Description
10
void, which is open at the ends of the fender. This may lead to build up of pressure
inside the fender at berthing, due to possible assembly of water and ice inside the
fender. Such build up of pressure may lead to damages both to the fender system and
the vessel. If water or ice is assembled inside a fender the absorbing characteristics of
the fender will be affected in that it will make the fender stiffer.
Summa
In view of the above it is beneficial if the downtime of a quay can be
shortened.
The present invention is based on the idea of providing a modular fender
system. By means of the modular fender system of the present invention, it is relatively
easy to replace broken parts if needed, to exchange fenders depending on the vessel to
be received at the dock. The fenders of the fender system are formed of a number of
fender sections or modules. Handling is facilitated in that fender sections are used,
having a relatively low weight compared to the fenders usually used today, which are in
one piece.
By means of the fender sections it is not necessary to replace a complete fender
if only a part of the fender is broken.
By making the shields of material of a low weight, such as aluminium,
composite material, plastic or a combination of these materials, handling of the shields
is facilitated. It is at least facilitated compared to previous shields norrnally having parts
made of a steel structure. By making the shields in the form of modules it is possible to
replace only parts of a shield, if needed. The modules also make it fairly easy to adjust
the dimensions of the shield both in length and width.
Further objects and advantages of the present invention will be obvious to a
person skilled in the art when reading the detailed description below of embodiments of
the invention.

Detailed Description
The fender system of the present invention is shown fastened at a quay wall 1.
The fender system comprises at least one fender 2 and at least one shield. The at least
one shield has one or more plates 3, placed on a panel 4, which panel 4 is fastened to the
at least one fender 2. Normally, a number of plates 3 are placed on the panel 4. The
number of fenders 2 used depends on the size of the frame 4 and also on the size of the
vessels to be received by the fender system.
Each fender 2 is formed of four fender sections 5, 6 or modules in the shown
embodiment. Each formed fender 2 has the form of a truncated cone, which has an open
through space in the centre. The fender sections 5, 6 forrning one fender 2 are identical
and each is forming a quarter of the fender 2. The fender sections 5, 6 have two ?anges
7, 8 at opposite ends of a wall. The ?anges 7, 8 have a curvature form. The ?ange 7 at
one end of the formed fender 2 has a larger outer diameter than the flange 8 at the other
end of the formed fender 2. The ?ange 7 of the fender 2 having the larger diameter is to
be facing the quay wall 1.
The fender sections 5, 6 are held together by means of a number of connecting
pieces 9. Said connecting pieces 9 are received in recesses 12 in the ?anges 7, 8. Each
connecting piece 9 has a curved shape, following the curvature of the ?anges 7, 8 of the
fender sections 5, 6, and with through holes 16 at opposite ends. Each connecting piece
9 is to bridge two fender sections 5, 6, whereby it is fastened to respective fender
section 5, 6 by means of screws received in the through holes 16. The through holes 16
of the connecting piece 9 are placed in line with through holes 18 in the recesses 12 of
the ?anges 7, 8. The screws received in the through holes 16 of the connecting pieces 9
are also going through the through holes 18 of the recesses 12. Thus, the function of
said screws is both to connect fender sections 5, 6 and to fastened the fender sections 5,
6 to the quay 1. An integrated boss 15 of the connecting piece 9 is placed in the middle
and protruding at one side. Said boss 15 of the connection piece 9 is to go down
between the fender sections 5, 6. The holes 18 of the fender sections 5, 6 and the holes
16 of the connecting pieces 9 are placed to give a gap 13 between adjacent fender
sections. The boss 15 of each connecting piece 9 will assist in keeping the gap 13
between adjacent fender sections 5, 6. The gaps 13 will hinder water from
accumulating inside the formed fender 2. Water trapped inside a fender will also affect
the absorbing characteristic of the fender. Water trapped inside the fender is a
disadvantage to the load-de?ection curve of the fender, as it will make the fender stiffer.
Washers 11 are placed in recesses 14 in the ?anges 7, 8. The washers 11 have
through holes 17, which holes 17 are placed in line with through holes in the ?anges 7,
8. The fenders 2 will be fastened to the quay wall 1 and panel 4, respectively, by means
of screws received in said holes of the washers 11 and the ?anges 7, 8, respectively.
Also the screws received in the through holes 16 of the connecting pieces 9 are used to
fasten the fenders 2 to the quay wall 1 and panel 4, respectively.
The fenders 2 may have different sizes. In the shown embodiment the fender
sections 5 can for example have a height of 600mm and the fender sections 6 can have a
height of 400mm. The height in this case is the distance the fenders 2 will protrude from
the quay wall 1. A person skilled in the art realizes that fender sections having other
heights may also be used. Two fenders 2 may be connected to each other end at end.
The fenders 2 are connected to each other with the ?anges 8 having the smaller
diameter facing each other. In connecting two fenders 2, an interrnediate ring 10 is
placed between the fenders 5, 6 and screws are received going through the holes 16 of
the connecting pieces 9 of respective fender 2 and the interrnediate ring 10. With fender
sections 5, 6 having a height of 600mm and 400m, the height of the fenders 2 may be
about 400mm, 600mm, 800mm, 1000mm or 1200mm, depending on whether one
fender 2 or two interconnected fenders 2 are used. In the stated examples of heights, the
thickness of the interrnediate ring 10 is not included in the height of two interconnected
fenders 2. The thickness of the intermediate ring 10 is only a small fraction of the total
height of two interconnected fenders 2. Irrespectively of the height of the fender
sections 5, 6 the different outer diameter of the ?anges 7, 8 are the same for the
different formed fenders 2. Thus, for fender sections 6 having a less height the
inclination of the truncated cone will be larger than for fender sections having a larger
height.
The fenders 2 may be made of material having different hardness. For example
the fender sections 5 having larger height may be made in a relatively soft material,
while the fender sections 6 having a smaller height may be made in a relatively hard
material. By varying the hardness of respective fender section 5, 6 and the load
distribution for the part between the ?anges 7, 8, it is possible to control the load-
displacement curve of the fender 2. It is also possible to vary the thickness of the walls
of the fender sections 5, 6 in order to control the load-displacement curve of the fender
2.
In use one or more fenders 2 are fastened to the quay wall 1. Either the four
fender sections 5, 6 are assembled to form each fender 2, before fastening it to the quay
wall 1, or one fender section 5, 6 is first fastened to the quay and then the other fender
sections 5, 6 are fastened to the quay wall 1 and adjacent fender sections 5, 6. If a
further fender 2 is to be attached to the first fender 2, it is also attached to the first
fender either as one unit or one fender section 5, 6 at the time. As indicated above an
interrnediate ring 10 is placed between the fenders 2, when assembling two fenders 2 to
one unit.
After having fastened the one or more fenders 2 to the quay wall 1, the shield 3
is attached to the one or more fenders 2. The shield is to face the side of the berthing
vessel. The size of the shield is dictated by the size, tonnage etc. of the vessel.
Thanks to the relative low weight of the different parts of the fender system,
there is no need for heavy machinery in handling the different parts. This facilitates
replacement of broken parts. The modularity of the fender system also facilitates
replacement of broken parts. If only one fender section 5, 6 of the frame system of the
present invention need to be replaced, only said fender section 5, 6 is removed while the
other fender sections 5, 6 of the fender 2 remain fastened to the quay wall 1. After
removal of the broken fender section 5, 6 a new fender section 5, 6 is fastened to the
quay wall 1 and adjacent fender sections 5, 6, respectively. Also the panels of the shield
3 may easily be replaced if needed. The panels may be needed to replace due to being
broken or losing the surface friction.
Depending on the expected load one or more fenders 2 are used to carry one
shield. If several fenders 2 are used they may be placed one above the other and/or side
by side with some distance between adjacent fenders 2. One example of an embodiment
having fenders 2 placed above each other is illustrated in Fig. 11.
Normally a number of fender systems are placed along the quay wall 1, in
order to be able to support vessels of different lengths.
In one embodiment the shield of the fender system is formed of a panel 4
carrying a plate 3. In Fig. 8 the panel 4 is shown. The panel 4 has a number of holes 19,
by means of which the plate 3 may be ?xed to the panel 4. The holes 19 are placed at
equal distance from each other on a circle. In Fig. 9 the plate 3 is shown. The plate 3 is
made of a plastic material in one embodiment. The plate 3 has a number of holes 20
placed to correspond with the holes 19 of the panel 4. Thus, the holes 20 of the plate 3
are placed at equal distance from each other on a circle. The plate 3 is fixed to the panel
4 by means of screws (not shown). The screw heads are received inside the holes 20 of
the plate 3. The plates 3 are to abut the vessel at berthing and are made of the same
plastic material that is commonly used today.
Each shield may have a number of plastic plates 3, to be facing the vessel. The plastic
plates 3 may have a standard dimension. Based on the choice of number of plastic plates
3 the dimensions of the panel 4 are decided. The modular build-up of the shield makes it
easy to replace parts of it, if needed. lt will nonnally not be necessary to replace the
entire shield.
