ROLLS ROYCE WINDLASS /WINCHES HYDRAULIC TROUBLE RECTIFICATION
Qualships Completes Critical Hydraulic Repair at Port Botany Port Botany, Australia — 17 May 2025 In a successful display of marine engineering expertise, Qualships Pty Ltd has completed the comprehensive rectification of an inoperative starboard windlass/mooring winch hydraulic system aboard a major container vessel. The intervention took place at Port Botany under instruction from Ship Owner, ensuring minimal downtime and restoring critical anchoring capabilities to the vessel. Upon boarding and conducting initial diagnostics, the Qualships engineering team identified a complete failure in the hydraulic system. Pressure readings taken after the control block and before the hydraulic motor indicated zero pressure—pinpointing a fault within the control block as the root cause. The control block, comprising three sections, was systematically dismantled and off-landed along with associated hydraulic piping. The blocks were cleaned, disassembled, and thoroughly inspected at the shore facility. A major issue was identified in the pilot assembly cartridge valve, where a broken washer and debris had caused internal flow bypass, rendering the windlass inoperative. Key remedial actions included: Renewal of all seals, O-rings, and backup rings. Replacement of all nuts and bolts. Polishing of cartridge valve and slide surfaces. Removal and rethreading of broken studs from Block C. Post-repair, the control blocks underwent bench testing and were reinstated onboard. Final system trials confirmed full restoration of the starboard windlass/mooring winch, now operating to standard. Recommendations: Qualships advises regular inspection of hydraulic components, timely flushing, and filter replacement schedules to avoid similar faults in future. This successful operation reinforces Qualships’ commitment to delivering high-quality marine engineering support with minimal operational disruption.

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.
