1 Presentation Logistic solutions for the installation of offshore wind farms Captain / Graduate Economist Andreas Wulf

2 Agenda - German Offshore Projects - Situation today - Transportations - Installations - Lookout

3

4 - Transportations - For transportation of offshore construction pieces usually North Sea Standard Barges (90 m x 30 m x 6 m [L x B x H]) will be used, especially for foundation structures - For single segments smaller pontoons also be qualified (nacelles, tower sections etc.) - Paying attention of pontoon height is vital concerning the transshipment (RoRo vs. crane transshipment)

5 - Also so called wet towages, for example for offshore substations, possible - Pontoons will then only be used as supply equipment - For special operations submersible pontoons will be essential, advantage is that weight of components become lower the more pontoon will be sumbersed, i. e. crane capacity can also be lower money will be saved

6 - Impressions Unloading of a rotor blade

7 Unloading of a nacelle by SPMT

8 Unloading of a nacelle by SPMT, closer view

9 Loading of a nacelle by SPMT and floating crane

10 Loading of a nacelle, SPMT operation onshore

11 Loading of a nacelle, idea for the proportion

12 Loading of e-units for OSS BARD 1

13 Nacelle for offshore wind farm BARD Offshore 1

14 Kugelbake completely loaded with e-units and nacelles

15 Arrival of towage in Cuxhaven, barge is loaded with piles

16 Loading of tower sections in Bremen, first section already transshipped

17 Loading of tower sections in Bremen, 2nd one is on its way

18 Loading of tower sections in Bremen, 2nd successfully transshipped

19 Loading of piles by floating crane Samson (capacity of up to 900 t)

20 Loading of piles by floating crane Samson, in the background you ll see the seafastening installed on the barge

22 - Installations - For installation of offshore wind farms, i. e. offshore wind turbine generators as well as substations etc., jack-up barges respectively floating cranes are compulsory - Installation units need to have high crane capacities to enable the transshipment and installation at site - Due to high water depths in the North Sea the legs have to be long enough, soil conditions etc. has to be considered

23 - Impressions Transportation and afterwards installation of an offshore substation Source: by EnBW

24 HLV RAMBIZ in Cuxhaven, capacity is up to 3,200 t

25 Skidding operation in Klaipeda, OSS BARD 1 will be skidded on the barge T.O.W. III

26 Due to a rail system, OSS will be transshipped to the barge

27 This picture interferes a good feeling for the proportion of the OSS

28 Mission successfully accomplished

29 Loading of a tripile in Cuxhaven by gantry crane of CSC (subsidiary of BARD)

30 Another two tripiles successfully transshipped for the offshore wind farm BARD Offshore 1

31 OSS BARD 1 in foggy weather, in the background you ll see an installation unit

32 OSS BARD 1 in sunny weather, helicopters are transferring the crew for maintenance

33 Tripiles offshore are waiting for their installation

34 Jack-up barge THOR is also used for the installation of offshore wind components in the offshore wind farm BARD Offshore 1

35 Before tripiles can be installed, piles will be picked up and rammed into seabed

36 Piles will be inserted in a mounting frame

37 After ramming the piles, tripiles will be provided

38 Installation unit WIND LIFT I is lifting the tripiles

39 Crane of WIND LIFT I is going to install the tripile
