OFFSHORE WIND 2015 – TRENDS


OFFSHORE WIND 2015 – TRENDS

• Nearshore Offshore

• Waterdepth increase

• Turbine size

• Environmental impact

• Europe Global industry

• Contract set up

• New technologies & equipment

• Safety


NEARSHORE OFFSHORE

• Increasing water depth Impact on foundations

• No impact on wind farm layout!

Average water depth and distance to shore for online, under construction and consented offshore wind farms

(Bubble size represents the total capacity of the wind farm)


NEARSHORE OFFSHORE

Typical fixed offshore foundations


NEARSHORE OFFSHORE

• Monopiles XL monopiles (>1000 Tons)

at limit of manufacturing capacity

requires heavy lifting equipment

upgrade piling hammers

• Other foundations become economic

• Gravity Base Foundations

• Jacket

• Floating turbines?


NEARSHORE OFFSHORE

= logistic concept has changed • Cargo on installation vessel Less vessels but large(r) size

• Harbour requirements


JACK UP FLEET


INCREASED TURBINE SIZE • Range 6 – 8 MW

• Better performance GWh/year

(higher availability + increased output)

• Expected: lower O&M cost

• Larger vessels for Transport & Installation


ENVIRONMENTAL IMPACT • Particular attention for impact of offshore wind on eco system

Example: Noise Mitigation

• However; different regulations

o UK: Piling ban

o NL: No simultaneous piling operations

o GE: Noise level < 160 dB

• Requires innovative solutions

o Noise mitigation sleeve

o Bubble curtain

o …

EUROPE GLOBAL INDUSTRY

• Traditional countries o Denmark, Sweden, UK, Germany, Netherlands,

Belgium • Newcomers o Netherlands (revival), France, China, US, Japan

• Maybe: o Taiwan, Korea, India, …


HIGH TECH BUSINESS Evolving from ‘traditional’ marine works high tech industry

• Specialized equipment

• New technologies

Examples:

• Siemens Offshore Transmission Module (Alternative to HV Substation)

• Noise Mitigation Systems

• High Wind Boomlock

Room for improvement on cable installation, foundation design, O&M,…


HIGH TECH BUSINESS

Boom Lock on Neptune


HIGH TECH BUSINESS

Blade Testing


SAFETY

Harsh environment

Very strict regulations

(~ Oil & Gas Industry)

- Vessel requirements

- Training of people (BOSIET, working at height, …)


CONCLUSIONS


CONCLUSIONS

• Offshore wind = Mature business

• Requires dedicated & specialized equipment

• High tech industry but still evolving!
