Steel Works at Quy Nhon Anchorage – Tank Top Plate Repair by VietNam Shiprepair
Is your Panamax bulk carrier facing a serious tank top puncture in the cargo hold at Quy Nhon Anchorage? VietNam Shiprepair provides professional Steel Works and Marine Services, specializing in urgent tank top plate replacement under full NKK Class supervision. We recently completed the repair of a punctured tank top on a Panamax bulk carrier at Quy Nhon Anchorage – a key central location in South Central Vietnam – after cargo fell back into the hold during loading operations and caused structural damage. The work was executed with NKK-approved steel, certified welding procedures, and qualified welders to restore complete watertight integrity between the cargo hold and ballast tanks, preventing further operational delays and commercial losses for the shipowner, cargo interests, and charterers.
All repairs comply with IACS and IMO standards—learn more at IACS Standards. Our Marine Services are available at Quy Nhon Anchorage 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 Urgent Steel Works for Tank Top Integrity
The tank top plating forms a critical structural and watertight boundary between the cargo hold and the underlying ballast tanks. On a Panamax bulk carrier, any puncture caused by falling cargo immediately compromises this separation. Failure to restore full watertight integrity can lead to cargo contamination, ballast system issues, and serious navigational risks. In addition, prolonged delays create significant commercial losses for all parties involved. Professional Steel Works by VietNam Shiprepair restore structural strength and complete isolation of the ballast tanks, ensuring safe navigation and cargo protection while minimizing downtime.
Professional Steel Works Process under NKK Class Supervision
VietNam Shiprepair executed the following controlled process for the tank top plate replacement at Quy Nhon Anchorage:
- Conducted a detailed joint inspection with the NKK surveyor to assess the extent of the puncture and define the precise renewal area.
- Submitted and obtained NKK approval for the repair plan, Welding Procedure Specification (WPS), welder qualifications, and material certificates.
- Erected safe staging and implemented full hotwork safety measures inside the cargo hold.
- Cut out the damaged tank top plating in the affected area.
- Fitted and installed new NKK-approved steel plate matching the original thickness and grade.
- Performed welding by NKK-certified welders using approved procedures.
- Carried out Non-Destructive Testing (NDT), including Ultrasonic Testing (UT) and Penetrant Testing (PT), on all welds.
- Conducted watertight testing to confirm complete isolation between the cargo hold and ballast tanks.
- Applied anti-corrosion coating and completed final visual and dimensional inspection.
- Obtained final NKK surveyor endorsement for the completed Steel Works.
This systematic approach restored full structural and watertight integrity in the shortest possible time.
