Offshore foundation works

PTC Vibrodrivers combine smart design and powerful technology.

These robust Vibrodrivers are highly reliable under extreme working conditions

and are suitable for all types of offshore foundation works requiring to drive or extract:

• Large diameter piles.

• Anchor piles.

• Dolphin piles.

• Mooring piles.• Offshore wind turbine foundations: Tripods

Jackets

Monopiles

For more than 80 years PTC has been mastering vibration technology

and developing innovative pile driving solutions: the Vibrodrivers.



On board of the ship, the new Portable Pipelay

System n°2, designed and manufactured by

Joseph Paris (Fayat Group company). The PPS2 is

capable of handling hoses of several « kilometers »

in length, needed to reach the oil deposits in the

brazilian deep sea.

PTC in a few words:

• All PTC machines are manufactured in France.

• ISO 9001 2008 certied company.

• 85% Turn over are export sales.

• Sales in more than 50 countries.

Research and Development at the heart of PTC

Since its foundation in 1928, beginning with the invention of the poker vibrator, PTC has specialized in developing

vibration techniques.

PTC’s innovations have played an important role in the development of the Vibrodrivers: it was the rst company

to launch the hydraulic Vibrodrivers in the early seventies, the rst to introduce the high frequency Vibrodrivers

and as well the inventor of the high frequency Vibrodrivers with controlled variable amplitude. In early days, PTC

research studies aiming to reduce the impact of piling techniques on the environment, have resulted

in several new patents :

• The Vibmaster, a monitoring system that controls vibration and soil particle velocity,

and also registers multiple driving parameters.

• The Ecomode, an electronic module included in PTC power packs that reduces fuel consumption

and reduces exhaust emissions to the environment.

Valuable synergies among the FAYAT group

In 2004 PTC joined the FAYAT Group, the world leader in compaction equipment

and France’s leading family-owned construction business (No. 1 in steel works and

4 th biggest building and public works company) . FAYAT’s industrial activities position it as

a full liner in road-building equipment. The company’s designing and manufacturing

businesses also apply to handling and hoisting equipment and pressure vessels, where

60% of the products are sold in other countries.

Present in all 5 continents, the 118 FAYAT group companies employed more than

17000 people and achieved a turn over of 2.7 MM € in 2010.

Synergies among the Fayat group strengthen PTC’s possibility to offer an even larger

range of services and solutions. PTC and JOSEPH PARIS, a Fayat company recognised

for its lifting equipment and offshore structures for pipe line works, are working

together to propose integrated solutions in offshore projects.



Pile driving and pile extraction

PTC vibrodrivers are capable of vibrating large diameter piles through vertical vibrations, which are produced

by the eccentrics located in the vibrator’s gearbox.These vibrations cause the adjacent ground to shift reducing

the friction between the soil and the pile. Thus allowing a fast and easy penetration.

Vibrodrivers can also extract piles using the same principle, via the pulling force of the Vibrator and the crane.

Extraction works do not require any additionnal modication in the equipment.

The vibrations generated by the Vibrodriver are transmitted to the pile through the clamp, which plays the key role

of connecting the Vibrodriver and the pile.

GEAR

The eccentrics mounted in the gear box

are ordered in pairs. Each eccentric pair

turns at the same angular velocity and in

opposite direction, hence producing a vertical

vibration. Both eccentrics generate centrifugal

forces fc . The horizontal components fh

are offset at the same time that the vertical

components fv are added, resulting in

centrifugal force Fc . The eccentric moment

and the centrifulgal force are fundamental

Vibrodriver’s parameters that determine

the Vibrodriver performance.

YKE

Contains high absorption elastomers,

which are the result of PTC research

to reduce vibratory emissions to

the crane and the environment.

Vibratory pile driving is based on the principle of reducing

the friction between the soil and the pile through vibration.



PER PACKS

Hydraulic power packs supply

the energy required by the Vibrodriver.

CLAMPS

The link between the Vibrodriver and the pile.

The clamp grabs and secures the pile during

the handling and driving phases. Several clamps

and customised clamping accesories are developed

by PTC to allow perfect adaptation to all types of piles.

PILE

A wide variety of piles can be driven by the Vibrodriver:

• Large diameter piles

• Anchor piles

• Dolphin piles

• Mooring piles

• Offshore wind turbine foundations: tripods, jackets, monopiles



Under water piling

PTC Vibrodrivers can work to a depth of 100 m providing the same

pile driving performance.

Standard Vibrodrivers can work up to 15 m depth without any pressurisation system.

Vibrators working under water are equipped with a special pressurisation system

designed by PTC for under water piling works.

Pile extraction

The strong line pull of PTC Vibrodrivers allows,

efcient pile extraction works and accurate pile positioning.

Harbour and bridge jobsites often need to begin using the Vibrator to extract from

water the old structures, before starting the new foundations.

For both jobs, extraction and pile driving, PTC Vibrodrivers have proven for years to be

highly productive.

An accurate and precise pile positioning is another advantage of the Vibrodrivers.

The driving angle can be corrected at any time to guarantee perfect compliance

to the jobsite requirements.

Multiple piling possibilities to adapt to the diversity of technical demands

and extreme weather conditions encountered in offshore applications.



Raked piles

PTC Vibrodrivers can drive piles up to a rake of 1:1 (45°).

Standard PTC Vibrodrivers can drive piles up to a rake of 15° without any modication.

Vibrodrivers needing to drive piles up to a rake of 1:1 are equiped with a special technology

developped by PTC for raked piles.

Tandem Vibrators

An alternative solution to increase power

and performance.

• Enables bigger pile diameter.

• Two-in-one vibrators.

45°

15°



Customised clamps

To adapt to any size and type of pile.

1 - Pile layed on the barge.The Vibrator is shifted towards the pile

and the clamps are fastened, securing the pile.

2 - The crane starts to lift the Vibrodriver and the pile.

Safety is ensured with a gripper at the swiveling point.

Thus, the pile can’t slide during lifting.

3 - The pile is vertical.

The gripper can be released and the pile moved

to the driving position.

e develop customised solutions,

to meet the fast evolving needs of our customers.

Pile handling solution

PTC’s innovative solution for easier and faster pile handling and positioning.

Optimising noise emissions in tougher conditions.

Vibrodrivers pitch the pile and rapidly drive it to the

maximum possible depth. Afterwards, the hydraulic

hammer drives the pile the last meters.

• Start with Vibrodriver and nish with hammer.• Reduces sound exposure (noise x driving time) .

• Faster driving, productivity gains.

The highest noise level of any of the methods

as impulsive acoustic energy is created upon

footprint

PTC power packs running with the patented Ecomode system (standard in 900CO and optional in 1200C)

provide the same Vibrodriver performance but consuming less fuel.

Thanks to the reduction of fossil fuel consumption, the polluting gas emissions are as well reduced up to 20%.

The use of Biodegradable oil is an option available for all PTC Power Packs. We highly recomend its use to protect

the faune and ore around the job site.

Both the Ecomode and the Biodegradable oil, positively impact in the reduction of the CO2

footprint of the jobsite.

PTC has made the choice to

propose modular power packs

to run its Vibrodrivers for their

numerous advantages:

• Higher reliability of the equipment.

• Spare parts availability.

• Quick replacement and repairs.

• Economies of scale.

• Easy maintenance.

PTC manufactures the largest range of hydraulic

The Ecomode allows the engine to permanently run at optimal speed without modifying the ow and the frequency
