 Why Aluminum Hydraulic Oil Coolers Matter on Ships

Hydraulic systems generate a significant amount of heat, especially in maritime environments where cranes operate intensively under heavy loads. The hydraulic oil cooler, often called a heat exchanger, plays a vital role in maintaining oil temperature within optimal limits. Overheating not only reduces the efficiency of hydraulic operations but can also lead to costly equipment damage.

Common failure modes of marine oil coolers include:

• Internal corrosion due to seawater exposure
• Tube leaks or cracked headers
• Aluminum weld fatigue from vibrations
• Blockage of fins reducing thermal efficiency

That’s why routine inspection and timely repair are critical to ensuring reliable operation and avoiding operational downtime.

 Step-by-Step Repair Process by Bacviet Shiprepair Company

Bacviet Shiprepair Company offers a comprehensive service process with both on-site and in-shop solutions. Here's how we handled one of our recent hydraulic cooler repair jobs for a cargo vessel:

1.  Onboard Dismantling

Our technical team boarded the vessel while it was docked and carefully dismantled the damaged hydraulic oil cooler unit from the crane’s hydraulic system.

 This step involved:

• Tagging and isolating hydraulic connections
• Removing mounting brackets and support hardware
• Transporting the unit to our repair facility

2.  Leak Detection & Pressure Testing

 Once in the workshop, the cooler underwent initial pressure testing to identify exact leakage points and assess the structural integrity of aluminum fins, tubes, and end covers.

3. To Aluminum Welding and Structural Restoration

Based on the test results, we identified multiple micro-leaks along the seam of the header tank and at the junction of the core and side panel. Our welders, using argon TIG welding, restored these areas using marine-grade aluminum filler.

4.  Final Cleaning & Pressure Testing

After welding, the unit was thoroughly cleaned with high-pressure water jets and re-tested at full working pressure to confirm zero leakage before reinstallation.
