Fendering
We bring the benefit of significant marine and operational expertise to all
our fender customers, working with them to ensure that they obtain the
best-fit, best value product to suit their fendering needs. The business of
Fendercare Marine was built on our ability to provide best in class fendering
solutions to our clients. We are not just a trading house, looking to sell
fenders on with a margin – we are also, via our ship-to-ship transfer division,
the world’s largest operator of genuine Yokohama-brand pneumatic
fenders. To put it simply, we wouldn’t stake our STS reputation on any other
brand of pneumatic fender.
These fenders are ideal for short-term port calls or one-off berthings;
interim fendering during construction or maintenance work; transfer
of cargoes at sea; buoyancy aids; providing vessel stand-off or
double berthing requirements. Additional fenders are provided to
naval specifications.
Our through-life support package involves not only swift and efficient
sale of new fenders, but also rental, hire purchase and repair/refurbishment
services. Highly trained staff at each of the bases in our global network are
able either to receive your damaged fenders for repair at our premises or to
travel to your site to undertake repair or refurbishment work on pneumatic
or foam filled fenders.
In addition to Yokohama floating fenders, we are now able to offer our
own brand of Hippo floating foam fenders along with a broad range of fixed
fenders and vessel fendering systems.
Our portfolio of fendering solutions can be summarised as:
Yokohama pneumatic and hydro-pneumatic fenders
Hippo floating foam fenders and donut fenders
multi-purpose fenders – for dockside or vessel-side installation
Hippo vessel fendering systems
fixed fendering systems
bespoke solutions
We would encourage you to not just think of us as a supplier of fenders,
but as a support resource upon whom you can call for guidance as to
the best and most innovative solutions to your fendering requirements.

Yokohama Floating Fenders –
Pneumatic 50/80
Yokohama began manufacturing floating pneumatic fenders in 1958.
Since then, more than 60,000 Yokohama fenders have been supplied into
ship-to-quay and ship-to-ship applications worldwide. Put quite simply,
over the course of the past half-century more people have put their faith
in Yokohama fenders than in any other brand of pneumatic fender.
And that faith has been justified by the durability and longevity of the
fenders – providing an outstanding return on the investment which their
owners have made in them.
ISO 17357 is now firmly established within the marine industry as the
international standard for the manufacture, testing and performance of
pneumatic rubber fenders.
Over the years Fendercare Marine has discovered that although other
manufacturers may be claiming full compliance to ISO 17357, it can be
demonstrated that in certain cases irregularities have been found where
fenders that have been supplied as compliant do not in fact comply with
the standard in one or more of the following criteria:
incomplete material tests
hydrostatic pressure test wrongly conducted or failed
incorrect evaluation of angular and durability tests
incorrect reinforcement material used
rubber specifications not meeting ISO 17357 requirements
certificates out of date or non-existent
Drawings and picture references are for illustration purposes only.

Yokohama can demonstrate compliance to PIANC 2002 for floating
pneumatic fenders. Further information can be supplied on request.
Advantages
Safe for excess load
The reaction force of a floating pneumatic fender does not increase sharply
even under excess load. Therefore, these fenders perform extremely well
under such conditions and, as a result, protect ships and mooring facilities.
No deterioration or variation in performance
Because pneumatic fenders use the compressive elasticity of air, there
is no performance deterioration due to fatigue. The performance of
these fenders remains unchanged at extremely low temperatures,
even below -50°C.
Safety and reliability
Yokohama pneumatic rubber fenders are constructed using several layers
of strong tyre cord and are therefore extremely resistant to pressure and
cutting. The larger sizes (2.5m dia upward) are fitted with a safety valve to
prevent accidents in the event of over compression.
Construction
The fender body is constructed of an inner rubber layer, reinforcing cord
layers and an outer rubber layer. All of these layers are vulcanised together
and then proven by hydraulic pressure test.
The outer skin rubber compound is designed and manufactured to be
able to withstand both strenuous use including abrasion during adverse
weather conditions whilst protecting the cord layers and inner rubber.
The synthetic tyre cord layers are arranged at optimum angles designed
to distribute load and stress evenly. The inner rubber compound is
designed to be completely airtight, utilising a compound equivalent to
that of an inner tube of a car tyre.
To provide maximum strength and safety, the outer skin of a
hydro-pneumatic fender is thicker than a normal surface fender.

Simple and low cost installation
The weight of the fender is supported by the water on which it floats.
Fenders can, therefore, be moored simply by means of a guy rope or chain
at minimal cost. They can be removed easily to another position when not
in use and transferred to alternative mooring points as required.
Chain and tyre net
In the vast majority of cases, a chain and tyre net will be fitted to a
pneumatic fender to protect the body from damage by sharp objects or via
the absorption of sheer loads during berthing. The better the net, the more
protection it will offer.
From experience in using these fenders ourselves, we have developed a
unique high protection net system which offers more protection to the
body of the fender than any other net available in the market today –
thereby potentially extending the life of the fender.

Floating Fenders
We have the widest possible experience of the varying needs of a protective
net and offer a range to meet all needs:
lightweight nets to meet ship’s crane and davit limitations
heavy duty nets to cope with harsh sea conditions and high snatch loads
double nets to offer stand-off options
non-marking tyre nets for navy and cruise ship applications
rope nets for ultra lightweight applications
stainless steel nets for non-magnetic requirements
All Fendercare Marine nets are designed with ease of maintenance in
mind. The net is built in sections so it remains easy and cost effective
to repair, should a specific area of the net sustain damage.
Identification
Each fender has the following markings:
identification requirements
international standard number and applicable year
size (diameter and length)
initial internal pressure
date of manufacture
name of manufacturer
individual serial number
type of reinforcement layer
RFID tagging system
Radio Frequency Identification (RFID) is now fitted to all Yokohama fenders.
A tag is buried in both ends of the fender enabling easy reading however
they are positioned. This RFID tag was introduced so you can identify the
individual fender should the standard markings become unreadable.
It will also assist in the maintenance of records and inventories over the
long-term.
Fendercare Marine are able to supply the RFID Tagging Reader as an
optional extra. This reader can read all RFID tags mounted on fenders
manufactured to this specification.
Fendercare Marine also maintains a database of all Yokohama fenders that
are sold worldwide and can therefore assist in returning fenders to their
rightful owners, should they become lost or stolen.
Certification
Each fender is supplied with a certificate, detailing the following:
material for rubber and fitting metal
satisfactory results of tests
record of compression test
dimension and weight
record of serial number and RFID tag number

Floating Fenders
Hippo Floating Foam Fenders
Our in-house Hippo brand, manufactured in the UK, is one of the world’s
leading designers and manufacturers of floating foam fenders.
The use of memory foams for the fender core, which have high compressive
strengths, results in an ability to absorb a great deal of energy during
operation. This is complemented by low reaction forces, making berthing
operations easier – especially in difficult conditions.
Users also gain peace of mind from knowing that the closed cell
structure of the foams used by Hippo means that these fenders are
virtually unsinkable and will keep functioning – even if damaged
beyond viable repair.
Although fitted as standard with highly durable nylon reinforcement to
the outer skin, we are now uniquely able to offer Kevlar™ reinforcement
systems to those customers seeking the highest possible level of protection
from in-service damage and therefore, the best possible return on
their investment.
One other feature worthy of mention is the simple yet unique internal
structure of the fenders which allows the shear loads to be absorbed by a
through-chain arrangement terminating in end-shackles rather than the
body of the fender itself. This has been engineered so that in the event of
overload, any damaged components of this system can be replaced in
isolation – as opposed to other foam fenders where the end-fittings form an
integral part of the internal workings of the fender and which, if damaged
by shear forces, can lead to the fender being written off.
Key features of Hippo fenders
High energy absorption/low reaction force
Virtually unsinkable
Simple, effective internal engineering
Low maintenance costs
Easy installation
Non-marking PU elastomer skin
Optional Kevlar™ reinforcement
Available with best in class Fendercare Marine chain and tyre nets
Standard range supplemented by bespoke design service
Typically Hippo floating fenders would be supplied as cylindrical units,
but due to our flexible manufacturing processes and our commitment to
offering best possible assistance to our customers, we have also supplied
spherical, rectangular and cog-type fenders.

Hippo Floating Donut Fenders
Hippo Marine has been manufacturing and supplying donut fenders for
well over a decade.
Donut fenders are, very simply, a donut shaped type of foam filled floating
fender which are designed to slip over a stationary monopile. They have
also been supplied into other applications, such as protecting jack-up legs.
The principle of such fenders is that they float up and down with the tide
therefore ensuring optimum protection at all times. They are also designed
to freely rotate around the pile to allow vessels to slide along them into the
required position – making them ideal for applications such as lock and dry
dock entrances and protecting bridge supports.
Main advantages of donut fenders
igh energy absorption/low reaction force compared to bucking type
H
rubber fender
Low shear forces as the fender rotates, combined with low-friction skin
Self-adjusts with the water level to always be in the correct position
Quick and easy to install – simply slipped over a pile
Low ongoing maintenance requirements

Actual values for these sizes may vary ±15%. These stated performances are per metre of donut height.
Fender performance is engineered at 60% foam compression. The deflection of the monopile itself will
provide additional energy absorption with the same reaction force rating. Due to the way in which these fenders are made, an almost infinite number of combinations of sizes and
specifications are achievable. The above grid represents the most commonly requested cylindrical Hippo
donut fenders we are asked to quote and supply, but is by no means an exhaustive list of what we can
supply. Please contact us if you cannot find the fender size, type or performance which you require in the
above table.

Floating Fenders
Floating Pneumatic
Submarine Fenders
In order to provide full protection at surface and subsurface, Yokohama
pneumatic submarine fenders are deployed vertically. To maintain their
position, the fenders are water ballasted and also have a counterweight
attached to the bottom of the fender. The weight, shape and method
of deployment of the counterweight can be adjusted to suit individual
situations.
Fendercare Marine has supplied Yokohama submarine fenders to many
navies around the world, including Australia, Brazil, Canada, Greece, Japan,
the United Kingdom and the USA.
Advantages
The Yokohama submarine fender was launched in 1984, since then it has
been extensively used by navies across the world. Advantages of fenders
over alternative, traditional berthing methods include:
use as a cost effective replacement for deep water catamarans
easily moved to provide flexibility in berthing
easily transported to provide emergency berthing facilities
maintenance requirement almost non-existent
unaffected by extreme climatic conditions
Fender dimensions and weight
Submarine fenders are available in the following standard sizes and
pressures, offering a fender system to cope with all designs of submarine,
from the smallest conventional submarine to the largest nuclear submarine
in service today.

Submarine fenders are designed to offer higher bursting strength than a
normal surface fender, the minimum burst pressures are:
2000mm diameter and smaller = 4.9kgf/cm2
2500mm diameter and larger = 5.7kgf/cm2
To facilitate water charge and discharge, flange openings are sited at
each end of the fender. In addition, submarine fenders are fitted with
a safety valve to enable excess pressure to be released, should over
compression occur.

Naval Lightweight Grey Fenders
The naval lightweight grey fender was developed by Fendercare Marine
in co-operation with The Yokohama Rubber Company in Japan following
extensive trials and input from the UK Royal Navy.
The fender was designed to meet the following requirements:
weight constraints
male/female manageability
high level of performance
ease of storage
long life expectancy
non-marking/non-magnetic
Fendercare Marine has supplied Yokohama onboard fenders to many
navies around the world, including Bangladesh, Belgium, Canada,
Germany, Greece, Ireland, Jordan, Malaysia, Norway, Oman, South Africa,
the United Kingdom and the USA.
In the past 10 years we have supplied the UK Royal Navy with over
2000 fenders. This represents approximately 180 complete ship sets.

Construction
The fender body is constructed from a rubber inner core with a non
magnetic metal mouthpiece at both ends. A grey rubber outer skin with a
minimum of two plies of tyre cord layers, also coated with rubber, protects
the inner core. The fenders can therefore be used on mine
counter-measure vessels.

Floating Fenders
A PT1/8 air valve is fitted at the end of the fender to allow access for
inflation whilst ensuring maximum protection from damage during
normal use.
Application
Vessels carry the fenders onboard with them at all times, for use both
at home, at sea and in foreign ports as utility fenders. The fenders are
used primarily for two applications – ship-to-quay and ship-to-ship. For
ship-to-quay application the fenders are used to berth a vessel alongside a
quay or wharf. For ship-to-ship application the fenders are used to berth or
moor two vessels side by side (double-banking) in port or at sea.
There are three main configurations for fender grouping when in use:
Three single eye
arrangement
Three double eye
arrangement
One double eye/two
single eye arrangement
Mooring positions of the fender groups on the ship should keep the ship
separated and stable at the same distance from the quay or another ship
all along the parallel mid-body.
Berthing against a quay or a stable ship moored in port is straightforward
but the following should be considered when confirming fender size: (1) the
approaching ship’s docking speed, (2) approaching angle, (3) hull shape,
(4) protrusion from ship and (5) equipment fitted on the hull.
It should be carefully noted that required stand-off distance is an important
variable to consider when berthing. For example, if a vessel is light in weight
but requires a stand-off of 2 metres (due to large flare or parts/equipment
standing proud of the hull such as a stabiliser) then larger fenders would
be required.

similar size in more stable or
