FENDER

LEXXON marine fenders are found in applications ranging from piers, docks, dolphins and other harbor
structures, to tugs, barges, ferries and similar hard working vessels subject to frequent and severe impact.
LEXXON's well-designed marine fender system, tailored to specific vessel requirements, will protect a berthing
facility and vessels for many years with minimal upkeep and/or future modification. LEXXON marine fenders
are available in a range of rubber compounds to meet the most demanding service conditions. All are designed
to provide an excellent combination of tensile strength, resilience and energy absorption.

Applications:

Container berth General cargo berth

Oil terminal LNG & LPG terminal

Ore berth Shipyard

RoRo berth Bridge protection

Fender

Super Cell Rubber Fender
Super Cell Rubber Fenders provide good energy capability owe to the cylindrical shape with circular design
and circular mounting base. They are ideally suited to applications in oil and LNG facilities, offshore platforms,
bulk terminals, container berths, RoRo and cruise terminals, that are subject to circular motion and extreme
weather conditions or where heavy and angular berthing may be required.

Super Cone Rubber Fender
Super Cone Rubber Fenders provide excellent energy capability with low reaction base on the conical shape
combining the very best of both attributes of cell and leg fender design and construction, well suited to berths
and terminals handling large vessels. With optimal design and high performance capabilities, super cone
fender can be used instead of a larger cell fender.

Features:
High efficiency (the energy absorption doubles comparing with the super cell rubber fender with same spec.)
Excellent angular performance
Wide range and sizes
Ideal for application of berths and terminals handling large vessels

Installation

The Super Cone Rubber Fender has the similar installation ways with Super Cell Rubber Fender. The whole
system includes Cone Rubber Fender body, Front Panel equipped with UHMW-PE face pad, Chains system
(tensile chain, weight chain, shear chain). Meanwhile, the cone fender system can be installed by two or more
fender bodies with one front panel horizontally or vertically.

Super Arch Rubber Fender
Super Arch rubber fenders are manufactured using a twin leg system and can be mounted on a quay wall
horizontally or vertically to provide long lasting and low maintenance protection. The front face has a high
friction to limit vessel movement that is ideal for smaller vessels where friction is not a problem.

Super arch rubber fender has the higher performance than the traditional V & M type rubber fenders. Based on
the same unit weight of rubber, the energy absorption of super arch rubber fenders is 2.3 times higher than D
type rubber fender, 3.5 times higher than the cylindrical rubber fenders.

Super arch rubber fenders also can be bolted with UHMW-PE face pads, combining resilience with low-friction,
non-marking properties, called SA. This design can reduce the torsion the bottom of the fender dramatically,
then prolong the life-span of rubber fender body. The UHMW-PE face pads have various colors, and can be
replaced easily. SA and SAP Arch Rubber Fenders are available in many sizes from 200mm to 1000mm high
and in lengths of 1000mm to 3500mm. There are many types of rubber compounds as standard. Special
requirements also are available.

Features:
Easy to install and maintain
Tough and reliable design
High energy absorption and low reaction force
Wide ranges of sizes and energy capacities
Bolted-on UHMW-PE reduce the friction factor and shear force

Leg Rubber Fender

Leg Rubber Fenders are modular units with an advanced geometry that combines high performance with an
adaptable design. Leg rubber fenders system is the pair Leg Fenders with steel panels and UHMW-PE face
pads. Leg rubber fenders can be assembled with many methods, vertical or horizontal mounting of units
ensures optimum energy and low reaction. A small footprint makes Leg rubber fenders perfect where fixing
area is restricted. These systems are widely used for where larger vessels berth including Container Quays,
Tanker Terminals, Bulk Cargo and RoRo berths. The versatility of Leg rubber fenders make them suitable for
almost all applications.

Ladder Rubber Fender

Ladder Rubber Fenders are very robust but remain flexible to reduce accidental damage and help protect the
wharf when small craft berth.

Modular ladders are flexible, corrosion resistant and can withstand most accidental impacts from smaller
vessels. The step modules are made from polyurethane and can be linked together, combined with extensions
and a variety of optional handrails to suit many applications.

Roller Rubber Fender

Roller Fenders are commonly used on the berth corners and dock entrances, also widely installed along the
walls of dry docks and other restricted channels to help guide vessels and prevent hull damage.

The wheels mounted on a fixed axle, supported by a special frame. And wheels can be rotated freely when the
ship hull contact / slid the along with the wheels. Roller Fenders combine reasonable energy absorption with
low reaction at all berthing angles.

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

Pneumatic Fenders Type
Type I Net-type Floating Pneumatic Rubber Fenders
The fender is covered by a protection net consisting of either chain, wire or fiber and usually with tires or
rubber sleeves.
Type II Sling type Floating Pneumatic Rubber Fenders
The fender is designed to be used without a protection net. It's easy to handle because of their light weight.

Ber thing Velocity

Berthing velocity is an important parameter in fender system design, which depends upon the sizes of vessel,
loading condition, port structure and the easy or difficulty of the approach etc. Therefore the berthing velocity is
preferred to be obtained from actual measurements or relevant existing statistic information. When the actual
measured speed velocity is not available, the BSI and PIANC etc. standard shall be adopted to determine the
required velocity value from the following chart.

b Difficult berthing and sheltered

Cm Added Mass Coefficient (Cm)

When the ships berth at the dock, the body of water carried along with the ship as it moves sideways through
the water. As the ship is stopped by the fender, the momentum of the entrained water continues to push against
the ship and this effectively increase its overall mass. The mass of specified water is called Added Seawater
Mass, the added seawater influence coefficient is called Cm, normally calculated as the following formula

D-Draft
L-Ship length ΠD 2Lρ
Cm=1+
ρ (ρ=1.025t/m3) Seawater density
