When a vessel comes alongside, every eye is on the lines, the wind, the tide, the crew. But have you ever considered the importance of non-destructive bollard testing (NDT) to ensure that crucial mooring points remain safe and reliable? These assessments are no longer optional: modern vessels, stronger ropes, and extreme weather make proactive testing essential for ports and harbours worldwide.
Why Bollard Testing Has Never Been More Important
Bollards and their fixings face decades of environmental stress, including:
- Corrosion at the base or within the concrete
- Fatigue from repeated loading
- Water ingress
- Hidden cracking
- Damage from high-energy shock loads
Most of this degradation is hidden. A bollard can look perfectly sound above ground yet be one high-wind event away from catastrophic failure. That’s why bollard testing using advanced NDT methods has become the gold standard for safe moorings.
Real-World Consequences of Bollard Failure
Ports around the world have seen serious incidents due to unseen deterioration. Examples include:
- MSC Fantasia (2009) – High winds in Palma de Mallorca caused bollard failure, collapsing a passenger gangway.
- Carnival Triumph (2013) – Failed bollards led to collisions, one fatality, and extensive damage.
- VALARIS DS-16 (2022) – A deteriorated bollard failed, causing a drilling unit to drift into a cargo ship, with nearly $5 million in damages.
- Norwegian Epic (2025) – Bollard failure in Catania, Italy, led to damage to port infrastructure.
These failures often trace back to corrosion or cracking in the base, hold-down bolts, or surrounding concrete – areas that traditional visual inspections cannot fully assess.
Why Surface Methods Aren’t Enough
Magnetic Particle Inspection (MT) and Dye Penetrant Inspection (DPI) can detect surface cracks, but they cannot reveal hidden defects beneath the surface, such as:
- Internal corrosion
- Sub-surface cracking
- Concrete deterioration
- Anchor bolt weakening
- Voids
- Washouts
Relying on surface-only methods gives a false sense of security. Modern bollard testing must go deeper to ensure true structural integrity.
The Risks of Pull Testing
While some organisations use hydraulic or tug-based pull testing, this method has limitations:
- It can damage weakened bollards or foundations
- Puts personnel in dangerous zones
- Shock loads may exceed design limits
- Provides no insight into hidden deterioration
- May introduce micro-damage that worsens over time
Pull testing alone is no longer considered sufficient for modern infrastructure safety.
Modern Bollard Assessment: Non-Destructive Testing (NDT)
At EP Marine & Rail, we rely on non-destructive testing (NDT) techniques, including ultrasonic testing, eddy current testing, and ground penetrating radar (GPR). These methods allow us to:
- Detect internal cracks and corrosion
- Assess anchor bolts and buried fixings
- Map reinforcement, voids, and substrate condition
- Identify early-stage defects long before they become unsafe
- Confirm that bollards can handle modern mooring loads
- Provide detailed documentation for insurance, compliance, and harbour management
Unlike surface-only methods, our NDT techniques reveal what’s hidden, giving ports and harbour authorities a complete picture without ever stressing the bollard.
Benefits of Regular Bollard Testing
Routine NDT-based bollard testing ensures:
- Safer mooring operations for vessels and crew
- Early identification of potential failures
- Reduced risk of costly incidents or downtime
- Compliance and clear records for insurers and regulators
- A proactive approach to ageing infrastructure
Ports don’t need to wait for a visible problem – or a disaster – to take action. Regular bollard testing is a cost-effective, non-intrusive solution that protects both people and property.
The Bottom Line
Ageing bollards are under pressure like never before. Extreme weather, larger vessels, and stronger synthetic ropes mean that failure can have catastrophic consequences. Non-destructive bollard testing (NDT) provides the insight and reassurance that ports need to operate safely.
Because a bollard only has to fail once to put lives, vessels, and infrastructure at risk. Don’t wait for that moment – ensure your bollards are truly fit for purpose today.
If you’d like expert guidance on keeping your bollards safe and ensuring secure moorings for vessels and crew, EP Marine & Rail can provide professional bollard testing and assessments.
