Pneumatic Fenders (YOKOHAMA Type)

Product catalog summary

Overview: This document provides technical specifications and dimensions for Yokohama type pneumatic rubber fenders, specifically focusing on two pressure categories: 50Kpa and 80Kpa. These fenders are used in marine applications to absorb energy and reduce reaction forces during vessel docking.

50Kpa Pneumatic Rubber Fender:

Nominal Sizes: Range from 500x1000 mm to 4500x12000 mm.
Initial Internal Pressure: 50 kPa.
Guaranteed Energy Absorption (GEA): Varies from 6 kNm to 6473 kNm depending on size.
Reaction Force at GEA: Ranges from 64 kN to 7984 kN.
Hull Pressure at GEA: Not specified for all sizes, but generally around 128-158 kPa.
Safety Valve Setting Pressure: 200-250 kPa.
Testing Pressure: 250 kPa.
Weight: Fender body weight ranges from 22 kg to 4790 kg, with additional weights for net and sling types.

80Kpa Pneumatic Rubber Fender:

Nominal Sizes: Range from 500x1000 mm to 4500x12000 mm.
Initial Internal Pressure: 80 kPa.
Minimum Endurable Pressure: Varies from 160 kPa to 208 kPa at 0% deflection.
Safety Valve Pressure Setting: 250-300 kPa.
Test Pressure: 480-560 kPa at 0% deflection.
Guaranteed Energy Absorption (GEA): Ranges from 8 kJ to 9037 kJ.
Reaction Force at GEA Deflection: Ranges from 85 kN to 10490 kN.
Hull Pressure at GEA Deflection: Ranges from 160 kPa to 202 kPa.

Custom Sizes: Available upon request for both 50Kpa and 80Kpa fenders.
