The foundation provides the anchoring from the tendons to the seabed. The foundation must withstand high lateral and tensile loads. The foundations, and subsequently the mooring, are permanent.
There are basically two types of foundations:
Gravity based, concrete:
Keeps the tendons in place by the weight of the foundation (mostly used in shallow water). However, the size of this type of foundation will be very large due to high tension forces and submerged weight of the anchor blocks.
Piled foundation, steel:
