing workshop of nearly 11,000 square metres. Its major marine infrastructure comprises a 160-by-60-metre shipway, a 240-by-42-metre dry dock, a 200-metre quay, and a 282-by-49-metre floating dock. The yard is reported to be capable of processing approximately 40,000 tonnes of steel plate annually. Staffing varies according to the workload, with a core group of about 370 personnel, including around 80 engineers, and a project workforce that can reach between 1,500 and more than 2,000 people. The yard's early and continuing work has covered a broad selection of vessels. Sefine has built tugboats, fireboats, salvage tugs, passenger and car ferries, icebreakers, LPG carriers, and well-boats. It has also supplied vessels to Turkey's Directorate General of Coastal Safety, including salvage tugs and the ERV Nene Hatun. Delivered in 2015, the emergency response vessel was identified in the source material as Turkey's first vessel of that type. Sefine's business became increasingly international through ferry and specialized-vessel exports. It built passenger and vehicle ferries for Estonia, including vessels associated with TS Laevad, and supplied several ferries to Norway's Fjord1. The Norwegian projects included MF Sildafjord, MF Florøy, and MF Hillefjord. The yard also entered the aquaculture-vessel market with well-boats such as Aqua Skye for DESS Aquaculture Shipping and Gåsø Høvding for Frøy. Hybrid and lower-emission ferry construction became another visible part of the yard's portfolio. Sefine delivered MF Bastø Electric to Bastø Fosen in February 2021. The approximately 145-metre ferry uses a 4.3 MW hybrid-electric system and was described as a zero-emission vessel in operation. The yard subsequently launched the smaller hybrid-electric MF Svelvik for the same operator. In 2021, it also received an order from Italy's Caronte & Tourist for an LNG-hybrid ro-pax ferry designed to comply with SOLAS requirements. Ship repair and conversion remain important complementary activities. Sefine uses its dry and floating docks for maintenance and repair, with the referenced account stating that this work is mainly performed for domestic ships. The yard also converts dry-cargo vessels into cement carriers. In addition to marine work, it fabricates steel construction components for infrastructure. Its documented projects include steel parts connected with the Osman Gazi Bridge and the new Istanbul Airport. The reference material states that Sefine built 29 ships during the preceding ten-year period. Taken together, the facility's history shows a progression from a newly established Turkish yard into an integrated contractor serving government maritime agencies, European ferry operators, aquaculture logistics companies, and infrastructure projects. Available reference material does not provide a complete chronology of every vessel, a verified current management roster, or detailed corporate financial information.
