1 INTRODUCTION
This manual has been prepared to familiarize you with the specifications and
procedures for operation, installation, maintenance, inspection, testing and
repair of NOREQ Pneumatic Rubber Fenders, We hope that the manual will be
useful and convenient so that you can use our fenders safely and satisfactorily.
The main features of NOREQ Pneumatic Rubber Fenders are;
1) High energy absorption and low reaction force and surface pressure.
2) No decline in the rate of energy absorption when obliquely compressed, under normal
circumstances, and uniform surface pressure for any contact area.
3) Low reaction force to prevent damage from repeated impacts against the hull of a ship,
jetty, or a mooring rope.
4) Ability to float and thus rise and fall with the ebb and flow of tides and the movements of
a ship.
5) Easy installation.
6) High standard of uniform quality in compression performance with no deterioration of the
rubber.
2 SPECIAL PRECAUTION
This product is containing compressed air inside. If the product bursts, energy
of the compressed air could cause damage to people or environment.
Therefore,
1) Make sure that air pressure is not more than specified pressure, as there is a possibility
of burst if the air pressure is higher than the specified pressure.
2) Make sure that there are no damage on the product as the damage will weaken
pressure resistance strength of the product and make the product burst.
3) Use within the maximum energy absorption specification in Table 3-1/3-2 to avoid
rupturing the fender.
4) Avoid allowing the fender to come in contact with surface protrusions or sharp-edged
implements at anytime.
5) Cut or exposed reinforcement cords might result in damage to the fender.
6) The fender must be lifted at its designated lifting points. Failure to do so could result in
damage to the fender.

INFLATION
CAUTION: Overinflating is very dangerous, Therefore, Please follow the
procedures below very closely.
1) Remove the cap from the air valve at the flange opening and press the top of the
air chuck at the end of the pressure gauge onto the valve of the fender to
measure the air pressure and to see if additional air is necessary.
2) Connect the air hose to the compressor.
3) Turn on the compressor and open the compressor valve. The pressure of the
compressor should be between 4 to 7 Kgf/cm2 .
4) Press the air chuck at the end of the air hose onto the valve and air will
automatically fill the fender.
5) Before reaching the specified pressure, periodically check the air pressure in the
fender to avoid overinflating. To make these checks remove the air chuck being
used for inflation and apply the air chuck of the pressure gauge in the same
manner as described in the above 1).
6) Stop inflating the fender at the specified air pressure plus an additional 0.05
Kgf/cm2 .
7) Close the compressor valve.
8) Use soapy water to check for leaks from the valve or the flange opening.
9) Air from the compressor will have a high temperature but will decrease in
temperature after inflating the fender. Therefore, check the pressure again one
hour after inflating the fender. Lastly, check the pressure again once the fender is
floating on the water.
10) If the pressure is too high, release the air by pushing the head of the valve core.
11) Finally, close the valve cap firmly. Store the air hose without folding it tightly.
6
UNPACKING
6-1. Packed and deflated
Unpack the fender and inflate it.
1) Cut all wire ropes or steel bands wrapped around the fender.
CAUTION: The ropes or bands may recoil with great force when cut.
2) Inflate the fender after clearing the area in order that the surface of the fender is
not damaged with sharp protrusions or points. Inflate the fender slowly to avoid
tangling the net.
6-2. Containerized and deflated
Unpack the fender and inflate it.
1) Life the fender from the container using a bar.
2) Place the fender on the desired surface area in the same condition as it was loaded
in the container.
3) Cut the wire ropes surrounding the fender.
CAUTION: The wires may recoil with great force when cut.
4) Before inflating the fender, make sure that the flange opening, the ends of the
fender, and the net are in the correct position, so that the net will not slip during
inflation.
5) Remove all cut wires, and inflate the fender slowly to prevent tangling of the net.

7 INSTALLATION
7-1. For a Pier / jetty
Refer to Fig. 6-1 and 6-2 and the following points.
1) Remove all protrusions such as frame books and steel framework to make the pier
wall as flat and smooth as possible.
2) Construct the pier wall as flat as possible to avoid deforming the fender
(unreasonably). If special characteristics of the pier prevent this, please contact us
for proper installation.
3) At both dolphins and ordinary piers/jetties, it is desirable to put the mooring
position(anchor position) more than three meters away from the fender.
4) The guy rope or chain securing the fender should have some “play” to
accommodate the ebb and flow of the tide.
5) When installing a fender at an ordinary pier/jetty, at least two fenders must come in
contact with the parallel body of the ship, one at each end of the parallel section.
7-2. For a ship
1) When the fender is floating, the guy rope or chain should be long enough to avoid
sudden stress on the guy ropes or chains.
2) Attach the guy ropes to a secure part of the ship such as a bollard. Avoid weaker
parts such as handrails etc.
3) It is desirable to use a crane, derrick or davit to hang the fenders. For information
about NoreqFender Davit, please see www.noreqfender.no or contact us.
4) Install the fenders away from scuppers and other protrusions.
5) When two ships are moored side by side, at least two fenders must come in contact
with the parallel bodies of each ship, one at each end.
6) When waves are high or the contact area cannot be fixed, avoid rigging in a
continuous string. Instead, place them at individual points along the ship’s hull.
7) The guy lines should be sufficiently long to allow for tidal variations.

8 PRECAUTIONS
1) Make sure the fender’s air pressure is correct.
2) Keep within the fender’s maximum energy absorption limits (ref. 3-1/3-2). The
energy the fender must absorb depends on the speed of the vessel approaching for
berthing and its weight. Please observe these factors when berthing in order to
utilize the maximum energy absorption characteristics of the fender.
3) It is advisable to adopt specific berthing procedures for each type of vessel and port
in order not to exceed the fender’s maximum energy absorption limits.
4) Avoid contact with sharp protrusions when berthing.
5) When the vessel is mooring, do not drop anything sharp edge or pointed object
onto the fender.
6) Special care should be taken in berthing for a ship having smaller free board than
the top of the fender.
7) Avoid securing the ship’s hawsers too tightly during offloading to prevent the
fenders from rolling up the face of the pier. Loosen the ropes to ensure that the fenders
are floating.
8) When two or more fenders are used, periodical rotation of the fender is
recommended to lengthen their service life.
9) When mooring, make sure that the parallel body of the ship’s hull comes in contact
with at least two fenders.
10) Oblique compression to the fenders should be limited max. ten degree when
13
berthing.
11) Avoid moving the ship while the fenders are under strong compression.
12) Do not use fenders in extremely rough water.
9 INSPECTION AND MAINTENANCE
1) Check the air pressure of each fender at least once a year and, if possible, more
frequently. If you make a spot check with your hand and the pressure seems less
than normal, perform a gauge check referring to the description in 4-1 of this
manual. If additional air is needed, fill the fender according the specifications show
in Table 2-1. If the pressure is low, even considering the temperature factor, air
might be leaking from the fender. In this case, check for leaks around the flange
openings using soapy water. An air-leakage test should be done by making a gauge
check of the specified pressure and repeating the check twenty-four hours later to
determine if the pressure has dropped or not.
2) If there is a cut or worn part on the fender’s surface, repair according to the
procedures given in Section 10 of this manual.
3) When the metal fittings on the fender become rusty, remove the rust and coat the
fittings with rustproof paint.
4) Check the net and guys for rust and wear. Check the shackles for loss of pins, and
the swivels to see if they are properly greased. Repair or replace accordingly.
5) Remove all protrusions from the pier-jetty wall and check periodically for any new
protrusions that might appear.
6) Check all anchors for wear and tear, and repair when necessary.
7) Remove all sea moss or other marine life that has attached itself to the fender.
8) To ensure proper rotation of the swivels, apply grease when necessary.
9) Inspect and clean the safety valve every second year.
10 REPLACEMENT
If one of the following conditions applies to your fenders, have them
replaced.

further use of the fender appears to be dangerous.
SAFETY VALVE
The safety valve for the pneumatic rubber fender is specially designed to function in
emergencies. If the internal air pressure of the fender goes up too rapidly, the safety
valve will release the pressure and prevent the fender from bursting. Although the
fender has a safety valve, this does not mean that it is safe to compress the fender
beyond its maximum energy absorption capability.
12
REPAIR
The materials and instruments in the accessory box are available only for temporary
repair of a fender. The best method for complete repair is vulcanization by a rubber
company.
The NoreqFender Repair Kit contains the following:
Pressure gauge, hose, nipple and rubber sheet. Adhesive is not included in repair kits.
14
Please obtain “TIP TOP SC2000” locally for adhesive.
1) If a fender’s surface rubber is cut or peeled enough to expose the reinforcement
cord layer use the following five steps to repair it.
a) Buff the damaged rubber and a 100mm radius area around it immediately with
sandpaper. Do not buff the exposed reinforcement cord. Please clean the
exposed rubber, the buffed area and the exposed reinforcement cord with a
solvent such as gasoline.
b) Mix TIP TOP Cement SC2000 and 10% RF hardener, and apply one coat of the
mixture onto buffed area. Allow this coat to dry completely until no longer tacky
on back of finger.
c) After that, apply a second coat of the cement to the same area.
d) Cut a rubber patch roughly the same size of the buffed area and taper the
edges. When the second application of cement has dried sufficiently, apply the
patch over it.
e) Use the hand roller provided in order to roll the patch onto the prepared
surface, beginning from the center of the patch and working toward the edges
to ensure that no air is between the patch and the surface rubber.
2) If the fender appears to be leaking, use the following steps to find and repair the
leak.
a) Check the point of the leak by applying soapy water to the surface of the fender.
b) Buff a 100-150mm radius area immediately around the hole with sandpaper,
and clean the area with a solvent such as gasoline.
c) Mix TIP TOP Cement SC2000 and 10% RF hardener together thoroughly.
d) Hole the rubber plug with the jig as shown in the following figure, and after
dipping the plug into the mixed cement, insert it into the hole.
e) Pull out the jig, leaving only the plug in the hole. Check the leak again, and if it
is still leaking air, insert one or more plugs into the hole until the leaking stops.
f) After the leak has been plugged completely, cut the plug(s) flush with the top of
the surface rubber layer of the fender.
g) Wash the buffed area with a solvent again, and apply the cement mixture.
