ISO 17357 Pneumatic Rubber Fenders

  Pneumatic rubber fenders are critical marine mooring and docking protective systems designed to absorb heavy kinetic energy during ship-to-ship (STS) transfers and port berthing operations. Manufactured in strict compliance with ISO 17357-1:2014 standards, these floating fenders offer high energy absorption and low reaction force, minimizing hull pressure and safeguarding maritime vessels against damage. Featuring multi-layer synthetic-tyre-cord reinforcements, they ensure maximum durability, weather resistance, and performance consistency under extreme tidal and deep-sea conditions.

Product Structure-  Florescence Yokohama Pneumatic Rubber Fender With Factory Price

The raw material of the Pneumatic rubber marine fender is natrual rubber +synthetic-tyre-cord fabric.

1.Outer rubber layer:

Rubber layer that covers the outside of the fender to protect the cord layers and the inner liner rubber from abrasion and other external forces.  

2.Inner rubber layer:

liner of a rubber membrane that seals the pressurized air inside the fender.(In general,we will make some inner rubber container in advance and inflate them.few days later,we will test the pressure again.The one which it's pressure did not change is good one.We will put it into store and when clients order we can use it directly.This can ensure every fender we send to client is airtight one).

3.Synthetic-tyre-cord layer for reinforcement layer:

layer made of synthetic-tyre-cord fabric which maintains the internal air pressure of the fender.

Product Application (Pneumatic Fender Uses)

Pneumatic floating rubber fenders are widely utilized across global maritime industries due to their high adaptability, reliability, and superior energy dynamics. Primary deployment scenarios include:

➢ Tankers, LPG/LNG carriers and bulk cargo vessels

➢ High-speed ferries and aluminum-hulled ships

➢ Both temporary and permanent mooring installations

➢ Standoff protection fenders for accurate vessel positioning against shore facilities

Core Advantages 

1. Compliance with ISO 17357-1:2014: Fully certified to ensure accurate material formulations, thickness tolerances, and burst pressure parameters.

2. Low Reaction Force and High Energy Absorption: Absorbs heavy kinetic energy while distributing the reaction force evenly over a large contact area, maintaining low hull pressure limits to protect sensitive ship hulls.

3. Heavy-Duty Aircraft Tyre Chain-and-Wire Net (CTN): Equipped with protective nets made of recycled aircraft or truck tyres connected by heavy-duty galvanized chains, providing maximum abrasion defense against rugged hull friction.

4. Outstanding Angular Stability: Maintains seamless energy absorption metrics at oblique berthing angles up to 15 degrees without performance degradation.

5. Cost-Effective Logistics: Fenders can be deflated and compactly folded for shipping, greatly minimizing international freight costs.

Frequently Asked Questions

Q1: What are the primary advantages of pneumatic rubber fenders compared to solid rubber fenders?

A1: Pneumatic rubber fenders utilize compressed air as a cushioning medium, which provides much higher energy absorption combined with significantly lower reaction forces. This distributes hull pressure evenly, preventing localized damage. They also float on water, adapting naturally to extreme tidal fluctuations, and can be deflated for economical transport.

Q2: Why is the ISO 17357-1:2014 certification vital for marine pneumatic fenders?

A2: ISO 17357-1:2014 is the definitive international standard regulating the design, material properties, testing, and inspection of floating pneumatic rubber fenders. It guarantees that the fender can safely handle designated berthing loads, internal test pressures, and material degradation factors under severe deep-sea working environments.

Q3: How do I select the right size of pneumatic fender for my vessel or berth?

A3: Sizing relies on calculating the vessel's maximum kinetic berthing energy. Key variables include the vessel's displacement (tonnage), berthing speed (velocity), approach angle, and external environmental factors like wind and current. Our marine engineering department provides precise mathematical models to determine the optimal fender diameter and length.

Q4: What is the difference between a Chain-and-Tyre Net (CTN) type and a Sling type pneumatic fender?

A4: Chain-and-Tyre Net (CTN) fenders are covered by a heavy-duty grid of high-tensile chains and rubber tyres (often aircraft tyres) to shield the inner body from abrasion and cuts. Sling-type fenders do not have a net, leaving the smooth outer rubber exposed; they are lightweight, easier to handle, and typically used for small-to-medium vessels or lightweight operations.

Q5: What initial internal pressures are standard for pneumatic fenders?

A5: There are two standard initial internal pressures: 50 kPa (P50) and 80 kPa (P80). P50 offers lower reaction forces for lighter hull requirements, while P80 provides much higher energy absorption capabilities for large-scale maritime vessels and rougher wave actions.
