Unit and engine overhauls
Pistons, liners, rings and exhaust valves, with liner wear and crankshaft deflection measured and recorded.
Peak-performance overhauls, targeted troubleshooting and specialty work, including stern tube leak sealing with ABCON additives, deployed the same day when needed.
Oil escaping to sea through the aft seal, or seawater getting into the stern tube oil, both need action before they become a pollution case or a bearing failure. ABCON PTFE-based additives can often stop the leak on board, so the vessel keeps trading until its scheduled dry-dock.
Additives are a temporary measure. They buy time; worn seals and grooved liners are renewed in dry dock. In US waters, oil-to-sea interfaces are expected to use environmentally acceptable lubricants (EALs), so tell us which oil is in the system.
In our Tuzla workshop, in dry dock or on board, depending on the machinery and the vessel's schedule.
Pistons, liners, rings and exhaust valves, with liner wear and crankshaft deflection measured and recorded.
Top and major overhauls at the running hours set by the maker's maintenance schedule.
Brakes, gears, bearings and drums overhauled in the workshop or on deck, with a brake test after the work.
Propeller polishing, thruster seals and bearings, and stern gear work during the dock stay.
Vibration, high temperatures and falling performance traced to the cause before parts are ordered.
DEVA® maintenance-free bearings and Bondura expandable pins for joints that keep wearing out.
Photographs taken by our own engineers on recent jobs in the Tuzla and Yalova shipyard regions.
One engineer for a fault-finding visit. A full team on site within a week for a dry-dock or a retrofit. Whatever the size, every job runs the same way.
Written down and agreed before the work starts.
Findings recorded, not assumed.
Progress to the owner every day.
Documentation handed over with the job.
An overhaul or a breakdown is quoted per project. Fleets of three or more vessels can add quarterly preventive maintenance inspections and priority 24/7 emergency response.
The more of this we have, the fewer questions we need to ask before we can price the work. Send what you have; we'll ask for the rest.

Often, yes. ABCON PTFE-based additives can stop oil leaks and water ingress so the vessel keeps sailing until its scheduled dry-dock. It is a temporary measure: the permanent repair is planned for the dock.
The same day when needed, on board, at Turkish ports or in transit through the region.
Yes. Tell us whether the system runs on mineral oil or an environmentally acceptable lubricant (EAL), so the treatment is matched to the oil.
Main engines and generator engines, mooring and towing winches, propellers and thrusters, with troubleshooting before and after.
In our workshop in Tuzla, in dry dock in the Tuzla and Yalova shipyards, or on board.
The same team covers agency, engineering and parts, so one contact handles the whole job.
Send the machinery details and the symptoms. We'll come back within one working day, and the same day for a stern tube leak.
