There must be enough space around and between Super Cone fenders and the steel panel to allow them to defl ect without interference.

Distances given in the above diagram are for guidance. If in doubt, please ask.

Provenin practice



Parallel Motion technology can reduce reaction forces by up to 60% compared with traditional designs. The panel always remains vertical but can cope with large berthing angles – even at 20° there is usually no loss in energy absorption.

Features

Ultra-low reactionNon-tilt frontal panelNo performance loss at large berthing anglesEasy and fast to installMinimal maintenance

Applications

RoRo and fast ferry berthsLNG and tanker terminalsNaval facilitiesHigh tidal zonesMonopile or ‘soft’ structures

PARALLELMOTION FENDERS

Increasing energy,

reducing reaction

By using two Super Cones back-to-back, the defl ection and energy both increase whilst reaction forces stay low. Reduced loads compared to conventional fenders mean less stress in the structure, allowing smaller piles and less concrete to be used.

As Parallel Motion Fenders are mostly preassembled in the factory, installation is simple and fast. Maintenance is minimal too – contributing to the low service life cost of Parallel Motion technology.

Super Cone rubber fenders

Shown here mounted in a back-to-back ‘Twin-Series’ confi guration.

Closed box panel (frame)

Fully sealed, pressure tested design. Shown with optional lead-in bevels which are designed to suit each case.

Torsion tube and arm assembly

Also closed-box construction, the tube and arms keep the panel vertical whatever level impact loads are applied.

Hinge units

The maintenance-free stainless steel pins and spherical Trelleborg Orkot® bearings allow free rotation to accommodate berthing angles, also eliminating moments in the hinge pin.

UHMW-PE face pads

Fentek ‘Double Sintered’ UHMW-PE face pads are standard to minimise friction and maximise service intervals.

Check chains

Check chains (optional) act as rope defl ectors to stop ropes from snagging, and to help with some large angle berthings.

Pile jackets (optional)

Purpose designed for every project, pile jackets are factory built for a perfect fi t to the fender on-site. They can strengthen the structure and double as a corrosion barrier in the vulnerable splash zone. Jackets are also available for monopile systems.

Small cylindricals (≤Ø600mm) are often suspended from chains connected to brackets or U-anchors on the quay wall.

Large cylindricals (Ø900–Ø1600mm) often use a central support bar connected at each end to chains which go back to brackets or U-anchors on the quay wall.

Very large cylindricals (≥Ø1600mm) may require special ladder brackets due to their weight. These are specially designed for each application.

CYLINDRICAL FENDERS



Provenin practice



Pneumatic fenders are ideal for permanent and semi-permanent port applications and for offshore ship-to-ship transfers. They are supplied in a wide range of sizes and in standard or high-pressure versions. Smaller fenders can be supplied as Hook type. Larger fenders are commonly fi tted with a chain-tyre net (CTN) for added protection. For navy ships, a grey body is also available.

Features

Easy and fast to deployVery low reaction and hull pressureSuitable for small and large tidal rangesMaintains large clearances between hull and structure

Applications

Oil and gas tankersFast ferries and aluminium vesselsTemporary and permanent installationsRapid response and emergencies

HYDRO-PNEUMATIC FENDERSSubmarines and other vessels which contact fenders below waterline require a unique solution. Hydro-pneumatic fenders are specially adapted to this application. The fender body is partially water-fi lled, then pressurised with air and ballasted to make it stand vertically. Fender draft and performance can be tuned by altering the water:air ratio and infl ation pressure.

Features

Sub-surface contact faceVery low hull pressuresVariable draftPrevents acoustic tile damage

Applications

SubmarinesSome fast ferriesSemi-submersible oil rigs

Due to the very specialist nature of Hydro-pneumatic fenders, it is strongly advised that a detailed study be carried out for each case.

Please ask for assistance with this.



Wheel fenders are widely used on exposed corners to help ships manoeuvre into berths and narrow channels such as locks and dry-dock entrances. The main axle slides on bearings and the wheel reacts against back rollers to provide high energy and minimal rolling resistance, whilst the stainless steel and composite Trelleborg Orkot® bearings are almost zero maintenance.

Features

Highest energy absorptionVery low rolling resistanceUse singly or in multiple stacksComposite and stainless steel bearingsLow maintenance casing design

Fentek FQ1000 ultra high molecular weight polyethylene (UHMW-PE) is the fi rst choice material for facing steel fender panels and other heavy duty applications. It combines very low friction with excellent impact strength and a wear resistance much better than steel.

Most popular is FQ1000DS – a ‘double-sintered’ and work-hardened material for extra durability, which is supplied in black as standard. If colours are needed then FQ1000V ‘virgin’ grade comes in yellow, white, grey, blue, green or red.

FQ1000 UHMW-PE materials are compounded to resist ozone and UV radiation; they do not degrade or rot and are easily recycled at the end of their useful service life.

Features

Very low friction coeffi cientExcellent abrasion resistanceUV and ozone resistantDoes not rot, split or crack100% recyclable

Applications

Fender panel (frame) face padsRubbing stripsV-fender shieldsLock entrance and wall protectionBridge buttress protectionBeltings on workboats

Composite fenders* are composites of rubber for resilience and UHMW-PE for low-friction and wear resistant properties. The two materials are bonded with a special vulcanising method which is stronger and more reliable than a mechanical joint. Composite fenders are used where the simplicity of extrusions are required but with lower shear forces.

Features

Resilient rubber bodyLow-friction UHMW-PE faceStrong molecular bondEasily drilled and cutMany standard sizes

Applications

Jetties and wharves for small craftMooring pontoonsPile guides on fl oating structuresInland waterways

* Also called Rubbylene®

Fender panels are just as important as the rubber units on high performance systems. That’s why every Fentek panel is purpose designed using structural analysis programs and 3D CAD modelling for optimum strength.

Fender panels distribute reaction forces to provide low hull pressures and cope with large tidal variations. They can also be designed to resist line loads from belted ships, or even point loads in special cases. Optional lead-in bevels reduce the snagging risk, whilst brackets (where required) provide highly secure connection points for chains.

Closed box designs are used almost exclusively – all fully sealed and pressure checked. Corrosion protection is provided by high durability C5M class paint systems to ISO 12944, and additional corrosion allowances can be designed in where required.

Some fender systems need chains to help support heavy components or to control how the fender defl ects and shears during impact. Open link or stud link chains are commonly used and these can be supplied in several different strength grades.

Compatible accessories like shackles, brackets and U-anchors are also available. The nominal breaking load (NBL) of these items is matched to chains of similar capacity. Chains and accessories are supplied galvanised as standard. Chain brackets may also be supplied in an optional painted fi nish.

RUBBER PROPERTIES



All Trelleborg rubber fenders are made using the highest quality Natural Rubber (NR) or Styrene Butadiene Rubber (SBR) based compounds which meet or exceed the performance requirements of all international fender recommendations.*Trelleborg can also make fenders from other NR/SBR compounds or from other materials such as Neoprene, Butyl Rubber, EPDM and Polyurethane.

Different manufacturing processes like moulding, wrapping and extrusion need certain characteristics from the rubber. The tables below give usual physical properties for fenders made by these processes, and which are confi rmed during quality assurance tests for each order.† All test results are from laboratory made and cured test pieces. Results from samples taken from actual fenders will differ – please ask for details.

PERFORMANCE TESTING



Trelleborg is committed to providing high quality products. Consistency and performance are routinely checked in accordance with the latest procedures and test protocols.

PIANC has introduced new methods and procedures for testing the performance of fenders, allowing for real world operating conditions, in their document ‘Guidelines for the Design of Fender Systems: 2002: Appendix A’.

Type Approval Testing

Type Approval involves a rigorous series of tests to determine the effects of environmental factors on the performance of a given fender type; these include velocity, temperature, compression angle and fatigue. Type Approval tests have been conducted by Trelleborg on all high performance fenders and have been witnessed by Germanischer Lloyd. Performance values obtained from Type Approval testing are defi ned as Rated Performance Data (RPD).

Verifi cation Testing (VT)

Verifi cation testing is conducted to ensure that batches of fenders comply with the expected performance criteria, in particular the minimum energy absorption, maximum reaction force and physical properties of the rubber.

VERIFICATION TESTING



Constant Velocity (CV) Test Method

All fenders will be given a unique manufacturing serial number for traceability.Sampling is 1 in 10 fenders (rounded up to a unit) unless otherwise agreed.1

No additional break-in cycles are carried out unless otherwise agreed.1

Fender performance will be measured at 0° compression angle.Readings shall be taken at intervals of between 0.01H to 0.05H (where H = nominal fender height).Fender temperature will be stabilised to 23°C ± 5°C for at least 24 hours before compression testing.Minimum temperature stabilisation time will be calculated as tmin = 20x1.5 (where ‘x’ is the thickness of the fender body in metres).Stabilising time (tmin) can include the time taken for ‘break-in’ and ‘recovery’.‘Break in’ the fender by defl ecting it three times to rated defl ection.Remove load from the fender and allow ‘recovery’ for at least 1 hour.Defl ect the fender once at a constant defl ection speed of 0.0003–0.0013m/s (2–8cm/min) and record reaction and defl ection.Stop testing when defl ection reaches rated defl ection or RPD is achieved.

The Trelleborg procedure for testing and reporting the performance of ‘solid-type’ rubber fenders is in accordance with PIANC ‘Guidelines for the Design of Fender Systems: 2002: Appendix A: Section 6: Verifi cation/Quality Assurance Testing’.

This procedure refers to ‘solid-type’ rubber fenders including Super Cone, Cell Fender, Unit Element, MV and MI Elements, Arch Fender, Cylindrical etc.

Test Apparatus & Reporting

The test apparatus shall be equipped with a calibrated2 load cell system and linear transducer(s) for measuring displacement. These will provide continuous real-time monitoring of fender performance.Test reports shall include the following as a minimum:

Serial Number and description of test fender.Date of test, name of test supervisor and signature of Quality Manager.Table and graph of reaction (RVT) versus defl ection and energy (EVT) v defl ection.

Pass Criteria4

Fenders have passed verifi cation testing5 if they meet the following conditions:

RVT ≤ RRPD × 1.1 × VF × TFEVT ≥ ERPD × 0.9 × VF × TF

Where,RVT = reaction from verifi cation testingRRPD = Rated Performance Data

(or customer’s required reaction)EVT = energy from verifi cation testingERPD = Rated Performance Data

(or customer’s required energy)VF = velocity factor for actual test speed

(or 1.0 unless otherwise stated)TF = temperature factor for stabilised temperature of

sample (or 1.0 unless otherwise stated)

PIANC FACTORS



All performance values for PIANC Type Approved fenders are quoted as Rated Performance Data (RPD) and are normalised to:

Initial Velocity, Vi 150mm/sTemperature, T 23°C ±5°CCompression Angle, α 0°

When test or actual operating conditions vary from RPD conditions then factors should be applied to the fender performance. Examples are given below:

Verifi cation Testing

Fender SCN300 (E1.2)RRPD 68kN (±10%)ERPD 9.2kNm (±10%)Test Speed 1mm/sTemperature 30°CCompression Angle 0°

Velocity Factor (VF)

Under constant rate defl ection, the compression time (t) is:

t = d/V = 0.72 × 300 / 1.0t = 216 seconds

At 216s, from the table on p7:VF = 1.000

Temperature Factor (TF)

At 30°C, from the table on p7:TF = 0.969

Angle Factor (AF)

At 0°, from the table on p7:AF = 1.000

Test Results

Assuming the verifi cation test results are:RVT = 70.5kNEVT = 9.5kNm(at 1mm/s, 30°C and 0° angle)

Comparing test results with RPD:RRPD × 1.1 × VF × TF × AF= 68 × 1.1 × 1.000 × 0.969 × 1.000= 72kN ≥ RVT Passed

ERPD × 0.9 × VF × TF × AF= 9.2 × 0.9 × 1.000 × 0.969 × 1.000= 8.0kNm ≤ EVT Passed

The example fender has passed the test.

Real Operating Conditions

Fender SCN1600 (E2.5)RRPD 2668kN (±10%)ERPD 2215kNm (±10%)Impact Speed 120mm/sTemperature 0–38°CCompression Angle 15°

Velocity Factor (VF)

Assuming steady state deceleration, the compression time (t) is:

t = 2d/V = 2 × 0.72 × 1600 / 120t = 19.2 seconds

At 19.2s, from the table on p7:VF = 1.000

Temperature Factor (TF)

At operating temperature 0–30°C, from the table on p7:TF0 = 1.099 (at 0°C)TF38 = 0.935 (at 38°C) – by interpolation

Angle Factor (AF)

At 15°, from the table on p7:AF0 = 1.000 (at 0°)AF15 = 0.856 (at 15°)

Operating Performance

Under actual operating conditions the chosen fender performance will be:

RACTUAL ≤ RRPD × VF × TF0 × AF0

= 2668 × 1.000 × 1.099 × 1.000= 2932kN(at 120mm/s, 0°C and 0° angle)

EACTUAL ≥ ERPD × VF × TF38 × AF15

= 2215 × 1.000 × 0.935 × 0.856= 1773kNm*(at 120mm/s, 38°C and 15° angle)

* Actual values above do not include fender manufacturing tolerances.
