About Us

Experience from the field, shaped by engineering.

Alyans Mühendislik Gemi Makina Sanayi ve Ticaret Ltd. Şti. (Alyans Engineering) was founded in May 2003 by Metin Yazıcıoğlu, Marine Engineer, and Şükrü Yahya Olğun, Naval Architecture & Marine Engineer. The founding team's combined experience of more than 25 years in shipbuilding and ship repair remains the foundation of the technical competence the company has built since.

With our expert engineering team, we serve Turkish- and foreign-flagged vessels at home and abroad across a broad technical range — from ship and yacht machinery maintenance and repair to precision machining, portable on-site machining and laser alignment. We never compromise on delivering our projects on time and in full.
