What Are Sling Pneumatic Fenders

The sling pneumatic fender is like the Yokohama fender but lacks an outer net. It has three layers: an outer rubber layer, a synthetic cord layer, and an inner rubber layer. This fender has tough rubber on the outside. This rubber layer enhances resistance to operational damage. Each end of the fender is fitted with a flange, shackle, and swivel, allowing for a chain or cable attachment. These sling Yokohama fenders are designed for repeated inflation and deflation. This design makes them easy to use, transport, and store.

Sling Type Fender Features

Applicable in Various Scenarios

Sling-type fenders are remarkably versatile. They work and adapt in a myriad of scenarios. Those scenarios include ship-to-ship (STS), ship-to-berth (STB), and ship-to-quay (STQ) operations.

Minimal Reaction and Excellent Energy Absorption

Sling pneumatic fenders have excellent energy absorption capabilities. They can effectively dissipate kinetic energy during collisions. Not only this, but they also minimize reaction forces during berthing or mooring. This way, they reduce the risk of damage. They also protect the vessel and berthing structure.

Adaptability to Tidal Variations

Sling pneumatic fenders are particularly suitable for locations with changing tides. The fenders face changing water levels and the harshest environments. But, they remain unaffected by tides and keep working well. These properties give them consistent performance in a variety of conditions.

Ease of Installation and Maintenance

Sling pneumatic fenders are relatively easy to install and maintain. You can easily inflate, and use them quickly. Thanks to a simple inflation procedure, which minimizes downtime and boosts efficiency. Besides, they have a long serviceable life and do not require frequent maintenance. This results in deficient management or maintenance costs.

Flexibility in Setup

Sling-type fenders are designed to accommodate both temporary and permanent installations, allowing for easy and quick mounting in various orientations such as horizontal, vertical, or diagonal. This adaptability makes them suitable for a wide range of vessels and maritime environments.

Compliance with ISO17357:2014

Sling-type fenders are made in strict accordance with ISO17357:2014 standards. They follow and adhere to rigorous quality and safety protocols. This ensures that they meet or beat industry benchmarks. The benchmarks are for performance, reliability, and durability.
