Offshore Wind Round 4 Navigational Risk Assessment

Delivering constraints analysis to support the development of six Round 4 Areas

Determining the most appropriate place for a development like an offshore windfarm requires an understanding of all constraints that might impact that decision.

A major factor is understanding the implication for vessel traffic of the site development. This also includes implications for offshore industries with marine traffic such as aggregates, disposal at sea, renewable energy and the hydrocarbons sector.

ABPmer was asked by an offshore wind developer to undertake a constraints’ analysis screening exercise of six Round 4 Areas. We investigated the potential development of each site, considering the most viable area for development.

To ensure the assessment included all necessary considerations our specialist team applied buffers to each Area of Search. We then considered existing shipping routes derived from Automatic Identification System (AIS) data, fishing vessel activity and recreational use.

We also outlined key factors that would affect the consenting process, including likely stakeholder engagement requirements, the applicability of Marine Plan Policies and interactions Directives and regulations.
