PsG PARALLEL MOTION FENDER is a uniquely designed complete fender system. A swivel lever-arm is placed between the structure, could be concrete or steel, and the front panel. The panel movement during the continuous fender compression, allowing it to move only parallel to its mounting irrespective of the impact level and angle.
The advantage of PM fenders (parallell motion fender)is the system provides identical energy absorption capacity at any impact level. The reaction force is much lower in comparison with the conventional fender systems and the lower reaction force result in less hull pressure and lighter structures, which can lead to significant savings in a complete project.
Last but not least, installation takes place above water and the fender system is lifted into place in one swipe and you get away from chain arrangements.
The panels can be adapted for a number of different rubber elements such as PsG LE elements, PsG cell fender PsG cone fender etc.
” Portsuppliers Group has delivered pilot fendersystem with rubber cone fender PSG-C 1000, where the challenge was to adapt to a existing pivot fender system ”
The PsG Pivot Fender can cope with large horizontal and vertical working loads, and offer very high energy absorption and low reaction. The fender is fixed in a box at the bottom or sheetpile quay, which holds the panel vertical on impact. Pivot systems are often interlinked to form flexible barriers along quay faces or around curved marine structures. Suitable for high tidals.
- The Pivot Fender requires less concrete work above quay, “lectern casting”
- Usually it is enough to attach the rubber fenders directly into the quay wall
- No moving parts
” Portsuppliers Group resilient Roller Fender is now mounted and rolling on”
Cushion Roller Fender are above all usued to guide floating structures and pontoons up and down piles gently and quietly. The picture shows a typical way of using the cushion rollers against the piles. To withstand berthing impacts, the roller cushion can be supplemented by a rubber cushion pad, see pad behind the roller fender.
Port of Trelleborg has two new Ferry locations and Portsuppliers Group has designed and delivered the Marine Fender Systems to both.
The choice of Fender Systems at location FL13 was closed panels with UHMW-PE face
pads and PsG LE Rubber Elements along with chain system. In the location FL14 the choice fell on PsG Arch Fender. Mooring PsG Tee Head Bollards on both locations.
Since the end of January the new LE-V fender system is mounted and ready to use for the new Lifeboat Institution in Falsterbo.
A cold January day the raft was ready to use for mounting the fenders. The choice of marine fender system was LE-V fender, which has two rubber legs mounted with a shield of UHMW-PE. The rubber leg for optimal energy absorption and the low friction shield to glide on. As there are tide difference in the Falsterbo channel it is important that the boat can glide sufficient when moored.
Now we wish them good luck! If you are interested in Lifeboat Institution you can read more for example on Royal Nation Lifeboat Institution – Saving Lives at Sea.
PsG steel panels are designed for optimal strength. Most often, the focus lays on rubber fender elements, but at high forces, the steel panel is as important as the rubber units on high-performance fender systems, this because the fender panels distribute reaction forces throughout the panel and give low hull pressure on vessel. The panel design may withstand large tidal variations and line loads. Another advantage of distributing the forces is that the panels can be designed for interconnection. For more secure mounting, the panels are designed with chains. PsG steel panels are designed either as open panels or often as closed box systems. With closed box systems, the panel is always airtight pressure controlled. Corrosion protection is provided by color systems with high durability in C5M class. The panels can be adapted for a variety of rubber elements PsG LE elements, PsG cell fenders PsG cone fenders etc.
Sometimes solutions need to fulfill several aspects. In winter when snow and ice usually keep the working boats busy just to have the mooring fairway free from ice, they cannot go too close to the usual fender system in case of getting stucked and in worste case destroy a fully good functinal fender system. With the PsG continuos fender wall you do not have the issue to get stucked in the fender system as the whole wall is covered with UHMW-PE pads. Behind you still have the LE-V rubber element to absorb the energy and have the right reactionforce for your berthing ship. This will work even with different ships as you can add vertical LE V fendersystem to fit other heights.
Our SAN Arch Fenders are particularly useful for vessels with high allowable hull pressures and for locations where mounting space is limited. It is reliable for a wide variety of berths even under the most severe conditions. This robust rubber fender from Portsuppliers Group can be equipped with an additional embedded steel plate. This allows the installation of a low friction PE-rubbing plate, a steel fender panel or the mounting of the fender unit behind a pile construction.
Key performance characteristics include:
Good energy absorption and low reaction force.
With shockproof plates at the front, it may reduce surface pressure.
Pro-longed life and easy replacement.
Excellent shear resistance.
Portsuppliers Group is specialized in safe berthing and mooring of vessels within harbours and ports as well as waterways and offshore structures.
PsG Donut Fenders are engineered to be installed over monopiles to provide free vertical and radial movement to ensure maximum protection. With high energy absorption and low maintenance the PsG Donut Fender can be used effectively for dock and port entrances and bridge supports.
The construction reminds of a foam-filled fender with a polyurethane elastomer skin and a cross-linked closed cell thermolaminated polyethylene foam core. The central tube has wear pads with UHMW-PE for excellent lowfriction.
The PsG Donut Fender will be sized to fit its purpose, they are unsinkable and can be finished in a variety of colors.
When it comes to installation the fender has to be lifted and lowered onto the fender pile and then ready for use!
