Assessing seabed mobility potential for Morgan and Mona offshore wind farms

Supporting cable route selection with seabed behavioural characteristics


Morgan and Mona are planned fixed offshore wind farms in the eastern Irish Sea. When completed, they will have a combined potential generating capacity of 3GW, sufficient to power approximately 3.4 million UK households.

As part of the development of the wind farm sites, Energie Baden-Württemberg AG (EnBW) and bp required detailed information on seabed mobility potential for both projects.

Solution and delivery

To inform understanding of the behavioural characteristics of the seabed across both project sites, ABPmer drew on outputs from its ongoing detailed metocean studies for Morgan and Mona, recent and historic seabed surveys, and geophysical data collected specifically for the projects.

High resolution hydrodynamic and sediment transport modelling were used to map the detail of long-term regional scale sediment transport pathways.


The work will be used to help support export cable route selection for both projects, as well as inform the ongoing wind turbine foundation and array/export cable design process. The wind farms are expected to be fully operational by 2029.

We are proud to have a significant and successful track record in projects like Morgan and Mona, having been involved in many of the major offshore wind farm developments in UK and European waters.

ABPmer assists the renewables sector throughout the project lifecycle; from site selection and feasibility, through environmental impact assessment and consenting to engineering design, construction and operation and maintenance.
