Chain and tire nets are designed to provide

a rugged exterior for the pneumatic fender

and increase protection against cutting or

puncturing.

Typically manufactured with used tires

these nets provide an ecologically friendly

use for this resource.

Chain nets provide long life against

corrosion.

Rubber sleeves are often fitted on the

chains between the tires for added

protection against scraping the ship’s hull.

The chains are attached to end rings to

connect the entire system.

Rubber moulded chain net tyre

harnessing provides extra advantage

when used under compression.

Rubber moulding provides extra

thickness of rubber sleeves to the chain

net tyre harnessing.

All these features render this to have

nearly zero maintenance.

1.4 HI-TECH SLING PNEUMATIC FENDERS (HPF-SB/HPF-SG)

HSPF Fenders are designed to use without chain net for

special applications like where metal contact due to chain

is not permissible.

Advantage of HSPF is that they are light in weight and do

not require maintenance of chain nets.

HSPF fenders have a thicker skin than normal HPF

Fenders which are protected by a chain and tire net. This

reduces their susceptibility to puncture. Also provided

longer life against abrasion.

HSPF are most widely used for naval applications, passenger vessels and where abrasion due

to the harnessing is not acceptable. Available in black/grey body.

1.5 HI-TECH RIBBED PNEUMATIC FENDER (HPF-SR)

1.7 HITECH FOAM FENDERS (HFF)

Foam filled fenders are preferred choice when

looking for a low maintenance and cost effective

fender system. These fenders provide high energy

absorption with relatively low reaction force.

Rope nets/Fibre nets and Rubber sleeve nets are

designed to provide a rugged exterior for the pneumatic

fender and increase protection against cutting or

puncturing.

The wire rope net is lighter than a chain net but is more

susceptible to corrosion.

The wire ropes are attached to end rings to connect the

entire system.

Rubber sleeves are normally fitted on the wire ropes between the tires for added protection

against scraping the ship’s hull and causing wear on the wire rope

Fiber net has a strong fiber bundle rather than a chain or wire rope to provide the strength

member.

Fiber net is recommended for applications where the risk of sparking (however minimal) must

be reduced such as for LNG terminals.

Fiber net is lighter than either chain or wire rope net is susceptible to cutting and abrasion.

3. HI-TECH NOVA CONE FENDERS (HNC)

The Hi-Tech Nova Cone fender was developed to meet the high energy absorption requirements of the

large cargo vessels which began appearing in the 1990s. Hi-Tech has been producing the HNC

element since 1994. In that time Hi-tech (Hi-Tech Elastomers Ltd.) has produced HNCs from very

small 300 mm high to very large 2000 mm high to meet the requirements of our customers.

The features of the HNC, dimensional stability which can perform in many situations, high deflection

capability which produces high energy absorption with low reaction and multiple rubber grades

allowing a wide range of performance characteristics, makes HNC an excellent fender element for a

wide variety of berthing situations.

HNC proved superiority in design against normal cone fender available in market because of having

larger hole on the top side and strip vent on the flange side which eliminates water/air catching within

the cone body under maximum deflection condition.

The HNC is normally mounted to a pier wall and commonly is connected to a steel panel fronted by

UHMW-PE pads which act as the contact area for the berthing vessel. The panel and pads provide a

surface with great wear resistance and strength providing long life for the fender system.

3.1 PARALLEL MOTION FENDERS The principle of the Parallel Motion Fender is to stabilize the fender

panel so that it remains vertical and deflects the energy absorbing

elements without the detrimental effects of angular compression.

This is accomplished by holding the fender panel by two torsion

arms with a hinge arrangement. Keeping the fender panel vertical

also prevents the panel from contacting a vessel’s super structure in

the case of a vessel contacting the panel below the center line of the

fender elements due to tidal conditions.

4 HI-TECH CELL FENDERS (HCF)

The Hi Tech Cell Fender (HCF) is a proven fender design. Originally developed over thirty years ago

the cell fender was engineered to the buckling of the rubber walls to absorb greater energy than could

be achieved with radial compression of cylindrical fenders. Hi-tech has produced the HCF line in

fenders ranging from 400 mm high weighing 75 kgs. to ones measuring 2250 mm high and weighing

7400 kgs.

The HCF is normally mounted to a pier wall and commonly is connected to a steel panel fronted by

UHMW-PE pads which act as the contact area for the berthing vessel. The panel and pads provide a

surface with great wear resistance and strength providing long life for the fender system.

5. HI-TECH “Z” TYPE FENDERS (HZF) The HZF LEG FENDER is a proven fender design. Originally developed over twenty five years ago the

leg fender was engineered to minimize the amount of rubber necessary for the absorption of a given

amount of a vessel’s berthing energy. Unlike fenders with circular designs a leg fender with a given

height can be shortened or lengthened to vary the amount of energy absorbed and reaction

produced. As with most buckling column fenders the HZF Leg Fender has fully encapsulated internal

flangs that allow fenders to mate with the berths and the steel frontal panels.

6. HI-TECH “AT” FENDERS (HAT) & “XAT” FENDERS (HXAT)

HAT FENDER

HXAT FENDER

HAT and HXAT arch fenders are based on a simple buckling column design that provides improved

energy and reaction characteristics over simple cylindrical fenders. The arch fenders are designed to

provide rugged and reliable service for berthing small to medium size vessels. Both the HAT and HXAT

fender have a rubber face with a corresponding high friction factor. This surface will tend to damp the

motion of small ships during swell or wave conditions. In conditions that require a fender face that

does not mark or requires a low friction surface the HXAT fender can be provided with a UHMW-PE

frontal pad or connections to attach to a steel panel.

7. HI-TECH “MT” FENDERS (HMT)

The HMT fender was developed to provide greater energy to reaction ratio than normal arch fenders to

accommodate the increasing size of berthing vessels. Modern cargo vessels are also more lightly

constructed than those of previous generations. This lighter construction means they can withstand

lower hull pressures and the increased width of the HMT fender provides significantly lower hull

pressure than a corresponding height of normal arch fender. HMT fenders are produced in sizes that

can accommodate moderately sized cargo vessels.

8. HI-TECH CYLINDRICAL FENDERS (HCT)

The HCT is the oldest form of rubber fender for berthing ships. Cylindrical fenders whether large or

small have been used in ports all over the world and are still used today. Being relatively easy to

install using simple chain attachments, they are adaptable for use on piers with poor quality concrete

that will not allow anchors for other fender.

9. TUG-BOAT FENDERS Tugboats, because of their working environment, are typically fendered to provide a cushion between

them and the vessels they are assisting. These fenders can either be intended as pushing surfaces on

the front of the tug or to protect the two vessels from accidental contact due to close working

conditions. Hi-tech provides several fenders that can be used in either or both of these scenarios.

These are listed as: “D” Type fender (HDF, Square Fender (HSF), Square +UHMWPE Fender (HSUF),

“W” Type Fender (HWF), Keyhole Fenders (HKF) & Tug Cylindrical Fenders (HTCT). We can provide any

size as per requirement.

11. ROLLER FENDERS Roller fenders are specialized fenders intended to guide vessels into tight spaces such as canals, lock

entrances or ship dry docks. They are also used to protect corners of piers where vessels are turning

close to the structure. The fenders are designed to give little resistance to rolling contact rather than

absorb the energy of berthing. Please feel free to contact Hi-tech representative for more details and

to help you select the right choice of the fender and size.

12. HI-TECH OIL BOOMS (HOB)

Oil Booms are barriers used to contain oil spills in the oceans. Floating property of oil on water helps

the boom round up and contain oil and keep it from expanding and contaminating beaches, islands,

and wetlands. The boom has a weight, the floating tube, and a tall wall-like structure to help keep the

oil contained. Oil Booms come in many shapes, sizes and are also made from different types of

materials as per their use. Selection and use of HOB depends on the function of boom, adequacy of its

usage, prevailing weather conditions, durability, storage and transportation.

Hi-tech offers different types of oil booms (HOB) which are actually solutions for oil spill response.

These oils booms are used for many oil spill response such as oil containment, oil diversion, oil

deflection or oil exclusion. Hi-tech offers three types of oil booms viz. External float type (HOB-EX),

Self Inflatable/ Pneumatic type (HOB-SIP) & Foam Type (HOB-FT).

13. HI-TECH MARINE PROTECTION BARRIERS (HMPB) Security of marine assets has become necessary in recent times and hence a marine protection barrier

is essential security equipment for NAVY ships and other vessels.

Hi-tech protection barrier is laid as a line of demarcation to protect the maritime facilities. The fill

system is extremely durable and environment friendly. HMPBs are equipped with Inflatable rubber

floats, center tension assembly, underwater protection metal grid, security alarm system, positioning

marking buoys and illumination during night to mark NO-ENTRY zone.

boat landing system that can absorb energy in

both deflection and shear. The shock cells can

be manufactured with or without an eccentric

bumper ring. The basic principle of a shock

cell is the adhesion of rubber to two concentric

steel tubes.

14.3 DIAPHRAGM CLOSURE (HDC) The diaphragm is a dome of reinforced rubber

clamped into a ring which can be made a part of the

leg or skirt sleeve. Diaphragm closures seal the legs

and skirt sleeves of off shore platforms during

transportation and installation to provide buoyancy

and keep out foreign material.

They are designed and tested to withstand the

hydrostatic pressure exerted during jacket flooding

operations. As standard procedure Hi-tech tests all

diaphragms to 1.5 times the operating pressure but

marina basin.

22. HI-TECH MARINE GROWTH PREVENTER (HMGP) Marine growth on the submerged members of offshore structures/jetties

increases the section area of the submerged part which thereby alters the

surface characteristics of the offshore structures. This alteration in surface

characteristic contributes to the environmental loading and weight on the

offshore structure. Hence prevention of marine growth requires protection of

system/apparatus of offshore structures and jetties for proper functioning which have their parts

submerged in the ocean water and are prone to marine fouling.
