IHC Offshore WindConcept development

A number of developed concepts by IHC BU’s:• Fully assembled turbines on a jack-up vessel• Jacket installation system• Blade installation tool – 3 blades• Monopile installation• Floating vessel - fully assembled turbine installation

Patent pending

Concepts to be further developedin cooperation with the industry

Some facts on sizes / forces / speedS 1200 Hydrohammer driving a steel pile:

�• Ram m= 60 tons

�• Ram is lifted up in 1s over 1m drop height

�• Ram accelerates at 2g down in 0,5 s to max speed

�• Ram speed at anvil v = 6,33 m/s = 22,8 km/h

�• Energy E = ½ m*v2 = 1200 kNm

�• Cycle rate is 40 blows/min at full energy

�• Contact time (energy transfer) of ram and anvil ป 4,5 ms�• Speed of shock wave in pile = 5200 m/s or 18720 km/h

noise in air = noise under water ?

18 dB(A) reduction can bring us to acceptable levels

Noise reduction:

Forward actions underwater sound mitigation methods

1 Scale testing in IHC basin, double walled vacuum shell Completed at IHC yard October 2009, noise reduction 20-40dB

2 Open water test with live hammerCompleted March 2010
