Ballast for wave and tidal power generators

MagnaDense can be used either as loose ballast or in dense concrete to provide a stable foundation to ballast wave and tidal machines to the seabed.

Wave and tidal technology is used to capture energy by ocean surface waves. The wave power machinery can be kept in place by an anchor, foundation or counterweight made with high density concrete or filled with heavy loose aggregate such as MagnaDense.

The high density of MagnaDense will ensure that:

  • the wave energy converter maintains the placed position
  • the ballast has a long lifetime due to abrasion resistance in addition to the aggregates non-reactivity with seawater
  • you can be flexible with your design

Anchors for wave & tidal energy devices made with high density concrete remain at the bottom of the sea

MagnaDense for offshore

Wave and tidal technology is not yet widely spread. There are a few projects worldwide which are experimenting the use of wave and tide to generate energy. However the use of MagnaDense as a ballast or mixed into high density concrete is already used in a lot of other offshore applications such as:

Take a look at below video to see how MagnaDense is mined and what benefits it can offer to your offshore projects.
