The increase in size o container ships has meant
that the current deep-sea berths at the container
terminal (Berths 204 to 207) can no longer
accommodate our large vessels simultaneously.However by
combining berths 201 and 202 it will
create approximately 500m o quay with a 16m
water depth, which will enable the terminal to
again be able to accommodate our o the larger
vessels. When works are nished, the total handling
capacity o the port will be increased rom 2 million
to 2.7 million TEU a year.
The project has been the subject o an extensive
environmental study, which carried out an
assessment o the efect o construction activities on
the surrounding area, and included a comprehensive
monitoring programme during the construction
phase. The result o the study identied that the
noise emitted rom Vibrodrivers was acceptable,
despite that the use o percussive piling operations
was restricted. These environmental demands
encouraged the use o Vibrodrivers to drive the
piles as ar as possible.
Thereore they were used or the initial pitching o
the piles and the subsequent driving o the piles,
to achieve the maximum penetration possible. Once
practical reusal was achieved with the Vibrodrivers
an impact hammer was used to drive the piles to the
required toe level.
The reconstruction o the 500 m-long quay wall
required the installation o a combined wall. This
combi wall was made o 149 tubes (38m long and
1820mm diameter) and three PU22 sheet piles
installed between each tube.
Associated British Ports (ABP) appointed
Contractor VolkerStevin the design and
build contract for the reconstruction
and deepening of berths 201 and 202 in
Southampton Port. This project will
enable the Port to accommodate the
current generation of large container
vessels at their loaded draught.

SouthhamptonPort expansion, England.
The tubes were initially driven with the PTC 200HD
Vibrodriver and then driven to level with an IHC S280
Impact hammer, which was equipped with a noise
mitigation shroud. The Vibrodriver was powered
by power pack 1200C (806 kW) equipped with
ecomode system, which reduces uel consumption
up to 20%.
To drive the PU22 sheet piles in triples, the
contractor chose to initially drive them with a
PTC 65HD Vibrodriver equipped with triple jaws,
with nal backdriving carried out by a BSP CX110
hydraulic impact hammer.
VolkerStevin, decided to use a 3 rd Vibrodriver, the
PTC 130HD, which was used to drive and extract
the spud legs or the piling rames. The 130HD and
the 65HD, were both powered by an additional PTC
1200C power pack equipped with Ecomode system.
