Major Overhaul of Ship’s Air Conditioning System – Condenser & Compressor Renewal, Leak Test & Gas Charging by Qualships Australia
At Qualships PTY Australia, we recently carried out a comprehensive overhaul of a ship’s air conditioning system, ensuring peak performance and reliability for critical onboard climate control. Our expert marine technicians executed a complete service plan, including condenser overhaul, compressor renewal, system vacuuming, refrigerant gas charging, and a thorough leak test. Scope of Work: 1. Condenser Overhaul: The ship’s AC condenser unit was dismantled, inspected for corrosion, cleaned thoroughly, and pressure-tested to confirm structural integrity. Necessary seals and gaskets were replaced, ensuring efficient heat exchange and preventing future failures. 2. Compressor Renewal: The aging AC compressor was removed and replaced with a new, high-performance marine-grade compressor. All connections were aligned and torqued as per OEM specifications, ensuring proper alignment and vibration-free operation. 3. System Vacuuming & Dehydration: Using our state-of-the-art vacuum pump setup, the entire refrigeration circuit was evacuated to remove moisture and air pockets. This process is critical in preventing internal corrosion and ensuring the longevity of AC components. 4. Refrigerant Gas Charging: The system was charged with R-134a refrigerant as per the correct volume and pressure parameters. We ensured the system pressure matched operating specs, securing optimal cooling performance across all cabins and control rooms. 5. Leak Test & Final Inspection: A comprehensive leak test using nitrogen and soap solution was conducted, followed by an electronic leak detector scan. No leaks were detected, and the system was declared operationally sound. ⸻ This major AC system overhaul was completed successfully with zero downtime and no refrigerant loss, meeting Class and Owner satisfaction.

McGregor GLB3024.5 Ships crane major Cabin fabrication and repairs
Crane Cabin Structural Repair & Welding Renewal by Qualships – Trusted Marine Workshop in Australia During routine operations, local port authorities and stevedores discovered major corrosion beneath the crane cabin carpet, including severely deteriorated floor plating, and corroded window frames. This posed a significant safety hazard within the crane operating area. Qualships PTY Australia was engaged to carry out a complete structural repair, and our class-approved welding team, including DNV-certified welders, took immediate action. Our expert fabrication crew cut and installed new steel floor plates, following original OEM dimensions to ensure precise installation of the new crane cabin flooring system. We also repaired and renewed corroded window frames, restoring them to full strength using approved marine-grade welding procedures. As part of our safety upgrade, new safety hoops were fabricated and installed by the Qualships in-house team, enhancing protection and compliance within the crane cabin structure. This project highlights Qualships’ commitment to delivering marine crane structural repairs to the highest industry standards, with rapid turnaround and full class compliance. Operating across NSW, QLD, VIC, and WA, Qualships is your trusted partner for: • Certified ship welding repairs • Structural renewals for crane cabins • DNV-approved steelwork • Precision marine fabrication and modifications

Qualships Successfully Completes Critical EGCS Overboard Pipe Renewal
Qualships Pty Ltd, renowned for its commitment to maritime quality and safety, has successfully completed a critical Exhaust Gas Cleaning System (EGCS) overboard pipe and spool piece renewal on an oil tanker. The maintenance operation took place in Geelong, Victoria, Australia. The original EGCS overboard stub piece and associated pipeline were severely corroded, compromising structural integrity and safety, resulting in minor leakage and non-compliance with classification requirements. Immediate action was essential to restore the vessel's operational readiness and ensure adherence to maritime safety regulations. Qualships undertook comprehensive safety and risk assessments, coordinated necessary approvals, and executed precise fabrication and installation of new pipeline sections. Utilizing advanced welding techniques and corrosion protection systems, including a Corrocoat coating exceeding 3000 microns thickness, Qualships guaranteed enhanced durability against harsh marine environments. Following rigorous Magnetic Particle Testing (MPI), the installation was declared leak-free and compliant with all class standards. Qualships continues to set industry benchmarks in marine quality assurance, exemplifying dedication to safety, efficiency, and environmental responsibility.
