AqualisBraemar LOC identifies marine traffic risks for German wind farms

AqualisBraemar LOC (ABL) has supported the German authorities in identifying the risk of marine traffic to expected offshore wind development in the North Sea between 2020 and 2040. ABL undertook a navigational risk assessment (NRA) that involved the collaboration of all coastal states and the study also concluded with risk mitigation measures.

The North Sea study, which was conducted for the German Ministry of the Interior, Building and Community, focusses in particular on areas with existing or prospective offshore wind farm and maritime renewable development across the whole of the North Sea.

ABL’s scope of work included a detailed marine traffic study and the identification of qualitative characteristics within the main shipping routes in the North Sea, projecting traffic growth over the next 20 years. It also included a risk assessment to identify areas in the North Sea with the highest concentration of collision, allision and grounding risk, including modelling of traffic corridors.

The study, that involved the collaboration of all coastal states in gathering information about their maritime spatial plan, concludes with risk mitigation measures in the form of alternative routing, where the planned offshore installations disrupt the current traffic pattern.

“Navigational risk analysis can play a significant role in the early identification of optimal windows for offshore construction, installation and maintenance operations for the energy sector. This study is a good step in mapping out where marine traffic poses a risk to the busy ongoing and prospective construction plans for European offshore wind,"
said Diego Cerquenich, Master Mariner at ABL

The study aims to strengthen the partnership between North Sea coastal states and reinforce a collective approach to identifying and resolving future challenges facing offshore wind developments.

It also contributes to the revision of the German Federal Maritime and Hydrographic Agency (BSH)’s maritime spatial plan. The maritime spatial plan provides analyses that contribute to approval procedures for infrastructure development in the German exclusive economic zone of both the North Sea and the Baltic Sea.

“The German offshore wind market is projected to play a leading role in the supply of carbon-neutral energy in Europe with a possible 40GW by 2040. It is therefore, critical that the local market remains competitive and that challenges to operation or development are mitigated early on, to ensure optimised operability of wind assets and reinforce their bankability,”
commented Christoph Ruck, General Manager of ABL in Germany.
