FWP 2017 l Lucile HERITIER, Port of Brest “Port facilities, supporting every stage of floating wind development”

1. A NECESSARY PARTNERSHIP PORT - INDUSTRIAL
PORT OF BREST – BRETAGNE REGION

2. 2
TO WELCOME FLOATING WIND CONSTRUCTION
ACTIVITY, A CHALLENGE FOR A PORT
§ To have wide surfaces for the construc2on of machines
§ To load out the float
§ To assemble the turbine quayside
§ To store the floa2ng wind turbines

3. 3
AT BREST PORT, A DEDICATED TERMINAL IS UNDER
CONSTRUCTION TO FACE THESE ISSUES
Drydock 2
338m x 55m
Drydock 3
420m x 80m
MRE Terminal

TO LOAD OUT THE FLOAT
MRE quay:
380m long
-12m deep

8. 8
TO LOAD OUT THE FLOAT
§ Without a strong partnership, the
port cannot build or reserve a
specific infrastructure
Dry dock n°3
Brest Port
KaTupali port
shipliU
(43mx200m)
KaTupali port slipway
160m

9. 9
§ To invest in a specific infrastructure includes risks:
§ Obsolescence due to growing dimensions of the float
§ Serial produc2on impacted by the capacity
§ Dedicated tool speaking of serial produc2on
§ Dependence on the port
TO LOAD OUT THE FLOAT

10. 10
METTRE À L’EAU LE FLOTTEUR
Brest port favours rolling/
skidding or liUing.
⇒ We are building a heavy load
quay
⇒ We want to be able to
welcome any technology,
any project
⇒ Our drydocks can be used for
short dura2ons

11. 11
TO LIFT THE FLOAT
§ Impact on the port:
§ Quay resistance for a terrestrial crane
⇒ In Brest a very high quay resistance to
localised loads
§ Impact on the industrial:
§ Limita2on of the float weight
§ Float designed to be liUed
§ Float designed to be rolled
DEME, Rambiz
Up to 3300t
Mammoet
PTC 140-DS
Up to 3200t

12. 12
TO ROLL/SKID THE FLOAT
§ Impact for the port:
§ Construc2on areas resistance
§ Impact for the industrial:
§ Float to be build on supports
§ Float to be reinforced on support points
SPMT
Skidshoes ALE

13. 13
TO ROLL/SKID THE FLOAT
§ Impact for the port :
§ To limit waves quay side
⇒ In Brest the quay favours lower waves but there is no
breakwater
§ Impact for the:
§ To handle 2dal range
⇒ In Brest 2dal range can reach 8m at 1,92m/h speed
§ Float designed to be corbelled or limita2on of its
dimensions
§ Flooding in good nau2cal condi2ons
⇒ In Brest we have a naturally sheltered an deep basin
in front of the port

Skyjack 3000 - ALE

14. 14
TO ASSEMBLE THE TURBINE ON THE FLOAT QUAYSIDE
§ Quays and know-how to welcome the heavy load supplies
§ Spaces quayside for buffer stocks
§ A heavy duty quay for a heavy load crane
§ A quay dedicated for the serial produc2on
§ A quay able to welcome the float:
§ Floa3ng moored to the quay
§ Laying on the ground in front of the quay

15. 15
TO ASSEMBLE THE TURBINE QUAYSIDE ON THE FLOAT
FLOATING
§ Impact for the port:
§ Quay layout to limit waves
§ Quay structure to enable the float to lean on it
§ Quay protec2ons compa2ble with the float geometry
§ Bollards posi2on and resistance according to the float mooring
system
§ Impact for the industrial:
§ Float geometry enabling the mooring
§ Reinforcements on mooring lines points
§ Ballast system adapted to 2dal range and speed
§ Stability to handle waves

16. 16
TO ASSEMBLE THE TURBINE QUAYSIDE ON THE FLOAT
GROUNDED
§ Impact for the port:
§ Depth adapted to the float draught
§ Flatness of the ground
§ Repeatability of grounding opera2on
§ Impact for the industrial:
§ Ballast system adapted to depth
§ Float structure designed to bear grounding

17. 17
STOCKER LES ÉOLIENNES TERMINÉES
Issues to handle :
• Large surfaces of basins,
• Environmental impact to study as for open see farms,
• Landscape modifica2ons to be acceptable.
TO STORE THE FLOATING WIND TURBINE ONCE BUILT

18. 18
A NECESSARY PARTNERSHIP PORT-INDUSTRIAL
§ Port issues impact the very design of the wind turbine
§ Port must adapt but machines have to be adapted to port reali2es
§ The port should be involved early in the industrial studies
§ A partnership ongoing : Brest Port and the Groix-Belle-île pilot
floa2ng wind farm
§ To cope with the challenges, a global port offer : Brest – Lorient –
Nantes St Nazaire
