OFFSHORE WIND INSTALLATION
Present installation methods
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 installation
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
Future offshore wind installation
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?)
