PORTS/LOGISTICS IN OWF CONSTRUCTION

1. Belgium : Port of Ostende :

2. Netherlands : Port Of Eemshaven :


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

was then upgraded to a dedicated full service port of offshore wind

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 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,.)
