How do we get 30,000 of these unitsinstalled offshore in 2030?

EU target 20 for 20

30 for 30

Install in several steps:

Install foundation

Install transition piece (if applicable)

Install steel tower

Install turbine: nacelle, hub, blades

several sequences and assemblies possible

Often done with jack-up

OFFSHORE WIND

Future offshore wind

Scenarios for Europe (www.EWEA.org)40 150 GW installedoffshore wind in 2030

total power demand in 2030: 1,158 GW

OFFSHORE WIND

Future offshore wind installation

Challenges:

cost reduction

larger turbines

faster and safer installation

deeper water / future foundations


22/26

OFFSHORE WIND


Challenge: cost reduction

Required for the whole industry. For installation:

Faster installation process

Optimized, fit for purpose vessel design

Innovations for foundations and installation processes


23/26

OFFSHORE WIND


Challenge: faster and safer

Install more turbines in available weather window by:

Optimized logistics & industrialized repetitive process

Feeder vessels? solve offshore transfer

Faster deck handling and assembly logistics

Installation in one piece?

OFFSHORE WIND


Challenge: deeper water / future foundations

Handling of larger structures and weights at deeperwater cheaper alternative for jack-up + crane?

Floating turbines: new installation procedures and

dedicated vessels (or just standard tugs?)

Tri-floater

OFFSHORE WIND

In summary a possible future scenario for Europe:

30,000 turbines in 2030with 30 installation units
