Qingdao SunKai Marine Supplies Co., Ltd. directly sells Ship Berthing Floating Rubber Fender System, protected by tire chain net wrapping, with convenient sling type installation. Suitable for all types of vessel berthing protection. Welcome new and existing customers to inquire and order.
The Ship Berthing Floating Rubber Fender System, commonly known as Yokohama Fender, is a floating rubber fender inflated with compressed air. It consists of an outer abrasion-resistant rubber layer, multi-layer synthetic cord reinforcement, and an inner airtight rubber layer, with hemispherical metal valves at both ends, integrally vulcanized. It serves as a shock absorber between vessels (STS) or between vessel and dock (STD), absorbing berthing energy through air compression.
1. High energy absorption with low reaction force: Approximately 80% of berthing energy is absorbed through air compression, with peak energy at 60% deflection. Reaction force is only 1/3 to 1/2 of solid fenders at the same energy level.
2. Self-adapting to tidal variations: Floating design automatically adjusts position with water level changes, no need for installation height adjustment due to tides.
3. Dual protection with tire chain net: External protection net made of used tires and galvanized chains effectively distributes concentrated loads and prevents sharp object scratches.
4. Flexible installation and reusable: Sling or net type installation, no dock embedded fixtures required, can be flexibly moved between berths.
5. Excellent durability: 3000 cycles without cracks or GEA reduction per ISO 17357, service life of 6-10 years under normal conditions.
6. Complete specifications and customization: Diameter from 500mm to 4500mm, length from 1000mm to 12000mm, P50/P80 pressure ratings available.

Qingdao SunKai Marine Supplies Co., Ltd. has established a comprehensive quality management system certified to ISO 9001:2015. Each fender undergoes strict inspection from raw material incoming to finished product outgoing, including raw material inspection, production process monitoring, appearance and dimension inspection, 24-hour air tightness test, hydrostatic pressure test at 1.5x working pressure, and compression performance test. Classification society inspection (CCS, BV, ABS, DNV, LR, NK) available upon request.
Installation steps: (1) Pre-installation inspection: Check fender appearance, verify accessories (slings, chains, tires, shackles, pressure gauge), prepare air compressor, clear installation area. (2) Inflation: Place fender flat, connect air hose, inflate slowly to 50% rated pressure and check for leaks, then continue to rated pressure (P50=50kPa, P80=80kPa), close valve, wait 30 min to confirm pressure stable. (3) Tire chain net assembly: Arrange tires evenly, connect with galvanized chains, fix end tires with radial chains. (4) Sling installation: High-strength nylon slings connected to end lifting lugs with shackles, add rubber pads at contact points. (5) Lifting and positioning: Lift horizontally with crane, lower to water or berthing position, fix slings to bollards, adjust position, perform test berthing for acceptance.
Monthly: Check inflation pressure (within ±5% of rated), inspect for cuts/cracks, check tire chain net condition. Quarterly: Fresh water rinse, check tire wear, inspect slings and chains for corrosion. Annually: Full inspection, 24-hour air tightness test, corrosion protection for metal fittings. Service life: 6-10 years under normal conditions with proper maintenance.
All products comply with ISO 17357-1:2014 (High-pressure floating pneumatic rubber fenders) and ISO 9001:2015 quality management system. Classification society inspections available: CCS (China), BV (France), ABS (USA), DNV (Norway), LR (UK), NK (Japan). Each fender is factory-tested including 24-hour air tightness test, hydrostatic pressure test at 1.5x working pressure, and compression performance test. Product certificate and inspection report provided with each shipment.
A: 6-10 years under normal conditions, depending on usage frequency, environment, and maintenance.
A: P50 (50kPa) has softer reaction force for vessels under 80,000 DWT; P80 (80kPa) has higher energy absorption for large vessels over 80,000 DWT (VLCC/LNG).
A: Minor cuts can be repaired with rubber repair compound; deep cuts or punctures require factory repair followed by air tightness and hydrostatic tests.
A: No, each tire is independently connected and can be replaced individually. Keep spare tires and chains available.
A: Yes, our low-temperature resistant rubber formula works from -30°C to +60°C. Adjust inflation pressure for temperature changes.
