Gravity Base Design

Royal BAM Group has achieved a Worldwide first having been awarded a contract to design, fabricate and install five full-size gravity base foundations for wind turbines of 41.5MW in capacity off the Northumberland coast.

The contract has been awarded to BAM by EDF Energy Renewables via SPV Blyth Offshore Demonstrator Ltd and utilises leading edge technology, the first of its kind to be built in the World.

The foundation design will utilise ‘self-installing’ technology, which has been developed by two BAM companies, BAM Nuttall Ltd and BAM Infra bv. The design is being undertaken by BAM Infraconsult.

The project itself will be a demonstration project to prove the viability of this approach to installing gravity base foundations in the offshore environment for future wind farms. The project is due for completion during summer 2017.

Commenting on the award, BAM Nuttall’s Head of Civil Engineering Malcolm Corlett stated ‘This is a very significant milestone not just for BAM but for the wider offshore wind sector. An opportunity to demonstrate the potential for self-installing concrete gravity bases to provide economic foundations for large wind turbines in deeper water. Following five years of intensive work refining our design and method of construction we now have a live project to demonstrate our technology and bring new skills and opportunity to the North East of England.’
