TYPICAL EXPERIENCE THROUGH NORTHSEA
PORTS IN OWF CONSTRUCTION
1. Belgium : Port of Ostende :
used for Thorton bank construction : phase 1 and 2 (foundations + WTG)
is then upgraded to a renewable offshore base to serve the futur Belgian OWF but also south UK and France can be
served for construction and O+M
BELGIUM : PORT OF OSTENDE 2007-2011
was primary used for the 1st phase of Thorton bank project for
the preparation of the 6 gravity base foundations in 2007 and
2008
Was also shelter harbour for involved marine vessels at that time :
- Dredging vessels
- Tugboats
- crew vessels
- Barges and pontoon
Focus was on the construction site of gbf which required a significant upgrade to a heavy load quay and backyard

4th largest seaport of Belgium
Lost a ferry line in 2011 -- > extra space logistics in OWF
In view of upcoming OWF projects in vicinity (< 250 km) :
Belgium : 1.6 GW planned till 2020
France : 2 GW
South East UK : 10.5 GW planned
Focus on development offshore wind hub creating local
employment
Initiative between Port of
Ostende , Flemish investment
fund and some other companies
in a public private partnership :
REBO NV : investment of 25/30
mio euro in stages
BELGIUM : PORT OF OOSTENDE

(TWB)
80 Nos. of 5 MW wind
turbines (AREVA Wind
M5000 type)
1st phase: 40 wind turbines,
installation between 2011
and 2013
Our scope : pre-piling,
grouting WTG logistics and
WTG Installation
DESCRIPTION PROJECT
40 AREVA Wind M5000 wind turbines
1 turbine = 8 separate components:
- 1 S3 tower section
- 1 S2 tower section
- 1 S1 tower section
- 1 Nacelle
- 1 Hub
- 3 blades
In total 320 components, all manufactured in
Germany by AREVA Wind
FAS delivery by AREVA Wind
Logistics by DEME
SCOPE DESCRIPTION OF
LOGISTIC PACKAGE
1 Rotor
Logistics sites:
- Stade: 120 blades
- Cuxhaven: 23 S1 tower sections and
23 S2 tower sections
FABRICATION SITES WTG PARTS
- Bremen: 17 S1 tower sections and 17
S2 tower sections
- Bremerhaven: 40 S3 tower sections,
40 nacelles and 40 hubs
- Eemshaven: base port

Offshore assembly rotor facilitates storage onshore of WTG parts:
WTG INSTALLATION CONCEPT DETERMINES
PORT LOGISTIC SCENARIO
Voyages grouped into campaigns with relatively short pre-notice periods
for S1 & S2 logistics and blade logistics
Possibility to accommodate changes in the schedule without extra
costs
2 fully equipped pontoons (S3, nacelle & hub logistics), one dedicated
tugboat, assisting tugboats if necessary
Redundant system (if one pontoon has breakdown, transports can
continue)
Emergency power supply for nursing the WTG components is available
SPMTs and elephant feet
no need for expensive cranes at the storage areas
DEVELOPMENT OF A FLEXIBLE
SOLUTION
Cuxhaven & Bremen, in total 80 tower sections
Load-out & load-in with mobile cranes (tandem
lift configuration)
Nearshore transports with general cargo vessel
4 x S1 and 4 x S2 for each voyage
Easy seafastening method with lashing chains
attached to stiffening beams
Local transport with SPMTs
Storage on steel supports and loadspreading
mats
S1 & S2 TOWERSECTION LOGISTICS
Bremerhaven, in total 120 components
Load-out & load-in with crawler crane
Nearshore transports with seagoing pontoons
3 x S3, 3 x nacelle and 3 x hub for each voyage
Easy seafastening method with stoppers and
shim plates
Local transport with SPMTs
Storage on steel supports and loadspreading
mats
S3, NACELLE & HUB LOGISTICS
Stade, in total 120 blades
Load-out & load-in with mobile cranes (tandem
lift configuration)
Nearshore transports with general cargo vessel
6 x blade for each voyage
Easy seafastening method with lashing chains
attached to the blade frames
Local transport with trailer truck
Storage on loadspreading mats
BLADE LOGISTICS
Long-time storage of WTG components on steel supports and
loadspreading mats
AREVA Wind is responsible for this long-time storage in Eemshaven (e.g.
maintenance of the components)
Power supply requirements during storage are significant and expensive!
Simultaneous with WTG installation campaign:
- Onshore rotor star assembly
- S1 & S2 tower section up-ending
ONSHORE LOGISTICS EEMSHAVEN
Inspection and Test Plan:
- Certificate of Compliance
- Weather Assessment Reports
- Daily Site Reports
- Checklists
Nacelle tilt restrictions
roll & pitch logger on pontoons

POINTS OF ATTENTION OF WTG
LOGISTICS 1. Interface between WTG fabricator , logistic provider, port operator
2. High QA/QC program to be followed
3. Needed port space for WTG storage heavily influenced by installation
concept
4. Fabrication of different parts of WTG on different places logistic
scheme not to be underestimated and properly planned.
5. Logistic plan can be adjusted to project specific conditions :
in case of shortage of space :
1. Barge storage
2. Just in time delivery of parts
Increased costing !
DEDICATED LOGISTIC CENTERS FOR
OWF 1. Requirements to portfacilities depends of project specifications :
Type of foundation / turbine
Installation concept and equipment
Size of the windfarm , amount of windfarms to be served
2. Development dedicated port logistic center for OWF can lead to
substantial benefits to project construction efficiency.
3. Such development require public support/interest and should exceed
specific projectboundaries
4. OWF logistic centers in ports create large local added value with respect
to employment ( maritime repair-workshops, cranes, tugs,
helicopterservices,.)
THANK YOU FOR YOUR ATTENTION
