Importance of Ultrasonic Testing for Hatch Covers on Panamax Ships

Hatch covers on Panamax bulk carriers (60,000-80,000 DWT) are critical for protecting dry bulk cargo, such as coal or grain at Da Nang Port, from water ingress and environmental damage. Ultrasonic Testing is a non-destructive method to detect leaks, cracks, or wear in hatch covers, ensuring watertight integrity and preventing costly cargo damage. At Da Nang, where humid coastal conditions and frequent rains accelerate corrosion, regular Ultrasonic Testing by Vietnam Shiprepair’s Marine Services ensures vessel safety, compliance with IACS/IMO standards, and client satisfaction, even under demanding operational schedules.

Why Choose Ultrasonic Testing?

Ultrasonic Testing is the preferred method for hatch cover inspections due to its precision and efficiency. Compared to hose or chalk tests, it:

• Detects micro-leaks invisible to the naked eye.

• Identifies structural weaknesses in hatch cover joints or seals.

• Minimizes downtime, critical for vessels at Da Nang Port operating on tight routes.

• Ensures compliance with IACS UR S14 and IMO SOLAS Chapter II-1, mandatory for seaworthiness certification.

Our Vietnam Workshop teams use advanced ultrasonic equipment to deliver accurate results, safeguarding your cargo and vessel.

Steps to Perform Ultrasonic Testing for Hatch Covers

Vietnam Shiprepair recently conducted Ultrasonic Testing on four hatch covers of a Panamax bulk carrier at Da Nang Port, adhering to strict IACS/IMO protocols. Here’s the detailed process:

1. Preparation and Safety Setup
   Our Vietnam Workshop team coordinates with the ship’s crew to ensure safe conditions at Da Nang Port’s Tien Sa or Han River terminals. We erect sturdy scaffolding for access to elevated hatch covers (5-10m above deck) and equip workers with full PPE (harnesses, helmets, gloves), complying with IMO safety regulations. Weather checks prevent disruptions from Da Nang’s coastal rains or winds.

2. Equipment Calibration
   Certified technicians calibrate ultrasonic testing devices (e.g., Class-approved models like SDT Sherlog) to detect leaks with high accuracy. The device emits ultrasonic waves and measures reflections to identify defects.

3. Ultrasonic Testing Procedure

   • Close all hatch covers securely.

   • Place an ultrasonic transmitter inside the cargo hold to emit sound waves.

   • Use a receiver on the deck to scan hatch cover seals, joints, and cleats for leaks, indicated by sound wave loss.

   • Mark areas with detected leaks or weaknesses for further inspection.

4. Inspection and Maintenance

   • For identified leaks, inspect rubber seals (packing rubber) for wear or damage, replacing them if necessary.

   • Check cleats and hydraulic systems for corrosion or misalignment, common issues in Da Nang’s humid environment.

   • Apply anti-corrosion coatings (e.g., epoxy) and lubricate moving parts to restore functionality.

5. Reporting and Certification
   Generate a detailed hatch cover survey report, reviewed by classification societies like NK or DNV, to confirm IACS/IMO compliance. At Da Nang, the Da Nang Port Authority may verify results for operational clearance. The process typically takes 2-3 days for four hatch covers.
