Exceptional Energy Absorption Capacity per Unit
The volumetric efficiency of the pneumatic fender allows it to
achieve a very high energy absorption capacity relative to its
physical size and weight. This is a critical advantage in offshore
logistics, where deck space and lifting capacity are limited. Our
advanced design maximizes internal air volume and optimizes the
compression curve to deliver one of the highest kJ/tonnage ratios
in the industry.
Outstanding Stability with External Bead Rings
A key differentiator for offshore use is stability. Our fenders are
equipped with robust, integrally molded external bead rings. These
rings act as anchors, significantly increasing the fender's
resistance to rolling and twisting upon impact, especially at high
deflection angles. This ensures consistent contact and load
distribution, which is non-negotiable for protecting expensive
vessel hulls and offshore structures.
Superior Tear and Abrasion Resistance
We utilize a proprietary rubber compound with enhanced tear
strength and high resistance to cutting, chipping, and abrasion.
This is specifically engineered to withstand the harsh conditions
of offshore environments, including contact with rough hull
surfaces, debris, and prolonged UV exposure, thereby extending the
service interval and reducing lifetime operating costs.
Integrated Lifting and Mooring Points
For safe and efficient handling, our offshore-grade fenders come
with integrally vulcanized, high-strength pad eyes or lifting lugs.
These are designed with a significant safety factor and are tested
to handle the dynamic loads encountered during deployment,
retrieval, and mooring operations, ensuring operational safety for
crew and equipment.
Applications
Offshore Heavy Lift and Construction Operations
Essential for cushioning heavy-lift vessels during the
loading/unloading of massive structures like oil & gas modules,
offshore wind turbine components, and other outsized cargo where
contact forces must be meticulously controlled.
STS Operations for LNG and Crude Carriers
The high energy capacity and stability are crucial for the safe
side-by-side mooring of large LNG carriers and VLCCs during cargo
transfer. The fenders prevent hull-to-hull contact that could lead
to catastrophic consequences, ensuring the integrity of the cargo
containment systems.
Floating Dock and Barge Fendering
Used as primary or secondary fendering on the sides of floating
docks, repair quays, and large barges, providing a resilient and
high-capacity buffer against berthed vessels, even in fluctuating
tidal zones.

FAQ
Q1: What is the difference between standard and offshore grade
pneumatic fenders?
A: Offshore-grade fenders feature enhanced construction: thicker
rubber walls, higher-grade steel cord reinforcement, more robust
bead rings, and superior anti-abrasion compounds to withstand the
harsher mechanical and environmental loads of offshore operations.
Q2: How is the internal pressure of the fender monitored and
maintained?
A: Fenders are supplied with a recommended initial internal air
pressure. This can be checked with a standard pressure gauge via
the integrated valve. For critical applications, we can install
permanent pressure sensors for real-time monitoring.
Q3: Are your fenders suitable for use in extreme cold climates?
A: Yes, we offer special low-temperature rubber compounds that
remain flexible and retain their physical properties at
temperatures as low as -40°C to -50°C, preventing brittleness and
cracking.
Q4: What is your warranty policy?
A: We offer a standard warranty against manufacturing and material
defects, typically for 3-5 years from the date of shipment, subject
to proper use and maintenance as per our guidelines.
Q5: Can you provide type approval certificates from classification
societies?
A: Absolutely. We can provide certified copies of type approval
certificates from major societies like DNV, LR, and ABS upon
request, confirming the fender's compliance with international
standards.
