🎯 Your Global Marine Parts Partner in Turkey

Seaway Ship Services has been supplying marine spare parts from Turkey since 1989, leveraging our strategic position at the crossroads of Europe, Asia, the Black Sea and the Mediterranean to deliver parts faster and more cost-effectively than any distant supplier.

Our parts division maintains comprehensive stock in two warehouses — Istanbul (Tuzla) and Yalova — covering fast-moving consumables, critical engine components, safety equipment, deck machinery parts and navigation consumables. For non-stocked items, our global sourcing network reaches OEM factories, authorised distributors and specialist dealers across Europe, Asia and the Americas.

Whether your vessel needs a single gasket urgently at Piraeus, a full set of cylinder liners for a scheduled overhaul at Constanta, or a second-hand turbocharger for an older engine at Aqaba — we find it, verify it, pack it and ship it. Our team handles all export documentation, customs clearance and courier tracking.
