RWE Renewables has appointed global maritime consultancy ABPmer to support the design of the Awel y Mor offshore wind farm with a capacity of up to 1100MW in the Irish Sea off Wales.
ABPmer assesses sediment mobility and scour potential at the wind farm site off the North Wales coast.
The work will be used to help support export cable route selection, as well as inform the ongoing design process for the wind turbine foundation and export grid/cable.
ABPmer will analyze oceanographic data from its Seastates metocean database, recent and historical seabed surveys and geophysical data specifically collected for the project, to map the behavioral characteristics of the seabed at the wind farm site and the corridor of export cable.
High-resolution modeling of hydrodynamics and sediment transport is also used to map details of sediment transport pathways at long-term regional scales.
Heidi Roberts, ABPmer Project Manager, said: “Drawing on our local knowledge of Awel y Mor and adjacent wind farms as well as OWF’s expertise across the UK, our specialists carry out an analysis detailed statistics, modeling and interpretation of oceanographic and geophysical data.
“Our seafloor mobility hazard mapping tools help RWE understand current and future seabed form migration, providing vital information in support of cable route selection and design. »
A GIS analysis of coastal data will also be undertaken to consider the potential for coastal erosion and vertical change in beach levels at the landfall over the life of the project, supporting the selection and design process of the landing.
Detailed design will continue through 2022, with the wind farm targeting 2030 to be fully operational.
