Balmoral HexDefence™

Fixed wind turbine scour protection typically involves the installation of a layer of material around the base of the monopile to prevent sediment erosion. This can be made of various materials including rock, concrete or a specially designed geotextile fabric. The layer is placed on the seabed around the monopile to dissipate the energy of the fluid flow and reduce erosion rates.

These measures need to be carefully monitored to avoid damage to the turbine, seabed and any associated cabling. The costs involved in this process, along with the carbon footprint implicated with extra quarrying and vessel time for installation, is significant.

To resolve these issues Balmoral developed Balmoral HexDefence™, a unique scour protection system that integrates seabed protection and flow reduction to reduce offshore operational costs and potential cable failure.

The globally patented system eliminates the requirement to dump rock, instead providing a non-invasive approach to protecting the monopile structure and the immediate surrounding area.

The lightweight GRP construction and streamlined installation method makes it easy to install without the need for additional vessels resulting in an improved carbon footprint for all operations.
