INDUSTRY ARTICLE
Starting as soon as Forewind was awarded the development right to the Dogger Bank Zone, the vessels surveyed more than 40,000 kilometres in transects, while trained observers recorded their findings using the industry accepted collaborative offshore wind research into the environment methodology.
Fred. olsen United’s 132m jack-up vessel Brave Tern, installed the first mast in February and the second in September 2013.
THE DEVELOPMENT STAGES The acceptance of the first application by the Planning Inspectorate is the result of the largest offshore survey programme ever
The second meteorological mast being installed in September 2013
Fish ecology surveys underway at Dogger Bank AERIAL SURVEYS
The aerial surveys also covered more than 200,000 kilometres in transects, with a bank of four digital video cameras attached to an aircraft recording all objects within a 200 metre wide swathe. The videos were reviewed on return and images of birds and marine mammals marked, before being identified by experienced ornithologists and marine mammal observers from the Wildfowl and Wetlands Trust Consultancy.
ONSHORE SURVEYS
Onshore surveys have been underway in parallel with the offshore, taking into account local wildlife populations of newts, reptiles, mammals and bats, as well as studies related to all other areas within the environmental statement including traffic, archaeology and boreholes.
All the while Forewind has also been working on the installation of two meteorological masts, which will provide essential wind, wave and other weather information, as well as marine traffic data for the Dogger Bank development.
METMAST FOUNDATION
The foundation used was the innovative suction installed Bucket Foundation, designed by Universal Foundation, and selected as part of the Carbon Trust’s Offshore Wind Accelerator programme, which takes the best concepts for offshore wind turbine foundations from design to deployment.
undertaken in the UK offshore wind industry and one of the most comprehensive and thorough environmental impact assessments to date. however Forewind’s work continues.
The volume of work required to finalise the development consent order application for the first stage of development will also be repeated for the next two Dogger Bank development stages – Dogger Bank Teesside A & B and Dogger Bank Teesside C & D.
Dogger Bank Teesside A & B will comprise two offshore wind farms - each with a maximum installed capacity of up to 1.2GW – and both connecting into the national grid at the existing Lackenby substation near the wilton Complex. The final pre-application consultation process for this stage will run through November and December with the application scheduled to be submitted to the Planning Inspectorate in Spring 2014. Dogger Bank Teesside C & D will follow approximately 12 months behind.
GREAT ACHIEVEMENTS SO FAR BUT STILL A LONG WAY TO GO while the Forewind team can celebrate its achievements to date, there is still much work to be done to meet the target’s set for the Dogger Bank development.
