Windlass Services at Quy Nhon Port – Windlass Block Valves Overhaul by VietNam Shiprepair
Is your Capesize bulk carrier experiencing hydraulic oil leakage from the windlass block valves at Quy Nhon Port? VietNam Shiprepair provides professional Windlass Services and Marine Services, specializing in the overhaul of windlass block valves to eliminate oil pollution risks and ensure full compliance with PSC-Vietnam regulations. We recently completed the maintenance of the windlass block valves on a Capesize bulk carrier at Quy Nhon Port – a key central port in South Central Vietnam – under the supervision of CCS Class. The work involved disassembling the valve assembly and replacing all components that failed to meet technical requirements, restoring leak-free operation and preventing further environmental violations.
All repairs comply with IACS and IMO standards—learn more at IACS Standards. Our Marine Services are available at Quy Nhon Port and across Vietnam, including Ho Chi Minh Port and Anchorage, Hai Phong Port, and Phu My Port – Vung Tau Anchorage, with full capability to support vessels at any port or anchorage nationwide.

Importance of Windlass Services for Capesize Bulk Carriers
The windlass is a critical system for safe anchoring operations on Capesize bulk carriers. When the block valves develop internal hydraulic oil leakage, the system not only loses efficiency but also creates a direct risk of environmental pollution. Such leakage can lead to PSC deficiencies and potential detentions under Vietnamese regulations. Professional Windlass Services by VietNam Shiprepair restore the integrity of the valve assembly, eliminate oil discharge, and ensure the vessel remains fully compliant with class and port state control requirements.
Professional Windlass Block Valves Overhaul Process under CCS Supervision
VietNam Shiprepair executed the following controlled process for the windlass block valves overhaul at Quy Nhon Port:
- Conducted a detailed inspection of the windlass hydraulic system to identify the source and extent of oil leakage.
- Isolated the system and safely depressurized the hydraulic circuit.
- Completely disassembled the windlass block valve assembly.
- Inspected all internal components for wear, scoring, and sealing failures.
- Replaced all parts that did not meet technical requirements, including seals, O-rings, and worn valve elements with genuine or approved equivalents.
- Thoroughly cleaned and reassembled the valve block with precise torque settings.
- Refilled the system with approved hydraulic oil and performed leak testing under operating pressure.
- Conducted a full functional test of the windlass under CCS Class surveyor supervision to confirm leak-free and reliable operation.
- Prepared detailed documentation and obtained final CCS endorsement for the completed Windlass Services.
This systematic approach eliminated the pollution risk and restored the windlass to full operational reliability.
