In breakbulk and bulk shipping, hatch cover integrity is crucial to prevent cargo damage, insurance claims, and operational losses. Water ingress from poorly sealed hatch covers can cause cargo spoilage, contamination, and structural damage—leading to millions in annual financial losses.
Nordic Maritime Solutions offers advanced Ultrasonic Hatch Cover Testing to detect leaking hatch covers before they cause costly problems. Our precise inspections help ship owners, charterers, and insurers ensure compliance with international regulations and protect cargo during sea transport.
With a proven track record of over 4,000 operations across six continents and a 97.7% client retention rate, Nordic Maritime Solutions is a trusted leader in cargo protection and marine safety compliance.
What Is Hatch Cover Tightness Testing?
Hatch Cover Tightness Testing, often initiated after a visual inspection, is essential to prevent leaking hatch covers and ensure the cargo hold remains weathertight.
While traditional methods like hose and chalk testing, used on hatch coamings, exist, they’re less accurate and efficient, especially in challenging weather conditions, and can contribute to environmental damage.
This is making it more important to check the water tightness of cargo holds.
📌 Today, Ultrasonic Testing (UST) has emerged as the most effective and widely accepted method for ensuring hatch cover integrity, offering a non-invasive, highly precise alternative.
It is our mission to help you succeed with your projects
Traditional Hatch Cover Tightness Testing Methods
Traditionally, two methods were used to check hatch cover tightness and determine risk of water damage in an operation: hose testing and chalk testing.
However, their effectiveness at properly identifying leaks was limited.
1. Hose Testing
- Involves spraying water over closed hatch covers to detect leaks.
- Limitations:
✅ Time-consuming and labor-intensive.
✅ Difficult to detect small leaks or weak sealing areas.
✅ Cannot be performed when cargo is already loaded, increasing delays.
2. Chalk Testing
- Involves applying chalk to hatch cover seals, then closing and reopening the covers to check for seal marks.
- Limitations:
✅ Lacks precision in identifying exact leak locations.
✅ Does not detect small cracks or micro-gaps in the seals.
✅ Affected by operator error, leading to inconsistent results.
📌 Due to these limitations, the shipping industry now prefers Ultrasonic Hatch Cover Testing, which provides unmatched accuracy and efficiency.
Ultrasonic Hatch Cover Testing: The Modern Solution
What Is Ultrasonic Hatch Cover Testing?
Ultrasonic Hatch Cover Testing (UST) is a non-invasive, highly accurate method using an ultrasoundtransmitter. This hatch cover tester uses high-frequency sound waves to detect gaps, cracks, leakage, or weaknesses in hatch cover seals.
The process involves:
- Placing an ultrasonic transmitter inside the cargo hold.
- Closing and sealing the hatch covers.
- Using an external receiver to detect any escaping sound waves, pinpointing even the smallest leaks.
📌 This method ensures absolute precision, making it the preferred standard for hatch cover inspections.
Why Is Ultrasonic Hatch Cover Testing Essential?
1. Preventing Cargo Damage & Financial Losses
- Water ingress leads to cargo contamination, corrosion, and spoilage.
- Prevents costly insurance claims and supply chain disruptions.
2. Ensuring Compliance with Global Shipping Regulations
- Hatch covers must meet international sealing standards to ensure safe transit.
3. Providing Legally Defensible Documentation
- A certified ultrasonic test report acts as proof that hatch covers were sealed correctly.
- Supports P&I Clubs and marine insurers in claim disputes.
4. Enhancing Vessel Safety & Crew Protection
- Reduces the risk of hatch cover failure at sea, which can lead to structural damage or ship instability.
- Ensures the crew operates in a safer work environment.
Ultrasonic Testing is cost-effective, highly accurate, and environmentally friendly, making it the preferred hatch cover testing method worldwide.
