Marine bumper dock fenders 3.3*11.5m
Product Introduction

Marine bumper dock fenders, also known as pneumatic fenders, rubber fenders, or Yokohama fenders, are top-of-the-line anti-collision devices in the marine industry. These fenders are crafted from rubber and multiple layers of rubber-dipped tyre fabric.
Today, they have emerged as the go-to choice for safeguarding ships in various marine scenarios. Whether it's preventing collisions between ships (ship-to-ship - STS), when a ship approaches a quay (ship-to-quay - STQ), or during the berthing process (ship-to-berthing - STB), marine pneumatic rubber fenders play a crucial role.
Their wide range of applications makes them indispensable in the maritime world. They are extensively utilized for large tankers, different types of vessels, docks, harbor wharfs, and even ocean platforms. This widespread use is a testament to their effectiveness in protecting valuable marine assets from the damaging impacts of collisions.
