Approach
The Smarter
Better connected systems mean faster
turnaround and increased throughput,
improved safety and lower operating costs.
Connecting decades of experience with a new, smarter
approach to port and terminal equipment optimization,
Trelleborg’s marine systems operation helps ports and
terminals deploy smart, engineered solutions for port
approach, berthing, docking and mooring. This enables
better informed real-time and strategic decision making,
both onshore and on board the vessel.
From port owners and operators to consulting engineers,
Trelleborg works with customers to determine best fit
solutions for specific applications, and supply a fully
integrated solution. End-to-end service and a
comprehensive product portfolio meet and exceed
customer needs, enhancing safety and improving
efficiency in all marine environments, from conception to
completion and beyond.

Parallel Motion
Fender System
Parallel Motion Fender System keeps the panel vertical at all times – irrespective of where the impact loads
are applied – but simultaneously allows the panel to rotate on plan to accommodate large berthing angles.
Parallel Motion Fenders can absorb the full design energy irrespective of impact level.
As Parallel Motion Fenders are mostly pre-assembled in the factory, installation is simple and fast.
Maintenance is minimal too – contributing to the low service life cost of Parallel Motion technology.

Shown here are two Super Cones mounted in a
back-to-back ‘Twin-Series’ configuration.
2Closed box panel (frame)
Fully sealed, pressure tested design. Shown with
optional lead-in bevels which are designed to suit
each case.
3Torsion tube and arm assembly
Also closed-box construction, the tube and arms
keep the panel vertical whatever level impact loads
are applied.
4Hinge units
The maintenance-free stainless steel pins and
bearings allow free rotation to accommodate berthing
angles, also eliminating moments in the hinge pin.
5UHMW-PE face pads
Trelleborg ‘Double Sintered’ UHMW-PE face pads
are standard to minimize friction and maximize
service intervals.
6Check chains (optional)
Check chains act as rope deflectors to stop ropes
from snagging, and to help with some large
angle berthings.
7Pile jackets (optional)
Purpose designed for every project, pile jackets are
factory built for a perfect fit to the fender onsite.
They can strengthen the structure and double as a
corrosion barrier in the vulnerable splash zone.
Jackets are also available for monopile systems.

Handling
MATERIALS / CONSUMABLES REQUIRED INFORMATION
Timber / rubber blocks
After unloading, all the equipment must be placed on
timber / rubber blocks to avoid damage to the plastic
or painted surfaces.
EQUIPMENT REQUIRED INFORMATION
Crane Refer to the General Arrangement drawing for the total
weight of the equipment.
Rigging equipment with spreader beam Refer to the General Arrangement drawing for the total
weight of the equipment.
❙ Unwrap the plastic packaging of the PMF unit with
necessary tools
Caution
The unwrapping operation must be performed on
the truck trailer so that the lifting points are
exposed. Lifting point locations and sizes are subject
to change based on the project requirement. Refer
to the General Arrangement drawing for details.
❙ A Spreader beam of suitable length & load rating
must be used to lift the PMF unit from the truck
trailer.
Recommendation
In the event of non-availability of a spreader beam,
two separate lifting hooks can be used.
Caution
❙ Lifting rope angles must be set in a way that they
do not scrape off any painted surfaces. Paint
damage while lifting is not covered under warranty
& the damages must be repaired.
❙ Do not walk under suspended loads.the General
Arrangement drawing for details.

Storage
At all times, all equipment must be stored properly to avoid any damage, environmental damage or damage
occurring from nearby moving equipment.

12
Storage
PROCEDURES
❙ Timber / rubber blocks must be placed on a dry
surface and the PMF unit should be carefully
placed on the blocks.
❙ After successful placement of the PMF unit, cover
it with a waterproof plastic tarpaulin to protect it
from dust, direct sunlight and ambient moisture.
Recommendations
❙ Use medium-duty tarp with an approximate
thickness of 0.007 - 0.008 in (0.18 - 0.20 mm).
❙ For long-term storage (>6 months), use heavy-duty
tarp with an approximate thickness of 0.011 –
0.012 in (0.28–0.30 mm)
❙ The tarpaulin must be tightly bound using nylon
straps, making sure that there are no exposed
areas.
Caution
Do not place any equipment, tools or furniture over
the covered PMF unit.
MATERIALS / CONSUMABLES REQUIRED INFORMATION
Timber / rubber blocks
All equipment must be placed on timber / rubber
blocks to avoid damage to plastic or painted
surfaces.

2.1.1 SCN fenders to Steel Panel
Assembling SCN fenders
❙ Fix the ”first” fender on the spool.
❙ Align the Sandwich plate as shown on the image.
❙ Lower the ”second” fender on the Sandwich plate
such that the bolt holes are aligned.
❙ Insert and torque the bolts.
Recommendations
❙ After inserting the bolts, only turn enough to
ensure the threads are engaged and in line. Once
all bolts are loosely inserted and the holes are
aligned, tightening may be commenced. Firmly
fasten all bolts and then torque down, ensuring
that adjacent bolts are not tightened in sequence.
❙ For fastening to rubber, torque values from
Appendix A should be used.
❙ Standard bolt torque values should be used when
fastening to steel.
❙ Refer to MN-I&M-RUB-SCN&SCK-v1.0- EN, 2017
for fender lifting methods.
Caution
The “first” and “second” fenders must be identified
based on their grades prior to the commencement
of installation. Refer to the General Arrangement
drawing.
