Offshore submerged foundation applications that benefit from high density MagnaDense
Gravity Based Structures (GBS): MagnaDense enables you to build platform legs and sub-sea bases:
- with more weight
- and with an enhanced ability to resist sea currents
- and to withstand icebergs.
Gravity-Based Wind Structures: the industry prefers to make pre-cast foundations as light as possible. Mainly, so they are easier to handle and cheaper to transport. At their final position on the sea, these will be ballasted with the high density aggregate to increase the weight of the foundation.
SPARS: a spar is a floating platform. This platform is used either for oil and gas storage or as a floating foundation for wind turbines. For SPARS you can use MagnaDense in two different ways:
- as a loose ballast which you can pump into place with a water slurry
- in concrete as a stabilizer around the base of the SPAR
Anchors for wave & tidal energy devices: to keep the wave power machinery in place MagnaDense can be used as an aggregate in concrete or as loose ballast in the anchor, foundation or counterweight for the device.
Concrete mattresses: the large ‘bed’ of concrete blocks held together in the shape of a mattress is used to keep pipelines at sea bottoms. You can make the high density concrete blocks with MagnaDense as a heavy aggregate.
MagnaDense in underwater constructions
Because MagnaDense is non-toxic and doesn’t react to seawater, it is an ideal material for underwater usage as a gravity-based ballast. When you use this as loose ballast inside your construction, it is possible to recycle the MagnaDense. You can watch the below video which explains this more in detail.
