Ortech Marine Maintenance S.A is the engineering partner that integrates world-class marine technology into vessels worldwide — from our EuroAsian hub at the crossroads of three continents, with operational reach into both the Tuzla and Yalova shipyard regions. Founded and led by senior marine engineers, we exist to take the weight of repair, maintenance and compliance off the shipowner.
Ships don't run on schedules — they run on the people who keep them running. Ortech Marine exists to take the weight of repair, maintenance and compliance off the shipowner, so the ship can do what a ship is supposed to do. Stay at sea.
We are headquartered near the main shipyard area of Tuzla, Istanbul — twenty minutes from Sabiha Gökçen International Airport — with full operational reach across the Sea of Marmara into the Altınova shipyards of Yalova. Whatever flag your vessel flies, whether it docks at Tuzla or Yalova, we can be on board within hours.
Our work has grown from a single engineering practice into a portfolio of formal partnerships with manufacturers across Europe — specifying, integrating, commissioning and servicing the systems that owners trust their vessels to. We don't resell. We engineer.
Our commitment to the sector reaches beyond our own vessels. Ortech Marine is a founder company of GOSDER — Gemi Onarım Sanayicileri Derneği, Türkiye's Ship Repair Industry Association, and holds a board seat there today. Setting the standards for the industry we serve, not only working within it.
Alongside the engineering, Ortech operates as a full ship's agent in the Tuzla region — handling port-state liaison, customs clearance, yard selection and contract negotiation on the owner's behalf. The same team that scopes your repair also clears your parts through customs and negotiates your yard contract. One contact. Every link of the chain.

Every project at Ortech Marine is owned by a chief marine engineer with over three decades of experience at sea and in the world's leading shipyards. There is no layer of account-managers between you and the engineer who scopes the work. The person who answers your enquiry is the person who'll be on board the vessel.
Over thirty years of sea time and shipyard experience across propulsion, automation and electronics. Leads every Ortech Marine engagement personally — from first survey to final handover. Board Chairman of GOSDER, Türkiye's Ship Repair Industry Association.
Three commitments shape every project we take on — from a same-day stop-leak deployment to a multi-week dry-dock retrofit.
Every engagement is owned by a marine engineer with sea time. We solve problems, we don't just specify products. Decisions are made from the engine room outward, not the catalogue inward.
We work for the shipowner, not the yard. Single point of accountability, daily reporting, transparent scoping — so you know exactly where your vessel stands at every moment.
Operating from the intersection of three continents lets us combine top-tier quality with prices that materially reduce repair expenses. The geography is the saving.
Our offices and workshops sit alongside the major shipyards of Tuzla — twenty minutes from Sabiha Gökçen International Airport — with full operational reach across the Sea of Marmara into Yalova's Altınova shipyard cluster. Two of Türkiye's principal shipyard regions, both within hours of mobilisation.
Whether you're planning a dry-dock, scoping a retrofit, or facing an unscheduled breakdown — share a few details and we'll come back with a named engineer and a path forward within one working day.
