Offshore foundation

Related applications: Gravity foundation

The very nature of where offshore structures are placed means that their foundations needs to withstand harsh water conditions and undersea currents.

These gravity foundations also need to have considerable weight in order to withstand the motions of the sea and the stresses imposed by the structure’s use.

The value of dense concrete for underwater construction work is demonstrated by the Archimedes Principle.  MagnaDenseTM  filled concrete has a proportionally higher submerged weight than standard concrete of the same volume. This means that concrete made with MagnaDenseTM can help to significantly decrease costs from the reduction of concrete volume required for any given design weight of a foundation.  A pre-cast gravity foundation will therefore be easier to handle and cheaper to transport out to its designated position. 

Other benefits of using MagnaDenseTM include the concrete being resistant to abrasion thereby increasing underwater lifetime and as a non-toxic naturally occurring mineral it is friendly to the undersea environment. Furthermore a distinct advantage of using MagnaDenseTM  in offshore gravity foundations is that it is unreactive in sea water.
