D1 Belfast
Harbour
The D1 project at Belfast Harbour,
the UK’s first purpose-built offshore
wind logistics facility, involved the
construction of a new 500m quay wall
structure and a deep water berth.
The quay wall was constructed over
both land and water, utilising 32m
long, 1.6m diameter tubular piles in
combination with 22m long PU22 sheet
piles. The combi-wall was tied back
to a reinforced concrete anchor beam,
supported on 367 raking tubes. These
tubes were 30m long and 760mm
diameter and were anchored to the
rock. A total of 30,000m³ of concrete
was used during the construction of the
relieving slab which is supported on
780 CFA piles of diameter 750mm.
Works also included the dredging of
600,000m³ of material for the new deep
water berth and approaches and its
disposal at sea. An additional 20,000m³
of contaminated dredged material
was treated on site prior to disposal.
Approximately 150,000T of rock armour
was placed beside the quay wall as
protection for the seabed.
The contract also entailed the
development of 50 acres of hinterland.
A total of 900,000m² of geotextile and
1,000,000T of aggregate was used in the
construction of 200,000m² of heavy duty
unbound pavement for the hinterland.
General services were also installed to
supply the future renewables hub. The
D1 project - the largest ever undertaken
in the 400 year history of Belfast
Harbour – was completed in just over
one year.

Seaforth
Client
Mersey Docks and

Value
£11 Million
The existing Seaforth Passage gives
access for cargo and ferry vessels into
the Royal Seaforth Dock within the Port
of Liverpool. Due to a proposed increase
in the size of vessel using the port, it
has become necessary to widen the
passage by approximately 20m.
The dock structure was built in the
1970s and comprises reinforced
concrete diaphragm walls approximately
38m apart and 100m long. These
walls house steel sector gates which
were designed to close the passage
between Gladstone and Royal Seaforth
docks. Extending underneath the
passage, there is a 3m diameter siphon
connecting the Liverpool storm drainage
system with an existing outfall. There
are also link ducts containing the HV,
LV, communications and water supplies
essential for the operation for the port.
The widening project included
installation of a new piled quay wall
behind the existing western diaphragm
wall. The new quay was a combi wall
with sheet pile infills tied to a sheetpile
anchor wall. A permanent cofferdam
now provides access to the existing
siphon for its extension beyond the line
of the combi wall. A new, prefabricated
steel 1m diameter U-Tube extends
between service culverts on the eastern
and western sides, diverting the
existing services around the works area.
Floating plant was used to demolish
the western diaphragm wall and the
420T western sector gate. The gate was
then cut into sections using explosives
placed by divers and lifted to shore for
recycling.
All works were completed whilst
maintaining shipping through the
passage.

EDF Energy Nuclear
Generation Ltd
Value
£2.6 Million
Farrans was contracted by EDF Energy
Nuclear Generation Ltd to carry out
repairs to the cooling water outfall
structure of Heysham No.1 at the
licensed nuclear site at Heysham.
The cooling water is discharged from
the cooling water culvert into a channel
predominantly formed by two parallel
rows of frodingham steel sheet piles
which run westwards to the deep water
channel.
Generally, the condition of the structure
had continued to deteriorate due to
corrosion – as would be expected for a
steel structure in a marine environment.
In numerous locations, there were
areas of suspected Microbially Induced
Corrosion (MIC) which had led to
significantly higher corrosion rates.
During 2008 and 2012, a significant
number of the sheet piles failed above
berm level, in addition to the formation
of less significant holes and leaks.
The repairs which Farrans undertook
involved the installation of replacement
sheet piles along sections of the
structure which were failing. New piles
were landed next to the existing piles to
form a “box”. These were subsequently
bolted together and sealed using
concrete. The piles were driven into
place from a jack-up barge and, in order
to maximise productivity, works were
being carried out 24 hours a day. The
project was completed on budget, to
programme and the satisfaction of EDF
Energy Nuclear Generation Ltd.

Granton
Harbour Wall
The Granton Harbour Wall
development was part of a multi-site
regeneration of some of Edinburgh’s
industrial heartland. The Harbour
Wall was one of a number of projects
successfully carried out by Farrans as
part of the long-running multi-agency
scheme.
The new wall was required to reclaim
a new development footprint from the
existing sheltered anchorage for small
boats at Granton Harbour.
At 200m long, the quay wall was
constructed of new sheet piles
shipped directly to the site, handled
and installed from the Farrans’ barge,
the “Claude Monique”. The front
wall is anchored by tie rods to a new
anchor wall.
As part of our bulk earthworks
exercise, we worked with our Client to
identify local fill sources and test the
material, ensuring its viability for use
as marine structural fill.

8. The Montrose Port Authority Deep
Water Berth Project involved the
redevelopment of the berthing and
cargo handling areas at the South
Quay. It included the removal of the
existing collapsed quay wall and
reconstruction of 230m of heavy duty
combi wall and service bases for the
offshore oil and gas industry.
The existing quay walls at Berths 16
and 17 had collapsed and the contract
required their removal from the seabed
prior to the installation of the new
quay wall. We used underwater drilling
and blasting techniques to remove
the collapsed sections before building
the new quay wall as a combi-wall
structure. The concrete deck was
strengthened by a matrix of hard
driven concrete piles within an area
specifically designated for heavy lift
purposes.
Utilities and bunkers on the quayside
were also constructed and included
water, gas, oil and lighting. To provide
a facility for deep draft vessels, a total
of 27,000m³ of material was dredged
from the berth. The dredged material
included estuarine alluvium and
boulder clay deposits and was safely
transported to a licensed disposal site
at sea.

Pointhouse
Quay
Situated at the mouth of the River
Kelvin, Pointhouse Quay was part of
Glasgow’s Masterplan to rejuvenate
the dockland area. The quay is
now the site of the new Transport
Museum for Scotland, as well as the
permanent berth for the Tall Ship
‘Glenlee’.
Works involved installing a steel
piled combi-wall anchored back to
anchor blocks. Working from land,
we installed 106 tubular piles at a
raking angle. These supported the
anchor blocks which were then
secured by a rock anchor and drilled
concentrically down the raked pile.
The anchor block was then securely
fastened to the rock, some 30m
below the surface.
Due to the size of the tubes on the
combi-wall, the support formwork
for the cope needed to be specially
designed. The support mechanism
was manufactured by welders and
tested within our plant yard in
Belfast. This system proved to be
very effective and when stripped,
could be used repeatedly for cope
construction.

Montrose Port Authority
Value
£5.7 Million
This project involved the design and
construction of a new quay structure
at Berth 6, Montrose Port, to upgrade
the existing berth. In order to ensure
the existing quay was fully operational
during the course of the project, the
works were designed to be carried out
in two phases.
A 180m long combi wall was
constructed at the front face of the quay,
utilising tubular and sheet piles. The
tubular piles were a combination of
1.2m and 1.4m diameter piles, 29m in
length, with AZ18 sheet pile infills. The
front wall was connected to a sheet piled
anchor wall, 180m long, using tie rods.
The quay deck structure covers an
area of 4800m2
. The slab structure
is supported on precast piles and
incorporates heavy lift areas. A new
drainage system was installed on the
quay, including a drainage channel,
manholes and outfalls for surface water
drainage.
In order to facilitate the service
requirements for the new quay structure,
we provided a service trench, with
special access covers and ducting. The
contract also included the installation
of new quay furniture including ladders,
fenders, bollards, etc.
In addition to these works, 8000m3
of
material was dredged from the channel
in front of the quay to deepen the
berthing pocket.

11. The Warrenpoint Harbour
Development project responded
to the need to deepen the existing
main berthing facility at Warrenpoint
Harbour which is situated on the
mouth of the Newry River.
As part of this design and build
appointment, we installed 320m of
combination piled wall along berths
4 and 5. This deepened the harbour
area by 2m, allowing large vessels to
use the dock facilities.
The final work on this scheme
included the construction of a new
110m long rock bund breakwater
which runs from the existing custom
house quay.
The electrical services and water
supply on the quayside were
also upgraded, along with the
replacement of all the quay furniture.
