Optimizing Vessel Performance with Comprehensive Main Engine Overhaul

When operating smoothly, it can prolong the life of the engine as well as ensure the safety of the whole ship when sailling on high seas with big waves or bad weather.
To ensure this, it is necessary to have a periodic machine overhaul plan, to improve the machine’s life.

Hai Ha M&S is a leading provider of ship repair services, with extensive experience in main engine overhauls. In this article, we will outline our step-by-step process for overhauling a main engine.
Step 1: Shutdown All Related Systems
The first step is to shut down all related systems, including starting systems, lubrication systems, fuel systems, and exhaust systems.
Step 2: Inspect Shaft Condition
The next step is to inspect the condition of the main engine’s shaft. The inspection involves opening the cover and conducting a thorough check to ensure there is no damage or wear.
Step 3: Remove Cylinder Head
The cylinder head needs to be removed to access the engine’s internal components. Our experienced technicians will disconnect all connections and observe the area carefully before lifting to ensure absolute safety. After the cylinder head is removed, we conduct cleaning and inspection.
Step 4: Remove Piston and Connecting Rod
We then remove the piston and connecting rod for cleaning and inspection. This process involves cleaning the piston, measuring and inspecting the oil scraper ring groove for wear, and replacing all piston rings.
Step 5: Crown Piston, Liner, and Gudgeon Pin
In this step, we clean, measure and replace the crown piston, liner, gudgeon pin and bushing if necessary.
Step 6: Install New Liner
We replace the liner after cleaning and measuring the bore diameter. Our technicians take accurate measurements and replace the O-ring before conducting a water test to check the liner’s tightness.
Step 7: Reassemble
Once all the parts have been cleaned, measured, and replaced, we reassemble the engine with precision, ensuring all connections and components are properly installed.
