Pneumatic Fenders Suppliers

Pneumatic fenders absorb more energy per kilogram than any other type of floating fender, which is why they dominate ship-to-ship petroleum transfer and offshore loading worldwide. Built to ISO 17357-1 type approval at 50 kPa or 80 kPa working pressure, a high-pressure floating rubber fender stays in service for 8 to 12 years across hundreds of berthings if it is sized correctly and inspected on schedule. Pneumatic fender suppliers stock the full ISO 17357 range alongside the chain matrices, swivel shackles, inflation valves, and end fittings needed to put the bladder into useful service on a working tanker.

50 kPa vs 80 kPa - Working Pressure and Energy Absorption

Pneumatic fender working pressure decides energy absorption capacity, recovery rate, and the operating envelope the unit is rated for. ISO 17357-1 covers the high-pressure range: a 50 kPa fender delivers a softer reaction at deeper compression and is the standard call for routine STS work, while an 80 kPa unit stores more energy in the same envelope and is used where vessel approach speed or displacement is higher. ISO 17357-2 covers low-pressure (30 kPa) fenders for sheltered berthing and smaller vessels. The guaranteed energy absorption (GEA) value published against each size and pressure grade is the figure procurement compares, and the figure that must clear the receiving hull plate pressure limit at maximum compression.

Size Ranges and the Vessels They Serve

Pneumatic fender sizing scales from 1000 by 1500 millimetre units suited to workboat and small tanker operations to 4500 by 9000 millimetre fenders deployed between aframax and VLCC during oil transfer. A 3300 by 6500 unit weighs roughly 3.8 tonnes dry and is the workhorse size across most STS work; the largest 4500 by 9000 sits closer to 8 tonnes saturated and is reserved for the heaviest crude transfer cases. Established suppliers match size to vessel class, berthing energy, and approach geometry, rather than shipping whatever sits closest in catalogue stock.

Net Type, Netless, and Sling Configurations

The same fender size ships in three external configurations. Chain-and-tyre net wraps the bladder in a galvanised chain matrix with retired aircraft tyres as wear pads, and is the durable choice for repeated STS contact where chafing against the receiving hull is heavy. Netless fenders strip the protection back for lighter berthing where reduced cost and easier inflation handling outweigh the shorter abrasion life. Sling-type configurations carry integrated lifting and handling slings for vessels with dedicated stowage cradles. Each configuration has its place; the supplier should explain which one fits the operating profile rather than defaulting to the cheapest build.

ISO 17357 and the Certification Trail

Tanker STS work requires ISO 17357 type approval on the fender plus class type approval issued by DNV, ABS, Lloyd's Register, Bureau Veritas, RINA, or ClassNK. The full paperwork pack usually includes the original factory chain-pull test report, fabric layer build record, hydrostatic test data, and the manufacturer's working pressure declaration. Once the unit enters service, the 24-month inspection rhythm under ISO 17357-1 brings a recurring documentation cycle; chain-pull rigs and ISO audit infrastructure live mostly with the workshops, so operators typically contract the cycle out to dedicated fender inspection and recertification services that issue the recertificate against the original factory chain.

OEM Channels, Yokohama Dominance, and Counterfeit Defence

Yokohama is the dominant brand on the pneumatic floating fender market, with deployment across most large tanker fleets and STS terminals. Trelleborg through its FenderCare and Marine division, Sumitomo Rubber, ShibataFenderTeam, Bridgestone, Palfinger, and Hi-Tech Elastomers cover the rest of the global supply across high-pressure and low-pressure ranges. On the Asian side of the market, Yancheng Goodly and several Chinese OEMs hold credible production capability for ISO 17357 type-approved fenders at price points below the Japanese majors. Counterfeit Yokohama-look-alike fenders remain a real risk; vetted vendors carry serial numbers verifiable against the manufacturer and ship the factory chain-pull report with the unit.

Accessories, Inflation Equipment, and Deck Handling

A pneumatic fender deployment package extends well past the bladder itself. Chain-and-tyre nets need periodic renewal, end fittings and swivel shackles wear, inflation valves and pressure relief valves require inspection, and operators rely on portable air compressors and pressure gauges to hold working pressure between contracts. On the handling side, a 4.5 by 9 metre Yokohama-type pneumatic weighs close to 8 tonnes saturated, and that weight is what makes a davit a mandatory part of any deck installation. Procurement teams often pair the pneumatic order with vetted fender davit suppliers that match the SWL and reach to the specific fender size shipping with the deck.

Shortlisting a Pneumatic Fender Vendor

When you shortlist potential pneumatic fender vendors, weigh the practical evidence:

• ISO 17357 type approval at the working pressure - 50, 80, or 30 kPa as needed, delivered with the factory chain-pull test report rather than offered on request.
• Class certification matched to the registry - DNV, ABS, LR, BV, RINA, or ClassNK type approval references included in the quotation.
• Net configuration options - chain-and-tyre net, netless, and sling, with prior project history on similar STS or berthing operations.
• Verifiable OEM channel - authorisation or named factory chain for Yokohama (dominant in pneumatic), Bridgestone, Trelleborg, ShibataFenderTeam, or Sumitomo; serial numbers traceable back to the manufacturer.
• Accessory and inflation kit on one quotation - chain-and-tyre nets, swivel shackles, end fittings, inflation hoses, and compressors available with the fender, not as a separate procurement cycle.

The pneumatic fender suppliers listed below carry the ISO 17357-approved range, brand authorisation, and accessory coverage tanker and STS operators rely on to clear the next contract without a paperwork gap.
