Products Description

Roller and Wheel Fenders

Roller and Wheel fenders are predominantly installed in the entrance areas of locks, dry docks and other narrow or exposed passages.

Roller fenders offer only limited energy absorption and are chosen to smoothly guide passing vessels by means of the rotation of the wheel.

Wheel fenders provide a defined energy absorption capacity in addition to guiding the vessel.

Combinations of two or more roller or wheel fenders are possible.

Selection of the appropriate type, size and casing is dependant on the specific project requirements.Despite standard tyre and roller dimensions,each fender is a tailored system. Please contact us for assistance.

Rubber properties

JRB Rubber compounds are designed for long life in marine environments. All fenders are made using high quality natural and/or synthetic rubber compounds, formulated for high performance and reliability.

Rubber compounds include additives to resist the effects of ozone and ultra-violet light. The vulcanisation process (temperature, pressure and time) is strictly controlled to ensure a homogenous product with excellent physical properties and rubber to metal bond strengths.

■ Marine grade compounds

■ Natural and/or synthetic

■ Resists ozone and UV

■ Excellent bond strengths

■ Fully homogeneous

■ Fully recyclable

JRB moulded rubber fender compounds also comply to ASTM D 2000 callouts:

Performance Testing

Jerryborg routinely tests fenders to verify their consistent performance and quality. Testing facilities are independently managed by government approved operators to guarantee the accuracy and authenticity of results. Client and third party attendance during

testing is also welcomed.

Jerryborg adopts the latest verification testing protocols defined by PIANC and ASTM to confirm fenders meet the published Rated Performance Data [RPD] for BRG cones, BRG cells and BRG elements.

Calibration	Test apparatus is calibrated to ±1% and independently certified.
ldentification	Fenders are identified with a unique serial number and job reference number to allow full document traceability. RFID tag identification is available on request for some fender types.
Sampling	10% [min)of randomly selected fenders are tested, rounded up to the nearest whole unit. More frequent testing can be carried out on request. Sampling of the remaining fenders is increased to 20% if any fender does not meet the required values and to 100% if further fenders do not meet the required values.
Dimensions	Primary dimensions of the fenders are measured and recorded.
Preparation	Prior to verification tests,fender samples will be preconditioned by compressing three or more times to rated deflection and allowed to recover for at least one hour. Fenders may then be normalised [see below] if required.
Test conditions	Test speed is steady state 0.3-1.3mm/s[typically 1mm/s] Fender temperature is normalised to 23°C±5°C Testing is under axial compression [0°angle]
Normalising	If fenders are stored at an ambient temperature of 23°C ±10℃ for more than 8 hours,then fenders shall be " normalised " in a temperature controlled environment at 23°C +5°C for a time not less than t=20 X 1-5 [where X=greatest wall thickness of rubber in metres).
Results	Reaction and deflection shall be recorded at maximum intervals of 0.01 H - 0.05 H where H=nominal fender height]. Energy absorption is integrated from the Reaction v deflection curve.
Pass criteria	Fenders pass the verification performance test if low end energy (RPD-10%tolerance] is achieved without exceeding high end reaction (RPD+10% tolerance] at any point during the compression cycle.

PIANC also requires that all rubber fender units with RPD≥1000 kN to be installed on monopiles, pile-supported jetties or other load sensitive structures shall be given at least one full compression cycle to stress relieve [conditionl them prior to use.

3 Testing of other fender types[Arch, Cylindrical etc]follows a similar format-please ask Jerryborg for details.

4 Increased test frequency is an optional extra cost item.
