Super Cone Rubber Fender · High Energy, Low Reaction · 500H–2000H

Super Cone Rubber Fenders for High-Energy Berths

We manufacture super cone rubber fenders whose tapered geometry absorbs a high share of the berthing energy — about 70% to 72.5% — at a low reaction force, spreading the impact so the hull and the quay take less stress. They stay stable when the vessel berths at an angle of up to 10°, come in 14 sizes from 500H to 2000H weighing 142 to 9,200 kg, and bolt down with M24 to M56 anchors. The high-strength rubber resists UV, seawater corrosion, and abrasion. We have manufactured marine fenders in Qingdao since 2005, and we confirm the body type and rubber grade — which together set the rated energy absorption and reaction force — against your berthing energy.

Applications & Working Principle

Where Super Cone Rubber Fenders Earn Their Place

Super cone fenders suit higher-energy berths that need a lot of energy absorbed at a controlled reaction force — provided the foundation can take the anchor bolts and the rubber grade is confirmed. We use them on commercial and naval berths and offshore platforms for large vessels, and we size the cone and the rubber grade from your berthing energy rather than from height alone.

How the cone absorbs energy

The tapered cone is the energy element. As a vessel pushes against it, the cone deflects and the reaction force stays low while the geometry absorbs a high share of the berthing energy — about 70% to 72.5% — and disperses the impact so the hull and dock are not point-loaded. The shape also keeps the fender stable when the vessel berths at an angle of up to 10°.

That high energy at a low reaction is the reason to choose a cone over a simpler fender: it delivers far more energy for the reaction force it passes into the quay. The trade-off is that it is a bolted, fixed unit on a solid foundation, and its rated performance depends on the rubber grade we select for the berth.

Why a cone over a cylindrical fender. The cone absorbs much more energy for the same reaction force, which protects an old quay or a sensitive hull where the reaction limit is tight. The trade-off is a larger, bolted unit on a solid foundation; for simple, low-energy berths or workboats, a cylindrical rubber fender or tug boat fender is lighter and easier to fit.

Commercial ports & terminals

High energy absorption at low reaction for large cargo and passenger vessels, dispersing the berthing force to protect hull and quay across varied traffic.

Military & naval facilities

Heavy naval vessels and high-intensity use, handled with strong impact resistance and corrosion-resistant rubber.

Offshore platforms & oil and gas

Protection against vessel impact in harsh weather and strong currents, with high-salt corrosion resistance for long service.

Sizes & Sizing

Rated Performance, Sizes & Grades

Super cone fenders come in two body types, each in 14 sizes by cone height from 500H to 2000H. Type-1 (SCB) is graded RS / RH / RO / RL — four reaction levels. Type-2 is a taller-flange body graded G4 / G3 / G2 / G1 / G0 — five levels, reaching higher energy at the top sizes. Both are rated at 70% deflection. The tables below give the rated performance for each grade, the body geometry and anchor pattern, and the PIANC correction factors.

Rated at 70% deflection, per fender. Reaction force (kN) and energy absorption (kN·m) are quoted per fender unit, not per metre. Tolerance: reaction force ≤ +10%, energy absorption ≥ -10%. Hull pressure is confirmed separately against the front-panel contact area, and the PIANC angular, temperature, and velocity factors are applied to your site before the fender is confirmed.

Reference angle is 10° (AF = 1.000) and reference temperature +23 °C (TF = 1.000). Note the angular factor peaks near 5° rather than at 0°, which is characteristic of the cone geometry. The two body types carry different velocity factors.

The most common sizing mistake. Choosing a cone by height and forgetting the grade. A 1000H in RS gives 1,339 kN at 669 kN·m; the same height in RL gives 630 kN at 350 kN·m — roughly half the energy at half the reaction. Height sets the envelope, grade sets the performance. We pick both together, apply the PIANC factors, then check reaction force and hull pressure.

Clearances & panel weight support

There must be enough space around and between the cone fenders and the steel panel to let them deflect without interference. Cone fenders can support significant static weight; the table gives the permitted frontal-panel weight before additional support chains are required.

Rubber gradeSingle or multiple horizontal (n ≥ 1)Multiple vertical (n ≥ 2)
RL — Low reactionWH ≤ n × 0.85 × wWV ≤ n × 1.0 × w
RO — Standard reactionWH ≤ n × 1.0 × wWV ≤ n × 1.25 × w
RH — High reactionWH ≤ n × 1.3 × wWV ≤ n × 1.55 × w

n = number of cone fenders; w = weight of one fender; WH = panel weight for a single or multi-horizontal arrangement; WV = panel weight for a vertical arrangement. Where the panel exceeds these limits, support chains are added. Clearance distances are for guidance — contact us if in doubt.

Construction & Mounting

Construction & How They Are Mounted

Cutaway of a super cone rubber fender with embedded flanges and a bolted steel front panel

Moulded rubber cone, bolted down

The cone is moulded from high-strength rubber with anchor bolts from M24 to M56, four to ten per model depending on size, fixing it to a solid foundation. The rubber resists UV, seawater corrosion, and abrasion for long service in harsh marine environments.

Where a berth needs a wider contact face or a lower hull pressure, the cone is supplied with a steel front panel, often faced with a UHMW-PE pad — confirmed per project. We match the panel and the mounting hardware to your structure rather than leave them generic.

High-strength rubber

Resists UV, seawater corrosion, and abrasion, holding performance through frequent, high-intensity berthing in harsh conditions.

Anchor-bolt mounting

Bolted to a solid foundation with M24 to M56 anchors, four to ten per fender by model — we confirm the bolt pattern and torque with the structure.

Low maintenance, long life

Long service life and low maintenance reduce replacement frequency and cost, which is the economic case for the cone on a busy berth.

Where This Is Not the Right Choice

When a Different Fender Fits Better

Super cone fenders are one option in our wider rubber fenders range, built for high-energy fixed berths. They are not the right fender for every job, so here is where something else fits better.

You are tight on installation depth

Where the berth needs high energy in a shorter projection, a super cell rubber fender offers a similar energy class in a different geometry.

An honest boundary. A cone fender needs a solid foundation for its anchor bolts, and the rated tables assume 70% deflection at +23 °C. Cold weather stiffens the rubber (TF rises to 1.540 at -30 °C) and a steep berthing angle derates it sharply (AF falls to 0.739 at 20°). We work the corrected figures for your berth before contract rather than read the table straight.

FAQ

Super Cone Rubber Fenders — Frequently Asked Questions

How much energy does a super cone fender absorb?

About 70% to 72.5% of the berthing energy, at a low reaction force, dispersing the impact so the hull and dock take less stress. The exact guaranteed energy absorption follows the rubber grade we select for your berth.

What berthing angle can it handle?

The cone stays stable when the vessel berths at an angle of up to 10°. Beyond the rated angle, performance derates, so we apply an angular correction factor when we confirm the size and grade.

What sizes are available?

Two body types, each in fourteen sizes by cone height from 500H to 2000H. Type-1 (SCB) weighs 142 to 9,200 kg; Type-2 weighs 165 to 9,580 kg and runs a 1050H in place of Type-1’s 1150H. Both fix with M24 to M56 anchor bolts, four to ten per fender by model.

How is the energy absorption and reaction force set?

By the height and the rubber grade together. Type-1 offers four grades (RS/RH/RO/RL) and Type-2 five (G4/G3/G2/G1/G0), so one height can span roughly a two-to-one range in both energy and reaction. The tables give the rated figures at 70% deflection; we then apply the PIANC angular, temperature, and velocity factors.

Do temperature and angle change the performance?

Yes, and the PIANC factor tables are on this page. The angular factor actually peaks near 5° and falls to 0.739 at 20°; the temperature factor runs from 0.916 at +50 °C to 1.540 at -30 °C. A velocity factor for impact duration applies too, and it differs between the two body types.

When should I use a cylindrical or cell fender instead?

Use a cylindrical fender for simple, low-energy berths and workboats where the cone’s energy is not needed. Consider a super cell fender where you need a similar energy class in a different projection. The cone suits high-energy berths with a tight reaction limit.
