Contents

•  Spatial plans •  First offshore windfarms •  Second round applications •  Preparing the third round


Spatial plans

•  National Spatial Strategy (Nota Ruimte) •  Structure plan of Military Areas (Structuurschema Militaire Terreinen) •  Policy statement Water Management (Nationaal Waterplan)

–  water quality management, fresh water –  safety against flooding –  anticipating climate changes –  recreation –  inland water transport

•  Integral Management Policy North Sea (IBN)


National Spatial Strategy

Spatial planning policy •  Vision statement for spatial development into

2020/2030. •  North Sea: key area of the National Ecological

Network. –  strengthening the economic significance,

linked to –  preservation and development of nature

and landscape values

(elaboration of the North Sea paragraph)


Integrated Management Plan North Sea (IBN) •  Elaboration of North Sea paragraph of the Water Plan •  Coproduction of Ministries of

–  Transport, Public Works and Water Management 1

–  Agriculture, Nature and Food Quality 2

–  Housing, Spatial planning and Environment3

–  Economic Affairs4

–  Defense 2,4):Ministry of Economic Affairs, Agriculture and Innovation

1,3):Ministry of Infrastructure and the Environment •  Functions:

–  shipping –  oil and gas –  sand –  fishing –  nature –  renewable energy


Water quality


Shipping

Clearways •  corridors free of obstacles

for the passage of ship traffic.

•  Logical routes, connecting the existing TSSs.

•  All oil&gas rigs have to stay out of these areas.


Wind energy areas

•  Existing •  Permits •  Prospect areas


Clearways and traffic density


Egmond aan Zee / NoordzeewindQ7 / Amalia

Egmond aan Zee / NoordzeewindFirst offshore windfarms

•  Egmond aan Zee (2006) 36 x 3 MW = 108 MW

•  Q7 Amalia (2008) 60 x 2 MW = 120 MW


Second Round Wind farms

•  Boundary condition: no constructions in the clearways •  No turbines within 12 nm from coastline •  Financial support for maximum 1000 MW •  Invititation to apply for financial support:

–  Apply for permit –  Environmental impact study

- including shipping safety effects - SAMSON model had to be used

•  Ministry of Economic Affairs would choose the most cost-effective initiatives that received a permit

•  Result: 80 applications!


2nd round applications


Finally, 12 permits

Key issues: •  Ecological impact •  Safe helicopter flight paths •  Shipping safety

Permits round 2


Ecological impact Natura 2000

•  Distance to lesser seagull colony •  Underwater noise

–  Disturbance of seals and fish larvae –  No pile driving January - July

Shipping safety / efficiency


Shipping safety – points of discussion

•  Does SAMSON produce representative figures? –  Influence on radar image –  Influence of ‘complex traffic situations’ –  Visual disorientation in combination with anchorage area and on-

shore lights •  Minimum safe distance between shipping route and wind farm? •  Which accident probability can be accepted

–  Political damage –  Economical consequences –  Casualties

•  Legal procedures

BARD/TYPHOON BUITENGAATS 300 MW

BARD/TYPHOON ZEE-ENERGIE 300 MW

ENECO Q10 120 MW

AND THE € WINNERS ARE…


3rd Round

•  Political goal: 6000 MW to be created by 2020 •  Indicate possible areas in Integral Management Plan North Sea

•  Coastal area determined by clearways •  Modification of shipping routes affects granted permits of 2nd round

Cost – effectiveness (subsidies for production)


Formal Safety Assessment

•  Navigational Risk Review –  Hazard workshop –  SAMSON

•  Variant 5 favourable –  Less complex traffic pattern in Maas Junction –  Accident frequency (SAMSON) no significant change –  Combined with new TSS IJmuiden


Cost – effectiveness (shipping)


Total costs


Current proposal for IMO approval


Current state

•  Modification of shipping routes – proposal to IMO •  Modification of granted round 2 plan •  New government since 2010 •  No funds/subsidy for round 3 •  New energy policy expected 2014/15
