MAIN ENGINE OVERHAUL

WELCOME TO SEAFIX – MARINE REPAIR SERVICES IN VIET NAM!

Main engine is the heart of the vessel, which provide all the power for the vessel, even the propulsion of propeller moving the ship. Main engine is important, it is necessary to understand the main engine operation, as well as how to operate professionally, increase the efficiency and partly increase the life of main engine and relevant equipment. To overhaul, recondition, compulsory that the worker shall be understand the main engine and what have to do to complete the job.

The following is a look into the overhaul of a MAN B&W 6S50MC main engine. The overhaul was performed by SEAFIX. The objective of the overhaul was to make sure that all the cylinder units, once inspected and overhauled, would perform another trouble frees period of about 20,000 running hours.  Their engineers talk with the Chief Engineer and the vessel’s owner to understand their needs, how their engines are operated and then makes recommendations. This is all done without jeopardizing the engine performance and reliability, and it is a solution that is cost conscious and prepares the engine for future reliable operation.

With the importance of such a main engine, any incident with it will lead to a very serious consequence. Therefore, it is necessary to periodically survey the main engine, while time The space of each ship is limited, especially container ships.

SEAFIX MRS, with our experience and skill, has disassembled and inspection many main engines.

The basic steps of main engine overhaul:

• The repair process begins with dismantling the engine. This step entails taking out major components such as the cylinder head, crankcase, and pistons. After they are removed, each component is carefully inspected for any signs of wear or damage. Parts found damaged or excessively worn are replaced with new ones.
• Subsequently, the engine undergoes a thorough cleaning to eliminate any accumulated dirt, debris, or other impurities. This cleaning process is often carried out with specialized tools such as highpressure hoses and ultrasonic cleaning devices.
• Once the engine is both cleaned and inspected, it is put back together. This reassembly may involve incorporating new or refurbished parts as required. Finally, the engine undergoes testing to confirm that it operates correctly and aligns with all the specifications set by the manufacturer.

What causes main engine overhaul:

Repair may be needed due to poor performance. If your engine isn’t performing optimally, an overhaul can help identify and correct problems, which may include replacing or upgrading parts.

Indicators of poor performance necessitating an overhaul include:

Diminished power: Less power output can signal wear or damage in engine components, which an overhaul can address.

Decreased fuel efficiency: Increased fuel consumption may indicate inefficiency, diagnosable and repairable through an overhaul.

Unusual engine noises: Knocking or pinging sounds suggest internal component issues, which can be identified and resolved through an overhaul.

Excessive smoke: High levels of smoke from the engine point to internal problems, correctable with an overhaul.

Damage is another common cause that requires repair. Whether due to an accident or the use of low-quality fuel, such damage often requires repair or replacement of the affected engine components.

Specific damage types that might lead to an overhaul include:

Physical damage: Accidents or other physical impacts can necessitate engine repairs or replacements, with an overhaul assessing and addressing the damage.

Water damage: Exposure to water, like in floods, may require engine repair or replacement. An overhaul can determine the damage’s extent and needed repairs.

Corrosion: Corroded engines may need repair or replacement, with an overhaul revealing the severity and required fixes.

Wear from low-quality fuel: Using substandard fuel can cause additional engine wear and damage, which an overhaul can help identify and rectify.

Neglecting maintenance is also a major reason for repair. Regular maintenance, such as changing the oil, adhering to service intervals, and fixing problems promptly, is critical to the health and longevity of your engine. Failure to properly maintain a engine can lead to various problems.
