Since 2001, SEFT has carried out the design of many different types of ships. Following its new vision set in 2007, it has also demonstrated its capability to succeed in military ship design. SEFT’s main special designs include: Police Boats for the Romanian Border Police, the Submarine Rescue Mother Ship (MOSHIP) and Rescue & Towing Ship (KURYED), the Fleet Replenishment Combat Support Ship (DİMDEG), the Unmanned Surface Vehicle (MARLIN) for Turkish Navy, a Seismic Research Vessel for the General Directorate of Mineral Research and Exploration, a Fleet Replenishment Tanker and a Customs Patrol Boat for the Royal Thai Navy. SEFT continues its activities at Teknopark Istanbul with a team of 100 people in an area of approximately 1,000 m².
Developed to provide the Turkish Navy with state-of-the-art submarine rescue capabilities, TCG Alemdar stands out as one of the most capable submarine intervention vessels in the world. The world’s first ship compatible with both NSRS and SRDRS systems. The world’s first platform capable of ventilation at 620 meters depth. The world’s first submarine rescue ship with a four-point light mooring system. Türkiye’s first diving vessel equipped with a Personnel Transfer Capsule (PTK). The first Turkish ship with military-standard electric propulsion. All of these capabilities are underpinned by SEFT’s comprehensive design, modeling, analysis, and production-focused engineering approach, achieved with 100% Turkish engineering.
These two platforms expand the Turkish Navy’s multi-role support capabilities, having been designed and optimized with SEFT’s engineering expertise to meet operational mission needs. Integrated systems supporting submarine rescue, salvage operations, firefighting, underwater repair and maintenance, and offshore towing. Equipped to provide life support and personnel rescue up to 600 meters in cases where submarines cannot surface. Features DP-1 Dynamic Positioning capability with two aft tunnel thrusters, one elevator-type thruster, and one bow thruster.
SEFT Engineering has contributed to the modernization of the Coast Guard Command’s SAR33-class boats by: Enhancing high-speed maneuverability. Integrating a new twin-engine propulsion system (replacing the original three-engine setup). Upgrading electronic and communication systems. These improvements deliver direct engineering solutions to increase the operational effectiveness of the Coast Guard.
ORUÇ REİS is a scientific and strategic research vessel distinguished by its advanced capabilities. The first ship in the world to combine seismic, hydrographic, and oceanographic research capabilities in a single platform. Türkiye’s first indigenous platform capable of 2D/3D seismic research. The most capable scientific research vessel in Türkiye, equipped with ROV-supported survey systems.
SEFT Engineering has contributed to the mid-life modernization of the Barbaros-class frigates, supporting: Integration of locally developed weapon systems. Combat management system integration. Structural platform modifications. Project enhanced SEFT’s expertise in warship engineering. 3D laser scanning was employed to ensure uninterrupted operational availability during deployments while advancing engineering processes. Provided engineering services for integration of indigenous combat systems. Delivered customized engineering solutions tailored to Navy requirements. Represented one of Türkiye’s most comprehensive combat management system integration efforts.
Built to provide logistical support for Turkish Navy operations on the high seas and in distant waters, SEFT delivered the ship’s design and engineering services. With SEFT’s engineering design, TCG DERYA is: The highest-capacity indigenous support platform capable of simultaneously replenishing multiple ships with fuel, water, munitions, and personnel. Equipped for helicopter operations, littoral support missions, and serving as a mobile base during crises. The most modular military logistics vessel capable of functioning as a command and control ship when needed. With this project, SEFT became the first local engineering firm to design the system architecture for large-tonnage military logistics platforms.
The MARLIN project is a flagship initiative in Türkiye’s drive for indigenous unmanned naval systems. The first indigenous Unmanned Surface Vehicle to enter service with the Turkish Navy. The first Unmanned Surface Vehicle in the world equipped with electronic warfare systems. SEFT was responsible for the complete technical modeling process, from system architecture to mission profile optimization.
In this project, SEFT delivers modern solutions to enhance maritime security through advanced sonar systems and platforms designed for unmanned vehicle operations. Türkiye’s first mine countermeasures vessel designed around indigenous sonar systems. The first low-magnetic-signature mine countermeasures vessel in the world capable of conducting operations with unmanned naval systems.
SEFT contributed to the design of these platforms to meet modern technical requirements for long-range surveillance, patrol, and border security missions, offering: The longest-range indigenous patrol vessel class developed for maritime border security.
IFF system integration has been provided to all platforms in the Turkish Naval Forces inventory.
Engineering support was provided during the Kınalıada Integration process, which was the first platform where the ATMACA System was integrated.
Engineering support was provided for the integration of ASELSAN GÖKDENİZ weapon system.
Engineering support was provided during the STAMP-2 Integration process to GABYA Class Frigates.
We are providing engineering services for the Multi Purpose Mission Ship (MPMS) project to be built at Desan Shipyard for the Malaysian Coast Guard. This modern vessel will strengthen Malaysia’s maritime security with capabilities for patrol, search and rescue, and humanitarian missions. We deliver comprehensive solutions in design, system integration, and structural engineering, adding value to Türkiye’s defense industry through global collaborations.
