This project seeks to identify and validate concepts that deliver significant savings against the structural, ancillary and installation components of offshore HVDC platforms. The project will engage with upstream and downstream stakeholders to establish and prioritise potential areas of improvement for cost reduction and develop innovative strategies to deliver savings. The methodology will seek to identify several concepts and develop the best ones to validate the potential savings and demonstrate technical feasibility. The final concept(s) will be hydro-dynamically tested to ensure that the proposed solution has suitable hydrodynamic performance. The project will build on knowledge of existing HVDC platform projects in non-UK waters. The concept will be based on the generic requirements impossed by the electrical plant associated with HVDC rather than be fixed to a single supplier.
