Description

Using regulator guidance, this Navigational Risk Assessment (NRA) identifies and analyses both the base case and future case risk associated with the development of Dogger Bank Creyke Beck A and B. Analysis and collision risk modelling was undertaken based on three scenarios as follows: Dogger Bank Creyke Beck A in isolation, Dogger Bank Creyke Beck B in isolation and Dogger Bank Creyke Beck A and B together.

The NRA includes an assessment of existing navigational features including metocean data, maritime incidents and a marine traffic survey (AIS and Radar) to identify the baseline environment. The elements of the Rochdale Envelope have then been assessed against the base case to identify areas or activities that may see a change in risk following development of Dogger Bank Creyke Beck A and B.

Consultation was undertaken with stakeholders, regular operators identified from the marine traffic survey and European Shipping Associations. In order to address the cumulative issue in the Southern North Sea, Forewind joined Hornsea and East Anglia developers in forming the Southern North Sea Offshore Wind Forum (SNSOWF) and further consultations were undertaken as part of this work.

The marine traffic survey identified seven main routes operating within a 10 nautical mile (nm) buffer around Dogger Bank Creyke Beck A and B with the majority of vessel types transiting on these routes being tankers and cargo vessels. Fishing activity was recorded across much of the sites with a high density of vessels to the west of Dogger Bank Creyke Beck B during the sand eel fishing season (April, May and June). The level of recreational vessel activity was noted as being very low.
