Challenge
ScottishPower Renewables and Vattenfall Wind Power began working on an equal collaborative partnership in 2009 to develop capacity for offshore wind generation off the East Anglian (UK) coast. East Anglia ONE, with a capacity of 714MW, was the first project to be selected for development within the East Anglia zone. The project achieved consent in 2014 and was awarded a Contract for Difference by the UK Government in 2015 with the lowest levelised cost of energy. In February 2015, ScottishPower Renewables became the sole developer on East Anglia One.
Building a project of this scale requires a wide variety of technical competencies. DNV was ScottishPower Renewables engineering partner on the project, providing a wide range of technical services throughout the development of the wind farm.

- Wake modelling of the impact of neighbouring projects on the energy production and loads.
- Development of wind turbine tender documentation.
- General technical advisory support.
- Cable route options study.
- Transport & installation analysis.
- Client representatives at various stages of the project development phase.
Outcome
The client benefited from receiving a diverse range of market leading advisory services from a single provider, to support the development of this landmark project. DNV deployed its extensive experience from across the offshore wind industry to provide specialist knowledge and professional support services where required. DNV provided expert technical support throughout each phase of the project to date and in a number of fundamental packages. These include wind turbines, foundations, geotechnical, operations & maintenance strategy, transport & installation strategy and met mast.
