Project Overview

• Client: Container vessel Greenville
• Location: Nam Dinh Vu Container Terminal, Hai Phong, Vietnam
• Main Engine: WinGD 6X82-2.0
• Scope of Work: Removal of old cylinder liner and installation of new liner supplied by the vessel
• Duration: Completed within scheduled port stay
• Service Provider: Bacviet Shiprepair Company.

‍ Onboard Service – Mobilization and Preparation

Our experienced team of marine engineers and technicians was promptly dispatched to the vessel upon request. After clearance with port authorities and ship’s management, we mobilized with all necessary tools, safety gear, and lifting equipment.

Upon boarding the vessel, the following preparatory steps were taken:

• Comprehensive safety briefing with the crew
• Review of engine layout and inspection of the designated unit
• Setting up lifting points and protection for surrounding engine components.
• Verifying that all parts and replacement liner were available onboard.

To Disassembly and Removal of Old Cylinder Liner

Our technicians began by carefully dismantling all components around the affected cylinder unit:

• Removal of cylinder head, fuel injection system, cooling and lubricating connections
• Disconnection of hydraulic tightening tools and sensors
• Extraction of piston and connecting rod assembly

Once all surrounding parts were safely removed, the old cylinder liner was extracted using a combination of chain blocks and hydraulic jacks. Special attention was paid to ensure no damage to the engine block or sealing surfaces.

 Installation of New Cylinder Liner

The new cylinder liner, supplied by the vessel, was inspected and cleaned thoroughly prior to installation. We then proceeded with:

• Lowering the new liner into position using custom-made lifting tools
• Checking alignment, verticality, and seating of the liner
• Performing visual and dimensional inspection of liner fitment
• Installing new sealing rings and lubrication connections

All installation steps were performed in full accordance with WinGD OEM procedures and class requirements.

Final Assembly and System Integrity Testing

After the new liner was installed, our team reassembled all components, including:

• Re-installation of piston, connecting rod, and cylinder head
• Re-connection of all cooling, lubrication, and fuel systems
• Calibration of fuel injectors and tightening of cylinder cover bolts using hydraulic tools

Once mechanical reassembly was complete, we conducted the following tests:

• Leak test of cooling and lubricating circuits
• Crankshaft rotation check for smooth movement
• Bore scoping and visual inspection of the liner and piston fit
• Sensor verification and signal testing to the control system

No-Load Engine Testing

As a final step, the main engine was cranked and started in no-load (idling) condition, in the presence of the ship’s chief engineer and superintendent.

• Engine start-up was smooth and stable
• No abnormal vibration or noise detected
• Temperature and pressure readings remained within normal range
• All safety trips and interlocks tested successfully

The cylinder unit was observed over a short operational run to ensure full system integrity. After successful verification, the engine was handed over to the ship’s technical team for operational use.
